7Nutrition Omega-3 D3 + K2 is a dietary supplement combining omega-3 fatty acids (EPA and DHA) with vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone). These ingredients are often analyzed together in scientific literature due to their role in cardiovascular system function, calcium metabolism, and physiological processes related to bones and the immune system.
Omega-3 fatty acids (EPA and DHA)
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are polyunsaturated fatty acids from the omega-3 family. They are important components of cell membranes and participate in many metabolic processes in the body.
Biological functions of omega-3
- Component of cell membranes
EPA and DHA are incorporated into phospholipids of cell membranes, influencing their fluidity and the functioning of cellular receptors.
- Influence on inflammatory and metabolic processes
Research indicates that omega-3 fatty acids may affect inflammatory mediators and metabolic processes through their metabolites and cellular-level activity.
- Support for the cardiovascular system
A meta-analysis of randomized clinical trials has shown that omega-3 supplementation may support proper functioning of the cardiovascular system.
Vitamin D3 (cholecalciferol)
Vitamin D3 is a fat-soluble vitamin that plays a key role in regulating calcium and phosphorus metabolism in the body.
Vitamin D3 helps in:
- maintaining normal calcium levels in the blood,
- maintaining healthy bones,
- proper muscle function,
- proper functioning of the immune system,
- maintaining healthy teeth.
Vitamin K2
Vitamin K2 in the form of menaquinone-7 (MK-7) is one of the most bioavailable and biologically active forms of this vitamin. Its key role is to activate proteins responsible for proper calcium utilization in the body, especially osteocalcin. This protein is involved in directing calcium to bone tissue, where it is needed to maintain proper bone structure, rather than accumulating in blood vessel walls. As a result, vitamin K2 MK-7 supports both proper bone mineralization and cardiovascular system function by helping to limit arterial calcification.
