Ester C may reduce cold frequency
We conducted a study involving 168 volunteers who were given either a placebo or a vitamin C supplement for 60 days during the cold season. Participants recorded their cold symptoms in a diary, and those on the vitamin C showed promising results.

The groups taking the active treatment reported significantly fewer colds and experienced fewer days of viral illness. Additionally, their severe symptoms lasted less time than those in the placebo group. Most volunteers experienced few side effects and enjoyed using the supplement, finding it more effective than prior vitamin C forms.

Overall, this vitamin C supplement could help prevent colds and ease symptoms, offering hope for better winter health.

Strengthens immunity

I bought these vitamins for my daughter, and despite the capsule size, she finds them easy to swallow. This is a repeat purchase as they effectively help with common colds. The Ester-C formula provides 1000mg of vitamin C, alongside other immunity boosters like vitamins A, D3, B-6, B-9, and B-12. The combination of ingredients also includes elderberry and echinacea, making it a great option for preventing colds. I give my child one capsule daily, while I take two for overall health.

Supports immunity
A good quality supplement to support immunity during common colds. I only take Vitamin C in the form of ESTER C to avoid stomach issues. This was my first order from this manufacturer, and I'm pleased with the balanced composition. Given that Ester C from other brands has been out of stock, I'll definitely order more despite the price. Thank you to everyone who enjoys this product!

Cold remedy
I really like the ingredients in this product; they work well as a remedy for common colds. Although I'm not keen on the rice bran oil included, I have managed to avoid falling ill by taking this product regularly.

Good composition
I have purchased other vitamins by the same manufacturer and enjoyed them. These were cold teas, but I wanted to try the vitamins due to their excellent composition. I appreciate the quality, but I must mention that the capsules are quite large, making them uncomfortable to swallow, and there is a slight smell. Nonetheless, I hope they effectively help with common colds.
