A Protein Blend Built for Sustained Amino Acid Release

Muscle Milk Genuine Protein Powder leans on a mix of milk protein isolate and whey protein concentrate — a combination of faster and slower-releasing proteins designed to keep amino acid levels elevated longer than a whey-only shake. Each serving (2 scoops) delivers 32g of protein along with all 9 essential amino acids, plus calcium and vitamins A, C, and D.

It’s NSF Certified for Sport, screened for more than 270 substances banned by major athletic organizations, and contains no caffeine or creatine, so it layers cleanly with whatever else is in your stack. At about 270 calories per serving with 2-4g of sugar depending on flavor, it works equally well as a post-workout shake or a between-meals snack.

Key Specs at a Glance

Who It’s For

A good fit for anyone who wants a heartier, more calorie-dense shake than a lean whey isolate — someone using it as a meal replacement or between-meals snack rather than just a light post-workout top-up.
