Quercetin

A randomized, double-blind, placebo-controlled trial in 71 overweight participants (35 in quercetin group, 36 in placebo) over 12 weeks found that 100 mg daily quercetin significantly lowered participants' weight and body fat percentage, with both groups showing reduced blood glucose and leptin levels.

A 10-week double-blind randomized clinical trial in 72 females with type 2 diabetes found that 500 mg daily quercetin significantly reduced systolic hypertension compared to placebo and decreased inflammatory markers TNF-α and IL-6, with improvements in total cholesterol, LDL, and triglycerides.

A double-blind, placebo-controlled, cross-over trial in 41 participants (19 with prehypertension and 22 with hypertension) found that 730 mg quercetin over 28 days significantly reduced systolic and diastolic blood pressure in hypertensive subjects, though blood pressure did not change in prehypertensive subjects.
