OstroVit Vitamin D3 4000 IU + K2 – a valuable addition to your daily diet
Vitamin D3, also known as cholecalciferol, is a steroid, fat-soluble vitamin belonging to the group of fat-soluble vitamins. Therefore, the absorption of this ingredient is closely linked to the presence of fats in the daily diet. Vitamin D3 is a substance supplied to the body through food (found, for example, in fatty fish) and through skin synthesis. However, it is primarily stored in adipose tissue and the liver.
Vitamin K2, also known as menaquinone, is a fat-soluble vitamin. Vitamin K2 is primarily stored in the liver within the human organism. It can be produced by bacteria in the digestive tract, supplied to the body through food (found in both plant and animal products), and also in the form of dietary supplements. The K2 vitamin MK-7 used in the OstroVit preparation is the best form for absorption by the human body, which has a positive impact on the quality of the supplement. The product also contains vitamin D3, which works synergistically with vitamin K2 and has a positive effect on the supplement’s efficacy.
