Micro Fine Calcium Supplement with High Levels of Vitamin D. For species with high Vitamin D requirements, receiving little UVB radiation from natural or artificial sunlight. Also for therapeutic use. INFORMATION: Our Calcium Carbonate is mined from the Mohave Desert in California, where it was deposited 300 million years ago during the Mississippian Age as a large graveyard of marine animals. It was formed in very favorable conditions in a shallow marine environ-ment. These remains were cemented together with Cal-cium Carbonate precipitated out of the primordial sea. The deposit was then further purified and metamorphosed by various natural geologic processes including high pressure and temperature. This deposit is an extremely pure source of natural Calcium Carbonate which makes it a truly unique source for food, supplement, and pharma-ceutical applications. It is FDA Food Grade Certified. Our calcium is micro ground to an average size of 3.5 microns, and is the finest available grind on the market, which provides the ultimate stick when dusted onto insects.
