Dr. Holick shares if a woman will receive enough vitamin D per day if she drinks milk.
Milk does contain vitamin D. There’s 100 International Units, and it’s also a very good source of calcium. Eight ounces of skim milk will provide you with about 300 milligrams of calcium and 100 International Units of vitamin D. But we now recognize that people, women in particular, need at least 1500 to 2000 units of vitamin D a day to satisfy their body’s requirement.
So 100 units is a step in the right direction, but you would have to be drinking 15 to 20 glasses of milk a day. So milk is a good source of calcium, and it’s okay for some vitamin D, but you definitely need to get more vitamin D.
