If young, active guys work out and then drink a shake with carbs and protein, it doesn’t help their muscles repair energy factories any better than just drinking carbs alone—within the first 6 hours after exercise.

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

Randomized Controlled Trial

Human

2019 Feb 1

The study found that adding protein to carbs after exercise didn’t help the body make more mitochondria (the energy factories in cells) in young active men, even though it did help build muscle. This matches the claim.

Similar Assertions

For young guys who work out regularly, drinking milk, whey, or casein after a mixed workout doesn’t make a difference in how their muscles rebuild energy parts in the first 6 hours — as long as they also get 45 grams of carbs.

If young guys who work out drink a mix of 20 grams of any milk-based protein and 45 grams of carbs after a workout, their muscles repair themselves about 16% better over the next 6 hours compared to just drinking carbs — and it doesn’t matter which type of dairy protein they use.

If young, healthy guys eat 45 grams of protein before bed after a workout, their muscles build more energy-producing parts overnight compared to skipping the protein.

For young guys who work out regularly, drinking a shake with 20g of any kind of milk protein (like whey or casein) plus 45g of carbs after a combo of strength and cardio exercise helps build muscle just the same — it doesn’t matter which protein they pick.
