100% Casein (908g)
Casein protein is a slow-digesting dairy protein that is found in milk, making up about 80% of the protein in cow's milk. It is highly valued for its ability to provide a sustained release of amino acids over several hours, which can be beneficial for muscle repair and growth, particularly during periods of fasting or sleep.
Key characteristics of casein protein:
-
Slow absorption: Casein forms a gel-like substance in the stomach, leading to slower digestion and a more gradual release of amino acids. This contrasts with whey protein, another milk-based protein, which is absorbed more quickly.
-
Rich in amino acids: Like other animal-based proteins, casein is a complete protein, meaning it contains all nine essential amino acids necessary for muscle growth and repair.
-
Muscle recovery: Due to its slow release of amino acids, casein is often used by athletes or bodybuilders before bedtime to promote overnight muscle recovery.
-
Types of casein protein:
- Micellar casein: The most common form found in supplements, micellar casein is the natural form of casein that digests slowly.
- Casein hydrolysate: This type has been pre-digested to break it down into smaller peptides, resulting in faster absorption, though it is still slower than whey.
-
Benefits:
- Muscle maintenance: Because of the extended release of amino acids, casein helps reduce muscle breakdown, making it popular for maintaining muscle mass during periods of calorie restriction.
- Satiety: Its slow-digesting nature helps promote a feeling of fullness, which can be useful for weight management.
-
Food sources: Casein is naturally found in dairy products like milk, yogurt, cheese, and cottage cheese.
In the supplement world, casein is often marketed as an option for nighttime protein intake, complementing faster-digesting proteins like whey, which are better suited for post-workout recovery.
