Anti-aging products from skin creams to chemical peels are part of a $250 billion industry, but scientists have yet to discover a longevity elixir that stands up to medical scrutiny.
Sinclair's lab researchers believe they’re getting closer, however, thanks to a compound called nicotinamide adenine dinucleotide, or NAD+ for short.
But another company, called Elysium Health, is already selling a supplement called Basis that contains compounds known to boost NAD+ levels. (Basis is the supplement tested in the 2017 Nature study.) Leonard Guarente, Elysium’s chief scientist and co-founder–who also directs the Glenn Center for Biology of Aging Research at MIT–says Basis is not intended to extend people’s life spans, but to help them stay healthier for longer. Eight Nobel laureates are on the Elysium company’s scientific advisory board
