Casein Protein

MODERATE EVIDENCEAmino AcidLast updated

AVELOR SUMMARY

Casein makes up 80% of milk protein (whey is the other 20%) and is the "slow protein" — it forms a gel (clot) in the stomach that digests over 5-7 hours vs whey's 1-2 hours. Our research shows this sustained amino acid delivery makes casein SUPERIOR to whey for anti-catabolic (muscle preservation) purposes but INFERIOR for acute muscle protein synthesis stimulation. The landmark Boirie 1997 study showed casein suppressed whole-body protein breakdown by 34% while whey stimulated synthesis by 68% — they're complementary, not competing. Micellar casein is the intact native form; casein hydrolysate (PeptoPro®) digests fast like whey, defeating the purpose.

WHAT IT DOES

Micellar casein's unique property is pH-dependent gelation: at stomach pH (1.5-4), casein micelles aggregate into a semi-solid clot (the same chemistry that makes cheese). This clot digests slowly via pepsin, releasing amino acids over 5-7 hours. The sustained aminoacidemia maintains elevated blood leucine above the muscle protein synthesis threshold for much longer than whey (which spikes and crashes in 1-2 hours). For overnight recovery: pre-sleep casein provides amino acids throughout the 7-8 hour fasting period of sleep, preventing the catabolic state that occurs when blood amino acids drop below the synthesis threshold.

OPTIMAL DOSAGE

Look for: Micellar casein (NOT caseinate, NOT hydrolysate); cold-processed; A2 casein if GI-sensitive; 20-25g protein per serving; third-party tested
Avoid: Sodium/calcium caseinate (acid-processed, denatured — loses slow-digestion property); casein hydrolysate (fast-digesting); products with excessive fillers/sweeteners
Minimum effective dose: 20g pre-bed for overnight recovery
Third-party tested brands: Optimum Nutrition (Gold Standard Casein), Dymatize, Legion (Casein+)
