How to Choose

What the research says about casein protein

Scientific studies show that casein, particularly micellar casein, digests slowly and provides a prolonged release of amino acids into the bloodstream. This profile makes pre-sleep casein supplementation effective for increasing overnight muscle protein synthesis in both young and older adults when combined with resistance training. Research also supports casein's role in promoting fullness and helping with weight-management strategies when used as a controlled-protein option. It is important to consider individual tolerance, as casein is a dairy protein and may not be suitable for people with milk allergy or some forms of lactose intolerance.

Slow digestion: Micellar casein forms a gel in the stomach that slows gastric emptying and extends amino acid delivery.

Overnight recovery: Randomized studies show pre-sleep casein increases overnight muscle protein synthesis and aids recovery from resistance exercise.

Satiety and appetite control: Casein's slow release can help reduce hunger between meals, supporting weight-management plans.

Complete amino acid profile: Casein provides essential amino acids, including branched-chain amino acids that support muscle maintenance.

Tolerance and safety: Not suitable for people with milk allergy; those with lactose sensitivity should choose low-lactose or hydrolyzed options.

Quality matters: Choose products with transparent ingredient lists, third-party testing, and clear labeling for origin and protein type.
