According to Hanna Augustin, docent in clinical nutrition at the University of Gothenburg, it is not common for the average Swede to be vitamin D deficient, but it is important to review what you take in during this part of the year.
– The sun contributes during the summer, but during the winter it is through the diet or supplements that we get vitamin D, she says.
Diets rich in vitamin D include fatty fish, dairy products and herbal drinks.
“Don’t know enough”
However, feeling hungover during the darker time of the year does not have to be due to the vitamin D content.
– We don’t know enough to be able to say that vitamin D deficiency makes you tired. You can take a supplement and feel energetic, but possibly it’s a bit of a placebo, she says.
Supplements are suitable for some, but not necessarily for all, and overdoses can be harmful, according to Hanna Augustin.
