Vitamin D

It is a vitamin that dissolves in fats. It comes in three forms:

  • vitamin D1 - calciferol
  • vitamin D2 - ergocalciferol
  • vitamin D3 - cholecalciferol

It is produced in our body when exposed to sunlight for at least 15 minutes a day. In the absence of sunlight, vitamin D3 should be administered in food or in the form of a supplement. Additionally, it is responsible for the absorption of calcium and phosphorus.

Vitamin K

Vitamin K - is a group of chemical compounds derived from 2-methyl-1,4-naphthoquinone. It is produced in the largest amounts by bacteria found in the large intestine. Like vitamins D and E, it is fat-soluble. We can find it in food in broccoli, spinach, cucumber and avocado.


Benefits of taking vitamin K2:

Vitamin K2 maintains and improves bone mineral density. Additionally, it is responsible for transporting calcium to the appropriate places, i.e. to the bones, while preventing its deposition in the arteries. K2 mk7 ensures the appropriate content of MGP proteins, which transport calcium directly to the bones. 

Thanks to activation, GLP proteins produced by bone-forming osteoblasts - most often occur where the growth or reconstruction of bone tissue takes place. Thanks to this, increasing the level of K2 mk7 contributes to faster bone regeneration after injuries and proper bone development in children and adolescents. Another important issue is that it is responsible for the high efficiency of the heart, thanks to which the body has greater endurance to physical or mental effort.
