The Claim
In healthy young adults, consuming 30 grams of free amino acids does not result in a greater increase in mixed muscle protein synthesis rates compared to consuming an equivalent amount of intact milk protein during a 6-hour postprandial period, even though plasma amino acid availability is higher with free amino acids.
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.
If you're a healthy young adult, drinking a supplement with 30 grams of broken-down amino acids won't help your muscles grow more than drinking the same amount from real milk protein—even though your body absorbs the amino acids faster.
See the scientific wording
In healthy young adults, ingestion of 30 grams of free amino acids does not increase mixed muscle protein synthesis rates more than an equivalent amount of intact milk protein over a 6-hour postprandial period, despite greater plasma amino acid availability.
What the research says
1 studyThe study found that even though free amino acids led to higher levels of amino acids in the blood, they didn’t build more muscle protein than drinking milk protein in young adults over 6 hours.
