Glutathione interacts with certain medications and other supplements, and there is limited scientific data on these interactions, so caution and consultation with a healthcare provider is advised
Rhonda Patrick: And then because I'm competitive during the recovery that they give you at the minute, at the end, I'm pushing at max, so the number's higher
Aggregation becomes more pronounced for ultrasmall Pt nanoparticles due to high surface energy, which can drastically reduce accessible active sites and mimic low activity
I thought it was gonna help me lose weight like Ozempic but I guess not I give it a 3 because in someway it did control a bit of my appetite but just that
