Casein Protein powder is a slow-digesting, high-quality milk protein derived from skimmed milk. It accounts for about 80% of the protein in cow’s milk and is well-known for its sustained amino acid release, making it ideal for muscle recovery during sleep and long periods without food intake.
Compared with whey protein, which digests quickly, casein forms a gel-like structure in the stomach, resulting in a gradual and prolonged release of amino acids into the bloodstream.
🕐 Slow absorption rate – ideal for overnight recovery
💪 Rich in essential amino acids & BCAAs – supports lean muscle growth
🛡 Anti-catabolic properties – prevents muscle breakdown
🥛 High calcium & phosphorus – supports bone health
🍽 Satiety effect – promotes fullness, helpful in weight management
Micellar casein, cold-processed to preserve bioactivity
Non-GMO, gluten-free, allergen-controlled
≥90% protein content with complete amino acid profile
Produced under GMP, ISO, HACCP standards
Ideal for sports nutrition, meal replacements, and functional foods

Q: What is casein protein powder?
A: Casein protein powder is a slow-digesting dairy protein derived from milk. It makes up about 80% of milk’s protein content (with whey being the other 20%). Its key characteristic is that it forms a gel in the stomach, leading to a slow, sustained release of amino acids into the bloodstream over several hours.
Q: What is micellar casein protein powder?
A: Micellar casein is the gold standard and most natural form of casein powder. It is produced using a low-temperature filtration process that preserves the protein’s natural micelle structure. This intact structure is what causes its very slow digestion rate, making it ideal for providing a steady supply of amino acids.
Q: Does whey protein powder contain casein?
A: Standard whey protein isolate and concentrate contain negligible or zero casein, as they are separated from it during processing. However, some “milk protein” or “blend” products intentionally combine both whey and casein proteins.
Q: How is casein protein powder made? / What is it made from?
A: It is made from skim milk. The milk is gently processed (often via microfiltration) to separate the casein micelles from the liquid whey, fat, and lactose. The extracted casein is then spray-dried at low temperatures to create a powder, preserving its slow-digesting properties.
Q: How to use casein protein powder?
A:
Primary Use: Best taken before bed to fuel muscles with a slow release of amino acids overnight, aiding recovery and reducing muscle breakdown.
Other Uses: As a meal replacement between meals due to its satiating effect.
Mixing: It thickens significantly when mixed with liquid. Use a shaker bottle or blender. It’s ideal for making protein puddings or mixing into Greek yogurt.
