Elysium, a company founded by an M.I.T. biologist, and backed by Nobel Prize-winners, has begun selling a dietary pill called Basis, which combats the effects of aging.
The product, a blue capsule, isn’t a drug. It has among other ingredients, a chemical precursor to a critical compound found in all living cells, known as NAD+ (short for nicotinamide adenine dinucleotide.)
With age, NAD+ levels decline. Basis will work by supplying the body with the building blocks needed to synthesize its own NAD+, and retard the speed of senescence.
