BLG vs Whey: Same Muscle Growth, Better Amino Absorption
The Effect of Leucine-Enriched β-Lactoglobulin Versus an Isonitrogenous Whey Protein Isolate on Skeletal Muscle Protein Anabolism in Young Healthy Males

BLG has more leucine, but both proteins build muscle equally well in young men.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Young men who drank a β-lactoglobulin protein shake had higher blood leucine levels over time than those who drank regular whey protein, but their muscles built protein at the same rate.
When young men consumed β-lactoglobulin, their blood leucine levels peaked higher than when they consumed regular whey protein.
Young men who drank β-lactoglobulin had higher levels of branched-chain and essential amino acids in their blood over time compared to those who drank regular whey protein.
Both types of protein shakes boosted muscle protein building similarly in young men, whether they were resting or exercising after drinking them.
Even though these protein shakes had less amino acids than previously thought necessary, they still effectively boosted muscle protein building in young men.
