Vitamin D (Cholecalciferol)
General description
The term vitamin D is used to describe two substances from two different
sources. Vitamin D-3, cholecalciferol, is formed from cholesterol and is
synthesized in the body during exposure to ultraviolet light (e.g. sunlight). The
other substance is vitamin D-2, ergocalciferol, which is found in plants and is
used to fortify foods such as margarine, cereals, and milk. Both substances
perform the same function in the body.
Health applications
Bone health
Aids calcium absorption
Skin health
Functions and uses
Vitamin D (cholecalciferol and ergocalciferol) promotes intestinal absorption of
calcium and phosphate into the blood stream. It also frees calcium from bones
for use in other parts of the body. It is essential for normal bone growth and
development. It also works in the kidneys to prevent calcium and phosphate
loss through urine. Both forms of vitamin D are converted by the body into an
active form called calcitriol. The liver and kidneys are involved in this process.
For this reason, kidney failure often results in calcium deficiency symptoms.
Dosage and toxicity
Vitamin D is available in many multivitamin formulas. The RDI is 400 IU of
vitamin D daily. This recommendation does not take into account the fact that
people may be producing sufficient amounts of the vitamin due to exposure to
the sun. It can be toxic if taken in doses larger than 400 IU. Symptoms of
toxicity are headache, nausea, vomiting, metal taste in the mouth, fatigue, and
muscle and bone pains. In addition, excess vitamin D can lead to an
accumulation of calcium in vital organs, such as the liver and kidneys, with
potentially dangerous consequences.
