This latest study revealed that whey protein has a normalizing effect on blood pressure levels, reducing levels significantly in those at risk of hypertension. This may be due to whey’s impact on nitric oxide production, as nitric oxide helps your vessels maintain their elasticity and its suppression leads to increases in blood pressure.
This benefit extends not only to those with, or at risk of, high blood pressure; it’s important to maintain healthy blood pressure levels too.
One recent study found, for instance, that supplementation with the whey-derived peptide NOP-47 had a positive impact on vascular function in healthy people. Blood flow in the arm improved by 2.7 percent per minute following whey protein supplementation, but did not change for those in the control group who took a placebo.
So in choosing a protein powder as a meal replacement, protein source or exercise recovery drink, you’ll support healthy blood pressure levels just by choosing whey.
