Dietary vitamin C reduces smoking-related cough
A survey of 4,300 young Norwegian adults examined whether dietary vitamin C intake relates to respiratory symptoms like cough and wheeze. Researchers estimated vitamin C consumption through questions about orange juice, oranges, potatoes, carrots, and tomatoes over the past year.
Among current smokers, those consuming more dietary vitamin C (395+ mg/week versus under 209 mg/week) showed reduced odds of morning cough and chronic cough. The protective effect was even stronger for ex-smokers experiencing wheeze. These benefits held true even after excluding people taking vitamin C supplements, suggesting the effect comes from food sources themselves.
The findings suggest that vitamin C's antioxidant properties may help counteract oxidative stress caused by smoking, potentially easing respiratory symptoms in smokers specifically.

An excellent tool for supporting immunity. Normally, I catch a cold and develop a chronic cough every spring and autumn. However, this spring, despite the poor weather, intense training, and strict diet, I have remained well. I credit this improvement to vitamin C. Even though recent studies suggest otherwise, the results speak for themselves. Everyone around me is sniffling, yet I feel fine. I take 2-5 grams daily and prefer buying from Now, as they offer the best value for money.

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.

During my pregnancy, I began taking Vitamin C after reading the Better Baby Book. I take 6g per day, using crystals for easier intake. Vitamin C has been shown to greatly reduce leg cramps, improve blood iron levels, and enhance baby health. I rarely suffer from leg cramps and have no stretch marks in my eighth month. It’s essential to adjust doses gradually, so I ensure I take my crystals daily in three doses.

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.

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.

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.

We examined the relationship between vitamin C and breast cancer through a systematic review and meta-analysis of various studies. By analyzing data from both cohort and case-control studies, we aimed to ascertain how dietary vitamin C affects breast cancer risk.
Our findings reveal an interesting trend. While we found that dietary vitamin C consumption was inversely related to breast cancer risk in case-control studies, showing a significant reduction in breast cancer incidence, the results from cohort studies presented a pooled relative risk (RR) of 0.99. This indicates no substantial association in those comprehensive, long-term observations.
Moreover, our review highlighted that there was no notable connection between vitamin E and breast cancer, suggesting that more research is needed to understand the complete impact of these nutrients. Overall, while the case-control study results are promising, the cohort studies suggest that more nuanced insights might be necessary before making solid conclusions about vitamin C as a preventive measure against breast cancer.

Vitamin C aids bronchitis resistance
We explored how supplementing the diet of broiler chicks with different levels of vitamin C, also known as ascorbic acid, impacts their resistance to infectious bronchitis virus. The goal was to determine whether this supplement could help improve their health by measuring the severity of tracheal lesions and the presence of airsacculitis after exposure to the virus.
Our findings indicated that the effectiveness of vitamin C was dose-dependent. We observed that adding between 300 to 330 parts per million (ppm) of ascorbic acid to their feed yielded the best protective results. Interestingly, when we looked at higher concentrations—beyond 600 ppm—the benefits seemed to diminish. This suggests that while vitamin C can be beneficial, there's a suitable range for its effectiveness.
Overall, this study highlights the potential of vitamin C as a useful dietary addition for enhancing the health of broilers facing bronchitis. Yet, it's clear that more isn't always better when it comes to dosage, and finding that sweet spot is crucial for maximizing its effectiveness.

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.

Antioxidants tested for heart attacks
In a recent clinical trial, we examined how a combination of antioxidants, including vitamin C, affects heart attack recovery. This study involved healthy participants who received either a blend of antioxidants or a placebo through an intravenous infusion. We measured the levels of vitamin C and other components in the blood, looking for signs of oxidative stress and monitoring any adverse effects.
Our findings showed that the antioxidant combination significantly increased vitamin concentrations compared to the placebo group. Moreover, we observed that this therapy seemed safe, with only mild, non-serious side effects reported in a small number of participants.
While antioxidants like vitamin C have been linked to health benefits, this study focused primarily on their safety and levels in the blood during a heart-related procedure. Although promising, we cannot definitively say that this approach improves outcomes for heart attack patients just yet. More research will be needed to explore its effectiveness further.

We observed an intriguing case involving a 4.5-year-old boy who developed significant knee pain due to a rare nutritional deficiency, scurvy. This condition stemmed from his exclusive intake of meat over the past two years, resulting in skeletal issues and inflammation in multiple joints, including his knees.
Upon examination, the child exhibited several symptoms, including pain, swelling, and an inability to walk. Standard blood tests primarily indicated anemia, but X-rays revealed alarming conditions related to scurvy, such as delayed bone age and severe osteopenia. This alarming picture led us to the conclusion that vitamin C deficiency was the underlying culprit behind his knee pain and skeletal issues.
After initiating vitamin C therapy, we noted a remarkable reduction in pain and swelling over the next two months. The child’s condition improved significantly, allowing him to walk again, and follow-up X-rays confirmed the positive changes in his bone health. This case clearly illustrates how vitamin C can effectively alleviate knee pain related to scurvy and reinforces the importance of proper nutrition for overall skeletal health.

