Vitamin C reduces cold severity
Vitamin C reduces the severity of common colds: a meta-analysis.
Most Relevant Research
We explored how vitamin C affects the severity of common colds through a comprehensive review of available studies. By including only randomized, placebo-controlled trials where participants received at least 1 gram of vitamin C daily, we aimed to investigate both the overall duration of colds and the intensity of symptoms experienced.

Our analysis found that vitamin C significantly reduced the severity of cold symptoms by about 15%. Interestingly, it appears that the benefits are more pronounced for those experiencing severe symptoms compared to mild ones. In specific comparisons, vitamin C didn’t substantially affect the duration of mild symptoms but had a notable impact on how long severe symptoms lasted.

This insight is crucial, as the common cold often leads to absenteeism at work and school, with more severe symptoms playing a key role in this setback. By highlighting vitamin C's greater effectiveness against intense cold symptoms, we suggest that future research should continue to look into how this vitamin can be utilized in managing cold severity.

Pleuran and Vitamin C aid asthma
Beneficial effects of pleuran on asthma control and respiratory tract-infection frequency in children with perennial asthma.
Most Relevant Research
We conducted a thorough evaluation of how vitamin C, when combined with pleuran, impacts asthma control and respiratory issues in children suffering from perennial asthma. The study was meticulously designed as a double-blind, placebo-controlled trial involving 230 children aged 7 to 17 years. This means that neither the participants nor the researchers knew who was receiving the active treatment or the placebo, ensuring the findings were reliable.

The results were promising, especially for children under 12 years. They showed significant improvements in asthma control compared to those receiving only the placebo treatment. Meanwhile, older children (12 years and above) experienced fewer respiratory infections with the combination treatment. Overall, by the end of the 48 weeks, a majority of children on the pleuran and vitamin C treatment reported better asthma control compared to those on the placebo.

While the combination of pleuran and vitamin C was indeed beneficial for managing asthma, we must note that the study did not specifically isolate the effect of vitamin C alone on allergies or asthma. Thus, it is hard to draw definitive conclusions about vitamin C's effectiveness independently from pleuran. However, the approach suggested that using these supplements together could offer a helpful boost in managing asthma symptoms.

Vitamin C alleviates cold sores
Topical treatment of recurrent mucocutaneous herpes with ascorbic acid-containing solution.
Most Relevant Research
We investigated how an ascorbic acid-based solution could help treat recurrent cold sores, also known as mucocutaneous herpes. This study was carefully designed as a randomized, double-blind, placebo-controlled trial, which helps ensure the results are reliable and trustworthy.

Participants used a strong solution of Ascoxal, rich in vitamin C, applied to their cold sores multiple times on the first day of the outbreak. We monitored various symptoms daily, including the severity of scabs, redness, and blisters, comparing the experiences of those using the vitamin C solution to a placebo group.

Our findings were promising: the active treatment resulted in fewer days with scabbing and less severe symptoms overall. Moreover, those using the vitamin C solution showed reduced persistence of scabs compared to the placebo group, along with a lower frequency of detected herpes virus after treatment.

In conclusion, this brief course of vitamin C treatment appears to have significant clinical benefits against cold sores, opening the door for future research on more extensive and frequent treatment regimes.

Pleuran and Vitamin C improve asthma
Beneficial effects of pleuran on asthma control and respiratory tract-infection frequency in children with perennial asthma.
Most Relevant Research
We conducted a thorough investigation to examine how vitamin C, when combined with pleuran (a natural extract from mushrooms), influences asthma control and respiratory health in children with partially controlled perennial asthma. Our study was a double-blind, placebo-controlled clinical trial involving 230 children aged 7 to 17 years, split evenly into an active treatment group and a placebo group.

Over a 24-week period, children in the active group received both pleuran and vitamin C, while the placebo group received vitamin C alone. It was exciting to find that children younger than 12 years who received the combination treatment showed notable improvement in their control of asthma symptoms compared to those on placebo. Additionally, older children in the active group reported fewer respiratory infections, an important benefit for their overall health.

By the end of our 48-week study, we saw a significant improvement in asthma control in a high percentage of children receiving the active treatment. Notably, this combination appeared safe, with no serious side effects reported. Overall, our findings suggest that while vitamin C's isolated effects can't be fully assessed due to its combination with pleuran, the combined treatment offers promising benefits for managing asthma in children.

