Casein Protein is the primary protein found in milk, comprising about 80% of the total protein content. It is a slow-digesting protein that provides a steady release of amino acids into the bloodstream, making it especially beneficial during periods of prolonged fasting, such as overnight.
In athletic contexts, casein is valued for its muscle-preserving effects and is often used before bedtime to prevent muscle breakdown. Its prolonged absorption can also help promote satiety, aiding in weight management strategies.
Due to its rich amino acid profile, casein supports muscle repair and growth, making it a staple in sports nutrition for those aiming to build or maintain lean mass.
Synonyms:
Micellar casein, Calcium caseinate
Benefits:
- Provides sustained amino acid release
- Supports muscle maintenance and recovery
- Promotes satiety, aiding in weight control
- High in branched-chain amino acids (BCAAs)
- Ideal for overnight muscle support
Sources:
Found in milk and dairy products; extracted during cheese production.
Observations:
Often used in protein powders and meal replacement shakes. Best taken at night or between meals. Not suitable for individuals with dairy allergies. Excessive intake may cause digestive discomfort in lactose-intolerant individuals.
