What is the standard casein protein dose?
Casein, a slow-digesting milk protein used in supplements for muscle recovery and satiety, typically carries a recommended dose of 20-40 grams per serving. This amount provides 15-30 grams of protein, depending on the product's concentration (often 75-90% protein by weight). Manufacturers like Optimum Nutrition or BSN suggest mixing one scoop (around 30g) with water or milk, taken once or twice daily.[1]
How much casein before bed?
The most common timing is 30-40 grams about 30 minutes before sleep. Its slow release (up to 7-8 hours) supplies amino acids overnight, supporting muscle repair during fasting. Studies show 40g increases overnight protein synthesis by 22% compared to placebo.[2][3]
Casein dose for weight loss or meal replacement
For appetite control or as a meal replacement, 20-30 grams per serving works, often combined with fiber-rich foods. Doses up to 50g daily split across meals reduce hunger hormones like ghrelin, but exceeding 1.6g protein per kg bodyweight total daily offers no extra benefit.[4]
How does whey compare to casein dosing?
Whey (fast-digesting) uses similar 20-40g doses but for post-workout (within 30-60 minutes). Casein suits pre-bed or between meals; blending 50/50 (20g each) covers both absorption profiles. Total daily protein from both should hit 1.6-2.2g/kg bodyweight for athletes.[5]
Risks of high casein doses or who should avoid it?
Over 40-60g per dose risks digestive upset like bloating in lactose-sensitive people (casein is often low-lactose micellar form). Kidney patients limit to 0.8g/kg total protein daily. No major toxicity up to 3g/kg, but consult a doctor if pregnant or on meds.[6]
