Types of skin

The days are long and bright, the sun is shining and sending more UV rays down onto our skin than ever before. This promotes vitamin D production.

Perfect because the sun vitamin protects against allergies and dementia, lowers blood pressure and puts you in a good mood. Your skin type will tell you how much sun you need and a check to see if you are lacking in vitamin D.

Vitamin D – the sunshine vitamin

“Out in the sun three times a week”

Tolfioow: What is vitamin D anyway?
Prof. Holick: The term vitamin is not entirely correct. This is because it is typically not only taken in with food, as the definition requires, but is mainly formed in the skin as a result of UVB radiation . It primarily regulates calcium and bone metabolism.

How Much Vitamin D Do Healthy Adults Need?
Prof. Holick: Depending on size and weight, around 2000 to 4000 so-called international units* per day. Who has extra needs? Older people and people taking medicines for high blood pressure, muscle disorders or inflammation.

How much vitamin D do we get from food?
Prof. Holick: Only five to ten percent.

So we depend on sunlight.
Prof Holick: Yes. But the skin only produces vitamin D with a UV index of 3 or more. The index shows the intensity of the UV rays – the higher, the more sun vitamin. However, production is suspended from October to March. Then the sun is too flat, so that the UV index is below 3. It is only high enough between 10 a.m. and 3 p.m. from April to September. Then we should expose 20 percent of the body to the sun three times a week.

Who checks my value?
Prof. Holick: Any general practitioner can have the concentration in the blood determined using the “25-OH-D” test.

Does research know anything new about vitamin D?
Prof. Holick: Yes, it lowers blood pressure, strengthens the heart, nerves, airways and immune system, protects against diabetes. The first deficiency symptoms are frequent infections or muscle pain.

*1 IU (international unit) = 0.025 micrograms
