The sunshine supplement

At this time of year, taking a high dose vitamin D3 (cholecalciferol) supplement - such as Vita-D3 - can prevent the effects of severe deficiency particularly in children and the elderly.  Being indoors for much of the winter is thought to be responsible for 1 in 6 people having a severe deficiency which can affect the structure and strength of the bones. Vitamin D deficiency can be caused by taking certain medicines and also affects sufferers of Crohn's and coeliac diseases.

Vita-D3 is a supplement containing 1000 IU of vitamin D3 per tablet. It is easy to take and is one of the best ways of providing the body with the optimum daily dose of vitamin D.

The main action of Vitamin D is to aid the absorption in the gut of calcium and phosphorous in the diet, essential for maintaining a healthy immune system, strong bones and teeth.

Also known as the 'sunshine vitamin', a 20-minute daily dose of sunlight is usually all it takes for the body to replenish its supply of vitamin D. People with pigmented skin and those who use high sun protection factor creams (SPF 15 and above), may be missing out. Omega-3 rich foods, such as oily fish, egg yolks and fortified spreads and cereals contain some vitamin D but not enough, which is why Vita-D3 is ideal.

Each easy to swallow tablet is free from yeast, soy, gluten and dairy products - ideal for even the most sensitive. The recommended dose is one tablet daily and each pack of Vita-D3 has a four month supply.

Available direct from Forum Health, Vita-D3 is on promotion with a year's supply for just £10.99.
