What Is Bio-Quercetin?

Quercetin is right up there with vitamin C as one of the most powerful nutrients for immune health, and it benefits your heart, too. But like many phytonutrients, quercetin isn’t easy to absorb. So we wrapped it up in a phytosome, a plant-based, phospholipid sphere that makes this formula up to 50 times more available than conventional quercetin.

Looking for a quercetin supplement? Take the one that absorbs up to 50x better. Now that’s a healthy decision!

Bio-Quercetin® Benefits

  • Promotes immune, cardiovascular & endothelial health
  • Helps protect cells from oxidative stress
  • Supports a healthy inflammatory response


Quercetin: Uncommonly good for you

Looking to give your health regimen a boost? Add quercetin. This flavonoid from plants helps maintain already-healthy blood pressure by promoting endothelial health and supports your immune system’s ability to fight off both seasonal and yearlong challengers. Plus, it’s good at neutralizing free radicals before they cause oxidative stress. And our ultra-bioavailable formula makes sure your body absorbs these remarkable benefits.

More facts about Bio-Quercetin

Our Bio-Quercetin® contains a form of quercetin that has been integrated into a phytosome. A phytosome is a tiny sphere made out of plant-derived phospholipids. By combining quercetin with this phospholipid-based delivery system, the quercetin in this formula is more bioavailable, making it easier to absorb and more readily used by the body.1
