Health Benefits of Whey Protein Isolate

Read on to find the top health benefits of whey protein isolate.

  1. Builds Muscle Mass

If you are working out and not replacing the lost protein in your body, it will only break down your muscles and not repair them in any way. Thus, all the hard work that you put in is wasted.

So to build muscle mass or maintain lean muscle mass and reduce fat at the same time it is important that you incorporate protein in your diet. And one of the effective ways to add protein is by including whey protein isolate.

  1. Good Source of Amino Acids

Whey protein isolate is the purest form of whey. It contains all the essential amino acids that are needed by the body for repair after a workout session. As you know that essential amino acids are not produced in our body, thus, we need to get these through health supplements or food sources. If you don’t get essential amino acids, it may lead to muscle loss and problems in muscle repair.

  1. Aids Digestion

Whey protein isolate aids digestion. It regulates bowel movement and can also be consumed by people who are lactose intolerant. Whey protein isolate just has 1% lactose. Also it doesn’t have any fat or carbohydrates, so it can be easily digested. It gets absorbed quickly and also gets processed by the body quickly, especially when you consume it as a liquid. So if you are looking for lean muscles, then whey protein isolate is what you need to include in your diet.

  1. Helps Reduce Blood Pressure

In a study conducted it was showed that certain kinds of protein in whey have peptides which are known to reduce blood pressure. To prove this further an Australian research was conducted and it was found that when men and women were given 27g whey protein twice a day for 12 weeks, it showed 4% reduction in systolic blood pressure and 3% reduction in diastolic blood pressure.

  1. Helps Reduce Symptoms of Stress and Depression

Whey Protein has two specific Amino Acids – tryptophan and glutamine. Both these amino acids are closely associated with stress, anxiety, and depression.

Tryptophan – it aids in production of serotonin. If you have low levels of serotonin in your body, it can make you stresses and anxious. So by increasing the intake of tryptophan you are automatically increasing serotonin levels in your body which in turn will help reduce symptoms of stress and depression.

Glutamine – it is the precursor of gamma-aminobutyric acid. It reduces anxiety and helps you stay calm.

  1. Promotes Muscle Growth

Whey Protein Isolate contain high amount of leucine. Leucine is the component which helps in synthesis of muscle protein and helps in muscle growth. It also aids in loss of fat tissues because of the energy the body consumes while processing leucine.

As compared to soy protein, whey protein isolate has 50% more leucine, thus, is a better choice if you are considering fat loss and muscle building.
