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

Vitamin C is one of the highest cost ratio and beneficop, because the action of antioxidant and diuretica are incredible. Is supporting me 100% in the cutting phase. more dislocated parabens for 21st Century
The price is the best.
