Product details:
Health benefits at a glance:

Quercetin is a highly versatile bio-flavonoid that can promote a wide variety of health aspects. But, like many phytonutrients, quercetin is difficult for the body to absorb. By combining it with fenugreek seed fibers, the bioavailability is significantly improved, compared to standard, unformulated quercetin.

Why it works

Quercetin has a long tradition of being used for relieving the effects of seasonal immune challenges. It is shown to promote heart health and offer support for the immune system and inflammatory response.

The science behind the product

Clinically backed for better bioavailability

In a randomized clinical trial, bio-quercetin formulated with fenugreek fibers was compared to standard, unformulated quercetin. Results showed serum levels of total quercetin were up to 62 times higher, while free (unconjugated) quercetin reached levels up to 18 times greater. (1)

Promoting cardiovascular & endothelial health

Quercetin is shown to support cardiovascular health, promote endothelial function, and help maintain already-normal blood pressure. (2,3)

It is also a strong antioxidant, inhibiting oxidative stress and promoting a balanced inflammatory response. (4,5)

Strong immune system support

Quercetin can promote a healthy immune function during seasonal challenges. In a clinical study, it helped physically fit older adults maintain a healthy immune response. (6)
