Dihydrotachysterol is a form of vitamin D. Vitamin D is a fat-soluble vitamin and has properties of both vitamins and minerals. Vitamin D helps you to absorb calcium from what you eat. You need calcium to keep your bones strong, and to help your muscles and nerves work properly.

These agents have antirachitic properties.
Dihydrotachysterol-2 (DHT-2) is a vitamin D2 analog for the Pharmaceutical industry.
