Vitamin D is essential for maintaining healthy bones, normal muscle function and a well-functioning immune system. Research also shows that vitamin D plays a role in many of the body’s functions, including those regulated by hormones. For this reason, maintaining adequate vitamin D levels is an important part of a healthy lifestyle when planning a pregnancy.
In Sweden, vitamin D levels often decrease during autumn and winter because sunlight is not strong enough for the skin to produce sufficient vitamin D. During the summer months, sunlight is the main source of vitamin D, while diet becomes especially important during the rest of the year.
Vitamin D is naturally found in oily fish, eggs and certain mushrooms. In Sweden, several foods, including milk, yoghurt and some plant-based alternatives, are fortified with vitamin D to help people meet their daily needs.
Current research shows that vitamin D is important for normal body functions. However, there is currently insufficient scientific evidence to recommend vitamin D supplements solely to improve fertility in healthy individuals. Preventing vitamin D deficiency remains important for overall health.
A balanced diet, regular time outdoors during the brighter months of the year and following national dietary recommendations are good ways to support healthy vitamin D levels.

Vitamin D is important for your overall health and normal body function. However, current scientific evidence does not show that vitamin D supplements alone improve fertility in healthy people.
