Casein (Slow-Release) Protein

  • -Casein protein powder is known for its slow and sustained digestion rate.
  • -When consumed, it forms a gel in the stomach, leading to a gradual release of amino acids over several hours.
  • -This makes it an ideal protein source for overnight muscle recovery and for preventing muscle breakdown during periods of fasting.
  • -Often referred to as a 'night-time' protein, it is used to promote satiety and support muscle preservation.
