Choose Curcumin (Turmeric) if
Curcumin (Turmeric) is the better fit when your goal aligns with its mechanism (Inhibits NF-κB transcription factor activation, suppressing dozens of downstream pro-inflammatory cytokines (TNF-α, IL-6, IL-1β)) and the dose range (500–2000mg) suits your protocol. Half-life is —h.
Choose Quercetin if
Quercetin is the better fit when your goal aligns with its mechanism (Senolytic activity that is substantially amplified when combined with the prescription drug dasatinib — this combination (D+Q) is the most-studied senolytic intervention in current human trials) and the dose range (250–1000mg) suits your protocol. Half-life is —h.
