Senolytic Activator
Life Extension offers the best value-to-science ratio by using Bio-Fisetin, which is formulated with galactomannans from fenugreek seeds to increase bioavailability by 25 times over standard fisetin.
Ingredients & Purity
Features Bio-Fisetin, Quercetin Phytosome (bioavailable form), and Apigenin to support the destruction of 'zombie cells'.
Scientific Evidence
Life Extension is a leader in longevity research; they use the Indena Phytosome technology which has extensive clinical backing for absorption.
Brand Transparency
Clear labeling of standardized extracts; however, specific batch COAs are usually available only upon request rather than listed on the product page.
Value Assessment
At roughly $20 for a 12-serving supply (intended for once-weekly use), this is the most accessible entry point into high-quality senolytics.
Why Not Alternatives?
Standard fisetin is notoriously difficult for the body to absorb. This product solves the bioavailability issue at a fraction of the price of boutique longevity brands.
