Casein
ProteinKey Benefits
How It Works
Casein forms a gel in the stomach, resulting in slow, sustained amino acid release over 6-8 hours. This makes it ideal for overnight muscle protein synthesis. Micellar casein retains its natural structure for slowest digestion.
Dosage & Timing
Recommended Dosage
20-40 g per serving
Best Time to Take
Before bed (primary use), or between meals for sustained protein
Recommended Form
Micellar casein (not calcium caseinate)
Side Effects
GI discomfort, bloating. Dairy allergy/sensitivity. Slower digesting may cause fullness.
Drug Interactions
Similar to whey. May affect drug absorption if taken simultaneously.
What Does The Research Say?
Research supports overnight muscle protein synthesis when taken before bed. Less insulinogenic than whey. Combination of whey + casein may be optimal for total daily muscle protein synthesis.
