This is very good vitamin C product!

Posted by iHerb Customer on Jun 02, 2010 | Verified Purchase

There is only one that I prefer more, but unfortunately i-herb does not carry that one, except in powder (Twinlab, multiascorbates).

Thanks for your feedback!

I've been using this for years and find my body likes it better than any other vitamin C product.

Thanks for your feedback!

The best Vit C

Posted by petitecoton on Oct 04, 2015 | Verified Purchase

I take 2 capsules per day, morning and night. I think 500mg is effective for absorption. My skin look brighter and I never got sick after I took this Vit C formula.

Thanks for your feedback!

Seems to be a good product.

Works Great and Great Deal

This is th best brand of Ester-C I have found. And is comes in a capsule form that's easy to swallow versus MOST that come in rock hard, odd-saped tablets. 5 Stars!

Thanks for your feedback!

Easy on the stomach

I always use Ester-C because it's easier on your stomach and more asorbable.

Thanks for your feedback!
