Perspectives as Charles Brenner challenges David Sinclair on longevity claims

This is a debate about whether popular claims for extending human life are supported by good evidence. It discusses boosting NAD, nicotinamide adenine dinucleotide, a molecule cells use to produce energy. The evidence includes animal studies, laboratory work, and limited human research, not one large, conclusive trial. Some findings look promising, while other experts say the benefits have been overstated.

What this means for you: Do not buy a longevity supplement based on these claims alone. The evidence is still too uncertain to show that these products help healthy people live longer.
