The Active Ingredient Is: Whey Protein

Whey protein is a complete protein source drawn from dairy, giving essential amino acids you need for normal body function and tissue upkeep. This formulation uses grass-fed whey concentrate with added probiotic cultures for quality and palatability.

This form is ultra-filtered whey protein concentrate sourced from grass-fed cows, designed to help support protein availability for muscle function and recovery.

What Does Whey Protein Do?

Whey protein helps to support muscle mass and recovery in healthy adults when you pair it with regular physical activity, contributing to maintenance of lean tissue. Research suggests improvements in muscle mass and strength gains during resistance training.

EFSA-aligned mechanisms show whey supplies rapidly digestible amino acids that help to support protein synthesis and repair after exercise.
