Thus, the assimilation of the ingredient is closely related to the presence of fats in the daily diet. Vitamin D3 is a substance, which is delivered to the body with food (it can be found i.a. in oily sea fish), as well as through skin synthesis. However, it is stored primarily in adipose tissue and liver.<\/p>\n<p><strong>Vitamin K2<\/strong>, referred to as menaquinone, is an organic chemical compound classified as a fat-soluble vitamin. Vitamin K2 is stored in the human body primarily in the liver. It can be produced by bacteria present in the digestive system, delivered to the body with food (it can be found in both plant and animal products), as well as in the form of dietary supplements. Vitamin K2 MK-7 used in the preparation OstroVit is a form of compound that is best absorbed by the human body, which has a positive effect on the quality of the dietary supplement. The product also includes vitamin D3, which works synergistically with vitamin K2, which positively affects the effectiveness of supplementation.<\/p>\n<h3 class=\"cm__heading\">Properties of the ingredients contained in OstroVit Vitamin D3 4000 IU + K2<\/h3>\n<p>Vitamin D present in the product helps to maintain healthy bones and teeth and in the proper functioning of muscles and what is more, it supports the proper functioning of the immune system.
