{"product_id":"quercetin-capsules","title":"Quercetin One - 60 x Quercetin 500mg Capsules","description":"\u003cp\u003eCellular energy production has a cost. Every time your mitochondria turn fuel into ATP, they produce oxidative byproducts. Healthy cells handle the byproducts through antioxidant defense systems. As you age, those defense systems get less efficient and the byproducts accumulate.\u003c\/p\u003e\u003cp\u003eQuercetin is one of the most studied flavonoids for supporting that antioxidant defense layer.\u003c\/p\u003e\u003ch3\u003eWhy antioxidant defense matters for longevity\u003c\/h3\u003e\u003cp\u003eOxidative stress is a slow tax on cellular function. It accumulates over decades, contributing to the gradual decline that compounds into the visible signs of aging. The body's natural antioxidant systems (glutathione, superoxide dismutase, and others) handle most of it — but they need raw materials, and they work better when supported.\u003c\/p\u003e\u003cp\u003eQuercetin acts as a direct antioxidant and supports the body's natural antioxidant enzymes. It also has senolytic properties — meaning it helps the body clear senescent (zombie) cells that have stopped dividing but won't die, and leak inflammatory signals into surrounding tissue.\u003c\/p\u003e\u003ch3\u003eHow Quercetin One works\u003c\/h3\u003e\u003cp\u003e500mg of quercetin per capsule supports the cellular protection side of the longevity picture. Pairs cleanly with NMN and trans-resveratrol — NAD+ supports cellular energy supply, quercetin supports the protection layer that keeps those cells functioning under stress.\u003c\/p\u003e\u003ch3\u003eWhat's in each capsule\u003c\/h3\u003e\u003cp\u003e500mg of quercetin dihydrate (≥98% purity). One capsule per serving. Hypromellose capsule, rice flour, no proprietary blends, no synthetic additives.\u003c\/p\u003e\u003ch3\u003eWho it's for\u003c\/h3\u003e\u003cp\u003eAdults 40+ who already take NMN or another NAD+ support and want to add the antioxidant defense piece. People whose longevity routine has the build side covered and is ready for the protect side. Anyone whose research has pointed them toward quercetin as the next addressable pathway.\u003c\/p\u003e\u003ch3\u003eHow to take it\u003c\/h3\u003e\u003cp\u003eOne capsule daily with a meal that contains fat — quercetin is fat-soluble, and absorption is meaningfully better with food. Morning or with lunch both work. Consistency over months is what matters.\u003c\/p\u003e\u003ch3\u003eWhat to expect\u003c\/h3\u003e\u003cp\u003eAntioxidant support works at the cellular level over weeks and months — not days. Most people don't feel an immediate shift. The compounding benefit shows up as steadier cellular function under stress, faster recovery, and the kind of resilience that's easier to feel a year later.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThese statements have not been evaluated by the Food and Drug Administration.
