Casein Protein

Casein Protein is a slow-digesting, sustained-release protein that delivers a steady stream of amino acids over several hours. It’s perfect for supporting recovery while you sleep, between meals, or anytime you want prolonged nourishment to keep your muscles fuelled and protected.

Derived from milk, Casein makes up around 80% of the protein found in dairy and is known for its thick, creamy texture and gradual absorption rate. Unlike fast-acting whey, which spikes amino acid levels quickly after training, Casein forms a slow-digesting gel in the stomach. This unique property allows it to release amino acids into the bloodstream for up to seven hours, helping reduce muscle breakdown and improve overnight recovery.

Casein Protein is especially beneficial for those in calorie deficits, extended fasting periods, or anyone looking to preserve lean muscle mass between meals. It’s also more satiating than many other proteins, helping you stay fuller for longer and manage cravings.

Because of its naturally rich and smooth consistency, Casein is ideal as a bedtime shake or a high-protein addition to recipes like puddings, yoghurt bowls, or baking mixes. When paired with a fast-digesting protein such as Whey Isolate, it creates an effective day and night recovery system to keep your body in an optimal anabolic state.
