Clinically Studied for Greater Bioavailability

In a randomized clinical study, researchers compared the formulated Bio-Quercetin to unformulated quercetin. They found that the quercetin formulated with fenugreek fibers led to serum levels of total quercetin up to 62 times higher than unformulated quercetin, and 18 times higher levels of free (unconjugated) quercetin.¹

Supports cardiovascular and endothelial health

Quercetin promotes both cardiovascular and endothelial health and helps maintain healthy blood pressure already within the normal range.^2,3 Quercetin is also a potent inhibitor of oxidative stress and helps promote a healthy inflammatory response.^4,5

Promotes a Healthy Immune Response

Quercetin promotes a healthy immune response in the face of seasonal immune challenges. In a randomized clinical trial, quercetin encouraged a healthy immune response in physically fit older adults.⁶
