“Vitamins are organic substances essential for many life processes. Milk includes fat soluble vitamins A, D, E, and K… Because milk is an important source of dietary vitamin A, fat reduced products which have lost vitamin A with the fat are required to supplement the product with vitamin A.

Milk is also an important source of dietary water soluble vitamins: B1 – thiamine; B2 – riboflavin; B6 – pyridoxine; B12 – cyanocobalamin; niacin; and pantothenic acid…

All 22 minerals considered to be essential to the human diet are present in milk. These include three families of salts: 1. Sodium (Na), Potassium (K), and Chloride (Cl)…; 2. Calcium (Ca), Magnesium (Mg), Inorganic Phosphorous (P(i)), and Citrate in colloidal (nondiffusible) form…; 3. Diffusible salts of Ca, Mg, citrate, and phosphate.”
