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.

Great for colds! I always keep a jar during the autumn-winter months, as a higher dosage can stop ARVI at the initial stage and facilitate recovery.

Immunity support
Vitamin C supports immunity, helping me avoid getting sick. When I have the first signs of a cold, I take a capsule with zinc or elderberry, and usually, it works well. This supplement has been effective and gentle on my stomach, making it suitable even for long-term use. I find it beneficial for blood vessel health too.

No colds for years
Great product: Best Vitamin C Capsules. I’ve been taking Solgar Vitamin C 1000 mg for several years, and find them to be an effective antioxidant. I haven't experienced a cold or flu in years, since taking one capsule daily.

Consistent effectiveness
It seems to work for me. Just like the picture, I take it often and have not experienced flu or cold. I typically mix the powder with water, as it is quite acidic.
