House of Hypertrophy

For healthy guys, drinking regular milk protein gives your body more usable protein building blocks over 5 hours than taking just whey or just casein alone.

Quantitative

As men get older, their bodies don't absorb protein from food as well after eating — specifically, older guys get less use out of the amino acids from a protein meal compared to younger guys.

Quantitative

When healthy guys drink milk protein, about half of the protein gets into their bloodstream within 5 hours — that's what muscles can use. The rest is either still being digested or gets used by organs like the liver before it ever reaches the rest of the body.

Quantitative

It's not just how fast amino acids show up in your blood after eating — it's how much your body gets over time that might matter more for building muscle.

Mechanistic

When healthy guys drink more whey protein, their bodies absorb more of an important amino acid called phenylalanine—about 10% more when they take a higher dose.

Causal

If healthy guys drink more casein protein, more amino acids show up in their blood overall—even though a smaller percentage gets absorbed—probably because their bodies haven’t finished digesting it within 5 hours.
