Expert studies show that it is advisable to combine vitamin D3 with vitamin K2.

The Czech population suffers from a lack of vitamin D. It is essential for the normal function of the immune system (1). Very few foods naturally contain or are enriched with vitamin D. People obtain it from exposure to sunlight, from a diet rich in fatty fish, or from medications and food supplements. It is estimated that up to 1 billion people worldwide may be vitamin D deficient. That is why it is absolutely necessary to supplement vitamin D either in a natural, natural form - the sun, fish, but also in an artificial form, i.e. medications and specialized food supplements.

Vitamin D deficiency mainly affects a large part of the elderly population, especially women who live in countries with a temperate climate, due to a reduced amount of vitamin D in the diet (the source is mainly the consumption of oily marine fish). The lowest seasonal concentration of the active form of vitamin D is usually observed during winter and spring. It is particularly alarming that more than 50% of post-menopausal women taking osteoporosis drugs have insufficient values ​​of the active form of vitamin D3 in their blood, as e.g. Boston University study (2). A study of outpatients in Denver showed vitamin D deficiency in even 74% of seniors aged 66-89 (3).

Vitamin K2 is an expensive substance, but research shows that it is very important for the human body (4), especially for maintaining the normal state of bones. Its source in food is mainly beef, yogurt and soft cheeses. However, its intake in a typical Central European diet may not be sufficient. Some of the vitamin K2 is also produced by bacteria naturally present in the human gut. However, their activity can be weakened in case of frequent use of antibiotics.

A number of studies (5-9) show that there are synergistic (mutually reinforcing) effects of the simultaneous administration of vitamins D and K.
