Milk's calcium absorbtion rate isn't the best (about 32%)--I like to try for good veggie sources of calcium more; a lot of vegetables have about a 50% absorbtion rate...your body retains it better, too... try dark green leafy veg (mustard greens, kale--spinach has a lot of calcium, but you can't absorb it that well), broccoli, beans, bean sprouts.

I *think* the US RDA is 1,000 mg...found one sourse that says that so far, but it's selling vitamins, so I don't know if it's correct I'll come back and let you know if that turns out to be wrong.

Milk is the best for you.
