Vitamin D3 3000 IU, 100 softgel capsules

Cholecalciferol - the most effective form of vitamin D

High doses of vitamin D have been known in the orthomolecular world for some time. In recent years, however, a large number of clear research findings have led more and more (respected) experts (scientists, professors and physicians) to urgently recommend vitamin D supplementation.

This product contains 75 µg vitamin D3 (cholecalciferol), measured as 3000 IU (international units), derived from sheep lanolin. The softgel capsules with vitamin D3 (3000 IU) provide a high-dose supplement to support your own production through sunlight and dietary intake. It is best to have your vitamin D levels measured and to adjust the dosage according to the blood values.

The effect of vitamin D3 is the most pronounced.

The most common forms of vitamin D (calciferol) are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Under the influence of UV light, as emitted by the sun, the human body produces cholecalciferol in the skin (which is why it is also called the “sunshine vitamin”). In the liver these forms of vitamin D are converted into calcidiol (25-hydroxyvitamin D), a metabolite. In the kidneys as well as in other cells and tissues, calcidiol is converted into the biologically active hormone calcitriol (1,25-dihydroxyvitamin D) as required. Regarding supplementation, it is important to note that vitamin D3 appears in most cases to be more effective than vitamin D2 at raising calcidiol and ultimately calcitriol levels in the blood.

Vitamin D requirements

Although the skin can produce vitamin D, this does not work properly for many Europeans. It is necessary to spend at least 15 to 30 minutes outdoors daily between 11:00 and 15:00. Many people have jobs that keep them indoors precisely at these times. The weather is also often unfavourable. If people then go into the sun with uncovered skin, their skin is soon treated with sunscreen. Moreover, the sun’s intensity is insufficient between November and May. Therefore vitamin D production and intake via food is insufficient for most people (especially in these months). Many vitamin D experts also hold the view that the optimal vitamin D level is higher than stated in common recommendations. In their view, the calcidiol level in every person should be at least 75 nanomoles per litre of blood (nmol/l), whereas, for example, the Dutch Health Council considers a value of 30 nmol/l (or 50 nmol/l from age 70) to be sufficient. This forms the basis for the reference values for nutrition and the recommendations for vitamin D supplementation.

The effects of vitamin D in the body

Over recent decades knowledge about the role and importance of vitamin D in the human body has grown considerably. Researchers have discovered vitamin D receptors in more than 30 different tissues and organs, including immune cells, muscles and bones. This means that vitamin D has a wide range of effects and promotes health in many ways. Above all, it is known that vitamin D is beneficial for teeth and bones. Vitamin D is necessary for the absorption/utilisation of calcium and phosphorus from the diet and for maintaining normal blood levels of these two nutrients. These minerals are in turn necessary for the mineralisation of teeth and bones. Vitamin D is also beneficial for muscles, as a vitamin D receptor is present in muscle tissue. Its activation increases protein production in the muscles, which is essential for their function. Furthermore, vitamin D plays a role in the cell division process and in the formation of new cells and tissues. In addition, vitamin D has an immunomodulatory effect, meaning it regulates processes within the immune system. Vitamin D receptors are present on T helper cells, a type of white blood cell that plays a crucial role in certain immunological processes. In this way vitamin D plays a diverse role in our complex immune system.
