iHerb Customer Reviews

Good but not sure about sufficient vit C content

Posted by 5059305835663687659 on Jun 19, 2016

It is not upsetting on the stomach, but I got some cold while taking it even though it should contain 1.000 mg of vitamin C in each tablet. When I started taking 500 mg more from Country0s life, I got better in one day. So I am not sure about the vitamin C content. B complex seems to be working fine and yellow pee color is probably the sign to have it enough.

Not sure of ....

Posted by 4685375285003645141 on Aug 26, 2012

I do not recommend this product due to the fact that something in it is not agreeable to me. But someone else who is not highly sensitive may be able to take it. iherb does have some other great products, this one not so great.
