In a 90-day human study, more hair in its growth phase.

In the study, 100 men and women took a spermidine supplement or a placebo every day, and nobody knew who was getting which.

On spermidine, hairs in full growth went from 25 to 37 per 100. On the placebo, they fell from 26 to 20.

That's autophagy at work, the deep cellular renewal your body does less of every year. Spermidine is what switches autophagy back on.

You'll usually see it in your hair first, at around 90 days. The same process that grows hair back makes nails stronger and skin firmer.

Fuller hair. Stronger nails. Firmer skin. One molecule behind all of it.

And spermidine is linked to nearly 6 years of longer life.
