Casein - the "Nighttime Protein"
Casein is the main protein fraction of milk and is characterized by slow digestion and continuous amino acid release. In the stomach, casein forms a gel structure, which means that amino acids are released over several hours – in contrast to whey protein, which is rapidly absorbed.
Studies show that casein, especially at night or during rest periods, positively influences protein balance and can thus inhibit muscle breakdown. This makes it ideal as a supplement to rapidly available proteins and as part of a long-term diet for muscle building, maintenance, and regeneration.
Benefits at a Glance
Science & Background Knowledge
Slow absorption
In the stomach, casein forms a gel structure that allows for continuous amino acid release for up to 7 hours.Casein vs. Whey
While whey is absorbed quickly, casein provides a steady supply of protein over longer periods.Night Protein Effect
Studies show that casein intake before sleep promotes nocturnal muscle protein synthesis and inhibits breakdown.FAQ – Frequently Asked Questions about the product
Casein is digested more slowly, making it ideal for nighttime use, while whey is optimal directly after a workout.
Best taken in the evening before bed or during long breaks between meals.
Yes, by providing long-lasting satiety, it supports a calorie-conscious diet.
Both options are possible: with milk, the consistency becomes creamier; with water, it's lighter and has fewer calories.
Casein contains natural milk components, therefore it may contain small amounts of lactose.