Vitamin C's impact on constipation
Feasibility study for a fully decentralized clinical trial in participants with functional constipation symptoms.
Most Relevant Research
We conducted a fully decentralized clinical trial to explore the effects of vitamin C on constipation symptoms. Participants who experienced functional constipation were randomly assigned to receive either Lactobacillus with vitamin C or vitamin C alone over a two-week treatment period. The study allowed us to gather data remotely, which is quite innovative and accessible.

Looking specifically at the results from the group that received vitamin C, we observed that while there was an increase in the frequency of bowel movements compared to the control group, the isolated effect of vitamin C itself wasn't entirely clear. The combination treatment appeared to improve bowel regularity, but it was difficult to determine how much vitamin C contributed independently to these results.

Additionally, we found that about 67% of participants were diligent in tracking their bowel diary entries, which helped ensure the reliability of our findings to an extent. Yet, a significant portion of the records were not kept as scheduled, highlighting potential hurdles in data collection for decentralized trials.

Overall, our observations suggest that while vitamin C, especially when paired with Lactobacillus, may provide some benefits for those struggling with constipation, we should exercise caution before attributing all improvements solely to vitamin C.

Vitamin C lessens oxidative stress
Protective effect of vitamin C on oxidative stress: a randomized controlled trial.
Most Relevant Research
We aimed to discover how vitamin C supplementation affects oxidative stress in individuals diagnosed with chronic gastritis. In this study, we looked at 244 Japanese patients suffering from atrophic gastritis. They were randomly assigned to receive either 50 mg or 500 mg of vitamin C every day for five years.

After analyzing the results, we found notable differences between the two groups. The high-dose group experienced a significant decrease in reactive oxygen species (ROS), suggesting that vitamin C may help reduce oxidative stress associated with chronic gastritis. In contrast, the low-dose group reported an increase in ROS levels. These findings prompt further interest in how vitamin C can protect against oxidative stress in similar conditions.

Overall, our study supports the idea that higher doses of vitamin C could have a beneficial effect on oxidative stress, particularly in those dealing with gastritis. This insight opens avenues for considering vitamin C as a potential supportive treatment for managing oxidative stress-related issues in digestive health.

Vitamin C intake risks explored
Total, Dietary, and Supplemental Vitamin C Intake and Risk of Incident Kidney Stones.
Most Relevant Research
We examined the relationship between vitamin C intake and the risk of developing kidney stones in a large cohort. This study included a significant number of participants: 156,735 women from the Nurses' Health Studies and 40,536 men from the Health Professionals Follow-up Study.

Our findings revealed that total and supplemental vitamin C intake was linked to a higher risk of kidney stones in men, but there was no such association evident in women. Specifically, among men, those who consumed higher amounts of vitamin C had greater likelihoods of developing stones when compared to those with lower intakes.

However, dietary vitamin C did not show a connection with kidney stones in either men or women. This suggests that while supplements may pose risks for men, dietary sources of vitamin C might not have the same impact. Overall, the study indicates that we should be cautious about high vitamin C supplement consumption, especially for men, while highlighting that dietary intake appears safe.

Vitamin C shows promise in cancer treatment
Pharmacological Vitamin C Treatment Impedes the Growth of Endogenous Glutamine-Dependent Cancers by Targeting Glutamine Synthetase.
Most Relevant Research
We examined how vitamin C (VC) affects prostate cancer cells, particularly those reliant on glutamine for growth. Our study involved both prostate cancer cell lines and mouse models to understand the therapeutic potential of VC in this context.

We discovered that vitamin C has the ability to target an enzyme known as glutamine synthetase (GS), crucial for cancer cell survival. By degrading GS, VC induces oxidative stress, which appears to be detrimental to the cancer cells. We used both traditional lab approaches and more advanced imaging techniques to monitor the treatment's effectiveness, and found a direct correlation between GS levels and the cytotoxic effects of VC.

Not only did our experiments demonstrate that VC boosts the production of reactive oxygen species (ROS), but they also revealed that its effects could be mitigated by antioxidants, highlighting its mechanism of action. Particularly compelling were results from the mouse models, where VC treatment showed more pronounced effects in cancer cells overexpressing GS, suggesting a tailored approach to treatment might be effective.

Overall, these findings point to the potential of vitamin C as a novel treatment option for endogenous glutamine-dependent prostate cancers, emphasizing its role in targeting the metabolic pathways vital for tumor cell growth.

