From BioPharma Scientific. I won’t use it while I’m doing a Whole30, but when I’m not… This is the only multiminerals supplement I can see myself using for a while. It’s difficult to make certain that I get all of the minerals that I need, and most supplements have an issue with bioavailability. Chelation mostly solves that, but the best brand (Albion) makes pills which are EXTREMELY difficult for me to swallow. Enter the only chelated multi-mineral powder on the market: NanoMineral.
