What is vitamin D?
Vitamin D is an essential vitamin responsible for many functions in the body. It helps absorb and utilize calcium and phosphorus to promote strong bones and teeth. But that’s not all. Vitamin D is also important for the immune system, muscle function, hormone regulation and even mood.
There are two types of vitamin D: D2 and D3. D2 is found in plant sources, while D3 is made in animal sources and through synthesis with sunlight. If you do not get enough sun exposure or eat a vegan diet, you may not be getting enough vitamin D. In this case, a vitamin D supplement can help meet your needs.
How can you determine your vitamin D level?
To find out if you need a vitamin D supplement, you need to determine your vitamin D level. The easiest way to do this is to have your blood tested by a doctor. There, your blood will be tested for vitamin D content and you will receive a result in ng/ml. A value between 30 and 100 ng/ml is considered sufficient.
If your level is below that, vitamin D supplementation may be useful to compensate for your deficiency. However, you should not take high doses on your own, but seek advice from a doctor. Overdosing on vitamin D can lead to undesirable side effects.
How much vitamin D do you need?
When it comes to the question of how much vitamin D you need, you should consider your individual needs. Several factors come into play, including your age, gender, lifestyle, and where you live. In general, it is recommended that adults between the ages of 18 and 64 consume 600-800 IU (International Units) of vitamin D daily.
The requirement may be higher for older people and pregnant women. It should be noted that vitamin D cannot be obtained only from food. The body also produces it through sunlight on the skin. However, especially in the winter months or for people who spend a lot of time indoors, an additional intake can be useful.
How does a vitamin D deficiency manifest itself?
If you often feel tired and listless, this could be a sign of vitamin D deficiency. Frequent infections and a weakened immune system may also indicate it. Other symptoms can include muscle and bone pain, hair loss and depression. Deficiency can be especially prevalent in the winter months, when the sun shines less and we spend less time outdoors.
If you are unsure if you are consuming enough vitamin D, you should consult a doctor and consider taking a vitamin D supplement if necessary. At this point, it is important to emphasize that vitamin D is not only important for our bones and muscles. It also plays an important role in regulating the immune system and thus can protect against many diseases. Studies have shown that adequate vitamin D levels can reduce the risk of cardiovascular disease, diabetes and cancer.
But how can we increase our vitamin D levels naturally? The best source of vitamin D is the sun. If possible, we should spend at least 15 minutes a day in the fresh air – preferably at midday, when UV radiation is at its highest. Certain foods also contain small amounts of vitamin D, e.g. fish (salmon, herring), eggs or mushrooms. However, this is often not enough to cover the daily requirement.
In some cases, it may be useful to take additional vitamin D – for example, in older people or people with dark skin, as their body’s own production is lower than in fair-skinned people. But be careful. An overdose of high-dose preparations should be avoided!
What alternatives are there to absorb more vitamin D?
Besides taking vitamin D supplements, there are other ways to increase vitamin D levels. One way is to spend more time in the sun. Your body produces vitamin D when your skin is exposed to the sun. However, you should be careful not to stay in the sun too long and to protect yourself adequately to avoid skin damage.
Another option is to change your diet and eat more foods containing vitamin D, such as fish, eggs and mushrooms. Dairy products and fortified foods can also be a good source. Another way to increase vitamin D levels is to use daylight lamps. These lamps emit UV rays similar to those of the sun, and can thus support the body’s vitamin D production.

What are the risks of vitamin D overdose?
Overdosing on vitamin D can pose serious risks to your health. If you take too much vitamin D, it can cause hypercalcemia, which is an increase in the level of calcium in your blood. This can lead to a number of symptoms, including nausea, vomiting, constipation, weakness, and fatigue. In severe cases, hypercalcemia can also lead to kidney stones, kidney failure and damage to the cardiovascular system.
Following the recommended vitamin D dosage is critical, as is avoiding self-medication and overdose. If you are unsure whether you need a vitamin D supplement, seek advice from a physician or nutritionist.
Can you buy a vitamin D supplement over the counter and take it yourself?
Wondering if you can buy and take vitamin D supplements yourself? The answer is a resounding yes! Vitamin D is a dietary supplement and can be taken without a doctor’s prescription. However, it is advisable to consult a doctor before taking it to make sure that you really have a vitamin D deficiency and that the supplement is suitable for you. An overdose can have negative effects. So, before acting on your own authority, be sure to seek the advice of a doctor.
