Those who have very little or no sunshine exposure, could be affected throughout the whole year, the health service warns.
People who might be at the risk of lacking this nutrient all year around are those who:
- Are not often outdoors (for example, frail or housebound people)
- Are in an institution like a care home
- Usually wear clothes that cover up most of their skin when outdoors.
If you belong on this list, the Department of Health and Social Care recommends to keep taking a daily supplement even during spring and summer.
