Advantages at a glance Contains a years supply of 1700 drops, each containing 1000 IU of vitamin D3. Optimal ratio of vitamin D3 to vitamin K2 High-quality brand product from K2VITAL® Highly bioavailable MK-7 all-trans vitamin K2 from natto With high-quality MCT oil from coconut Supports immune system, bone and muscle function Made in Germany 100% vegetarian natural product Our vegetarian Vitamin D3 + K2 drops combine both vitamins in the optimal ratio: 1000 IU of Vitamin D contains 20 µg of Vitamin K2. Valeo Vita Vitamin D is obtained naturally from lanolin (wool wax) and is therefore not only gentle in its production, but also has optimal bioavailability. Our Vitamin K2 MK-7 consists of 99.5% all-trans isomers, which is essential for optimal bioavailability. All-trans MK-7 boasts the longest half-life and highest efficacy. It is produced using plant-based natto. The drops offer the advantage of individual and simple dosing. Depending on the season, age, or weight, the intake can be easily adjusted to meet individual needs. Vitamin K2 also plays an important role in bone metabolism. It is crucial for the activation of osteocalcin and matrix Gla protein, which are needed to transport calcium into the bones. Vitamin D, in turn, promotes the formation of osteocalcin and matrix Gla protein, thus supporting bone metabolism and bone formation. One vitamin therefore forms important, bone-maintaining proteins, while the other activates these proteins and makes them effective. It therefore makes perfect sense to take both vitamins simultaneously, as they complement each other. Quality characteristics of vitamin K2 With K2VITAL®, we use the highest quality vitamin K2 product currently available on the market. Vitamin K2 refers to a group of several forms classified as MK-4 to MK-14. Here, the M stands for menaquinone, and the numbers 4-14 indicate the length of the side chain. This side chain length, which is composed of isoprenyl units, indicates the bioavailability of the vitamin K2. An important quality characteristic is the geometric structure of the molecule: the hydrogen atoms of the side chains can either all be arranged on one side (cis form) or opposite each other (trans form). All-trans MK-7 has the highest bioavailability and the longest half-life. This form circulates in the bloodstream for the longest time and therefore exhibits the highest efficacy. The high-quality all-trans MK-7 should not be confused with the cheaper, biologically inactive all-cis MK-7.
