Doctors have warned people not to take too many vitamin D supplements after a man needed eight days of hospital care because he overdosed.

The middle-aged man had been experiencing symptoms including vomiting, nausea and leg cramps for three months when his doctor referred him to hospital for treatment.

He also experienced tinnitus, dry mouth, weight loss, increased thirst and diarrhoea.

Doctors said the overdose condition - called hypervitaminosis D - is increasing, though is still uncommon.

The man's daily regime had included more than 20 over-the-counter supplements. As part of this, he was taking 50,000mg of vitamin D - the daily requirement is 600mg.
