Secondary Calcium Phosphate Prevents and Cures Rickets Without Vitamin D. 2. Calcification Studies

Abstract

Conclusions

The substitution of refined dicalcium phosphate or unrefined dicalcium phosphate for calcium carbonate in the ricketsproducing diet resulted in the prevention and cure of rickets. Disregarding the effect of an external supply of phosphorus in the diet, these experiments indicate that from the standpoint of bone formation, refined dicalcium phosphate or unrefined dicalcium phosphate are infinitely superior to calcium carbonate in its various forms, such as precipitated chalk, crushed limestone, or crushed shells. Hence it is proper to refer to refined and unrefined dicalcium phosphate as being indicated in cases of rickets, or leg weakness of chicks.
