Quercetin QUER

A plant compound studied, often paired with the cancer drug dasatinib, for clearing out old, damaged cells linked to aging. Early human trials combining the two show promising reductions in aging-related markers and some functional improvements in specific patient groups, though larger, more definitive studies are still needed.

Also known as Quercetin dihydrate, Meletin, Sophoretin, Xanthaurine, Quercetine, Quercetol, Quertine, Quercitin

Reported dosing

Clinical data

What has been reported in the literature and by users. This is a record of what is done, not a recommendation.

Typical dose 500 mg/day

Reported range 500-1000 mg/day (chronic); higher intermittent doses (500-1000 mg for 2 consecutive days per month) used in senolytic protocols, often paired with dasatinib

Route Oral

Frequency Once or twice daily (chronic) or short intermittent pulses (senolytic)

Duration Ongoing (chronic) or a few days per month (senolytic 'hit-and-run' dosing)

Sold as a dietary supplement; senolytic dosing protocols are extrapolated from early-phase human trials, not an approved indication.
