Vitamin C lessens oxidative stress

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 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.

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.

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 for knee pain relief

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.

I continually order this for my mother, who is over fifty. She has noticed a reduction in her knee pain.

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 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 aids chloride transport

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 may reduce breast cancer

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.

Allergies details

Pleuran and Vitamin C aid asthma

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 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.

Effectiveness of Vitamin C on Colds

Hemilä H, Chalker E. Vitamin C for the common cold and pneumonia. Pol Arch Intern Med. 2025;135. doi:10.20452/pamw.16926

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 mitigates flu pneumonia

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.

Likely Very Effective

Vitamin C enhances immune response

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.

Based on 5 Researches

Vitamin C aids immune function

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.

Vitamin C reduces cold severity

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 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 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.

Vitamin C aids omeprazole therapy

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.

Based on 3 Researches

Ascorbic Acid and Dizziness Study

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.

In our recent study, we set out to explore the effectiveness of a 5% sodium L-ascorbyl-2-phosphate lotion, a stable form of vitamin C, for treating acne. We conducted a double-blind, controlled trial with 50 participants over 12 weeks, where half used the vitamin C lotion and the other half received a placebo.

Our findings revealed significant improvements in acne symptoms for those using the vitamin C lotion compared to the placebo group. We measured outcomes through various assessments, including a global evaluation by investigators and self-reported assessments by the subjects, along with lesion counts.

The results showed that the vitamin C lotion was not only effective but also well-tolerated, with side effects similar to those seen with the placebo. This adds a promising tool to the options available for acne treatment, suggesting that vitamin C might play a valuable role in skincare regimens aimed at combating acne.

Overall, our study supports the idea that vitamin C, in the form of sodium L-ascorbyl-2-phosphate, can help reduce acne, making it a noteworthy addition to acne treatment strategies.

Diarrhea details

Vitamin C improves diarrheic calf health

Zakariya MR, Ghasemi E, Hashemzadeh F, Ghorbani GR, Ahmadi F. Does vitamin C supplementation in milk improve growth and health of diarrheic calves?. Prev Vet Med. 2024;224:106122. doi:10.1016/j.prevetmed.2024.106122

We investigated how adding vitamin C to milk influences the growth and health of young calves, particularly those experiencing diarrhea. The study involved 48 Holstein calves, which were sorted into two groups based on their health status: healthy calves and those with diarrhea. Each calf was fed the same amount of pasteurized milk and monitored until they reached 74 days of age.

Calves that received vitamin C showed an impressive increase in weight by weaning—74.3 kg compared to 72.2 kg for those without vitamin C. Additionally, calves treated with vitamin C demonstrated improved blood antioxidant levels, suggesting better overall health. Notably, calves suffering from diarrhea benefitted significantly from the vitamin C, needing fewer days of medication for treatment compared to those who did not receive the supplement.

The research highlights that vitamin C can play a critical role in supporting the health of calves during episodes of diarrhea. This is especially relevant for those that faced even mild cases early in life, as they seemed to gain the most benefits from the supplementation. Overall, it appears that vitamin C can positively impact both growth and health in calves suffering from diarrhea.

Based on 4 Researches

Vitamin C's limited impact on pain

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.

Vitamin C improves coronary response

Based on 13 Researches

Schindler TH, Magosaki N, Jeserich M, Olschewski M, Nitzsche E, et al. Effect of ascorbic acid on endothelial dysfunction of epicardial coronary arteries in chronic smokers assessed by cold pressor testing. Cardiology. 2000;94:239.

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.

Vitamin C intake risks explored

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.

We explored whether high-dose vitamin C could help reduce pancreatic necrosis in cases of severe acute pancreatitis (SAP). Our observations reveal that platelet activation early in pancreatitis is a critical factor leading to pancreatic tissue death.

In our study, we examined the effects of high-dose vitamin C on pancreatic microcirculation in rats. We analyzed platelet activity in both SAP rats treated with vitamin C and those untreated. Additionally, we evaluated how vitamin C affects platelets from SAP patients.

To understand the mechanism at play, we used substances that could counteract vitamin C's effects, helping us pinpoint its role in platelet activation. The results indicated that vitamin C significantly improves blood flow and reduces pancreatic damage by inhibiting platelet activation, specifically through the CXCL12/CXCR4 pathway.

This research suggests that high-dose vitamin C could serve as a beneficial treatment for pancreatitis, potentially improving patient outcomes by tackling a major cause of pancreatic necrosis.

Vitamin C's impact on bloating

Zeitoun T, El-Sohemy A. Associations Between Dietary Vitamin C, Serum Ascorbic Acid, and Genotype and Premenstrual Symptoms. J Am Nutr Assoc. 2023;42:525. doi:10.1080/27697061.2023.2186963

We aimed to explore how different measures of vitamin C might influence premenstrual symptoms, particularly bloating. In this study, we analyzed data from 555 women aged 20 to 29 years who reported on various symptoms associated with their menstrual cycles. We looked at their dietary intake of vitamin C, measured serum ascorbic acid levels, and assessed genetic factors through DNA testing.

Our findings suggest that higher vitamin C status is linked to increased appetite changes and symptoms like bloating and swelling during the premenstrual phase. While we observed associations between vitamin C levels and these symptoms, it's important to note that our study didn't isolate the effect of vitamin C from other dietary influences. Therefore, while there's a connection between vitamin C and bloating, we cannot conclusively say that vitamin C alone is definitive in relief.

Overall, this research opens the door to understanding how nutrition, particularly vitamin C intake, may shape our experiences with premenstrual symptoms. However, it also highlights the complexity of diet's role in our health.
