Abstract Abstract: Vitamin D and its hormonally active form, 1,25-(OH)2-D3, stimulate intestinal calcium absorption and may also influence absorption of phosphate and magnesium. Balance studies of 16 healthy and 19 vitamin replete patients eating the same diet were conducted. Net intestinal calcium correlated positively to plasma 1,25-(OH)2-D levels, but phosphate and magnesium absorption did not. In the absence of detectable 1,25-(OH)2-D, significant quantities of phosphate and magnesium were absorbed. In patients with calcium-containing kidney stones, plasma 1,25-(OH)2-D levels were significantly higher than normal, intestinal phosphate absorption was normal, and magnesium absorption was significantly depressed.
