The Active Ingredient Is: Whey Protein Isolate

Whey Protein Isolate is a premium dairy protein that delivers all essential amino acids and is quickly absorbed by your system.

This variant comes from milk and offers a purer protein option in the blend, with AstraGin and DigeZyme added to aid nutrient uptake and protein digestion.

What Does Whey Protein Isolate Do?

Whey Protein Isolate helps support normal muscle function and post‑exercise recovery as part of a balanced training routine. It helps the body meet its daily protein needs and supports nutrient uptake when you train. [What’s more this keeps you fuelled during tough workouts and recovery periods.]

Dr. Hartman at the University of Nebraska found that high‑quality whey protein can aid muscle recovery and hypertrophy when paired with resistance training. [That finding is interesting because it links nutrition with exercise results.]
