Quercetin's senolytic mechanism — BCL-2 protein inhibition triggering apoptosis in senescent cells — requires achieving plasma concentrations above the senolytic IC50 (approximately 10–25 μM quercetin). This is achievable with phytosome form (500–1,000 mg/day) but not with standard extract at the same dose. The burst protocol mirrors fisetin: 2 consecutive days per month or quarter.

Does fasting state affect quercetin senolytic activity?

There is a trade-off: fasted state reduces quercetin absorption (reducing plasma levels) but may enhance senolytic activity by lowering cellular ATP and reducing BCL-2 expression in senescent cells. Fat-containing meal strikes the best balance — improving absorption without abolishing the senolytic context.

Can I take quercetin phytosome every day at high dose?

Safety data supports continuous use. However, very high doses (>1,000 mg/day continuous) may theoretically promote excessive cell death beyond senescent cells. The burst protocol is evidence-based; daily ultra-high dosing is not.
