Dymatize ISO-100 is a super clean 100% whey isolate protein powder for athletes who want protein - and only protein - in their shakes. Whey isolate protein has been purified to remove even more non-protein components than whey concentrates. This adds to the cost but for elite athletes or dedicated bodybuilders who watch every gram of carbs and fat, it's worth the extra expense. With one gram or less of carbs no matter which flavor you choose, Dymatize ISO-100 gives you 24 grams of protein per serving. Expect easy-mixing and a clean, light taste when you mix up a protein shake with a 100% whey isolate supplement like Dymatize ISO-100. This product contains 5 lbs of whey protein powder.
