Vitamin D3/K2 Oil 1000IE/20µg Drops 50 ml

The importance of vitamin D3 and vitamin K2 for the body has been researched for many years. Nowadays it is known that these two vitamins should even be taken together in the best case, as they complement each other optimally. 

Vitamin D

Vitamin D, which has been researched for decades, is known for its versatile and amazing effects on almost all areas of the human body. Vitamin D (calciferol) is also known as the "sunshine vitamin" because it can be largely produced by the body itself with the help of sunlight.

There are two different forms of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D2 is the form that occurs mainly in plants, while vitamin D3 occurs mainly in non-plant organisms. Thus, the vitamin D3 form is also present in humans and is more absorbable by the body.

Studies based on vitamin D produced from lanolin (wool wax) have shown:

• Vitamin D contributes to normal immune system function
• Vitamin D contributes to the maintenance of normal teeth and bones
• Vitamin D contributes to the maintenance of normal muscle function
• Vitamin D contributes to normal absorption and utilization of calcium, phosphorus and normal calcium levels in blood

A deficiency of vitamin D can therefore have very far-reaching and serious consequences. 

Symptoms of vitamin D deficiency

• Persistent fatigue
• Low mood
• Sleep disturbances
• Concentration problems
• Osteoporosis (bone loss)
• Osteomalacia (softening of bones)
• Susceptibility to infections
• Respiratory diseases
• Diabetes
• Multiple sclerosis
• Dementia
• Mood swings
• Lack of interest
• Heart rhythm disorders

>> A vitamin D deficiency can be quickly detected by a blood count. Almost one in three Germans has only a deficient supply of vitamin D. Especially in winter, a deficiency becomes all the more likely.

 Causes of vitamin D deficiency

• Lack of sunlight (e.g. due to work)
• Stress
• Lack of leisure time
• Advanced age
• Smoking
• Dietary vitamin D deficiency (especially vegetarians and vegans, as it is found mainly in animal foods and fatty fish)
• Absorption disorders (e.g. inflammations or diseases of the gastrointestinal tract)
• Diseases with low fat absorption (e.g. exocrine pancreatic insufficiency)  

Prevention of vitamin D deficiency

Vitamin D deficiency can often be compensated or prevented by regular but moderate sunbathing anyway outdoor activities. However, for many people this form of vitamin D intake is not possible (e.g. due to work, illness). The oral intake (in drop form) of vitamin D is therefore a quick and effective way to prevent or quickly compensate for a vitamin D deficiency.

Our liquid vitamin D3 oil can be easily and individually dosed due to the amber glass bottle with pipette lid. D3 is a fat-soluble vitamin, so it should always be taken with fat and is with us for optimal absorption already dissolved in corn oil.  

Vegan vitamin D3 from lichen? No thanks!

Many suppliers advertise plant-based vitamin D3 from lichens. Lichens belong to the fungi or algae and therefore also contain vitamin D3.

Here are the reasons why we do not offer our vitamin D3 from lichens:

• The raw material for vitamin D3 from lichens costs about 3x as much as that from lanolin (wool wax). For many users this high price is not affordable. If you do find a product made from lichen that is comparable in price, you should question exactly how this can be possible.
• Almost all studies on vitamin D3 and its effectiveness are based on vitamin D3 extracted from lanolin (wool wax). Whether vitamin D3 from lichens with a different chemical structure has the same effect has yet to be adequately proven.
• Vitamin D3 from lichens is not sustainable because lichens take years to decades to grow. Where do the lichens for the thousands of lichen products on the market come from? Good question! After all, there are not as many lichens in the world as there are supplies.
• Vitamin D3 derived from lichens is also usually unsustainable, as these lichens are often taken from the natural ecosystem, even though many animals (such as reindeer) rely on this food source.
• Vitamin D3 extracted from lichens requires an enormous amount of resources and a high input of energy. This is also not environmentally friendly.  

Vitamin K

Vitamin K is a fat-soluble vitamin that is very important for our blood clotting and maintaining normal bones.

There are two natural forms of vitamin K: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).

Vitamin K1 is the form that occurs naturally in plant foods.

Vitamin K2 the form that is produced by bacteria (e.g., intestinal bacteria).

Vitamin K2 is the active form of vitamin K produced by the conversion of vitamin K1 to K2 in the organism. In humans, this conversion occurs in the intestine and therefore a healthy intestine is a prerequisite for effective absorption of K2.

Plant foods such as green leafy vegetables, cabbage or avocado contain the vitamin K1 form. There are only a few plant foods that already contain the active vitamin K2 form. Raw sauerkraut, for example, is an exception. Vitamin K2 is otherwise found almost exclusively in animal foods, such as butter, egg yolks, liver, some cheeses, and the fermented soy product "natto".

Some symptoms that may indicate a vitamin K deficiency:

• Susceptibility to bruising
• Frequent bleeding from nose, gums or wounds, often also in the stomach or intestines
• Dwindling bone density/brittle bones
• Poor cardiovascular health
• A vitamin K deficiency can be quickly detected by blood work  

Advantages of taking K2 are:

• Important support for the body's own blood clotting (this protects against excessive blood loss in the case of injuries, for example)
• Maintenance of normal bones, as it helps to incorporate calcium into the bones  

Important differences in the quality of vitamin K2

Not all vitamin K2 is the same, as there is synthetically produced vitamin K2 and vitamin K2 obtained via fermentation of natural source materials (e.g. soybeans in our case). Synthetic vitamin K2 is present in the cis-form; this is not endogenous and therefore cannot be utilized by the body.

The natural source form of vitamin K2 (obtained by fermentation of soybeans using Bacillus subtilis cultures) is in the menaquinone 7 all-trans form. This form is considered to be of the highest quality, as it guarantees optimal absorption in the body.

A fast and uncomplicated alternative to the intake of vitamin K2 is the oral intake of vitamin K2 oil. Our vitamin K2 is already dissolved in oil, since vitamin K2 as a fat-soluble vitamin can only be absorbed by the body in combination with oil.

Our vitamin K2 oil already contains the active form of vitamin K, namely vitamin K2 in the menaquinone/all-trans form. This means that the contained vitamin K2 is directly available to the body and does not have to be converted into the active form of vitamin K first.
