Karuna Health D-1000 was thought to have a singular function, to help maintain serum calcium levels by facilitating intestinal calcium absorption and helping to regulate renal excretion and bone remodeling.
Modest amounts of vitamin D were known to be adequate to prevent low calcium levels and acute bone loss diseases such as rickets and osteomalacia.
Today, not only are adequate levels of vitamin D intake for optimum bone protection being revised sharply upward.
