The Claim

In recreationally active young men, the co-ingestion of 20 grams of milk, whey, or casein protein with 45 grams of carbohydrate following concurrent resistance- and endurance-type exercise results in equivalent activation of mTORC1 signaling pathways, as indicated by similar phosphorylation levels of mTORSer2448, p70S6kThr389, 4E-BP1Thr37/46, and rpS6Ser235/236, suggesting that differences in amino acid kinetics do not lead to differential anabolic signaling under these conditions.

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

If young, active guys drink a shake with 20g of milk, whey, or casein protein plus 45g of carbs after a mixed workout, all three proteins help turn on muscle-building signals just as well—even though they’re absorbed differently.

See the scientific wording

In recreationally active young men, 20 grams of milk, whey, or casein protein co-ingested with 45 grams of carbohydrate after concurrent resistance- and endurance-type exercise activates mTORC1 signaling pathways to a similar extent, as evidenced by equivalent phosphorylation of mTORSer2448, p70S6kThr389, 4E-BP1Thr37/46, and rpS6Ser235/236, indicating that differences in amino acid kinetics do not translate to differential anabolic signaling in this context.

  1. Study: Myofibrillar and Mitochondrial Protein Synthesis Rates Do Not Differ in Young Men Following the Ingestion of Carbohydrate with Milk Protein, Whey, or Micellar Casein after Concurrent Resistance- and Endurance-Type Exercise

    The study found that different types of protein (milk, whey, or casein) with carbs after exercise turn on muscle-building signals in the body just as much as each other.
