Vitamin D...

Vitamin D

Vitamin D is a fat-soluble vitamin necessary for the absorption and utilisation of calcium and phosphorus. It is important for the normal growth and development of bones and teeth, and may also help maintain healthy muscles. Vitamin D is important to the immune system

Most of our daily requirements for vitamin D are satisfied by the vitamin D produced in our skin when it is exposed to sunlight. Small amounts may also be taken in through the diet. Natural food sources of vitamin D include oily fish, dairy products, eggs, cod liver oil and milk.

The recommended daily allowance for vitamin D is 5 mcg, but a long-term intake of up to 20 mcg daily is not considered harmful. The form of vitamin D we receive through our diet or supplements is not fully active - it requires conversion by the liver and then the kidney before it becomes fully active
