Try consuming small amounts of milk with meals. Milk might be better tolerated with food. If you can’t tolerate cow’s milk, try almond, soy or rice milk. Calcium is also in kale, broccoli, tofu sardines and salmon. Some women with lactose intolerance can handle yogurt, so you might want to try it to see how it goes.
Alternatively, you can use an over-the-counter lactase enzyme tablet when eating dairy products. They work naturally to digest lactose inside your gut, giving you the freedom to enjoy the dairy foods you want, when you want. However, I relied more on calcium supplements, as I felt it was hard to reach the recommended pregnancy intake of calcium only through diet.
