Lots of them.

First, is Lactaid milk, which has the lactose-digesting enzyme lactase added to it. I believe you can purchase lactase separately and that it can be taken with lactose foods to aid in digestion.

Second is yogurt or kefir, a fermented dairy drink that has much lower lactose content due to the active bacteria. But you should check, since they're not lactose free.

The harder the cheese, the less lactase it has, so you might be okay with hard aged cheddars, parmesans, goudas, etc. over younger, creamier types.

Almond milk has calcium. As do almonds. So does broccoli, spinach, and other dark greens. A good spring mix salad is surprisingly high.

There are obviously plenty of calcium supplements you can purchase if you're concerned. Anecdotally (meaning I read it somewhere), look out for too much phosphoric acid, a common acidic ingredient in soda, because it's been accused of interfering with calcium absorption.

Just for curiosity, my friend growing up cured his lactose intolerance by drinking small amounts of milk every day until he "graduated" to a full glass. He didn't have a problem after that.

Almond milk has calcium. As do almonds. Soymilk is well fortified.
