In summer, on the other hand, we have been told that we don’t need supplements because we are exposed to more sunlight.
But the Norwegian summer can be moody, to put it nicely. What do you do when the sun is constantly hiding behind clouds, and the rain keeps bucketing down? You stay inside, and cover up in clothing when going out.
And when the sun does come out, you apply sunscreen, which admittedly protects the skin from harmful sunrays, but also prevents it from forming the important vitamine.
This is why it may be wise to take vitamin D supplements in summer too. All year round, simply put.
This is what vitamin D does for you
Vitamin D is good for your teeth and helps you maintain a normal skeleton. Vitamin D also helps your immune system function normally – in other words, it helps you stay healthy.
Vitamin D deficiency is not as widespread in southern countries as it is in Norway. This is probably due to more sunlight in southern countries. However, immigrants with darker skin may find that they need extra vitamin D when they move to the northern countries with less sun.
Elderly people should also be extra aware and make sure they get enough vitamin D, to maintain healthy bones and skeleton.
How to get enough vitamin D
There are not many foods that contain larger quantities of vitamin D. Oily fish, such as salmon, mackrel, herring and trout are some of the foods that you can eat to get vitamin D. You will also find smaller amounts of the vitamin in dairy products that have added vitamin D. If you eat 200 grams of oily fish per day, you will almost get your daily dose of vitamin D. For most people, even a normal, healthy diet will not provide enough vitamin D.
Therefore, many people take a spoonful of fish oil – every day, all year round.