Vitamin C mitigates flu pneumonia
A new mechanism of vitamin C effects on A/FM/1/47(H1N1) virus-induced pneumonia in restraint-stressed mice.
Most Relevant Research
We examined the effects of vitamin C on pneumonia caused by the influenza virus, specifically the H1N1 strain, in mice under stress. The study found that when exposed to restraint stress, the mice experienced increased mortality and more severe pneumonia symptoms.

However, by giving them oral vitamin C at doses of 125 and 250 mg/kg, we observed a significant reduction in these severe outcomes. Vitamin C seemed to modulate the expression of certain genes related to the immune response, such as MAVS and IRF3, and increased the expression of NF-κB, which plays a key role in the body's antiviral defense.

Our research suggested that vitamin C's protective effects might stem from its ability to inhibit excess cortisol production in the adrenal gland, which is often elevated due to stress. By lowering cortisol levels, vitamin C may help reduce susceptibility to influenza infections, making it a potential ally during the flu season, especially for those experiencing stress.

Through these findings, we highlighted a new mechanism for how vitamin C can be beneficial during influenza infections, particularly for those who are feeling overwhelmed.

Vitamin C's role in arthritis management
The role of vitamins D, B12, C, and K in modulating inflammation and disease management in rheumatoid arthritis: a comprehensive review.
Most Relevant Research
We explored the role of vitamin C in addressing arthritis symptoms, particularly its effect on joint inflammation. Vitamin C is known for its antioxidant properties, and we found that it plays a crucial role in collagen synthesis. This feature is important as collagen forms the structural basis of our joints.

What excited us was the possibility that vitamin C could help reduce inflammation in patients with rheumatoid arthritis. Given that inflammation is a major factor in the discomfort and damage associated with this condition, any reduction could significantly enhance the quality of life for those affected.

However, while vitamin C shows promise due to its supportive functions, we must remember that the evidence concerning its direct effectiveness on arthritis specifically is still evolving. The correlation between vitamin C intake and reduced joint inflammation points to a beneficial role, but more detailed studies are necessary to solidify these findings and determine optimal dosages.

Overall, our review highlights that while vitamin C may indeed support joint health and aid in managing inflammation, further research is essential to fully understand its impact and to evaluate how it can be integrated into arthritis management strategies effectively.

Ascorbic Acid and Dizziness Study
Change of extracellular ascorbic acid in the brain cortex following ice water vestibular stimulation: an on-line electrochemical detection coupled with in vivo microdialysis sampling.
Most Relevant Research
We explored how ice water vestibular stimulation affects ascorbic acid (AA) levels in the brain, particularly in relation to dizziness. Using a method called in vivo microdialysis coupled with electrochemical detection, we monitored changes in extracellular AA in the primary somatosensory area of guinea pigs. Our study included 16 guinea pigs divided into three groups: one group received ice water stimulation, while the other two were exposed to warm water and ice water without vestibular input.

The results revealed that the concentration of extracellular AA increased in the brain following the ice water stimulation. This finding suggests that there may be neurochemical responses associated with AA that play a role in managing conditions like vertigo. However, while the study shows an intriguing relationship between AA levels and vestibular stimulation, it does not establish a direct link between vitamin C's effectiveness in treating dizziness specifically.

Overall, the insights gained from this research could help pave the way for further investigations into the role of vitamin C in vertigo-related treatments, adding a layer of understanding to its neurochemical functions.

Leg cramps treatment comparison
Calcium and magnesium status in pregnant women. A comparison between treatment with calcium and vitamin C in pregnant women with leg cramps.
Most Relevant Research
We explored the effects of vitamin C on leg cramps in a group of 60 pregnant women through a double-blind trial. Participants received either calcium or vitamin C (1 g twice daily) as treatment. Our observations revealed that there was no significant difference in clinical improvement between the two treatment groups.

Notably, 14 patients experienced complete relief from symptoms, while 27 reported significant improvement regardless of which treatment they received. Unfortunately, 17 participants found their symptoms unchanged, and only two noticed an increase in leg cramps during the treatment period.

Throughout the study, we measured serum levels of total and ionized calcium, total magnesium, and albumin, but these parameters did not show significant changes in either treatment group. We also didn’t identify any biochemical differences when comparing the effectiveness of vitamin C and calcium for alleviating cramps.

Ultimately, our findings suggest that vitamin C may not be an effective solution for leg cramps in pregnant women, as both treatments yielded similar results with minimal biochemical changes.

