What is vitamin d?

Vitamin D belongs to the group of calciferols, which is a collective term for various substances of this type. Calciferols can be taken in active or inactive form through food. However, your body is also capable of forming a precursor itself: this happens in the liver and in the intestinal mucosa. Your skin needs sunlight to activate the precursors. Activation then produces vitamin D, which is important and effective for you. It is therefore important that you regularly expose your skin to the sun in order to activate the vitamin D on your skin under the influence of UV light.
