What is Vitamin K2 + D3?
Vitamin K2 + D3 is a dietary supplement in liquid form that contains two important vitamins in a balanced concentration.
- Natural Vitamin K2 (extracted from chickpea fermentation), in the form of menaquinone-7. Patented and clinically validated (MenaQ7®). High absorption and longer persistence in the bloodstream.
- Vitamin D in its most bioactive form, cholecalciferol (D3).
Few nutrients work better together than vitamin K2 and vitamin D3.
But balance between nutrients is essential.
It is important that the concentration of vitamin K2 is balanced with vitamin D3 to achieve the desired benefits and avoid overdosing. Although no fixed ratio between the two has been established, results from scientific studies indicate that for typical vitamin D3 supplementation (1,000 IU/day), an intake of 90 µg of vitamin K2 per day is appropriate (1,2).
How does menaquinone-7 (MK-7) + vitamin D3 work?
Vitamin K2 helps direct calcium into the bones (keeping it away from the arteries), while vitamin D3 promotes the absorption and utilization of calcium from food. Proper calcium use requires that it be deposited mainly in bone structures and kept away from the arteries. This process depends on the synthesis of vitamin K–dependent proteins, osteocalcin and matrix GLA protein. This reaction is essential for optimal and healthy calcium utilization.
Nourish and strengthen your bones
Bone is a living tissue that is constantly changing. Old or worn-out bone is broken down by cells called osteoclasts and replaced by bone-building cells known as osteoblasts, in a renewal process called bone remodeling. Vitamin K2 helps stimulate the activity of osteoblasts and inhibits that of osteoclasts. At the same time, it participates in the activation of the protein osteocalcin, a chemical reaction necessary for optimal and healthy calcium utilization.
Cardiovascular health
Vitamin K activates matrix Gla proteins (MGP), which are responsible for protecting the arteries from calcium deposits.
What´s so special about Vitamin K2 (MenaQ7®)?
Patented vitamin K2 clinically validated as MK-7. MenaQ7® is produced under GMP standards, with garbanzos that are not genetically modified. It is free of gluten, dairy products and soy.
All K vitamins have a similar structure, but they differ in the length of the “side chain”: the longer the side chain, the better the effect and effectiveness. Consequently, long-chain menaquinones (especially MK-7) are the most desirable, since they are almost completely absorbed (the body requires smaller doses) and remain in the blood for a longer time. This makes vitamin K2 also available to tissues, i.e. bones, arteries and soft tissues.
MK-7 is more effective because of its greater:
- Absorption and lifespan.
- Maintaining blood levels.
What is special about vitamin D3?
Vitamin D3 (cholecalciferol) is derived from lanolin and is bioidentical to the form produced by the skin. Vitamin D is associated with various physiological systems.
It contributes to the normal functioning of the immune system and muscles, supports the process of cell division, and helps maintain bones and teeth under normal conditions.
