Quick answers
Is this right for you?
Who is it for?
Dymatize Nutrition ISO 100 is designed for athletes, lean-bulk dieters, and anyone who wants maximum protein with minimal fat and carbs. Whey isolate is also a better option for people with mild lactose sensitivity, since the extra filtration removes most of the lactose.
What can you expect?
A lean, fast-absorbing protein with very low fat and carbohydrate content. Whey isolate goes through extra filtration to deliver 85-95% protein purity, which means more protein per scoop and fewer calories from filler. Expect quick absorption, making it ideal straight after a workout. With 79g of protein per 100g (around 25g per 32g serving), Dymatize Nutrition ISO 100 sits in a solid mid-range for a whey isolate product.