We evaluated how vitamin C, also known as ascorbic acid, can help protect the liver during procedures that temporarily cut off blood flow—a process known as ischaemia followed by reperfusion. In this study, we used thirty-six male Wistar rats, split into control groups and experimental ones. Each group received the same total dose of vitamin C, administered at different times: either before the ischaemia, before the reperfusion, or both.
Our findings showed that the animals given vitamin C before both the ischaemia and reperfusion had improved outcomes. They had lower levels of liver enzymes, indicating less liver damage, and showed reduced inflammation. Additionally, their portal blood flow was better when compared to the other groups. Overall, our results suggest that administering vitamin C at specific times can significantly reduce liver injury associated with ischaemia-reperfusion.
This study highlights the potential of vitamin C as a protective agent in situations where liver damage is a concern during surgeries or treatments involving blood flow disruption.

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.

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.

I had a small basal cell carcinoma (BCC) on my face and recognised its symptoms from online images. I mixed Vitamin C crystals with water to create a paste and applied it with a Q-tip. This paste caused stinging on the cancerous growth, leaving healthy skin unaffected. After two weeks, the stinging stopped, and the tumour crusted over and fell off, revealing healthy skin beneath. I hope to never need this remedy again, though I have plenty left just in case.

Effectiveness of Vitamin C on Colds
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 ineffective against nausea
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.

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.

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.

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.

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 potential of sodium ascorbyl phosphate (SAP), a stable form of vitamin C, in preventing and treating acne vulgaris. The study included a time-kill analysis showing that a 1% SAP formulation reduced the harmful bacteria Propionibacterium acnes by a significant log reduction of 5 after 8 hours. This demonstrates the strong antimicrobial properties of SAP against acne-causing bacteria.
Additionally, we observed an in vivo study with 20 participants, where the SAP formulation effectively prevented up to 40% of UVA-induced sebum oxidation, suggesting it can help reduce inflammation associated with acne. In another open-label study involving 60 volunteers over 12 weeks, a 5% SAP lotion was rated as excellent or good in effectiveness by 76.9% of the participants, outperforming a commonly prescribed acne treatment.
Overall, our findings indicate that sodium ascorbyl phosphate could serve as an effective, non-antibiotic option for both the prevention and treatment of acne, making it an attractive addition to cosmetic products due to its lack of side effects.

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.

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.

We explored the effects of vitamin C on chest pain in chronic smokers experiencing endothelial dysfunction. In our study, 31 patients, who were undergoing diagnostic catheterization without significant coronary artery issues, participated in a controlled trial. They were given either an IV infusion of 3 grams of ascorbic acid (vitamin C) or a placebo saline solution before undergoing a cold pressor test to assess their coronary artery response.
The results were telling. Smokers typically showed a decrease in luminal area—an indicator of blood flow—during the cold pressor test. However, after infusing vitamin C, this response shifted positively, demonstrating improved blood flow through a vasodilation effect. On the other hand, those who received the placebo did not experience significant changes.
This means that for chronic smokers, acute administration of vitamin C appears to enhance the function of the endothelium, which is vital for proper blood vessel health and managing chest pain. Ultimately, we observed that vitamin C may help prevent the inactivation of nitric oxide, a compound that supports healthy blood flow, and this effect could be crucial for managing cardiovascular health in smokers.

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.

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.

Joint pain and stiffness have significantly reduced for both my dog and me. My 60-pound Border Collie has shown remarkable improvement in his joint stiffness and pain. I’ve continued with this form of vitamin C, which is effective for me, though I had to switch my dog to sodium ascorbate due to taste preferences.

We conducted a year-long study to investigate the effects of vitamin C on postoperative pain and recovery after a specific type of spine surgery known as posterior lumbar interbody fusion (PLIF). In this randomized, placebo-controlled trial, we worked with 123 patients, dividing them into two groups: one receiving vitamin C and the other a placebo.
Our main focus was to see how vitamin C influenced lower back pain measured by a visual analogue scale. While we found that there was no significant difference in pain levels at the one-year mark between the two groups, there was a silver lining. We observed that vitamin C appeared to enhance functional improvement, especially within the first three months after surgery.
So, while vitamin C didn’t seem to directly reduce pain intensity after surgery, it could play a role in supporting early recovery and everyday function. This finding may encourage further exploration into vitamin C's potential benefits in postoperative care for patients undergoing spine surgeries.

Great for everyday use, especially during colds and flu! I gave this to my mum when she started feeling ill. Within two days of taking these crystals, she was back on her feet, avoiding doctor visits and infections. Impressive!
