Vitamin D enters the body in two ways, namely through our diet and through the skin. The one can’t function without the other. Is it necessary to take extra vitamin D? Read about the pros and cons below.
Why should you?
Vitamin D stimulates the absorption of calcium into the blood through the wall of the small intestine. In some cases, you need to have extra vitamin D. For example, for children under four years, the elderly and pregnant women, taking extra vitamin D is recommended, but also for people who get insufficient sunlight. A dark skin colour makes less vitamin D less quickly. During winter, people suffer from a deficiency of vitamin D more easily, because they spend less time outside, cover themselves up more, or because there are less hours of sunshine. This can lead to health problems. The best time for a 'Vitamin D bath' is between 10.00 and 15.00.
Why shouldn’t you?
As soon as the sun shines directly onto your exposed skin, vitamin D is created. The largest proportion of vitamin D enters through the skin. It is therefore more important to go outside more often than to take vitamin D. Vitamin D is also found in foods such as fatty fish, egg yolks and cheese. If you eat a healthy and varied diet and often spend time outdoors in full daylight, then you basically do not need any extra vitamin D. The combination of getting too many ultraviolet rays (via a sun lamp) and swallowing vitamin D supplements can even be dangerous.
Whether or not you need extra vitamin D therefore depends on several factors. An extra walk outside is always good. In addition to getting more sunlight, this will also make you more active.
