Supplement
Milk protein is the protein portion of milk, mostly casein and whey, which supplies the amino acids the body uses to build and repair tissues. People with type 2 diabetes often look at it for blood sugar, and a review of controlled meal trials found mixed results, with moderate evidence overall. Blood pressure improved slightly in that group, while appetite showed no clear difference in a tiny weight-loss study of 17 people.