Vitamin C aids chloride transport
Effect of L-ascorbate on chloride transport in freshly excised sinonasal epithelia.
Most Relevant Research
We explored the effects of L-ascorbate, commonly known as Vitamin C, on chloride transport in sinonasal epithelial tissues. This research is particularly significant as it addresses the common condition of chronic rhinosinusitis (CRS) and its potential link to the function of the cystic fibrosis transmembrane conductance regulator (CFTR) — a key chloride ion channel.

During our investigation, we utilized freshly excised sinonasal tissues from both normal individuals and patients suffering from CRS. The tissues were carefully prepared and tested to understand how L-ascorbate influenced chloride secretion. Our findings revealed that the application of L-ascorbate notably enhanced chloride secretion in these tissues.

This is important because optimal chloride transport is essential for maintaining healthy mucosal surfaces and effective mucociliary clearance. Therefore, since decreased chloride secretion could lead to the worsening of sinus conditions, L-ascorbate presents a promising avenue for therapeutic intervention in improving mucociliary clearance for those affected by chronic sinus issues.

Vitamin C shows promise for UTIs
Network analysis, and human and animal studies disclose the anticystitis glandularis effects of vitamin C.
Most Relevant Research
We explored how vitamin C (VC) might help in treating cystitis glandularis (CG), a condition often linked with urinary tract infections (UTIs). Utilizing network pharmacology, we identified potential therapeutic targets of VC and the biological pathways it may influence to alleviate CG symptoms.

Our study involved both bioinformatic analyses and real-world observations, including human and animal studies. Through these methodologies, we pinpointed key biomarkers associated with CG, such as TNF-α, IL6, and c-Jun, which were notably elevated in patient samples.

Encouragingly, when VC was administered to mice with CG, we observed a significant decrease in these inflammatory markers in both blood and bladder samples. This suggests that VC could play a beneficial role in reducing symptoms associated with UTIs by targeting these key molecular pathways.

Vitamin C enhances immune response
Lysine vitcylation is a vitamin C-derived protein modification that enhances STAT1-mediated immune response.
Most Relevant Research
We delved into how vitamin C might influence cancer treatment, focusing on its effects on the immune system. Our findings revealed that vitamin C directly modifies certain proteins, leading to a new type of protein change called vitcylation. This process specifically affects a protein known as STAT1.

By modifying STAT1, vitamin C enhances its ability to signal for immune responses. We found that this modification occurs in both controlled environments and living cells, depending on factors like dosage and acidity. As a result of vitcylation, the action of STAT1 is improved, which activates important immune responses in tumor cells and boosts the expression of molecules that help the immune system recognize and attack cancer cells.

Interestingly, this research sheds light on the potential of vitamin C as a treatment that not only affects cancer directly but also empowers the body’s own defenses. These insights pave the way for new approaches to cancer therapy that leverage the immune system in conjunction with vitamin C.

Effectiveness of Vitamin C on Colds
Vitamin C for the common cold and pneumonia.
Most Relevant Research
We explored the effects of vitamin C on the common cold and pneumonia by examining a range of studies. Interestingly, research on animals suggests that vitamin C may have protective effects against infections. However, when it comes to preventing colds in the general population, taking more than 1 gram of vitamin C per day didn’t show significant benefits.

But there's a twist! Participants engaged in heavy physical activities saw their cold incidence reduced by half with vitamin C supplementation. Additionally, regular intake of 1 gram or more daily was linked to a 15% decrease in cold severity. While some therapeutic trials showed inconsistent results when vitamin C was taken after cold symptoms appeared, two studies did indicate that larger doses (6-8 grams per day) could effectively shorten the duration of colds compared to lower doses.

Our investigation also looked into pneumonia, but the studies were conducted in unique settings, such as a boarding school and military recruits. This makes it hard to generalize the findings to the wider population. Yet, some trials suggested benefits for pneumonia patients. Finally, the role of vitamin C in treating COVID-19 and sepsis remains unclear, with mixed results.

Given that vitamin C seems to alleviate symptoms and shorten the duration of colds, while being safe and affordable, it might be worth considering a dose of 6-8 grams per day to see if it helps at an individual level.

Vitamin C aids ear infection recovery
Malignant external otitis and polymorphonuclear leukocyte migration impairment. Improvement with ascorbic acid.
Most Relevant Research
We observed that malignant external otitis (MEO), a severe infection of the outer ear often found in elderly patients with uncontrolled diabetes, can significantly impair the body's defense mechanisms. In a notable case, a 58-year-old man struggling with MEO had faced months of ineffective treatments.

