Science-Backed
Experts recommend maintaining a vitamin D level of 60-80 ng/ml in the blood in order to fully benefit from the many advantages that vitamin D offers for health. But especially in the months when there is not a lot of sun exposure, it is almost impossible to generate enough vitamin D3.
A winter walk is unfortunately not enough, studies have proven this. North of the 42nd parallel (above Rome), the sun is simply too low in the winter months to allow enough UVB rays to pass through that would be necessary to produce vitamin D.
During the summer months, a person with fair skin under direct sunlight (in swimwear, without sun protection) produces around 10,000 IU in 10 to 20 minutes at noon (depending on the skin type). Depending on the pigmentation, people with dark skin produce less.
Three sunbaths a week are enough to be optimally supplied with vitamin D. The vitamin D stored over the summer lasts about 2 months. After that, the body relies on food or supplements.
Most people use a sunscreen with a high protection factor in the summer. But sun protection factor 8 already blocks the formation of vitamin D in the skin by up to 95%.
No wonder a large part of the population in Europe suffers from chronic vitamin D deficiency, not only in the winter but also in the summer.
Inadequate intake through food
Vitamin D is mainly found in oily fish, cod liver oil, offal and in small amounts in milk, eggs, and butter. However, the consumption of milk, eggs or butter, which is most commonly eaten in our latitudes, is too low to be able to absorb sufficient amounts of vitamin D through food.
The key to our health
According to a study by the University of Oxford, gene receptors all over the body need sufficient amounts of vitamin D for gene expression (conversion of the genetic information) to function normally.
A lack of vitamin D can, therefore, lead to serious illnesses. The reason why vitamin D is the key to our health is in our genes.
What can vitamin D do for your health?
The effects of a vitamin D deficiency can clearly be seen from what vitamin D is responsible for in our body:
supports the normal function of an intact immune systemhelps build and maintain normal strong bonessupports a normal calcium level in the bloodcontributes to the maintenance of normal teethsupports normal muscle functionhas a function in cell divisionplays an important role in the absorption and utilization of calcium and phosphorus
Vitamin D3 drops are ideal for replenishing vitamin D storage and for maintaining a healthy vitamin D level all year round.
Vitamin D and Vitamin K2 should always be taken together
Anyone who regularly takes high doses of Vitamin D3 as a nutritional supplement has an increased need for Vitamin K2. Because as a result of the intake of Vitamin D, increased amounts of calcium will be taken out of the food by the intestine. At the same time, the body increasingly produces Gla proteins, which have the task of transporting calcium in the body.
Gla proteins can only be activated through vitamin K2. When activated, calcium is bound to the proteins and transported to the bones and teeth, where it is absorbed.
At the same time, Vitamin K2 prevents calcium from being stored in those places where it is not desired, for example, in the arteries and other soft tissues of the body. Vitamin K2 helps keep the arteries clean and at the same time ensures that normal, strong bones are preserved.
Vitamin D3 and K2 work closely together to strengthen the bones and promote the health of the heart and arteries.
