Ester C

Posted by Reviewer3018804 on Jun 03, 2016

I had the 1,000 mg tablet form first, but found them too big. The 500 mg veggie cap is much easier to swallow. Good product, I read it is recommended for people with adrenal issues.

small reaction to the bioflavanoids

Posted by 5699993330116946412 on Oct 26, 2012

i have peripheral neuropathy and these consistently caused a mild tingling sensation for about 45 minutes. i finished the bottle then tried the ester c without the added bioflavanoids and had no reaction. these are likely great for most people but someone that is very sensitive may do better on the straight ester c that iherb also sells.

Great Immune System Support!

Posted by Reviewer2947738 on Aug 29, 2012

I've been taking this brand for a long time now. It's easy on my stomach and it really boosts my immune system! If I feel slightly under the weather, I take up to 7,000 mg a day! It really works! Love it!

I have been using this for a long time

Posted by Reviewer2582051 on Aug 08, 2012

I don't know if this is the best vitamin C product out there, but I have used it for a long time. I don't get an acid stomach with this one.
