Product is great for me who has gastritis.

Posted by 4657173603185088080 on Dec 20, 2016

Compared to the capsule form, this is less expensive and has no acid. So it fits me perfectly since most Vit C is acidic in form.

More bioavailable; harder to swallow

Posted by 5559590992830793214 on Oct 06, 2016

My clinical nutritionist had me switch over to this product as it's more bio-available and has less "fillers" (of dubious origin) than the powdered Vitamin C I was on before. I know (from my Doc) that this is an overall better product, however, to me it has a kind of "farm yard" smell (maybe that's just my pregnancy making my sense of smell weird!) that makes it a little harder to swallow. But otherwise very happy with it!

Ester-C with citrus bioflavonoids 240 capsules

Posted by Reviewer2320947 on Jun 14, 2016

I like the Ester=C with citrus bioflavonoids 500 mg, and take it in three separate doses a day. I also prefer it in capsules. These were recommended by my Naturopath.
