New problems in relation to the possible function of vitamin D in promoting bodily welfare continue to arise, despite the commendable progress of recent years. One concerns the uncertainty of the need of supplementing the diet with added vitamin D if it is liberally supplied with the appropriate mineral constituents, notably calcium and phosphorus. As long as there is a widespread impression of a possible shortage of the bone-forming elements under the current dietary regimens in this country, as Bernheim1 has recently intimated, the effort to alter prevailing conditions will naturally persist. She ventures the assertion that general health is improved and recovery from disease aided when the optimum calcium supply and utilization are assured. Furthermore, Bernheim insists that utilization of calcium is ineffectual, even with a sufficient calcium intake, unless also the factors that control the absorption of calcium are adequate.
