Spermidine

Spermidine is a naturally occurring polyamine that induces autophagy—your body's cellular cleanup process. It's found in aged cheese, wheat germ, and other foods, and is emerging as a longevity supplement.

Research Level: Promising but limited human data

Dosage

1-6mg daily; higher doses in studies

When to Take

Can be taken any time. Some prefer morning.

Benefits

  • Induces autophagy (cellular cleanup)
  • May slow aging processes
  • Supports cardiovascular health
  • May improve cognitive function
  • Supports healthy hair growth
  • May enhance immune function

How It Works

Spermidine triggers autophagy, the process by which cells break down and recycle damaged components. This 'cellular housekeeping' is crucial for healthy aging and declines as we age.
