Vitamin D

Vitamin D and nutritional therapy

Vitamin D is fast becoming known as a “super-nutrient”. As well as being a important nutrient for healthy bones, research is now showing that deficiency can be linked to a wide range of health problems.

Functions of Vitamin D;

• Maintenance of normal bones • Maintenance of normal muscle function • Normal function of the immune system • Cell division • Normal utilisation of calcium

Where to source Vitamin D

Very few foods naturally contain vitamin D, so they tend to be fortified such as in, COD LIVER OIL, OILY FISH, FORTIFIED CEREALS, OYSTERS, TOFU, DAIRY, EGGS, MUSHROOMS and MILK. However, this does not provide sufficient Vitamin D on a daily basis. The major source of Vitamin D (80-100%) is SUNSHINE. It is manufactured in the skin on contact with sunshine.

We aren’t getting as much sun as we used to. We work inside, travel in cars and live in cities – all this blocks the sun. In addition to this, skin cancer scares have minimised sun exposure and consequently we use high factor sunscreen.

The result is epidemic proportions of Vitamin D deficiency. Most experts now agree that supplementation is currently the safest and most effective measure of achieving optimal Vitamin D status. Supplements should contain vitamin D in the form of vitamin D3 (cholecalciferol). This is the form naturally produced by the skin upon exposure to sunlight.

Daily recommendations

Even though there is a great degree of individual variation, the general daily dosage guidelines are:

• Children and up to 70 years of age – 800iu per day • Over 70’s – 1000iu per day

It is always advisable to do a test first to check your level and supplement accordingly. Tests can be ordered from:

Your qualified health care practitioner will be able to advise you on the best dose for your individual requirements.
