INSIGHTS B — STAGING

There's a molecule in your body right now that's quietly determining how fast you age. It's called NAD+ — nicotinamide adenine dinucleotide — and you're losing it. Steadily. Relentlessly. By the time you're 60, you'll have half the NAD+ you had at 40. And that loss is connected to almost every hallmark of aging science has identified. The good news? We might be able to put it back.
