The Claim
Pure protein supplements are likely associated with improved glycogen resynthesis after exercise compared to carbohydrate-only supplements, with a standardized mean difference of 0.83, but this effect is only observed in studies where total energy intake was not matched, suggesting that the observed benefit may be due to greater caloric availability rather than a specific metabolic role of protein in recovery.
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.
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.

What the research says
1 studyThe 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.
