The Claim

In healthy young men undergoing 12 weeks of resistance training, consuming protein before sleep results in a significantly greater increase in 1-repetition maximum strength (164 ± 11 kg) compared to placebo (130 ± 9 kg), with a statistically significant difference between groups (P < 0.001).

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

If young, healthy guys lift weights for 12 weeks and drink a protein shake before bed, they get way stronger than those who don’t — like 30 more pounds on their lifts.
