The ideal way to supply your body with sufficient vitamin D is direct sunlight, of which only 15 minutes are needed daily in summer. The skin on your body can synthesize the individually required amount of vitamin D3 itself, which is why vitamin D is also called the "sun vitamin". It acts as a prohormone in your body and influences the metabolism of many individual cells by controlling vital metabolic processes.

However, long office hours, the northern latitude in Europe, and the natural short daylight hours in winter make it difficult to produce enough vitamin D. About 90 % of the required vitamin D must be synthesised by the skin and only about 10 % can be absorbed through daily food. Even a varied and healthy diet often does not protect you from a vitamin D deficit, because foods contain only very small amounts of vitamin D.

The smart combination of the following ingredients

VITAMIN D3⁺OIL contains the micronutrient duo of vitamins D3 and K2 as well as valuable MCT oil for optimal vitamin effectiveness.

Vitamin D3 − the sun vitamin

Vitamin D3 (cholecalciferol) is a prohormone and thus the most important form of vitamin D. It is produced by the body in the skin under the influence of sun rays, more precisely UVB rays. Depending on requirements, a certain quantity is synthesised and passed on to the corresponding cells. Of the total amount of vitamin D3 required, 90 % can be synthesised by the skin and only 10 % can be absorbed through food. This can lead to a vitamin D deficit, especially in winter when there is less sunlight. As a prohormone, the sun vitamin supports the normal function of the immune system and thus ensures you have a strong immune system even in the winter months. It also helps maintain normal bones and teeth in the body and normal muscle function.

Nutritional table

Ingredients per drop (in mg) %RM
MCT oil, coconut based 26,5 mg **
vitamin K2 (MK-7 all-trans) 7,5 mg (11 μg pure vitamin K2)   15 %
vitamin D3 (cholecalciferol)     0,025 mg 500 %


Just 1 drop a day is enough for your optimal vitamin D supply in summer due to the maximum concentration.

In winter, experts recommend 2-6 drops a day due to the low level of sunlight.
Since the drops are tasteless it is uncomplicated for you to reach your individual daily dose.


Our tip:

Take your daily dose pure in the morning, or jazz up your breakfast.
For example, you can make your green smoothie, fruit muesli or yogurt even healthier.
If you're a fan of ketogenic nutrition, then put your daily dose in your Rocket Coffee and it will give you the extra power of vitamin D and K. It doesn't matter whether you take your personal dose in the morning or in the evening. You'll be flexible and well cared for around the clock.


For an optimal performance foundation, best combine VITAMIN D3⁺ OIL with KRILL BOOST. In addition to vitamin D, your body also needs a sufficient supply of omega 3 fatty acids as a basis for mental performance and a healthy well-being.

Liquid sun for bright days

I absolutely love Braineffect Vitamin D oil! I heard that one should use a liquid for enhanced bioavailability. Also I don’t like swallowing capsules and usually mix the oil in my morning bowls. Never thought this would happen, but I do feel happier and healthier now!
absolutely recommended!

Why are vitamins D and K combined?

Our VITAMIN D3⁺ OIL combines the power vitamins D and K, which are dissolved in MCT oil and then can be absobed directly by the body. They also complement each other and support the immune system as well as your bones. Together with vitamin D, vitamin K2 forms the perfect team, promoting the absorption of calcium in the bones, teeth and muscles. If there is an imbalance of both vitamins, calcium forms deposits in the walls of your blood vessels and this can damage your organs. It is therefore particularly important to take both vitamins at the same time to achieve a healthy balance.

Is there a danger of vitamin overdose?

The VITAMIN D3⁺ OIL contains 25 micrograms of vitamin D3 per drop, corresponding to 1,000 IUs. If you take a sunbath plus one drop per day in the summer and increase your personal daily dose in winter to 5 drops, you will not need to worry about a vitamin overdose. Excessive vitamin D supplementation only begins to have adverse effects at a dose of 40,000 IUs daily over a long period of time.

Do I have to take VITAMIN D3⁺ OIL regularly?

Use of the vitamin complex is very simple. In summer, you only need a few drops, and in the winter, you increase the number of drops to support your store of vitamin D.

Where do the natural ingredients of VITAMIN D3⁺ OIL come from?

VITAMIN D3⁺ OIL is suitable for vegetarians, as it is made from natural ingredients. The vitamin D3 comes from lanolin, wool grease from sheep, which is produced when the wool is washed. No animals are harmed when the wool is recovered and the wool is then processed to make other products. The pure vegetable vitamin K2 is made from the oil of the soya bean. Both vitamins are dissolved in pure MCT oil, which is obtained from coconut oil.
