@catstx I have been lactose intolerant for about 2 years or so. I never found Lactaid tablets to help but I have gotten some help from Digestive Advantage, Lactose Defense formula. Even with that though I could not have things that @astaingegerdm mentions, like regular ice cream and pizza.

I also have no trouble with any aged cheeses, they only have a very small trace of lactose in them, it drops out in aging. The lactose is actually in the whey. Just remember though, if you eat a lot of anything that has a non-measurable trace, those traces can add up and cause a problem. As I said above, I cannot eat regular pizza so I have taken to making my own and I use provolone cheese. We actually like it more than we like it with mozzarella, it's more flavorful. There is also a pizza with no cheese, Amy's vegetable pizza. I have purchased that too and added my own aged cheese before baking.
As mentioned, Whole Foods does have some good lactose free dairy products under the name of Green Valley. There is also a yogurt brand that used to be carried by a store around here. It was Good Belly I believe.

I have changed to Fairlife milk. It's free of lactose, has high calcium, and high protein! It tastes good too.

The thing I miss most is Caprese salads, they of course have fresh mozzarella in them. I also miss Italian foods that have ricotta, like lasagna.
