Fall and winter are the times when everyone talks about vitamin D, but why is that?

Vitamin D plays an essential role in various processes in the body. It’s important for the proper functioning of your muscles, your bones, as well as your immune system. The body obtains the vitamin via nutrition and it’s a vitamin which is fat-soluble. Not many foods contain the vitamin, however, it is found in fish that is rich in fat, such as eel, salmon and mackerel. Vitamin D is also added to margarine, but that does not affect the daily intake much. Sunlight is the main provider of the daily, necessary dose of vitamin D. The sunrays are weak during the fall and winter months, which results in a lesser production of the vitamin by the body. Next to that, you’ll probably spend less time outside if it’s pouring rain. This is why it’s useful to eat enough fish during these months, and, if necessary, to take a vitamin D supplement.
