This quercetin complex delivers targeted antioxidant protection to support your immune system and cellular health. Unlike basic quercetin supplements, this formula combines 250mg of quercetin with complementary bioflavonoids for enhanced absorption and effectiveness.
Why It Works
PROVEN ANTIOXIDANT: Quercetin is backed by research showing its ability to neutralize free radicals and support normal immune response.
ENHANCED ABSORPTION: Grape seed extract with 80% proanthocyanins improves quercetin bioavailability compared to quercetin alone.
SYNERGISTIC BLEND: Blood orange extract, turmeric with 95% curcuminoids, and CoQ10 provide complementary antioxidant pathways.
What's Inside
Clean vegetarian capsule formula with no artificial fillers. Each capsule delivers clinically studied amounts of quercetin plus supporting bioflavonoids.
Why we carry it: Natural Factors formulates quercetin with bioflavonoids that actually enhance absorption, not just add ingredient count.

Natural Factors Quercetin
I typically switch brands of quercetin as I use it as a preventative and like to have a broader choice. I had not tried the Natural Factors brand before. It seems to have the desired effect for me so I will continue with this brand in my rotation.
