What it is
Dimethylated analogue of resveratrol from blueberries and red grapes; dimethylation substantially increases lipophilicity, improving cell membrane permeability and metabolic stability compared with resveratrol; SIRT1 activator, NF-κB and AP-1 inhibitor; stronger tyrosinase inhibition than resveratrol in cell-free assays; greater oxidative stability in formulation than trans-resveratrol; used as a more bioavailable resveratrol alternative in antioxidant serums; topical clinical data is limited but increasing.
