Is cow milk the same as whole milk?

Vitamins are measured in "international units."

RAW MILK contains approximately 40 IU (international units) per liter. Pasteurized, fortified, reduced fat milk, specifically 2% milk, contains about 105 IU a cup -- which works out to a little over 443 IU every liter.
