What We Like

  • Very affordable per daily serving
  • Vegan capsules and low-allergen formula
  • Readily available within the EU supply chain

What We’re Missing

  • No purity percentage or bioavailability data disclosed
  • Fisetin is light- and heat-sensitive; store in a cool, dark place

Usage Recommendation

1–2 capsules with a fatty meal. For senolytic protocols, commonly used for 3–4 consecutive days followed by a break.

Ingredient dossier
