Hydrolyzed Whey Isolate for Faster Absorption

ISO100 stands out from many isolates because it’s hydrolyzed — the protein is partially broken down into smaller peptides before it hits your shaker, which speeds up digestion and absorption. Dymatize processes it using cross-flow microfiltration, a multi-step method that strips out excess carbs, fat, lactose, and cholesterol while preserving the protein fractions that matter.

Each serving delivers 25g of protein and 5.5g of BCAAs at under 120 calories, and it’s gluten-free and banned-substance tested. It comes in a wide range of flavors, which makes it easier to stick with long-term compared to isolates that only ship a couple of options.

Key Specs at a Glance

Who It’s For

A strong pick for anyone who wants faster protein absorption immediately post-workout, or anyone with mild lactose sensitivity, since the microfiltration process strips out most lactose. It’s also a good fit for anyone counting calories closely, since it delivers 25g of protein at under 120 calories per serving.

What We Liked

• Hydrolyzed formula genuinely speeds up digestion and absorption compared to standard isolates
• 25g of protein and 5.5g of BCAAs at under 120 calories per serving is a strong macro ratio
• Cross-flow microfiltration process strips out most lactose, fat, and excess carbs
• Wide flavor selection makes it easier to stick with long-term

Things to Consider

• Hydrolyzed whey often costs more than standard whey isolate due to the extra processing step
• Still whey-based, so it’s not suitable for vegan or dairy-free diets despite the reduced lactose content
