good value for money

Posted by adhd-researcher on Jun 26, 2016

you cannot absorb more than 500 mg every few hours so all the brands with 1000 mg, is that just to induce diarrhea when you are constipated ? you know: 1 gram every 15 min till you have loose stools and if you count all the grams of vit C you took until your "explosion", that is the limit of vit C you need per day it is cheap and in the "Ascorbic Acid" form, so NOT REAL VITAMINE C better take ascorbate, but even NOW FOOD , don't specify it is NON GMO sourced and many products are manufactured in CHINA have to read the small labels to find this out
