More Scientific Support for Soy Protein Heart Health Benefits

More Scientific Support for Soy Protein Heart Health BenefitsSoy protein is well known for its benefits in supporting healthy cholesterol and blood pressure. But, a recent study led by scientists in Tulane University School of Public Health and Tropical Medicine shows that soy protein supplements may also help reduce compounds that can impact blood vessel health. This new study compounds the benefits soy protein may have on cardiovascular health.

The study, published in the European Journal of Clinical Nutrition, is believed to be one of the biggest randomized trials to investigate the effect of protein supplementation on different bio-markers such as endothelial (lining of the blood vessel) function and adipocytokines, cell-to-cell signaling proteins secreted by fat tissue.1

The study consisted of 102 participants – men, women, Caucasians and African Americans – making it one of the most generalizable studies. During the eight-week trial period, the participants received randomized consumption phases of soy protein (48 grams a day with 89.3 milligrams of isoflavones), milk protein (40 grams a day) or complex carbohydrate which was administered as a placebo. This double-blind, three-phase crossover study showed no significant changes in certain biomarkers, except for a marker of endothelial function. Scientists observed remarkable reductions in E-selectin when compared with milk protein, and leptin, an adipocytokine, compared with the placebo.

Start Manufacturing Nutraceutical Supplements That Support Heart Health!

Soy protein powders are an excellent way to support heart health. The Food and Drug Administration (FDA) allows supplement manufacturers to make health claims on their soy products. The FDA states, “A health claim associating diets that are low in saturated fat and cholesterol and that include soy protein with reduced risk of heart disease may be made on the label or labeling of a food…”3

The American Heart Association currently recommends 25 mg of soy protein with phytoestrogens along with a low-fat diet to help lower the risk of cardiovascular health problems.4

That’s strong backing for soy protein supplements and a big impetus for supplement business owners to add soy protein powders to their product line.
