Quercetin Phytosome
Thorne is the gold standard for clinical purity. Their Quercetin Phytosome uses the Indena Quercefit delivery system, which is proven to be up to 20 times more bioavailable than standard quercetin.
Quality & Materials
Uses Quercefit (Quercetin phospholipid complex). This form is specifically designed to cross the lipid membrane of the gut.
Evidence & Testing
Quercetin is one half of the famous 'D+Q' (Dasatinib + Quercetin) senolytic cocktail. Thorne is frequently used in clinical trials due to its manufacturing standards.
Brand Transparency
Highest level of transparency in the industry. Thorne owns its manufacturing facility and undergoes rigorous four-round testing for every batch.
Value Assessment
Low value score because it is a single-ingredient product at a premium price point, but for users who want a pure, high-potency senolytic to pair with others, it is the safest choice.
Why Not Alternatives?
Many quercetin supplements use low-grade Chinese extracts that are poorly absorbed. Thorne's commitment to NSF Certified for Sport standards ensures no contaminants or undisclosed fillers.
