Effectiveness of Vitamin C on Colds
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
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.

Miracle cold pill

These really do work! They are my go-to whenever I feel unwell. They taste good and are more convenient than mixing the powdered version. I refer to them as my cold season miracle pill because they genuinely help! I share them with family and friends, and everyone agrees they expedite feeling better.

Really works! These chewables are the best! I used to catch colds all the time, which lasted for weeks. Now, if I feel I might be getting sick, I pop a couple of these chewables and they seem to prevent the cold from worsening!

Fewer colds noticed

The taste isn't bad. I take one every day. While I am sceptical, I have been healthier than ever, particularly with regard to colds. I am getting fewer colds and sinus infections. I take one daily, or two if I'm not feeling great or if my child is unwell.

Effective for allergies
2 people found this helpful
This vitamin C product has a slight tartness but is far preferable to immune vitamins that require drinking. They are chewable; while I'd like them a bit smaller, they do the job. Whenever I have allergies, cold, or sinus issues, I take two per day and feel better. I've been taking them daily since Covid-19 to boost my immune system, and honestly, I feel good with them.

These tasty wafer vitamin C chews are not too sweet or tart, and they contain a great amount of Vit C, 1,000 mg, in a nice chewable form. I believe they have helped us this year with colds and respiratory issues. Despite illness in the family, taking these for our immune system has been beneficial, and I would recommend them.
