Health officials in the UK are advising people who take vitamin D supplements to remain alert to signs of excessive intake, following a rise in reported cases of illness linked to prolonged high-dose use.

The NHS continues to recommend vitamin D supplementation during the autumn and winter months, when reduced sunlight can limit natural production of the vitamin. However, recent safety reviews and medical case reports have highlighted the risks associated with taking doses that exceed established guidance.
