Any company that is selling a supplement with resveratrol is not worth dealing with. Resveratrol serves absolutely no function - none.
As for UA/Mitopure, it is very expensive. I don’t know what group paid for this latest study. On expense alone I won’t take it. I did buy some 3-4 years ago when it first was coming out. Nestle and L’Oreal are investor/owners of Mitopure
