Approximately 50% of the Spanish population is deficient in vitamin D. Our supplement contains 2,000 IU of vitamin D3 combined with vitamin K2, specifically menaquinone-7, which is the most bioavailable, longest-lived and scientifically supported form of vitamin K2. This combination not only promotes intestinal absorption of calcium, but also its proper deposition in the bones. A key differentiating factor is its association with naringin, an active compound that helps bone formation and also reduces bone resorption (or breakdown). All of this is combined with magnesium and zinc to maximize bone and immune benefits. In addition, our ready-to-use formula in vial form offers convenience, and compared to other brands, its vial format improves absorption compared to solid pharmaceutical forms. Composition Vitamin D. Vitamin D, specifically D3 or cholecalciferol, is a fat-soluble vitamin essential for the proper functioning of our bodies. It is produced by our skin through sun exposure and is also obtained through diet, such as from fatty fish and eggs. In addition, it influences the immune response and mood. Vitamin K. Vitamin K, especially K2 or menaquinone, plays a key role in bone and cardiovascular health by directing calcium deposition in bones, preventing its accumulation in arteries and soft tissues. It is found in fermented foods such as cheese and yogurt. Naringin is a flavonoid found in citrus fruits, especially grapefruit peel, with antioxidant and anti-inflammatory properties. Naringin helps prevent bone loss by reducing the formation of osteoclasts, or cells that destroy bone. Magnesium: This mineral is essential for regulating neural, hormonal, and muscle functions. It plays a role in energy metabolism, psychological function, maintaining bones and teeth, and regulating muscle contraction. It helps reduce fatigue and exhaustion. Magnesium citrate is better absorbed and increases concentrations in the brain and muscles, achieving the desired effects. Zinc is an essential element that contributes to the normal functioning of the immune system by stimulating the formation of white blood cells. It also plays a role in the metabolism of carbohydrates and fatty acids, as well as in the synthesis of DNA and proteins. The production of keratin depends on its presence, which is why it is involved in hair growth.
