The Claim
In young, recreationally active males undergoing supervised resistance training four times per week for 10 weeks, consuming 35 grams of casein protein either 3 or more hours before sleep or earlier in the day (at least 3 hours removed from exercise and sleep) leads to comparable increases in lean soft tissue mass, muscle cross-sectional area, and strength, provided that total daily protein intake is matched at approximately 1.8 g/kg body weight and diets are isocaloric.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If young, active guys lift weights 4 days a week and eat the same total amount of protein, it doesn’t matter whether they have their casein protein late at night or earlier in the day — they’ll gain similar muscle and strength over 10 weeks.

What the research says
1 studyThe study found that taking casein protein either during the day or before bed worked equally well for building muscle and strength when total protein and calories were the same.
