Frequently Asked Questions

Q: Does fisetin powder mix well?

A: Pure fisetin powder has low water solubility and may not mix easily in cold beverages. For better results, mix it with a small amount of warm liquid first, or use a liquid containing healthy fats (like nut milk or olive oil) as fisetin is fat-soluble. Using an electric mixer or blender can also significantly improve mixing.

Q: What is the best form of fisetin to take?

A: The most effective form is a high-purity, micronized fisetin powder in a lipid-based formulation (such as softgels or in an oil base). This enhances its absorption, as fisetin is fat-soluble. Always choose supplements from reputable manufacturers that provide verified purity certificates (COA).

Q: How long should you take fisetin?

A: Common usage involves cyclical approaches, such as taking it for 2-3 consecutive days per month, due to research focusing on periodic, high-dose “senolytic” protocols. For daily general antioxidant support, lower doses may be used. We strongly recommend consulting a healthcare professional for a personalized dosage and cycling plan.

Q: Does fisetin really work?

A: Current scientific evidence, primarily from preclinical studies, is very promising. Fisetin demonstrates potent senolytic activity (helping to clear aged, dysfunctional “senescent” cells) and strong antioxidant and anti-inflammatory effects. While more human clinical trials are ongoing, existing data supports its potential for promoting cellular health and healthy aging. Individual results can vary.
