Highly dosed fat-soluble vitamin duo
Vitamin D3 is involved in metabolic processes such as bone metabolism, muscle function, cell division, tooth maintenance and the immune system in the body. It has been found that vitamin D receptors are present in almost all organs and tissues, which suggests that it has a far-reaching influence. It is particularly well known as an important nutrient for bones and for its contribution to a functioning immune system.
Vitamin K2 (menaquinone) occurs in "side chains" of different lengths, which determine how well it is absorbed by the body. Menaquinone-7, abbreviated to MK-7, is by far the most effective variant of vitamin K2. It contributes to normal blood clotting, but also plays an important role in maintaining healthy bones, just like vitamin D3. The synergistic effect of both vitamins cannot be denied in this context.
With the further development of BIOGENA Vitamin D3 & K2 Drops, we have taken our existing formula to a new level and are launching the high-dose combination of the two fat-soluble vitamins in liquid form. A special feature of BIOGENA Vitamin D3 & K2 Drops is the combination of high-dose vitamin D3 and vitamin K2 in a 2:1 ratio. Each drop contains 5000 I.U. of vitamin D3 and 62.5 µg of vitamin K2. As a practical innovation, the drops come with a dropper - so the desired amount can be dosed exactly on a teaspoon. They are dissolved in high-quality MTC carrier oil made from coconut, which is a good matrix for fat-soluble vitamins.

At Biogena, “pure substance principle” means that we do not use technological additives which are used for the fully automated manufacturing of tablets, capsules and pills (e.g. anticaking or release agents and so forth) or additives that are used for optical reasons or for enhancing the taste of the products (artificial aroma, colouring agents, coatings etc.). Due to a semi-automatic manufacturing process, we can avoid these substances that often have a higher proportion in customary products than the actual active ingredients. In the case of nutritional supplements, additives have to be indicated in the list of ingredients, in the case of medication you find these substances under “inactive ingredients”. Here, the patient or customer can get useful information. Concerning the single ingredients, we also care for our raw materials to be free of carrier substances. In cases where this is not possible, we use natural food components such as maltodextrin, cellulose powder or calcium carbonate. The majority of our ingredients is produced exclusively for us – free of carrier substances (e.g. our enzymes our probiotics: other manufacturers often use lactose as a carrier – the product batches produced for us are explicitly without carriers).

Biogena cooperates with respected physicians and therapists in many different countries. With them, you are in good hands. You can also buy our products from our Biogena stores in Vienna, Linz, Salzburg, Graz, Natternbach, Freilassing and Frankfurt (Germany) as well as online at
