Vitamin D3, also known as cholecalciferol, is a steroid organic compound that belongs to the group of fat-soluble vitamins. As a result, its absorption is closely related to the presence of fat in the diet. Vitamin D3 is supplied to the body through food (it can be found, among others, in oily marine fish) as well as through synthesis in the skin. However, it is stored primarily in adipose tissue and the liver.

Vitamin K2, also known as menaquinone, is an organic compound classified as a fat-soluble vitamin. It is stored primarily in the liver. Vitamin K2 can be produced by bacteria naturally present in the digestive tract, obtained through the diet (it is found in both plant- and animal-based foods), or provided in the form of dietary supplements. The vitamin K2 MK-7 used in OstroVit Vitamin D3 4000 IU + K2 is the form best absorbed by the human body. The product also contains vitamin D3, which works synergistically with vitamin K2.
