May Lower Blood Pressure
A small amount of scientific research indicates that whey protein has the potential to lower blood pressure. However, more studies are necessary before any conclusive evidence can be considered. There are more studies currently being conducted on this very subject. If individuals take whey protein to lower blood pressure, it should always be in addition to their blood pressure medication and other regimens their doctor has prescribed. Individuals should tell a doctor if they are starting protein or herbal supplements to help manage a health condition.
A small study with preliminary evidence was published in 2016. In the study, forty-two volunteers who experienced a slight elevation in blood pressure were recruited. Each participant drank two protein shakes per day. For those who had fifty-six grams of whey protein per day, there were approximate drops of three points in the average systolic blood pressure readings and two points in the average diastolic blood pressure readings.
