Vitamin K2 occurs in a variety of molecular structures known as homologues which are named according to the length of the molecule's side chains (e.g., MK-4 or MK-7). The MK-7 form of vitamin K2 is currently considered the most effective: it remains active in the body for a particularly long time and is able to cover the functional K2 requirement of the body in relatively small doses.
The vitamin K2 MK-7 molecule itself also occurs in different geometries, of which only the trans isomer is biologically active. Vitamin K2 is designated "all-trans" when it consists of at least 98% trans isomers. K2VITAL®, a registered trademark of Kappa Bioscience AS from Norway, goes even further: this high-quality active ingredient consists of 100% vitamin K2 MK-7 trans isomers.
In order to achieve an even distribution of vitamin K2, and thus ensure precisely dosed capsules, the addition of a carrier is necessary: our formulation includes 100% non-nano microcrystalline cellulose as a carrier to prevent the usual active ingredient fluctuation between capsules.
The only other ingredient is premium gum arabic, cultivated without the use of plant protection products. In contrast to microcrystalline cellulose, a widely used synthetic filler often mixed with nanoparticles, gum arabic is a natural, fibre-rich food. Our fair trade gum arabic is climate neutral and is sustainably cultivated to conserve resources.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
