Whey Protein Isolates are 90% pure protein by weight. They are the purest and most expensive form of whey protein that exists. That’s why they are the first ingredients you read on the 100% Whey Gold Standard label. By using Whey Protein Isolates as our primary protein source, we’re able to pack 24 grams of the purest, muscle-building protein per serving, with a lot less of the fat, cholesterol, lactose, and other stuff that you can do without. There’s no question this is the standard by which other whey proteins are measured.

To encourage a positive nitrogen balance, consume approximately 1 gram of protein per pound of body weight per day from a combination of high protein foods and supplements. For even better results, consume your daily protein allotment over 4-6 small meals spread evenly throughout the day.

Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day.

Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken-down into their amino acid subcomponents than whey and other proteins. Because of their unique time-released qualities, caseins are aptly described as anti-catabolic or muscle-protecting proteins.
