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 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.

Vitamin C has helped me tackle two issues. Initially, I took it alongside folate for better absorption. At the first sign of a cold sore, I took two, and the symptoms vanished by the next day. I was amazed! Additionally, my acne cleared up considerably after starting these vitamins. My skin is combination and I'm 32, but traditional treatments weren't effective. However, these vitamins made a noticeable difference. Now that I've finished them, my skin has flared up again. I plan to order more to boost my immune system while addressing the root cause of my acne.

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.

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 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.

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.

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 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 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.

Improved migraines
Most Useful Review
Taking two capsules regularly normalises my sleep and reduces my migraines significantly. Whenever I feel the onset of a migraine, I take the pills along with additional magnesium, and it subsides within a few hours—previously, I would be incapacitated for half a day. I've also noticed a decrease in migraine frequency, possibly aided by my other medications. Consuming magnesium regularly eases PMS symptoms, and I don't experience the negative mood swings I used to. While it's challenging to attribute chronic pain relief to magnesium alone, as I take other supplements too, I believe it has had a considerable positive impact on my overall health. The product is effective, made from natural ingredients, and offers no adverse reactions.

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 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 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.

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 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 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.

In my opinion, Solgar produces the best vitamin C among others; they are the finest company for vitamins and dietary supplements. The quality of their vitamin C is exceptional, truly invigorating and very effective for ARVI (I find it almost irreplaceable). It does not encourage the formation of kidney stones, which can occur with vitamin C ascorbate (I can confirm this as I have regular ultrasound scans and take vitamin C daily). It does not irritate the gastrointestinal tract; however, those with gastritis and urolithiasis should consider Ester-C from the same brand. I highly recommend it.