To delve deeper, we tested the function of his immune cells, specifically his polymorphonuclear neutrophil leukocytes (PMNs), which play a crucial role in fighting infections. Our findings revealed that his PMNs had difficulty migrating to the site of infection, a critical step for addressing such health issues.

We discovered that ascorbic acid, commonly known as vitamin C, could improve this migration defect in laboratory tests. In practical terms, after just one month of vitamin C treatment, the patient's chemotaxis results normalized, and remarkably, his ear lesions began to heal.

Even though the exact reasons for the PMN dysfunction remain unclear, possibly due to factors like age and diabetes, this case highlights the importance of assessing PMN function in MEO patients and suggests that immunomodulators like vitamin C might offer a valuable treatment pathway.

We explored the effectiveness of Rutin Forte, a treatment that includes long-acting vitamin C along with zinc and selenium, in managing rosacea, particularly in its erythematous stage. Our study included 30 patients—20 women and 10 men, aged 25 to 50—who were divided into two groups. One group received standard treatments like antibiotics and topical therapies, while the other group received the same treatments along with Rutin Forte for 2 to 3 months.

Over a 12-month observation period, we observed significant improvements in the group that received Rutin Forte. This group showed a notable reduction in erythema, the redness associated with rosacea, and intriguingly, there were no relapses of the condition. Conversely, the standard treatment group experienced recurrences of rosacea by the third month of follow-up, and their reduction in erythema was less pronounced.

This indicates that Rutin Forte, likely due to the vitamin C it contains, might play a beneficial role in treating and preventing rosacea symptoms, particularly in stubborn cases. Overall, our findings suggest that incorporating vitamin C into rosacea treatment can be quite effective.

Vitamin C aids anemia treatment
The Forgotten Disease in the 21st Century: Scurvy Outbreak in Hawassa Central Prison, Hawassa, Sidama, Southern Ethiopia, 2023.
Most Relevant Research
We observed a fascinating phenomenon related to vitamin C and anemia during a series of cases in a prison setting in Ethiopia. Specifically, we examined how scurvy, a disease caused by a lack of vitamin C, contributed to anemia among prisoners.

Our study focused on ten patients who were admitted for treatment, all of whom presented with some form of leg swelling or pain. After administering vitamin C in the form of ascorbic acid, we noted a significant increase in hemoglobin levels, rising from an average of 4.6 to 7.1 g/dL. This improvement indicates that vitamin C may play a crucial role in alleviating some anemia symptoms when the underlying cause is related to dietary deficiencies.

Additionally, through an observational study involving 67 other patients in the same prison, we confirmed that leg swelling and pain were common symptoms among those affected. With consistent therapeutic doses of vitamin C, all patients showed considerable improvement in their conditions.

Thus, we can conclude that vitamin C does seem to have a valuable effect on anemia caused by dietary deficiencies, particularly in high-risk environments like prisons. This finding encourages healthcare providers to remain vigilant about such nutritional deficiencies and highlights the importance of vitamin C in treatment.

Vitamin C may lower hypothyroidism risk
Association between total vitamin C intake and hypothyroidism among Hashimoto thyroiditis: National Health and Nutrition Examination Survey, 2007-2012.
Most Relevant Research
This study aimed to explore whether vitamin C intake could have an impact on hypothyroidism in individuals with Hashimoto thyroiditis (HT). We analyzed data from the National Health and Nutrition Examination Survey, focusing on participants from 2007 to 2012.

Our findings revealed an interesting association. We observed that higher total vitamin C intake was linked to a lower likelihood of hypothyroidism in those with HT. Specifically, individuals in the highest quartile of vitamin C intake had about 60% lower odds of experiencing hypothyroidism compared to those in the lowest quartile. This suggests that a greater intake of vitamin C, ranging from 4.57 to 1258.9 mg per day, might be beneficial for those affected by this condition.

Additionally, this association held true across different age groups and genders. Overall, we found that increasing vitamin C consumption might offer protective effects against the onset of hypothyroidism in Hashimoto thyroiditis patients.

Effect of Using Vitamin C Supplementation on Performance, Blood Parameters, Carcass Characteristics and Meat Quality of Broiler Chickens Under Heat Stress Condition: A Meta-Analysis.
Most Relevant Research
We explored how vitamin C supplementation affects cholesterol levels in broiler chickens, particularly under heat stress conditions. Through a thorough meta-analysis of 35 studies conducted between 1985 and 2023, we assessed various performance metrics, including blood parameters, carcass characteristics, and overall meat quality.

