Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that plays a crucial role in maintaining overall health. It is naturally produced in the skin upon exposure to sunlight and can also be obtained from certain foods and supplements.

One of the key roles of vitamin D3 is its involvement in the regulation of calcium and phosphorus absorption in the intestines. As such, Vitamin D3 is often recognized for its association with bone metabolism, as it is involved in bone formation and remodeling. It is also involved in the modulation of immune cell activity, helping the body defend itself against external agents. This immune-modulating function underscores the importance of maintaining adequate levels of vitamin D3 for overall health and well-being.*

Vitamin D promotes the synthesis of proteins that rely on vitamin K for their activation. Indeed, vitamin K serves as a crucial coenzyme, facilitating the carboxylation process, particularly in the case of Gla proteins. This transformation involves converting glutamic acid (Glu) within specific proteins into γ-carboxyglutamic acid (Gla). Carboxylation stands as an indispensable step for the majority of these proteins to function effectively. These carboxylated vitamin K-dependent Gla proteins share a common feature of binding calcium. Thus, the collaboration between vitamin K and vitamin D helps a precise allocation of calcium to targeted sites within the body.*

Vitamin K1 is predominantly absorbed by the liver and is instrumental in activating clotting factors. In contrast, vitamin K2 serves a broader role, extending beyond the liver to activate various vitamin K-dependent proteins such as osteocalcin and MGP. Vitamin K2, also known as ‘menaquinone,’ exists in multiple forms, with MK-4, MK-7, MK-8, and MK-9 being among the most recognized. Current scientific understanding suggests that menaquinone-7 (MK-7) is the most efficacious form of vitamin K2. MK-7 demonstrates exceptional absorption and possesses a prolonged half-life, allowing it to remain coenzymatically active within the body for an extended duration. This is the reason why, our formula contains K2 of MK-7 while we did not included other vitamin K forms such as K1.*
