Got milk? Then take heart. Recently published research from the University of Reading in England has found that drinking over-the-counter, milk-based whey protein supplements may lower your heart disease and stroke risk.
The eight-week study examined the effects of whey protein on high blood pressure by testing 38 individuals identified as having pre- or mild hypertension. They were asked to drink two protein shakes a day for the duration of the study, consuming a combined total of four ounces of protein each day (mixed with the amount of water recommended on the packaging). The researchers found improvements in several key areas on both a daily and weekly basis. The reductions in factors that contribute to cardiovascular disease included:
- Reduced blood pressure over 24-hour period after whey protein consumptiomn
- Five percent decrease in LDL cholesterol levels
- Twelve percent decrease in triacylglycerol levels
By the study’s conclusion, the participants not only had lower cholesterol and blood pressure levels, but they also had reduced their risk of heart disease and stroke by eight percent.

The researchers used readily available off-the-shelf powdered whey protein supplements found in most supplement retailers. The amount administered was comparable to that consumed by bodybuilders and other high-performing athletes to increase muscle mass. The shakes comprised about ten percent of the recommended daily calorie allowance (214 calories), but this was offset by removing other foods from the diet to minimize or eliminate weight gain.
Considering that more than a third of adults in the U.S. suffer from some degree of high blood pressure, the whey protein supplement results are encouraging news. Though the benefits of milk and milk proteins have long been known and espoused, this new study is one of the first to address the specific effects milk proteins have on high blood pressure. While further studies are needed, the researchers believe that making whey protein part of a heart-healthy diet could play a significant role in reducing risk factors for cardiovascular disease.
