Great
I’ve been using American Health Ester-C 500 mg for a few weeks and I’m very satisfied with the results. The capsules are easy to swallow and gentle on my stomach compared to regular vitamin C supplements. I take them daily to support my immune system and overall energy levels. The bottle lasts a long time with 120 capsules, which makes it a great value for the price. I also like that Ester-C stays in the body longer than standard vitamin C. Highly recommended for anyone looking for a reliable daily vitamin C supplement.

Ester-C is very easy to use, it has a pleasant taste and works fast. It gives an istant reliefe when you feel down. I use it with the first signs of cold or flu and repeat several times with intervals of an hour or two and it helps to avoid the sickness. It doesn't affect the stomach and absorbs very quickly.

This is a good product!
Ester-C is supposed to make digestion of Vitamin C, easier. This one has only Ester-C in it, and no other additions. Simple and effective!

Best brand and great vitamin C!
We always have this product at home, especially during cold season. If I feel like I’m coming down with a cold, I double the dose, and it really helps me feel better quickly. It’s become a staple for keeping my immune system strong.

No Rose Hips!
Pretty much straight “C” with added calcium. We have opened a capsule and put it in our dog's food for joint health and to boost the immune system.
