Pure Fisetin

Key Benefits

• Provides 250 mg fisetin per capsule.

• Sourced from Rhus succedanea extract.

• Delivers a concentrated plant flavonoid.

Pure Fisetin delivers a concentrated 250 mg dose of fisetin in each capsule, sourced from Rhus succedanea stem extract. Fisetin is a naturally occurring flavonoid found in small amounts in foods such as strawberries, apples, and grapes.

This formulation focuses on a single active ingredient, offering a consistent and measured intake in every serving. It includes vegetable cellulose and microcrystalline cellulose to form the capsule, keeping the composition simple and straightforward.

Designed for those looking to include fisetin as part of their routine, this supplement provides a convenient way to achieve a higher intake than diet alone.

Pure Fisetin focuses on controlled production and verified quality. Each batch undergoes three rounds of independent third-party laboratory testing to confirm potency and purity before release. Manufacturing takes place in FDA-regulated, GMP-certified facilities in the United States, where strict quality and safety standards guide every stage of production. This structured testing and manufacturing process gives you a fisetin supplement developed with consistency and transparency at its core.
