The Claim

Ingestion of leucine-enriched essential amino acids and carbohydrates after resistance exercise in young men enhances the phosphorylation of mTOR at Ser2448 and its downstream targets S6K1 and 4E-BP1 compared to resistance exercise alone.

Source: Leucine-enriched essential amino acid and carbohydrate ingestion following resistance exercise enhances mTOR signaling and protein synthesis in human muscle.

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

After working out, drinking a special protein and sugar shake helps your muscles start building more efficiently by turning on key signals inside your muscle cells, better than just working out alone.

See the scientific wording

Leucine-enriched essential amino acids and carbohydrate ingestion after resistance exercise in young men enhances phosphorylation of mTOR at Ser2448 and its downstream targets S6K1 and 4E-BP1, which are key regulators of muscle protein translation initiation, compared to resistance exercise alone.

Why this might work

After a workout, drinking a mix of special proteins and sugar causes leucine to enter muscle cells and turn on a key signaling system that tells the cell to start making more muscle proteins. The sugar triggers insulin, which helps remove a brake on this system, while leucine directly activates another part of it. Once the brake is off and the signal is on, a master regulator called mTOR gets turned on, which then activates two other proteins that help the cell read its protein-building instructions more efficiently, leading to more muscle protein being made.
