Yes whey

Whey protein is incontrovertibly one of the most widely used and accepted forms of protein available in supplement form. While some people avoid whey because it is a derivative of milk and/or milk products, others make a whey protein shake or two part of their daily diet. But, enter into any GNC or Vitamin Shoppe store and you'll immediately feel a wave of whey protein confusion roll right over you. There are so many brands and types of protein to choose from!! Well, to help you along, I'll at least explain the difference between whey protein concentrate and whey protein isolate.

As I said, I'm not going to get into a battle of the brands. That discussion is better left for weightlifting and nutritional supplement forums you can find with a quick Google search. However, I will do my best to help you decide if concentrate or isolate is better for you y explaining what separates one from the other. Starting first with whey protein concentrate, this form of whey protein is not as potent as isolate. It can contain anywhere between 29 and 89 percent protein. And, as the amount of protein in concentrate decreases, the amount of fat and/or lactose usually increases. As for whey protein isolate, this purer version contains at least 90 percent protein and little to no fat and lactose.

As you'd probably expect, whey protein isolate is more expensive than concentrate. But as the numbers show, you may actually be getting more for your money. In either case, don't just rush out and buy a giant jug of protein powder. Always speak with your doctor before taking nutritional supplements of any kind, whey protein certainly notwithstanding.
