Regular cow's milk is used to make lactose-free milk. It differs in that the enzyme lactase, which breaks down the lactose in milk, has been added. This makes it simpler to digest and helps prevent the symptoms of lactose intolerance, such as nausea and stomach discomfort.

Hemp and flax milks are higher in heart-healthy unsaturated fats and often contain less calories than cow's milk. Soy milk is likewise higher in heart-healthy unsaturated fats than the other nut milks without added sugar, including almond, walnut, peanut, cashew, hazelnut, and macadamia nut milk.
