Whey Protein Isolate

If you’re an athlete, or just looking to get in better shape, the best place to start with supplementation is unquestionably whey protein. Unfortunately for everyone just beginning their research on what supplements are best for them, whey protein can actually be somewhat complex as there are various forms that all aim to accomplish different goals.

Whey protein isolate is a unique form of whey that enables users to receive incredible high-quality protein with little to no fat or carbohydrates, as well as the added benefit of containing zero lactose which makes it perfect for those who are sensitive to dairy products.

What it does

Whey protein isolate has been shown to significantly increase muscle gains[1], enhance the hormonal response to exercise by reducing cortisol release[2], reduce body fat[3], and increase strength and power.

How it works

Whey protein isolate gives athletes and those looking to get in better shape an easy way to consume all the protein necessary in their diet. Protein requirements often cause one of two issues for users in that it can be hard for some to consume enough protein in their diet (as they are not hungry enough to reach their daily goals), or that by consuming so much protein they consume too many calories, and end up gaining unwanted body fat.

Whey protein isolate helps tackle both issues as each serving usually provides about 25g of protein for the user, making it easy to add on an extra 50-150g of protein each day with little to no work. On the other side of the coin, while traditional foods such as steak, milk, peanut butter, or other high protein options contain high levels of fat and therefore calories. Whey protein isolate usually comes with 1g or less of both carbohydrates and fats, letting the user get all the protein they need without maxing out their daily caloric goals.

In its most simple terms, whey protein isolate works by increasing rates of muscle protein synthesis, or how quickly the body is able to break down protein into amino acids, and use it to rebuild and repair damaged muscle fibers (which we receive from intense exercise). By increasing this bodily process, we are able to experience the benefits of faster muscle growth and fat loss, as well as enhanced athletic performance.

Dosing

Whey protein isolate should be used as needed to reach your daily macronutrient goals. Most suggest using 1-2 scoops (usually 25-50g of protein) at a time to mimic a traditional meal (as 4-8oz of chicken or beef contains similar protein totals), and this can be used however many times per day as needed to reach total goals.
