Protein supplements might help your muscles refill energy faster after a workout compared to just carbs — but it could just be because they add extra calories, not because protein itself speeds up recovery.

The effectiveness of protein supplements on athletic performance and post-exercise recovery − a Bayesian multilevel meta-analysis of randomized controlled trials

Systematic Review With Meta-Analysis

Human

2026 Dec 31

The study found that protein supplements seemed to help refill energy stores after exercise better than carbs alone, but only when people taking protein also got more total calories. This matches the claim that the benefit might be from extra energy, not the protein itself.

If you eat protein and carbs right after working out, you might recover faster, feel less tired, and refill your energy stores better than if you wait more than 2 hours.

Protein supplements might give athletes a small boost in endurance, especially when taken with carbs—but it could just be because they're eating more calories overall.

Eating carbs after a super-hard workout helps you perform better — but only if you were starving before. If you ate the same number of calories from protein or fat, carbs don’t help any more.

A drink with sugar, a little protein, and a tiny bit of fat after a workout helps muscles recover energy, but not quite as well as a drink with just sugar.

If endurance athletes eat some protein with less-than-ideal carbs after a workout—especially when they have less than a day to recover—it probably helps their muscles refill energy faster and boosts performance a little bit next time.