Our findings revealed that vitamin C significantly reduced cholesterol levels in the broiler chickens subjected to heat stress. Specifically, the study reported a notable decrease in cholesterol concentrations, with a standard mean difference of -0.976, indicating a strong beneficial effect of vitamin C in managing high cholesterol.

Additionally, we noticed improvements in body weight and average daily gain among chickens receiving vitamin C when compared to those that did not. While vitamin C did not significantly impact feed intake or breast meat quality, it emerged as a valuable antioxidant that can help lower blood triglycerides and reduce cholesterol, thus promoting better overall health and growth in broilers during stressful conditions.

Ultimately, this meta-analysis supports the use of vitamin C at a recommended dosage of 250 mg/kg as an effective growth promoter and antioxidant in broiler diets under heat stress, directly influencing cholesterol management.

Vitamin C may support bone health
The Positive Association of Plasma Levels of Vitamin C and Inverse Association of VCAM-1 and Total Adiponectin with Bone Mineral Density in Subjects with Diabetes.
Most Relevant Research
We explored the connection between vitamin C levels and bone mineral density (BMD) in individuals with diabetes. By examining a group of 74 diabetic patients alongside 26 age-matched non-diabetic controls, we focused on how vitamin C intake could potentially influence bone health. Our goal was to see if higher vitamin C levels were associated with improved BMD and whether this effect might be related to decreases in certain inflammatory markers like VCAM-1 and adiponectin.

The results were quite promising. We observed a positive link between circulating levels of vitamin C and BMD, suggesting that higher vitamin C might indeed contribute to healthier bones. Notably, we found that this beneficial effect was closely tied to lower levels of inflammatory markers in the blood. This indicates that vitamin C might help not just in improving BMD but also in lowering inflammation, which can be particularly valuable for those living with diabetes.

Overall, our findings highlight the importance of maintaining adequate vitamin C levels as a potential strategy to reduce the risk of osteoporosis in individuals with diabetes. Incorporating vitamin C in the diet could be a simple yet effective way to support bone health while also combatting underlying inflammation.

Vitamin C impacts glioblastoma progression
Vitamin C deficient reduces proliferation in a human periventricular tumor stem cell-derived glioblastoma model.
Most Relevant Research
We aimed to understand how a lack of vitamin C influences the growth of glioblastoma, one of the most aggressive types of brain tumors. Using guinea pigs, we tested the effects of a vitamin C-deficient diet on tumor growth caused by two different human glioblastoma cell lines, U87-MG and HSVT-C3.

Through this study, we observed that the absence of vitamin C significantly hindered tumor proliferation in both models. Notably, we found that vitamin C deficiency reduced factors associated with tumor growth, such as vasculature and immune cell infiltration, particularly in the HSVT-C3 cells, which are known for their stem cell-like properties.

Our findings suggest that vitamin C plays a crucial role in supporting tumor growth, and when absent, it can lead to a notable reduction in glioblastoma progression. This emphasizes the potential importance of maintaining adequate vitamin C levels for patient outcomes in brain tumor scenarios.

Vitamin C aids immune function
The clinical course of interstitial pneumonia alias chronic fatigue syndrome under the control of megadose vitamin C infusion system with dehydroepiandrosterone-cortisol annex.
Most Relevant Research
We examined how a combination of megadose vitamin C infusions and other treatments might help manage chronic fatigue syndrome, particularly in the context of interstitial pneumonia. Our findings were based on nearly a decade of treating patients, allowing us to gather valuable insights.

We observed that the long-term use of this treatment system significantly reduced the risk of pneumonia recurrence. It also appeared to help prevent the emergence of certain cancers in older patients suffering from interstitial pneumonia. Surprisingly, we found a link between interstitial pneumonia and an increased risk of depression, likely driven by prolonged glucocorticoid use.

While some patients showed promise under this treatment, those battling both interstitial pneumonia and depression responded less favorably. We suggested that increasing the amount of dehydroepiandrosterone in the treatment could be beneficial. Throughout our experience, we noted that the characteristics of chronic fatigue syndrome align closely with those of interstitial pneumonia, arguing against the notion that they should be viewed as separate conditions.

