Roles Classification
Biological Role(s): fat-soluble vitamin (role)
Any vitamin that dissolves in fats and are stored in body tissues. Unlike the water-soluble vitamins, they are stored in the body for long periods of time and generally pose a greater risk for toxicity when consumed in excess.
(via vitamin D )
Application(s): bone density conservation agent
An agent that inhibits bone resorption and/or favor bone mineralization and bone regeneration. Used to heal bone fractures and to treat bone diseases such as osteopenia and osteoporosis.
