Milk and other dairy products are not prohibited for young women with PCOS. If you find that dairy upsets your stomach, you may want to try a different type of milk to get the important nutrients that milk provides. However, not all milk alternatives are created equally. When finding an alternative to milk you want to make sure that the product has around the same amount of calcium (300 mg) and protein (8 grams) as one glass of dairy milk. Lactaid is a type of dairy milk that has the lactose removed. Soy milk is a non-dairy source of milk made from beans that has similar amounts of calcium and protein. Beware of nut milks such as almond milk; these have calcium (though it is added, not naturally occurring) but very little protein.
