Bio-Quercetin® uses a quercetin combined with fibers from fenugreek seeds to increase bioavailability. The result: a science-based quercetin supplement that far outclasses standard quercetin formulations.

What Is Bio-Quercetin?

Quercetin encourages heart health and supports a healthy immune response. But like many phytonutrients, quercetin isn’t easy to absorb. So we combined quercetin with fenugreek seed fibers to enhance "free" quercetin up to 18x (with up to 62x better total bioavailability) over standard quercetin formulas.

Bio-Quercetin® Benefits

  • Delivers 18x more bioavailable free quercetin (up to 62x better total bioavailability)*
  • Promotes immune, cardiovascular & endothelial health
  • Helps protect against oxidative stress & supports a healthy inflammatory response


30 vegetarian capsules

Suggested Use

Take one (1) capsule daily, or as recommended by a healthcare practitioner.
