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

Life Extension’s 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.

Clinically Studied for Greater Absorption

In a randomized clinical study, researchers compared two orally administered quercetin phytosome doses (providing 100 mg and 200 mg of quercetin), along with one 500 mg dosage of traditional quercetin. They found that the quercetin phytosome could be administered at one-fifth the dosage of the traditional quercetin and still result in exposure 10 times greater. This means that the quercetin phytosome provides about 50 times greater bioavailability than traditional quercetin.

Promotes a Healthy Immune Response

Quercetin has a long tradition of use for promoting a healthy immune response in the face of seasonal immune challenges. In a randomized clinical trial, quercetin supplementation encouraged a healthy immune response in physically fit older adults. Another randomized controlled trial showed similar findings in trained athletes. And in double-blind clinical trials, quercetin promoted a healthy inflammatory response, inhibited oxidative stress and helped maintain overall health.

Supports cardiovascular and endothelial health

Quercetin promotes both cardiovascular and endothelial health and helps maintain healthy blood pressure already within the normal range. Quercetin is also a potent inhibitor of oxidative stress and helps promote a healthy inflammatory response.
