Vitamin D

GNC Vitamin D 400, Tablets

Vitamin D is a fat-soluble vitamin that regulates the formation of bone and the absorption of calcium and phosphorus from the intestine. It helps to control the movement of calcium between bone and blood, and vice versa. It is this vitamin you need for strong bones and teeth. In addition it helps your body absorb the amount of calcium it needs.

Vitamin D can be found in fish liver oil, egg yolks, milk and other dairy products fortified with vitamin D. It is also produced in our body in the presence of ultra violet light and sunlight.

The deficiency of vitamin D can cause weak bones and bowed legs (in children). And its excess can cause loss of appetite, weight loss, nausea, headache, depression and deposits of calcium in the kidneys.
