If you are lactose intolerant, you may need to avoid or limit dairy products that contain lactose, such as milk, cheese, and ice cream. However, you can still get enough calcium from other dairy products that are low in lactose or lactose-free, such as yogurt, hard cheese or lactose-free milk. You can also get calcium from non-dairy sources. The amount of calcium you need depends on your age and sex. You can refer to the table above for the recommended dietary allowances for calcium.
