Super Natural Calcium can restore calcium nutrition in a form human biochemistry recognizes and utilizes. The mineral is needed by all humans, at all times, at all age levels. However, calcium supplementation becomes a focus for women after age 30 and for men after age 40, the demarcation points where population studies tell us we slip into negative calcium balance (i.e. the loss of more calcium through the urine than is absorbed by the GI tract.). We expect, therefore, that adults will be especially interested in Super Natural Calcium.
