Nutrition & ingredients
Each 30 g serving provides 25 g of protein, 0.5 g of fat and less than 1 g of carbohydrates. ISO100 uses hydrolyzed whey protein isolate as its primary source, which is processed into smaller peptides. This form is often noted in nutrition discussions as easier to digest than standard concentrates.
The formula is lactose‑free, gluten‑free and contains soy lecithin to support mixability. It is sweetened with sucralose. ISO100 is also Informed‑Choice certified, meaning it is tested for banned substances, which is particularly relevant for competitive athletes.
Taste & mixability
Customer reviews suggest Dymatize ISO100 has better taste than many hydrolyzed isolates, which can sometimes be bitter. Flavours like Gourmet Chocolate and Fruity Pebbles are described as smooth and palatable, while the “Clear” range (e.g., Orange Cream) is lighter and more refreshing.
Mixability is frequently praised: the fine powder dissolves easily in water with minimal foam or clumping. Users also report it blends well with milk alternatives, oats and smoothies.
Use cases
ISO100 is marketed for athletes and active individuals who want a very lean protein powder with rapid digestion. Many customers choose it around training sessions because it is low in carbs and fats, while others use it as a daily supplement to boost protein intake.
Because it is lactose‑free, ISO100 is often selected by those who cannot tolerate concentrates or blends containing dairy sugars. Users following calorie‑controlled diets also highlight its macro profile as a benefit.
Value
ISO100 sits in the premium category of protein powders. While it is not the cheapest option, customer feedback often points to its quality, flavour options and banned‑substance certification as reasons they continue to repurchase.
