the best

Posted by iHerb Customer on Oct 08, 2015 | Verified Purchase

My doctor told that I have to take 4gr. of vit C every day. 'Metabolic maintenance' does not have any junk in them capsules plus that vit.C very jentle on your tommy, I even can take it with no food. For 5 years I did buy it from company and was so happy when iherb start to carry it because iherb much much better in shipping than manufactor. I taste lot of C. and this one the best and it works,no my husband or I ever get sick, since we take it, plus much younger looking, but we have it every single day for 7 years. love it, hope iherb will carry it always
