Protein is popular among athletes today. It is digested/absorbed into the body quickly to help return the body and muscles to an anabolic state.
SO, WHAT IS WHEY ISOLATE?To start, Whey Isolate is a dietary supplement. It is a bi-product of dairy and cheese. Whey ISOLATE contains the highest percentage of pure protein out of the different whey categories, and can be almost lactose, carbohydrate, fat, and cholesterol free. It is digested/absorbed into the body rapidly, making it a great source of protein intra and post workout. There is a high concentration of EAAs (Essential Amino Acids), CAAs (Conditionally Essential Amino Acids), and NAAs (Non-Essential Amino Acids) in isolate which are used to fuel your muscles and initiate protein synthesis necessary for muscle growth. Post workout, your body is in a catabolic state and wasting muscle tissue. Amino acid supply is critical to raise the rate at which your body synthesizes muscle tissue. Whey Isolate benefits the body at this point in time for both muscle growth and recovery.
HOW IS IT DIFFERENT FROM WHEY CONCENTRATE?
WHEY ISOLATE- The main difference between the two forms lie in the composition and protein content. Whey Isolate is manufactured through a process of ultrafiltration (the base component, water, is removed) to provide a higher protein content (above 90%) while retaining it’s bioavailability. There is minimal fat and carbohydrates, allowing one to monitor their macros more accurately. This is the perfect formula for someone looking to lose fat and gain lean muscle.
WHEY CONCENTRATE- This is the cheapest, yet most common form of Whey Protein. In these formulas you will find a significant amount of fat and cholesterol. Concentrates also are deceiving with the amount of pure protein actually found in the product. You may only find 29%-80% of actual protein per scoop. This means you pay less for an inferior product that will NOT deliver the results you are looking for. It also means more profits for companies selling these products.
I CAN FIND IT CHEAPER . . .
As stated above, there are different forms of Protein on the market. Isolate is a more bioavailable and nutrient dense form of whey, making it the purest form of Protein. Conversely, it is also one of the most expensive forms. Concentrates may only deliver a third of actual EAA/CAA/NAA that your muscles need post workout. There are also deceptive techniques of proprietary formulas and Amino Spiking to be wary of.
Proprietary formulas- Some formulas claim to have a combination of the different proteins to deliver optimal results. They may use a proprietary blend to protect their formula from being stolen. However, the FDA requires those proprietary blends to list the ingredients in order of weight. If Whey Concentrate is the 1st ingredient, you are being deceived and potentially paying more for a sub-par product.
Amino Spiking- Companies have also been found to add amino acids to their protein (example – 1g of Taurine, 1g of creatine, 1g of glycine added to 24g of Isolate = 27g of Protein) and count that weight towards their total protein count. While it is additional aminos, they are not beneficial for the anabolic state . . . So why do it? Some aminos are cheaper than others. Dumping more of a cheaper amino into the formula creates more profits and cuts the price down for the price conscious customer.
