Dietary supplements with vitamin D and K
Vitamin D is a fat-soluble vitamin that is formed in our skin by the influence of sunlight. This vitamin is present in our diet to a limited extent only and can mainly be found in dairy products and fatty fish.
The recommended daily intake is 10 micrograms of vitamin D. People who are over 70 years old should increase their intake up to 20 micrograms of vitamin D.
Vitamin D affects many processes in our body. For example, it plays an important role in the normal absorption of calcium and is therefore very important for the development of our bones. Vitamin D is also related to the normal functioning of our immune system. Research even shows that a vitamin D deficiency may be responsible for a decrease in the serotonin levels. Serotonin deficiency can lead to sleep problems and depression, among many other things. A insufficient intake of vitamin D can thus cause various issues.
Although a lack of sunlight is the main cause of a vitamin D deficiency, a balanced diet may also contribute to preventing a deficiency. When eating a sufficient amount of food that contains vitamin D, you are able to reduce the deficits that may occur due to a lack of sunlight.
Vitamine K is a fat-soluble vitamin that is very important for an optimal blood coagulation in the body. This vitamin may also play a role in the bone production. Vitamin K can mostly be found in green leafy vegetables, meat, eggs and grains.
The recommended daily intake of vitamin K1 is 70 micrograms for adults from the age of 18.
