What is Vitamin D?
Vitamin D, a fat-soluble hormone, is crucial for absorbing calcium and phosphate in the body. The human body primarily produces vitamin D when the skin is exposed to sunlight’s UV rays. Additionally, vitamin D is present in various animal-based foods like egg yolks, fatty fish, and dairy products. It can also be found in mushrooms and in foods that have been fortified with it.
Vitamin D is essential for several bodily functions. It aids in the growth and upkeep of robust bones and teeth, supports muscle function and recovery, and enhances the performance of the immune system.
Where does Vitamin D come from?
Vitamin D can be obtained from various sources, with sunlight being the primary one. While sunlight itself doesn’t contain vitamin D, the body can synthesize it when skin is exposed to the sun’s rays. This synthesis occurs as ultraviolet rays penetrate the skin during sun exposure. Besides sunlight, vitamin D is also available in certain foods, including fatty fish, mushrooms, and fortified products like orange juice, cereals, and some dairy items. However, individuals with limited sun exposure might not produce adequate vitamin D, as it’s challenging to rely solely on dietary sources. This situation is more prevalent in countries with less sunny climates or during winter. To prevent deficiency, it’s beneficial to check vitamin D levels periodically. Potential deficiencies can be treated by by increasing sunlight exposure, adjusting your diet, or taking supplements.
When is a Vitamin D test useful?
Since vitamin D is one of the most common vitamin deficiencies, almost anyone can benefit from performing a test. This is especially true during the winter months, as people often get less vitamin D because it is dark for longer and spend more time indoors. It can also be useful to check your vitamin D level in other seasons, particularly if you do not spend much time outdoors during the day. If you are experiencing symptoms that could indicate a possible deficiency, it is also useful to do a vitamin D test. Gaining clarity about your vitamin D levels can help you get to the root of your symptoms and remedy a deficiency if needed.

What do the results of this test mean?
Vitamin D deficiency:
A vitamin D level that is too low indicates a deficiency. Causes of vitamin D deficiency include inadequate sunlight exposure, a diet low in vitamin D-rich foods, or poor absorption in the intestines. To remedy a vitamin D deficiency, you can increase your sun exposure, enhance your diet with more vitamin-D-rich foods, or consider taking supplements. However, it’s recommended to speak with a doctor before beginning any supplement regimen to establish the appropriate dosage for your needs.
Sufficient Vitamin D:
If your vitamin D levels are sufficient, it means you have enough vitamin D to maintain good bone and overall health. No changes are required at this point, but consider getting tested again in the future if your sunlight exposure, diet, or supplement use changes.
Vitamin D Toxicity:
Too much vitamin D can lead to vitamin D toxicity. When vitamin D levels are excessively high, it can result in an accumulation of calcium in the blood. Typically, vitamin D toxicity arises from taking too many supplements. To address high vitamin D levels, it’s necessary to reduce or halt supplement intake. Consulting with a doctor about your vitamin D supplement usage is crucial to ensure you are not exceeding safe levels.
The recommended daily intake of vitamin D for most people is 10 micrograms. The safe upper limit for vitamin D has been set at 100 micrograms per day.

Elderly people are recommended to receive an extra 20 micrograms per day (Voedingscentrum).
