In this week’s episode, Dr. David Sinclair and co-host Matthew LaPlante zero in on drugs and supplements that have been reported to combat aspects of aging. They share the latest experimental and clinical data for NAD boosters, resveratrol, fisetin, quercetin, rapamycin, spermidine, metformin, and berberine. Given the abundance of data available, a special focus is placed on the NAD precursors nicotinamide riboside and nicotinamide mononucleotide. Known mechanisms, limitations, and/or side effects associated with these molecules are additionally highlighted. Correction and clarification: At time point 1:07:37, Dr. Sinclair says he takes 1 gram of Spermidine, but the active ingredient in the capsules is 1-2 milligrams. We apologize for the confusion.
