GNC (and likely other online supplement stores) have an online presence and likely has some QA for the products they sell. Amazon just insists on having 1,000,000+ listings for supplements rather than a more curated list. Perhaps some categories shouldn't have endless list of products.
- lotsofpulp 3y agoThe only QA in the "supplement" and "vitamin" business I know of is USP: https://www.quality-supplements.org https://www.quality-supplements.org Although, I have no clue if USP simply rubber stamps it once time, or if they do continuous testing of the products. If I were to bet, I would say they probably do not test often enough after initial certification.
