Why Quercetin for Immune
When it comes to immune, Quercetin is one of the most supporting nutrients to consider. Quercetin is a flavonoid found in onions, apples, and berries.

May also reduce blood pressure — a 2016 meta-analysis (7 RCTs) showed significant reduction in systolic BP at doses ≥500 mg/day.
