Casein is a protein found in milk and dairy products, making up about 80% of the protein in cow’s milk. It’s known for its slow digestion rate, which makes it a popular choice for muscle growth and recovery, especially when consumed before bedtime. Here are some key points about casein:

• Slow Digestion: Casein forms a gel in the stomach, which slows down its digestion and provides a steady release of amino acids.
• Muscle Growth: It’s beneficial for muscle growth and recovery, particularly when taken at night.
• Nutrient-Rich: Casein is a good source of calcium and bioactive peptides.
