We investigated whether a daily vitamin C supplement could reduce the risk of catching colds. Over two months, 168 people took either the supplement or a placebo. Results showed that those taking vitamin C experienced significantly fewer colds and shorter durations of severe symptoms compared to the placebo group.
This supplement was well-tolerated with minimal side effects, and participants were notably satisfied with it. Overall, it seems that vitamin C may not only help prevent colds but also assist in faster recovery from them.

Vitamin C alleviates cold symptoms
We looked into how vitamin C affects cold symptoms through a well-structured study involving 622 volunteers divided into treatment groups. They received either vitamin C or a placebo over a 15-week period.
While both vitamin C groups experienced milder illnesses compared to the placebo group, there were no significant differences between the two forms of vitamin C used. Interestingly, those taking vitamin C spent about 25% fewer days sick indoors. This suggests that while vitamin C can alleviate some cold symptoms, we might not need as high a dose as previously thought.

These are fantastic for my immune system! I’ve taken them for nearly two years, during which I’ve had no colds despite having COPD and rheumatoid arthritis. I highly recommend this as the best supplement I've ever taken for my immune health.

Works Great. I always begin taking these at the first sign of cold symptoms. They often eliminate the cold before it takes hold but consistently shorten its duration when it does.

Natural antibiotic alternative
1 people found this helpful
Natural ingredients helped shorten my cold and allowed me to avoid antibiotics! The quality is excellent, as I take one every few hours. The tablet size is manageable and does not upset my stomach acidity. It serves well as an antioxidant and immunity support. My only complaint is that it ran out quickly... but I had it at a 50% discount.

Preventive measure

This esterified vitamin C, combined with vitamin D, A, and zinc, along with echinacea and elderberry, provides complete protection. When I had a diagnosis, I relied on vitamin C and other ingredients, which made me feel more at ease. I woke up with just a slight sore throat, a testament to this product's preventive qualities against colds.
