✓ What the Science Says
Casein is a slow-digesting dairy protein that provides a sustained release of amino acids, making it beneficial for muscle repair and growth, particularly when consumed before sleep. It has been shown to improve muscle mass and strength gains when combined with resistance training.
✗ What It Doesn't Do
Casein is not a miracle weight loss solution; while it may aid in muscle preservation during dieting, it does not directly cause fat loss. Additionally, claims that it can replace whole meals or drastically enhance athletic performance without a balanced diet are misleading.
