Protein is a fundamental macronutrient essential for everyday body functioning and tissue upkeep. This product uses a whey protein blend, mainly sourced from whey protein isolate, to deliver a complete amino acid profile for muscle support. This form mixes whey protein isolate with whey concentrate and hydrolysed whey, offering a high quality source of dietary protein fit for active folks.
Protein helps build muscle and aids recovery after training, with evidence that benefits show up when eaten around workouts. It helps support lean mass and overall protein intake for active people, in line with EFSA style guidance. Dr. Phillips from the University of Illinois found that whey protein supplementation with resistance training can support lean muscle mass and recovery in athletic populations. This product isn’t meant to diagnose, treat, cure, or prevent any disease.
