Effect of vitamin C on endothelial function in health and disease: A systematic review and meta-analysis of randomised controlled trials
Highlights
•Vitamin C supplementation improved endothelial function (EF).
•The effect of vitamin C appeared to be dependent on health status.
•Stronger effects in those with cardio-metabolic disorders.
•No effect of vitamin C was observed in healthy volunteers.
•Vitamin C dose greater than 500 mg/d was associated with beneficial effects on EF.
Note: It is hard to take a "meta analysis" seriously after reading Hickey's TARNISHED GOLD.
