Quercetin is a plant-derived flavonoid — a natural antioxidant found in foods like apples, onions, and berries — that helps modulate inflammation and support immune function. Athletes use it primarily to help manage the inflammatory load from heavy training, reduce susceptibility to upper respiratory infections during high-volume periods, and control histamine response for those dealing with seasonal sensitivities.

Quercetin works best with consistent, cumulative use. Most people notice meaningful results after two to four weeks of daily use. For immune and inflammatory benefits, research supports chronic supplementation — think of it as a daily training aid rather than an acute fix.

Yes — and it's especially effective when stacked with Rho Liposomal Vitamin C. Vitamin C enhances quercetin absorption and adds its own antioxidant and immune-supporting benefits. All Rho products are designed to work synergistically and can be combined in the same drink for convenience.

Each bottle contains 30 servings at 6 ml each — a full 30-day supply. Refrigerate after opening for best taste and freshness.
