Hardly a week goes by without the publication of at least one new scientific study showing the benefits - or dangers of deficiency - of vitamin D.
Normally, more than 90 % of our vitamin D needs are met through exposure to the sun. But during the winter months, vitamin D production decreases and varying degrees of deficiency can appear.

¤ Vitamin D has long been considered essential for healthy bones. But scientists have shown that it also plays a key role in cell division and differentiation and that it has an effect on the immune system.

¤ In fact, inadequate levels of vitamin D are linked with almost all age-related problems, including cancer, vascular disease and chronic inflammation. Adults with higher vitamin D levels suffer less from colds, ‘flu and other infections.

¤ And yet, inadequate intake is all too frequent: among Western populations in countries such as France, Belgium, the United States, Switzerland and Canada, vitamin D levels are far too low, particularly during the winter months.

¤ In most of the developed world, official recommended daily amounts are insufficient to provide health protection. This was actually acknowledged in 2007 by 15 researchers, biochemists, doctors, epidemiologists and public health specialists who criticized such recommendations that were leading to marked deficiencies of vitamin D among Northern hemisphere populations. These experts estimate we need closer to 1000 IU vitamin D a day.

¤ At the beginning of 2010, 40 international scientists launched an appeal to increase doctors' awareness of the importance of vitamin D in preventing osteoporosis, heart disease and cancer. In their view, supplementation with 1000-2000 IU a day should be recommended for the general population, particularly during autumn and winter, in order to meet needs for vitamin D.

¤ Research suggests that a daily dose of 5000 IU of vitamin D may provide multiple health benefits. It is also the dose recommended by the vitamin D council. Studies have also shown that up to 10,000 IU a day of vitamin D3 can be taken without risk.

adults. Take one tablet a day or as advised by your therapist.
Warning : At doses above 2000 IU a day, a 25-hydroxyl vitamin D analysis should be carried out. If you suffer from kidney disease, do not take vitamin D3 without consulting your therapist. Do not exceed 10,000 IU a day, all sources combined, without the advice of your therapist.
