Vitamin D

Vitamin D supplements are often taken by people in northern areas who may not get much sun exposure; this is because people get most of their vitamin D intake from the sun's ultraviolet rays. You can find vitamin D products from Holland & Barrett in the Vitamin D section of this website.

What is Vitamin D?

Vitamin D is a fat-soluble vitamin used by the body for a number of important functions. The most recognised use of vitamin D is its role of assisting with the maintenance of bone health along with calcium. There are two forms of vitamin D; these are Ergocalciferol (vitamin D2), and Cholecalciferol (vitamin D3).

Vitamin D Intake

Aside from the sun's ultraviolet rays, there are a number of other ways to get your daily intake of vitamin D. These include cod liver oil, nuts, and some fortified cereals and milk. The daily recommended intake of vitamin D varies for people of different ages.

With age the body may not convert the vitamin D from sunlight as easily, so some older people may have a higher recommended intake, which can be satisfied with vitamin D supplements. Other factors exist that may make it harder to acquire vitamin D from the sun, including: clouds, smog, clothing, sunscreen, and window glass.

Vitamin D supplements can be found in tablet, capsule, and liquid form.

Vitamin D Functions

Getting your daily intake of vitamin D is essential for several of the body's functions. Vitamin D is known to contribute to the normal function of the immune system, whilst also playing a role in maintaining normal muscle function.

As mentioned, vitamin D also contributes to the maintenance of bone health, as it is used to support the absorption and utilisation of calcium and phosphorus.
