Fisetin

Fisetin is a flavonoid found in strawberries and other fruits. It's being researched as a powerful senolytic—a compound that clears senescent 'zombie' cells linked to aging and disease.

Research Level: Promising but limited human data

Dosage

100-500mg daily for general use; higher doses (1-2g) intermittently for senolytic effects

When to Take

For senolytic effects, some protocols use high doses for 2-3 consecutive days monthly.

Benefits

  • Potent senolytic activity
  • Clears damaged senescent cells
  • Anti-inflammatory properties
  • Neuroprotective effects
  • May support memory and cognition
  • Antioxidant protection

How It Works

Fisetin selectively induces apoptosis (programmed death) in senescent cells while sparing healthy cells. Senescent cells accumulate with age and secrete inflammatory compounds that damage surrounding tissue.

Possible Side Effects

  • Generally well-tolerated
  • Limited human safety data at high doses
  • Possible GI upset

Drug Interactions

  • May enhance effects of chemotherapy (consult oncologist)
  • Theoretical interaction with blood thinners

What to Look For

  • High-purity fisetin (98%+)
  • Third-party tested
  • Liposomal form for better absorption
