Vitamin D warning – Taking too much of the supplement can cause deadly condition

Vitamin D is needed to help the immune system work properly, and to aid development of bones and teeth.

The vitamin could also reduce the symptoms of depression and boost weight loss.

The NHS recommends that adults take a daily 10mcg supplement of vitamin D to raise nutrient levels during the winter months.

But, taking too much of the vitamin can have devastating consequences.

“Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body [hypercalcaemia],” said the NHS.

“This can weaken the bones and damage the kidneys and the heart.

“If you choose to take vitamin D supplements, 10mcg a day will be enough for most people.

“Don't take more than 100mcg of vitamin D a day as it could be harmful.”

Children aged one to 10 years old shouldn’t take more than 50mcg of vitamin D a day.

Infants under 12 months shouldn’t have more than 25mcg a day.

Hypercalcaemia can lead to mild cognitive impairment, constipation and muscle weakness.

At its worst, the condition can cause abdominal pain, cardiac arrhythmias, comas, and even deadly pancreatitis.

Most people get enough vitamin D from sunlight during late spring to early autumn.

You can get extra vitamin D from oily fish, including salmon, sardines, tuna and mackerel.

Other sources of vitamin D include red meat, liver, egg yolks and some breakfast cereals.

Meanwhile, rheumatoid arthritis symptoms could be prevented by taking vitamin D supplements, researchers have claimed.
