The Claim
In healthy young adults, post-exercise myofibrillar protein synthesis is elevated compared to rest but shows no significant difference between two protein sources when both are provided at 20g within a high-carbohydrate meal, indicating that protein quantity may be a more influential factor than source or meal composition 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.
After exercise, the rate of muscle protein building increases, but this increase is similar whether the protein comes from one source or another, as long as 20 grams are consumed with a high-carbohydrate meal. This suggests that the amount of protein matters more than the type.
See the scientific wording
In healthy young adults, post-exercise myofibrillar protein synthesis increases from rest but remains unchanged between two protein sources when both provide 20g of protein within a high-carbohydrate meal, suggesting that protein quantity may be more critical than source or pairing under these conditions.
After exercise, muscles take in amino acids from the blood, which turn on a molecular switch called mTORC1. This switch tells the muscle cells to start building new muscle proteins using those amino acids. As long as enough amino acids are present, the muscle builds protein at the same rate, no matter where the amino acids came from.
What the research says
1 studyAfter working out, your muscles build protein whether you eat beans and rice or a lab-made mix—as long as both give you 20 grams of protein with lots of carbs. The type of protein didn’t make a difference.
