Nano Quercetin Capsules - 250 mg (120 Count) delivers 250 mg of ultra-absorbable quercetin per capsule, a potent flavonoid found naturally in onions, apples, berries, and green tea. Known for its antioxidant activity and cellular protection, quercetin is widely studied for its ability to support histamine response, cardiovascular function, and metabolic health. Nano-sizing the particles dramatically enhances absorption, making it far more bioavailable than standard quercetin supplements.
Nano Quercetin Capsules - 250 mg (120 Count)
Quercetin is typically poorly absorbed by the body. Our proprietary nano-sizing process reduces the particles to 1–100 nanometers, smaller than the body’s absorption channels (~200 nm). This allows for faster uptake and more efficient delivery into the bloodstream.































Reviews
I developed a histamine-related skin disorder & developed hives ALL over my body. I was MISERABLE! Pharma anti-histamines provided some relief but it wasn't until I started taking this Quercetin that real improvement occurred. After a therapeutic dose was determined, my histamine levels improved, itching decreased & I was able to cut back on the Rx anti-histamine. Lastly, systemic inflammation--a big factor in managing this auto-immune skin disorder--also decreased. OPN Quercetin is terrific!
