 Okay. And then you see people taking Tums and calcium supplements. You know, they buy at the health food store, drug store. Right, right. But these calciums don't absorb in the body. That's interesting. For a couple reasons. One, when you take, let's say, an antacid that has the calcium in it, like a Tums. First of all, calcium does not absorb in the body unless it's in an acidic environment. But see, what happens when you take a Tum? It's an antacid.
