Kwon JH, Kim D, Cho H, Shin BS. Ascorbic acid improves thrombotic function of platelets during living donor liver transplantation by modulating the function of the E3 ubiquitin ligases c-Cbl and Cbl-b. J Int Med Res. 2019;47:1856. doi:10.1177/0300060518817408

We sought to understand how ascorbic acid, commonly known as vitamin C, impacts blood clotting during living donor liver transplantation (LDLT). In our study, we analyzed blood samples from 21 recipients before and after their surgeries.

We employed a well-structured approach, using rotational thromboelastography (TEG) and western blot analysis to scrutinize fibrinolysis and the functionality of specific proteins involved in clotting. Blood samples were tested in three distinct groups, one receiving vitamin C, to see its effects on clot rigidity and fibrinolysis.

Our findings revealed that ascorbic acid notably reduced fibrinolysis, which refers to the breakdown of blood clots, and improved the rigidity of the clots formed. Additionally, we observed that levels of a protein called Cbl-b were higher in those receiving vitamin C, while another protein, c-Cbl, showed reduced phosphorylation. These functional changes might explain how vitamin C supports better clotting during surgeries.

This study indicates that vitamin C could be a beneficial treatment to consider during LDLT to manage hyperfibrinolysis, thus promoting better outcomes for patients undergoing these complex procedures.

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.

Noordin S, Baloch N, Salat MS, Rashid Memon A, Ahmad T. Skeletal manifestations of scurvy: a case report from dubai. Case Rep Orthop. 2012;2012:624628. doi:10.1155/2012/624628

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 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.

Hammar M, Berg G, Solheim F, Larsson L. Calcium and magnesium status in pregnant women. A comparison between treatment with calcium and vitamin C in pregnant women with leg cramps. Int J Vitam Nutr Res. 1987;57:179.

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.

Haile A, Mara S, Belete Y, Dejene T. The Forgotten Disease in the 21st Century: Scurvy Outbreak in Hawassa Central Prison, Hawassa, Sidama, Southern Ethiopia, 2023. Int Med Case Rep J. 2023;16:847. doi:10.2147/IMCRJ.S438833

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 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.

We explored the effects of ascorbic acid and its derivatives on the replication of Herpes simplex virus type I using human muscle cancer cells.

The study revealed that a specific form of vitamin C, known as 2-O-glycoside of ascorbic acid, showed promising antiviral properties.

Interestingly, while this derivative can inhibit certain chemical reactions involving carbon-centered radicals, it does not impact reactions with oxygen-centered radicals.

However, despite these findings, the overall benefits of vitamin C treatment for herpes remain inconclusive.

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.

Kodama M, Kodama T. The clinical course of interstitial pneumonia alias chronic fatigue syndrome under the control of megadose vitamin C infusion system with dehydroepiandrosterone-cortisol annex. Int J Mol Med. 2005;15:109.

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.

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.

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.

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 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 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 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 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.

Zhao D, Long X, Wang J. Association between dietary vitamin C intake and migraine in adults: A cross-sectional study of the National Health and Nutrition Examination Survey. J Hum Nutr Diet. 2024;37:1454. doi:10.1111/jhn.13366

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.

This super vitamin allows me to remain well through winter. If I feel itching or discomfort, I take a double dose and the ailment vanishes. I've noticed that my headaches dissipate after taking it. It's a product I intend to use indefinitely!