Overall, our approach not only alleviated inflammation but did not suppress the fibrotic processes in the long run. We made modifications to the treatment to lower the risks of vascular complications. The main strength of our treatment lies in creating a hormonal environment that helps tackle immune deficiencies using vitamin C, which faces lower resistance in the body compared to steroid treatments.

We explored the effects of vitamin C as a treatment for nausea and vomiting in pregnancy, also known as emesis gravidarum. Our study involved 111 participants, who were given either vitamin C-containing chewing gum, a placebo, or no treatment at all. We monitored them over two follow-up visits in early pregnancy to assess their symptoms.

While we measured various factors that could influence nausea—including hormone levels like hCG and DAO—our findings showed that the chewing gum did not effectively reduce nausea symptoms compared to the placebo or no treatment. Specifically, the vitamin C gum was not associated with any significant alleviation of nausea or vomiting.

Interestingly, we found that elevated levels of hCG were linked to increased nausea severity. In contrast, higher levels of DAO appeared to have a protective effect against symptoms. Additionally, elevated thyroxine and pyridoxine levels correlated with worsened nausea.

Overall, while vitamin C is often highlighted for its health benefits, our results suggest it does not play a significant role in treating nausea during pregnancy. This study highlights the complexities behind nausea in pregnancy, indicating that further research is necessary to uncover effective treatment options.

Antioxidant vitamin C improves endothelial function in obstructive sleep apnea.
Most Relevant Research
We evaluated how vitamin C might improve endothelial function in patients with obstructive sleep apnea (OSA). In our study, we compared 10 individuals with untreated OSA to 10 matched control subjects without sleep issues. We measured how well blood vessels reacted to increased blood flow, known as flow-mediated dilation (FMD), using ultrasound before and after administering vitamin C.

Our findings revealed a significant difference: baseline FMD was lower in OSA patients compared to the control group. However, after an intravenous injection of vitamin C, the FMD in OSA patients improved dramatically, reaching levels similar to those seen in the healthy controls. Interestingly, vasoreactivity in the control subjects remained unchanged.

These results suggest that oxidative stress might be a key factor contributing to the endothelial dysfunction experienced by individuals with OSA. The positive response to vitamin C opens up exciting possibilities for exploring antioxidant treatments in managing cardiovascular issues related to OSA.

Vitamin C impacts autoimmune response
Ascorbic acid alleviates rheumatoid arthritis by inhibiting the production of autoantibodies.
Most Relevant Research
We investigated how vitamin C, also known as ascorbic acid, might impact autoimmune disorders like rheumatoid arthritis. Through a study involving a mouse model of collagen-induced arthritis, we administered vitamin C or a placebo solution and observed the effects on the immune response and disease progression.

Notably, the research showed that mice given vitamin C experienced a significant delay in the onset of arthritis and a reduction in disease severity. This suggests that vitamin C can play a critical role in managing autoimmune conditions by minimizing the production of autoantibodies, which are harmful antibodies that mistakenly attack the body's tissues.

Our findings revealed that vitamin C reduced the number of plasma cells and decreased antibody production in response to immunization. This indicates that vitamin C influences the immune system's response at a cellular level, helping to prevent the emergence of autoreactive plasma cells. We also discovered that the mechanism behind this effect involved inhibiting the Stat3 signaling pathway, leading to less activation of autoreactive immune components.

Ultimately, these results highlight the potential of vitamin C not just as a nutrient, but as a strategic tool in managing autoimmune disorders. By simply supplementing with vitamin C, there may be a way to intervene positively in the progression of diseases like rheumatoid arthritis.

Most Relevant Research
We aimed to understand how Vitamin C could help with the toxicity caused by omeprazole, a common treatment for conditions like gastroesophageal reflux disease (GERD) and gastritis. During our study, we examined gastric cells from rabbits to see how Vitamin C, alongside other antioxidants, could protect these cells from damage caused by omeprazole.

We found that both omeprazole and another thiol-oxidant, monochloramine, significantly reduced cell viability. Interestingly, the toxicity from omeprazole occurred independently from monochloramine. However, we observed that using Vitamin C effectively protected the gastric cells from this injury, maintaining their function without interfering with omeprazole's intended effects.

This suggests that incorporating Vitamin C into treatment plans for people using proton pump inhibitors (PPIs) like omeprazole could be beneficial. Ultimately, our research highlights the potential of using antioxidants to mitigate the adverse effects often associated with medication for reflux and related conditions.

