Vitamins A, D, and K2 are fat-soluble vitamins that play essential roles in various physiological processes, and they are interrelated in several ways. While they have distinct roles in the body, these vitamins depend on each other to some extent.

One example of their interdependence is their relationship with bone health. Vitamin D helps to regulate calcium and phosphorus levels in the body, which are necessary for bone mineralization. Vitamin K2 activates proteins that help to transport calcium into bones, while vitamin A helps to regulate bone cell activity. Together, these vitamins work synergistically to support bone health. Another example is their role in immune function. Vitamin A is essential for the development and maintenance of immune cells, while vitamin D helps to regulate the immune response. Vitamin K2 also supports immune function by activating proteins that help to fight infection.

Vitamin A plays a crucial role in the synthesis and metabolism of cholesterol, which is necessary for producing hormones, cell membranes, and bile acids. Vitamin A also has antioxidant properties, which can help to protect the heart from oxidative damage. Oxidative stress can lead to inflammation and damage to the blood vessels, which can contribute to the development of cardiovascular disease. Moreover, vitamin A has been shown to have a regulatory effect on cardiac cell activity. Vitamin A can regulate the proliferation and differentiation of cardiac cells, essential for maintaining heart function. One review article published in the Journal of Clinical Medicine in 2020 highlighted the role of vitamin A in regulating lipid metabolism and promoting arterial integrity.

Vitamin D has been shown to have cardioprotective effects by supporting endothelial function. Vitamin K2 has also been shown to have cardioprotective effects; a study showed that combined supplementation with vitamin K2 and D improved arterial health in postmenopausal women.
