The Claim

In active older men participating in resistance training, daily muscle protein synthesis rates do not differ between those consuming a protein supplement containing 21g of protein and 3g of leucine after exercise and before sleep and those consuming an energy-matched placebo, indicating that the supplement does not further enhance molecular-level muscle building under these conditions.

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.

How it works
1 study reviewed
In plain English

Older guys who lift weights and take a protein shake after workouts and before bed get the same muscle-building effect as those who take a fake shake with the same calories — so the protein might not actually help at the molecular level.

See the scientific wording

In active older men undergoing resistance training, daily muscle protein synthesis rates are similar whether consuming a protein supplement (21g protein, 3g leucine) after exercise and before sleep or an energy-matched placebo, suggesting that such supplementation does not further stimulate muscle building at the molecular level.

What the research says

1 study
  1. Study: Protein Supplementation after Exercise and before Sleep Does Not Further Augment Muscle Mass and Strength Gains during Resistance Exercise Training in Active Older Men.

    The study found that older men who exercised and took a protein supplement didn’t build more muscle at the molecular level than those who took a fake supplement with the same calories. This matches the claim that the protein didn’t help extra muscle building.
