Vitamin D3 most effective
The most common forms of vitamin D (calciferol) are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Ergocalciferol is a plant-based form, while cholecalciferol is derived from an animal source, but is also produced by the human skin under the influence of ultraviolet light, such as the sun (hence the nickname ‘sunshine vitamin’). These forms of vitamin D are converted in the liver into the metabolite calcidiol (25-hydroxyvitamin D). Calcidiol is converted as needed in the kidneys and other cells and tissues into the biologically active hormone calcitriol (1,25-dihydroxyvitamin D). In terms of supplementation, it is important to know that vitamin D3 generally appears to be more effective than vitamin D2 in raising calcidiol in the blood and ultimately calcitriol.

Vitamin D requirements
Vitamin D can be produced in the skin, but for many in the Netherlands, this is not easily achieved. This requires being outside for at least 15 to 30 minutes every day between 11 am and 3 pm. Many people have jobs that prevent them from being outdoors during these hours. Furthermore, the weather can often be unfavourable. And when people do expose their skin to the sun, they tend to apply sunscreen quickly. Moreover, the sun is not strong enough from November to May. Most people do not produce enough vitamin D during these months and do not get sufficient amounts from their diet. Many vitamin D experts also believe that the optimal vitamin D level is higher than what is indicated in regular guidelines. They suggest that the calcidiol level should be at least 75 nanomoles per litre of blood (nmol/l) for everyone, while the Health Council considers 30 nmol/l (or 50 nmol/l from age 70) to be sufficient. The dietary standards and supplementation advice for vitamin D are based on this.

- is important for calcium and phosphorus absorption to maintain strong bones and teeth
- beneficial for muscles
- contributes to the process of cell renewal
- supports the body's immune system
