2. How can I increase my vitamin D level?

Many people wonder how they can increase their vitamin D levels in the long term. The vitamin is known as the sunshine vitamin. For this reason, it makes a lot of sense to get under the sun for a maximum of 30 minutes a day. The body can produce vitamin D itself with the help of the skin in combination with the sun. Vitamin D is also found in numerous foods. These include fatty fish, avocado, seafood and mushrooms.

What are the functions of vitamin D3 in the human body?

Vitamin D3 is very important for the human organism. The vitamin ensures the maintenance of a normal immune system and utilizes calcium and phosphorus to maintain calcium levels in the blood. The body can absorb vitamin D3 through exposure to sunlight. When UV rays fall on human skin, the body produces vitamin D3 on its own.
Since the human organism can absorb much less sunshine in winter (due to the low level of solar radiation), care should be taken in winter to ensure that one is sufficiently supplied with foods containing vitamin D. Animal foods contain particularly large amounts of vitamin D3. These include, above all, fatty sea fish such as salmon, herring and mackerel. Eggs, butter, margarine and milk also contain moderate amounts of vitamin D3. If you are looking for a plant-based source of vitamin D3, moderate amounts can be found in avocados and mushrooms.

4. vitamin D3 in the form of dietary supplements

Vitamin D3 comes in the form of capsules and tablets. Both forms are easy to use and enter the circulation quickly. However, vitamin D3 tablets are sold in pharmacies, which in many cases contain artificial additives or are made overseas. Vitamin D3 capsules often contain only the active ingredient in a vegetable cellulose shell and can therefore be produced without fillers. In general, it should always be ensured that the product has been produced in Germany in order to guarantee a consistently high preparation quality.

5. conclusion: How much vitamin D per day is reasonable?

An adult should take about 4000 IU of vitamin D3 a day. The human body can produce vitamin D3 itself with the help of the skin. Of course, sunlight is very important for this. Furthermore, a diet with foods containing vitamin D3 can be very helpful. These include fatty fish and avocado, for example.
