Vitamin d absorption, Natural sources of vitamin d

Vitamin D is fat-soluble. It is vital in order for calcium to be absorbed properly into the body, and for the teeth and bones to develop.
Acquired from exposure to sun, food and supplements, vitamin D is biologically inert and needs two hydroxylation reactions in order to be active inside the body.
It also helps fight against osteoporosis, cancer, high blood pressure, and some autoimmune diseases.

Insufficient intake of vitamin D results in thinner bones, misshapen, or brittle.

Deficiency arises from inadequate intake of vitamin D, disorders that place limitations on its absorption, inadequate sunlight exposure, conditions that cause vitamin D conversion impairment, such as kidney or liver disorders, or a number of rare hereditary disorders.
