Milk Protein
15 results
Milk protein and casein are perfect alternatives to our super-popular whey protein. Packed with slow-releasing protein, they help to grow and maintain muscle between meals, and even while you sleep.
Taking much longer to be digested and used by the body, our slow-release and milk protein shakes deliver a sustained supply of protein, so you stay fuelled throughout the day.
