Effectiveness of Vitamin C on Colds
Vitamin C for the common cold and pneumonia.
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.

Excellent vitamins! We have been taking them for several years during cold and flu season. At the first signs of illness or exposure to someone unwell, we start taking this vitamin C, and all symptoms vanish by day two! It’s a fantastic product that I always keep in my first aid kit and share with friends and family, who are all very pleased. My daughter adores the raspberry flavour, while my son and husband prefer orange and tangerine. There’s something for everyone! I highly recommend it as a favourite from Ayherb!
