Vitamin D3 1000 IU, 100 capsules

Cholecalciferol vegan - 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 results have led to more and more (respected) experts (scientists, professors and doctors) urgently recommending vitamin D supplementation.

This product contains 25 µg of vitamin D3 (cholecalciferol), which corresponds to 1000 IU (international units). Plant-based vitamin D3 (vitamin D3V®) is also used. This is due to the fact that it is made from algae and not from sheep's wool fat (like most vitamin D3 products). This means that the capsules with 1000 IU vitamin D3 are now also suitable for vegans. Vitamin D3 1000 IU provides a high supplementation dose to supplement the body's own production from sunlight and food intake. It is best to have your vitamin D level measured and adjust the dosage according to your blood values.

The effect of vitamin D3 is most pronounced.

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

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 a day outdoors between 11am and 3pm. While many people have a job that requires them to be indoors at these times. Also, the weather is often not favourable, so if people go out in the sun with uncovered skin, their skin will soon be treated with sun cream. In addition, the sun's power is not sufficient between November and May. As a result, vitamin D production and intake through food is insufficient for most people (especially during these months). Many vitamin D experts also believe that the optimum vitamin D level is higher than the current recommendations. In their view, everyone's calcidiol level should be at least 75 nanomoles per litre of blood (nmol/l), while the Dutch Health Council, for example, considers a level of 30 nmol/l (or 50 nmol/l from the age of 70) to be sufficient. The reference values for nutrition and the recommendations for vitamin D supplements are based on this.

The effect of vitamin D in the organism

In recent decades, knowledge about the role and importance of vitamin D in the human body has increased considerably. Researchers have discovered receptors for vitamin D in over 30 different tissues and organs, including immune cells, muscles and bones. This means that vitamin D has a variety of effects and promotes health in many different ways. Above all, it is known that vitamin D is good for teeth and bones. Vitamin D is necessary for the absorption of calcium and phosphorus 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 the muscles, as a vitamin D receptor is also present in muscle tissue. Its activation increases protein production in the muscles, which is essential for their function. Vitamin D also plays a role in the cell division process and in the formation of new cells and tissues. Vitamin D also has an immunomodulatory effect, i.e. it regulates processes within the immune system. Vitamin D receptors are found on T helper cells, a type of white blood cell that plays a decisive role in certain immunological processes. In this way, vitamin D plays a multifaceted role in our complex immune system.
