Supports Muscle Gains

Whey protein isolate is the purest form of whey available. Unlike whey concentrate, whey isolate has had the fat and carbs from its milk source filtered out, leaving you with what you want—straight protein to help you build muscle and change your body composition, and no excess calories or sugar.

Whey isolate not only contains all the essential amino acids that the body needs to build muscle, it’s high in leucine—a branched-chain amino acid (BCAA) that signals muscle protein synthesis. Whey isolate has more leucine per gram than eggs, milk, or soy protein.

Promotes Workout Recovery

The sooner you get protein (and the leucine within it) into your muscles, the faster you can begin to recover from your workout. For hard training athletes and gym goers who partake in multiple activities per day, fast recovery between sessions is critical. Whey isolate delivers leucine to the muscles more efficiently than other protein supplements, making it a must-have for any post-workout shake.

cows

Grass-Fed*=Happy Cows

Our process produces an easily digestible and highly absorbable product. Using non-GMO ingredients, our whey is derived from the milk of New Zealand dairy cows that are able to graze pastures year round – largely avoiding the need for feed supplements. As a result, the cows aren’t subjected to feedlots, and are treated humanely. Plus, we've left gluten, lactose and sugar at the door, which makes for easier digestion.†

Rated 5 out of 5 by from Great protein powder Great product. Dissolves well in water and doesn't froth up when put in smoothies. Still need to blend it if putting in coffee as it will gum up if you don't. Very subtle flavor, not overwhelming vanilla or sweet like some.
