“The STAMINA results provide encouraging clinical evidence consistent with that hypothesis, demonstrating improvements across three measures of cardiovascular function, particularly meaningful given that cardiovascular disease remains the leading cause of death worldwide.”

To learn more, 61 participants were recruited, 33 of whom received the supplement and 28 a placebo (control group). Participants were asked to consume the supplement or a placebo once daily for six months.

Researchers found that flow-mediated dilation, a measure of endothelial function (regulation of blood vessel tone and blood clotting), improved in participants receiving the supplement compared with the control group. An improvement was also observed one hour after the first dose, while values remained largely unchanged in the control group.
