Doctors have issued a warning to those who take high doses of vitamin D.<\/p>\n

Vitamin D is a hugely beneficial supplement. Not only does vitamin D aid with the growth and development of bones and teeth, but it’s also been found to reduce the risk of certain diseases<\/a>.<\/p>\n

Research<\/a> suggests that vitamin D may reduce the risk of multiple sclerosis; decrease the chance of heart disease and reduce the likelihood of severe illness.<\/p>\n

It’s also been found to support immune health, with those having lower than adequate levels of vitamin D also being potentially more at risk of infection and autoimmune diseases.<\/p>\n

It’s certainly a vitamin that you’d want to be on top of, but experts are also warning people about the potentially severe risks of overdosing on vitamin D.<\/p>\n

In a BMJ Case Report<\/a>, one man needed hospital admission for his excessive vitamin D intake.<\/p>\n

The man<\/a>, reported as middle-aged, was referred to hospital after he began suffering with vomiting, nausea, abdominal pain, leg cramps, tinnitus, dry mouth, increased thirst, diarrhoea and weight loss.<\/p>\n

The concerning symptoms had been ongoing for three months, but began around four weeks after he started taking increased vitamin D supplements.<\/p>\n

He already had existing health issues, including ‘tuberculosis, an inner ear tumour (left vestibular schwannoma), which had resulted in deafness in that ear, a build-up of fluid in the brain (hydrocephalus), bacterial meningitis, and chronic sinusitis’.<\/p>\n

The report explains how doctors discovered he had been taking more than 20 supplements every day.<\/p>\n

These were: vitamin D 150,000 IU; vitamin K2 100 mg; vitamin C; vitamin B9; vitamin B2; vitamin B6, omega-3 2000 mg twice daily as well as other supplements.<\/p>\n

Although the man had stopped his vitamin regime when his symptoms started, he was still suffering and decided to visit the doctor.<\/p>\n

Blood tests revealed high levels of calcium and a vitamin D level seven times the sufficient level required.<\/p>\n

Kidney function tests also revealed acute kidney injury, meanwhile scans ruled out any serious conditions such as cancer.<\/p>\n

\u201cGlobally, there is a growing trend of hypervitaminosis D, a clinical condition characterised by elevated serum vitamin D3 levels,\u201d write authors.<\/p>\n

\u201cGiven its slow turnover (half-life of approximately 2 months), during which vitamin D toxicity develops, symptoms can last for several weeks.<\/p>\n

\u201cThis case report further highlights the potential toxicity of supplements that are largely considered safe until taken in unsafe amounts or in unsafe combinations.\u201d<\/p>\n

The man ended up staying in hospital for eight days, but even two months after discharge, his vitamin D levels were still abnormally high.<\/p>\n

The report warns that symptoms of hypervitaminosis D can include: drowsiness; confusion; apathy; psychosis; depression; stupor; coma; anorexia; abdominal pain; vomiting; constipation; peptic ulcers; pancreatitis; high blood pressure; abnormal heart rhythm and kidney issues.<\/p>\n","protected":false},"excerpt":{"rendered":"Doctors have issued a warning to those who take high doses of vitamin D.
