The following graph shows a typical dairy milk protein amino acid profile. It’s basically the combination of whey and casein, all in one.
This graph was generated using our amino acid profile comparison tool.
Here’s the data in table form if you prefer. Essential amino acids are marked with an asterisk (*).

Overall Summary of Milk Protein’s Amino Acid Profile
Dairy milk is a complete protein, as you’d probably expect.
That being said, it is relatively low on both Cystine and Tryptophan, with the second being an essential amino acid.
So while it’s a good protein source (from a nutritional standpoint), there’s nothing particularly special about it either. It’s less balanced than the amino acid profiles of eggs or whey, or even plant protein sources like hemp protein.
