iHerb Customer Reviews

Well tolerated

Posted by 5608900336638002819 on Dec 02, 2016

I am actively working to improve my immune system and Vitamin C is key in that effort. This formula is well-tolerated and seems to be truly sustained release as there does not seem to be signs of it being eliminated from the body in large amounts. Sorry if that is TMI, but there isn't really any other way to tell that I know. So far have been feeling better overall.

Also has generous amount of bioflavs Non GMO

Posted by Reviewer2631717 on Mar 02, 2016

This is reasonably priced. I choose it because I save money not buying extra bioflavs - and one less pill to pop. And the bioflavenoids do keep my gums from swelling. I was concerned about GMO's. so asked Now Foods. Now told me that this is made from non-gmo corn in China. And that every batch is tested. Since the price has been steadily rising from my first bottle $16 to over $19, I have been looking for an alternative. I tried the cheaper Jarrow brand with 500mg of C and 250mg bioflavenoids. They also work well, but one drawback is that Jarrow doesn't have any Rutin included.

Not really buffered C

Posted by 5573606424698072913 on Feb 28, 2016

Not really buffered C as it still taste sour. Difficult to swallow as the tablet is too big!