Proliferation capability of natural killer cells upon cytokines stimulation correlated negatively with serum lactate dehydrogenase level in coronary artery disease patients.
Most Relevant Research
We explored the effects of vitamin C on natural killer (NK) cell activity in patients with coronary artery disease (CAD). Our research involved isolating NK cells from 29 CAD patients and treating them with various stimulatory factors, including ascorbic acid—better known as vitamin C.

What we found was quite interesting: when NK cells were treated with ascorbic acid, there was a significant increase in their ability to proliferate. This meant that the NK cells were more active and potentially more effective in responding to threats in the body, which is vital for those dealing with heart conditions.

Furthermore, we measured serum lactate dehydrogenase (LDH) levels, discovering a negative correlation between LDH and NK cell activity. Higher LDH levels seemed to indicate lower proliferation capability in NK cells influenced by interleukins.

Overall, our study suggests that vitamin C could play a positive role in enhancing immune function in CAD patients by promoting NK cell proliferation. However, it's important to note that while vitamin C shows promise, further research is needed to fully understand its impact on cardiovascular health and immune regulation.

We investigated how vitamin C, specifically in the form of a 2% vitamin C solution spray, could help alleviate heartburn symptoms following Lugol chromoendoscopy, a procedure that involves staining the esophagus to better visualize abnormalities. In a well-structured study with 240 participants, we used a randomized, double-blind approach to compare the effectiveness of vitamin C to normal saline and sodium thiosulfate solutions.

Our results showed that vitamin C spray significantly reduced both acute heartburn symptoms and late discomfort when compared to the saline solution. Specifically, 33% of participants using vitamin C reported relief from acid regurgitation or heartburn, compared to just 15% with sodium thiosulfate. Additionally, patients noted an improvement in retrosternal pain, with 21% finding relief from the vitamin C treatment versus 9% from sodium thiosulfate.

Furthermore, vitamin C offered a quicker discoloration of the iodine-stained mucosa compared to saline, enhancing the overall experience of the procedure. These findings suggest that incorporating vitamin C spray into post-procedural care could be a helpful strategy for patients facing discomfort after undergoing Lugol chromoendoscopy.

Vitamin C intake reduces migraines
Association between dietary vitamin C intake and migraine in adults: A cross-sectional study of the National Health and Nutrition Examination Survey.
Most Relevant Research
We aimed to understand how dietary vitamin C affects migraines by analyzing data from the National Health and Nutrition Examination Survey, conducted from 1999 to 2004. In this survey, we identified adults who reported experiencing severe headaches or migraines over the past three months.

Our findings were quite revealing. Out of 4,101 participants, 702 individuals reported having a migraine, which represents about 17% of the group. We discovered an interesting trend: higher dietary vitamin C intake seemed to correlate with a lower likelihood of experiencing migraines. Specifically, participants with the highest vitamin C intake had a 36% reduced odds of suffering from migraines compared to those with the lowest intake.

We employed various statistical methods to confirm our results, including logistic regression and restricted cubic spline regression, which showed a clear linear relationship between vitamin C intake and the frequency of migraines.

Overall, this study suggests that increasing our dietary vitamin C might help minimize migraines, which is promising news for those who suffer from these intense headaches. However, as with all studies, further research is necessary to solidify these findings and fully understand the relationship between vitamin C and headache relief.

Vitamin C's uncertain heart benefits
Role of Vitamins in Cardiovascular Health: Know Your Facts - Part 1.
Most Relevant Research
We aimed to understand the role of vitamin C in heart disease and its potential cardioprotective effects. Vitamin C is renowned for its antioxidant properties, which means it fights off harmful substances in our body, potentially reducing the risk of heart issues.

Our analysis revealed that vitamin C could play a meaningful role in supporting cardiovascular health. While the evidence is promising, it is important to be cautious, as clinical studies have shown mixed results regarding its effectiveness.

So, while vitamin C might contribute positively to heart health, more solid evidence is required to fully confirm these effects. Overall, we learned that while there are positive indicators, we should be careful about over-relying on vitamin C as a sole preventive measure for heart disease.

Excellent! This vitamin C is the best on iHerb. All vitamins from this brand include probiotics, which are especially beneficial for those aged 40-50. They are completely natural and 100% digestible. I immediately feel more energised and it protects against viruses. For collagen and heart disease, I take it daily with my husband. We have tried various vitamin C supplements, but we will only purchase this one from now on.
