The motto of father and son is: "Primum nihil nocere, bene facere secundum", which means: Firstly do no harm, secondly do good. The recommended dosage of food supplements must not be exceeded.

This means that the fat-soluble vitamin can be absorbed very well by the body - even independently of meals. As long-chain menaquinone-7, vitamin K2 is particularly bioavailable and is optimally absorbed by the body. It is also much more stable than vitamin K1 and is present in the body for up to 3 days. Nutritional values: One drop contains 15 µg vitamin D3 (=600 I.U.) and 15 µg vitamin K. Ingredients: Sunflower oil (98%), antioxidant extracts containing strong tocopherols (vitamin E of natural origin), vitamin K2-MK7 (all-trans-menaquinone).
