What Is It?
Whey comes from milk, which is actually comprised of two proteins: casein, which makes up approximately 80 percent of milk protein, and whey, which makes up the other 20 percent. When milk is turned into cheese, whey is separated from the solid curds and can be found in the liquid that is left behind.
Once separated, it goes through several more processing steps to become what most people recognize as whey protein: a relatively tasteless powder that can be added to shakes, protein bars, or even baked goods. It's a common protein booster in commercial smoothies, bars, cereals, and plenty of other foods, but can also be taken on its own.
Whey Protein Isolate goes through an even further process in which the protein is separated even more from the other nutrients. This extra filtration process makes it even more pure. Essentially, whey protein isolate is a form of whey. It is the cleanest, purest form of whey protein; as it is generally 90-95% protein. This leaves little room for anything else. If you see ‘100% Whey Protein Isolate’ on the label, like in TC Nutrition's IsoShock, just know that you’re putting a higher quality product into your body.
What Does It Do?
For starters, whey is a complete protein, meaning it has all nine essential amino acids necessary for protein synthesis. We call these amino acids "essential" because your body can't make them and therefore you must consume in them in your diet.
Whey is particularly high in the group of three essential amino acids known as BCAAs: leucine, isoleucine, and valine. These help to build and maintain muscle, and can also serve as an energy source during prolonged or intense workouts.
Leucine, specifically, has been shown to have the greatest impact on rates of muscle protein synthesis, the process that makes your muscles bigger and stronger. One 25-gram scoop of whey protein has approximately 3 grams of leucine.
What Is It Made Of?
- Bovine serum albumin (BSA)
- Immunoglobulins (IgG1, IgG2, secretory IgA and IgM)
- Smaller components: iron binding proteins (lactoferrin, lactoferricin), calcium, potassium, sodium, phosphorous, folic acid, biotin, and vitamins A, C, B1, B2, B3, B5, and B12.
Whey is made up of many smaller protein subfractions such as beta-lactoglobulin, alpha-lactalbumin, and immunoglobulins (IgGs). Each of these subfractions has its own unique biological properties. The protein subfractions are made out of amino acids.
Like all proteins—chicken, beef, egg, soy, rice, hemp, and so on—whey is composed of amino acids, which the body can use for muscle growth and tissue repair. But it's whey's high concentration of branched-chain amino acids (BCAAs), especially leucine, that sets this protein apart from the others.
What’s So Special About This Protein?
Whey Protein Isolates contain 90-95% percent protein, with little to (virtually) no amounts of lactose and fat. TC Nutrition's Whey Protein Isolate, IsoShock boasts an incredible 90% protein content per scoop.
Whey Protein Isolates will contain more protein on a gram-for-gram basis than a concentrate. A high-quality isolate, like ours here at TC Nutrition, will not contain some of the compounds found in milk. Because of this, they are safe for those who are lactose intolerant.
Whey protein is popular among athletes, bodybuilders, and fitness enthusiasts alike today because of its ability to be digested very rapidly. Additionally, one of the most notable benefits of Whey Protein Isolate is that it helps return the post-workout body back from a catabolic (muscle-wasting) state to an anabolic(muscle-building) state. This means that Whey Protein Isolate helps you preserve and build muscle, especially when your body is in the state of wasting muscle and using it as fuel.
Whey Protein Isolates are also widely used in infant formula to provide a natural source of amino acids for optimal growth and development, as well as for protein fortification of bars, beverages, dairy products, extruded snacks and cereals and other food product.
Whey Protein Isolate vs. Whey Protein Concentrate
There has been long debates about which type of protein is better; whey protein isolate or whey protein concentrate. However, the truth is that there isn't definite answer. In fact, the most assuring answer is: “it depends”. It depends on your personal nutrition and fitness goals. There are differences between whey protein isolate and whey protein concentrate, and one may cater to your wants and needs more than the other. Whey protein isolate has a higher protein content and is lower in carbohydrates, lactose and fat, which is beneficial for anyone. All in all, it’s worth considering to yourself whether the additional benefits are necessary for you. If you are lactose intolerant, and conscious about your carbohydrate and fat intake, then TC Nutrition's Whey Protein Isolate, IsoShock is definitely for you.
