Whey Protein Improves Heart Health
August 29, 2009
A whey-protein-rich ingredient may improve blood vessel function in healthy individuals, reports a new randomized, double-blind study.
Two weeks of supplementation resulted in a 1.5 percent improvement in blood flow. According to the researchers, the whey protein-derived ingredient may work via an angiotensin converting enzyme (ACE)-inhibitory activity.
ACE inhibitors work by inhibiting the conversion of angiotensin I to the potent vasoconstrictor, angiotensin II, thereby improving blood flow and blood pressure.
