Vitamin ADEK in drops, 20 ml = 600 drops

1 drop include:

  • 240 mcg / 800 IU (30% *) vitamin A,
  • 20 μg / 800 IU (400% *) vitamin D3,
  • 4 mg (33% *) of vitamin E (a mixture of tocopherols),
  • 20 μg (27% *) of vitamin K2 (MK-7).
  • *% of the recommended daily intake

Vegan product


Vitamin ADEK Dr. Jacob's is:

  • Complex of all four fat-soluble vitamins;
  • Broad-spectrum of action (see below);
  • Top-quality natural vitamins;
  • Vitamins already dissolved in natural MCT oil from coconut;
  • With a slight citrus aftertaste thanks to bergamot oil;
  • Optimal bioavailability: they are already absorbed in the mouth!

Drops Vitamin ADEK Dr Jacob's is the first such product on the market. Due to the fact that the vitamins are dissolved in the oil, they are absorbed directly into the bloodstream in the mouth (bypassing the digestive system).


Vitamins A, D3, E and K2 have scientifically proven beneficial effects on the proper functioning of the body:

Vitamin A for:

  • correct vision,
  • the functioning of the immune system,
  • maintaining healthy skin,
  • the proper condition of the mucous membranes,
  • iron metabolism.

Vitamin D3 for:

  • the immune system,
  • calcium absorption,
  • healthy bones and teeth,
  • muscle function.


Vitamin E for:

  • protecting cells against oxidative stress and slowing down the ageing processes (vitamin E is one of the strongest natural antioxidants).

Vitamin K2 for:

  • proper blood clotting,
  • healthy bones and teeth.


Sources of vitamins:

Vitamin A is obtained in one of the best European laboratories in the synthesis process (synthesis, i.e. the process of combining).

Vitamin D3 is obtained from sheep wool lanolin (extracted using UV irradiation).

Vitamin E (a mixture of natural tocopherols) is obtained from vegetables.

Vitamin K2 is special because we obtain it from essential oils. This ensures the highest amount of pure menaquinone-7 (MK-7), its great bioavailability and bioactivity, and no GMO contamination (more at the end of the description)


MCT oil

In Dr Jacob's products with vitamins A, D, E and K in liquid, we use the MCT fatty acid fraction obtained from coconut oil. Unlike coconut oil itself, which is rich in saturated fatty acids, which are not beneficial to your health as a food product, MCT medium-chain fatty acids have many beneficial health and dietary properties, many of which are scientifically validated. One of them is that MCT does not adversely affect the blood lipid profile and does not increase the risk of cardiovascular disease.

The use of MCT has a very beneficial effect on the stability of vitamins dissolved in this oil. Compared to other oils, MCT also has a much greater resistance to rancidity. Thanks to this, the vitamins of Dr Jacob's can have a maximum use-by date (2 years) and stay fresh long after the bottle is first opened. MCT oil is tasteless, which is important when giving vitamins to young children.


MCT oil (coconut, 48%), a mixture of tocopherols (natural vitamin E), cholecalciferol (vitamin D3), retinol palmitate, vitamin K2 (all-trans menaquinone-7), aroma - bergamot oil.

Portion recommended for consumption during the day and directions for use:
1-2 drops on a teaspoon or directly into the mouth.

Drop into the mouth and spread over it with the tongue.

Additional information:

  • adults, especially obese people (BMI 30+ kg / m2): 2 drops;
  • adults, in particular: pregnant and lactating women, people working at night, people with dark skin, obese adults and obese children (BMI over 90 percentile for the local population): 2 drops;
  • children up to 18 months of age and premature babies (after consulting a doctor): 1 drop.

Note: The product should not be consumed by people taking anticoagulants containing vitamin K antagonists (e.g. warfarin and acenocoumarol). Such persons should consult a physician when taking the product!

The high content of bioactive vitamin E may, in some people with irritation of the mucosa, cause a slight feeling of "scratching" in the throat.

Ways of obtaining MK7:

from the fermentation of soybeans or essential oils

There are two ways to obtain vitamin K2 - by fermenting soybeans or from vegetable essential oils.

Soybean fermentation
In the production of vitamin K2 MK-7 in the fermentation process, bacterial preparations and special solvents are added to the soybean. As a result of using this method, many side substances are always formed, including other menaquinones, e.g. MK-4, -8, -9. Many of them are redundant or cis-shaped (not bioavailable). The amount of such impurities depends on the quality of the fermentation.

Since soy is used in the production, allergens of soy may also be present in the final extract. Unfortunately, there is often no information as to whether the soybeans used are genetically modified. Vitamin K2 obtained in this way is described by the producers: "from natto", "from soybean fermentation", etc.

Extracting vegetable essential oils
The method of extracting pure K2 MK-7 from essential oils was invented in 2006 by Norwegian researcher Dr Inger Reidun Aukrust and his team. They found a way to produce the pure form of all-trans MK-7 (menaquinone-7, MenaQ-7) vitamin K2 from natural plant essential oils: geraniol * and farnesol **, in a strictly controlled organic synthesis process (synthesis means fusion process, do not confuse with synthetic - artificial).

There are two types of forms of vitamin K2 molecules - cis and trans. The cis forms are biologically inactive while the transforms are at their full biological potential. Most of the vitamin K2 products on the market are fermented and contain K2 in both cis and transforms.

The advantage of the method of extracting K2 from essential oils is that only vitamin K2 is obtained in the pure, best and fully bioavailable *** form of MK-7. And this is the form in Dr Jacob's.

As soy is not used in this process, possible GMO contamination is also avoided and a product safe for allergy sufferers is obtained.

* Geraniol - an organic chemical compound from the group of unsaturated terpene alcohols. It is found in essential oils. It has an intense fragrance associated with freshness and geraniums, which is why it is often used in many fragrance compositions used in perfumes. It is obtained from rose, pelargonium and lemon oils.

** Farnesol - an organic chemical compound, alcohol from the terpenes group, mainly used as a fragrance with the scent of lily of the valley. It is a component of many essential oils, including lily of the valley, linden, nutmeg and acacia. It is obtained from the oils of the linden flower. It is used in the perfumery and cosmetics industry

*** Bioavailability (bioavailability) - determines the degree of absorption of a substance that enters the circulation and is actually used by the body.
