What it is for

  • Vitamin D

    Why people check it

    Vitamin D comes from food and supplements, and is also made in the skin when it is exposed to sunlight. In the UK, up to a quarter of people are low in vitamin D by the end of winter. Low vitamin D can weaken bones and muscles, raise the risk of fractures and affect the immune system.

    Can be done with a finger-prick kit at home, at a collection point or with home collection on request.
