Can non-chelated forms of minerals work?
Yes, to a lesser degree, how much less depending on the form. Take calcium for example. 500mg of calcium carbonate nets about 50mg of actual calcium, of which only about 5 to 10 mg of calcium will make it into the system (assuming everything else is correct). Whereas, 50 mg of calcium as calcium citrate chelate nets the same 50mg of actual calcium (as above), but offers 40 to 48mg of actual calcium to the body in a form the body can actually use easily.
