Vitamin D3 + K2 Oil

Vitamin D and vitamin K are a vitamin duo that work together in calcium metabolism to help maintain normal bones. Vitamin D also contributes to normal muscle function and supports the normal functioning of the immune system. One drop of our supplement contains 1,000 international units of vitamin D3 and 20µg of vitamin K2. The vitamin duo is particularly suitable for people who do not eat enough green leafy vegetables or herbs and therefore do not get enough vitamin K from their diet.

Vitamin D and K: embedded in MCT oil

Vitamin D3 and K2 are fat-soluble and are better metabolised when taken with oil. That is why we embed the active ingredients in our organic coconut MCT oil. It is tasteless and odourless and has a good shelf life.

Vitamin D in food

Unlike many other vitamins and nutrients, the need for vitamin D cannot be fully met by food. If we get enough sun, we produce about 80 per cent of the vitamin D we need through our largest organ, the skin. We can only get 20 per cent from our diet, assuming we eat foods that contain vitamin D.

There are relatively few foods that naturally contain vitamin D. Adequate amounts of vitamin D can be found in cold-water fish such as mackerel, salmon, sardines and blue fish. Vitamin D is found in high concentrations in the liver of these fish. Certain mushrooms, such as shiitake mushrooms, can also contain vitamin D. However, the main source of this important vitamin is still sunlight or appropriate supplements.

Self-synthesis of vitamin D from the sun

During the summer months, the body can produce some of the vitamin D3 it needs from the sun's UV-B rays. How much vitamin D3 your body produces depends not only on the season and time of day, but also on how much time you spend outdoors, the clothing you wear, your skin type, your age and whether you use sunscreen.

People living near the equator have optimal vitamin D levels with sufficient sun exposure without sunscreen. The further north we live, the weaker the sun and the weaker the natural synthesis of vitamin D. As a result, northern Europeans cannot get enough vitamin D between October and April without supplementation, unless we eat large amounts of cold-water fish. Eskimos, for example, balance their vitamin D levels by eating fish liver. In the summer months, you can make enough vitamin D by spending about 20 minutes outdoors at lunchtime, ideally wearing as little clothing as possible and without sunscreen. As we get older, our own synthesis declines.

Because individual levels can vary so much, we recommend that you have your vitamin D levels checked by your doctor.

Vitamin K2: For the bones

Vitamin K plays a key role in bone metabolism and blood clotting. In addition to foods rich in vitamin K, vitamin K supplements can also help to ensure a good supply. The main sources of vitamin K are green vegetables such as spinach and some types of lettuce and cabbage such as kale and Brussels sprouts, milk and dairy products, meat and eggs.

Supplementing with vitamin K may also be useful with a higher dose of vitamin D. This is because vitamin D, in combination with vitamin K2, controls the cells responsible for building and breaking down bones. The vitamins also contribute to calcium metabolism.

Two vitamins, many effects

The European Food Safety Authority (EFSA) has already approved the following health claims under the Health Claims Regulation:

• Vitamin D helps maintain normal blood calcium levels.
• Vitamin D and K help maintain normal bones.
• Vitamin D helps maintain normal muscle function.
• Vitamin D helps maintain normal teeth.
• Vitamin D helps maintain normal immune system function.
• Vitamin D has a role in cell division.
• Vitamin K helps maintain normal blood clotting.

Vitamin D and K intake recommendations

The German Nutrition Society (DGE) recommends a daily intake of 20 micrograms (µg) of vitamin D for children, adolescents and adults. 1 µg is equal to 40 international units (IU), so 1 IU is equal to 0.025 µg.

The DGE also recommends a daily intake of 70 to 80 μg of vitamin K for adult men and 60 to 65 μg for adult women. These recommendations are based on healthy adults.

We recommend that you have your individual vitamin D and K requirements assessed before taking a supplement. One drop of our food supplement contains 1,000 international units of vitamin D3 and 20 μg of vitamin K2, which provides 100 per cent and about 25 per cent of the daily requirements of vitamin D and vitamin K respectively.

People taking anticoagulant medication should seek medical advice before taking vitamin K supplements. Food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose. Keep out of the reach of young children.

General usage: Take 1 drop undiluted daily.

People taking anticoagulant medication should seek medical advice before taking vitamin K supplements. If you are unsure of your individual requirements, we recommend that you have an analysis carried out, for example by your GP.
