Effectiveness of Vitamin C on Colds
Vitamin C for the common cold and pneumonia.
Strong relevance to cold prevention
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 improves cold tolerance
Application of Exogenous Ascorbic Acid Enhances Cold Tolerance in Tomato Seedlings through Molecular and Physiological Responses.
Directly addresses cold tolerance
We explored the effects of ascorbic acid, commonly known as vitamin C, on cold tolerance in tomato seedlings. In our study, we discovered that applying vitamin C significantly boosts the seedlings' ability to handle cold stress.

By enhancing the antioxidant defense system, vitamin C treatment increased the enzyme activity in the seedlings' leaves. Additionally, it raised levels of important compounds such as proline, sugar, and abscisic acid, all of which play crucial roles in plant stress responses.

Our observations showed that vitamin C also protects the photosynthesis system of tomato seedlings. This implies that it helps maintain chlorophyll function, which is critical for the plant's overall health, especially under cold conditions.

Moreover, we found that vitamin C treatments led to increased expression of genes linked to antioxidant enzymes and cold response mechanisms. Overall, our findings suggest that exogenous vitamin C is a beneficial approach to improve cold tolerance in tomatoes and may provide helpful insights for farmers looking to cultivate hardier varieties during colder months.

Immune support boost
Take it, you won't regret it! This excellent quality vitamin has a sustained release, with half absorbed immediately and half entering the body over 12 hours. One capsule per day is standard, but during colds, you can take up to six capsules daily for the first few days to enhance immunity. Symptoms improve quickly, and I felt better by the second day without severe illness. It’s non-allergenic, which is a relief for someone like me who previously reacted to Russian vitamin C. This option is also significantly cheaper than what’s available locally. Please click "thumb up" if you find this useful!

Cold symptoms relief
After catching a cold, I took two pills for three days, which helped alleviate the cold symptoms. The only downside is the pill size, but the quality is commendable.

No colds observed
I take one capsule after breakfast and dinner. While there are tablets, the capsules are easier to swallow, which I prefer. Vitamin C typically gets excreted quickly, but this product is remarkable in its continuous absorption and efficacy! I've been using it for over a year now and haven't caught a cold in that time.

Reduces fever quickly
I usually take 1 tablet three times daily. When I have a high fever, 38-39 degrees due to a cold, taking 1-2 tablets every 5-30 minutes reduces the fever within 3-4 hours. If I take them when feeling cold chills, the chills subside after a few hours and my fever decreases. However, I must be careful as continuous intake can upset my stomach.

Very effective against cold
I’ve observed that I do not catch a cold when I take this. I have tried various brands of vitamin C, but this one feels the most effective.
