Recent research revealed that an 89-year-old man in the UK who passed away last year died from an overdose of Vitamin D. This case has raised concerns about the potential consequences of excessive consumption of dietary supplements. Experts are calling for a revision of the packaging regulations for dietary supplements in the country.

Reports suggest that David Mitchner from Surrey in southeastern England died in May 2023 from the effects of Vitamin D poisoning, hypercalcemia, as well as heart and kidney failure. Mitchner had been taking vitamin supplements for at least nine months before his death, and a test conducted before his passing showed a very high vitamin level of 380.

According to Jonathan Stevens, deputy coroner in Surrey, Vitamin D poses „potentially very serious risks and side effects when taken in excess.“

According to current recommendations in the UK, everyone, including pregnant and breastfeeding women, should consider taking a Vitamin D supplement with 10 micrograms daily in the autumn and winter.

How Much Vitamin D Do You Need?

The daily requirement for Vitamin D varies depending on age. In the US, the recommended daily amounts are: 400 IU (international units) for infants up to 12 months, 600 IU for children aged 1-13 years, 600 IU for adolescents aged 14-18 years, 600 IU for adults aged 19-70 years, 800 IU for adults over 71 years, and 600 IU for pregnant and breastfeeding women.

When Do You Need Vitamin D Supplements?

Vitamin D deficiency is associated with a range of health issues, from brittle bones, bone deformities, and muscle weakness to mental health problems such as depression and anxiety. Deficiency in children leads to rickets and in adults to bone pain due to osteomalacia.

Ingesting fortified milk and cereals, as well as consuming Vitamin D-rich foods like fatty fish (salmon, tuna, mackerel), beef liver, cheese, mushrooms, and egg yolks can contribute to increased Vitamin D levels. Additionally, regular sunlight exposure helps to elevate Vitamin D levels.

Some people, especially older adults who are not exposed to sunlight, may have difficulty absorbing Vitamin D. For these individuals, taking Vitamin D supplements after testing for a deficiency can help remedy the deficiency.

What Happens If You Take Too Much Vitamin D?

While it is an essential vitamin, excessive intake can lead to signs of poisoning such as nausea and vomiting, loss of appetite, constipation, weakness, and weight loss. Prolonged intake of excessive Vitamin D can damage the kidneys and elevate blood calcium levels (hypercalcemia), leading to complications like confusion, kidney failure, and irregular heartbeat (arrhythmia).

An overdose of Vitamin D is not achieved through excessive sunlight exposure or consumption of vitamin-rich foods. However, taking excessive dietary supplements can lead to Vitamin D toxicity, also known as hypervitaminosis D.

Treatment for Vitamin D toxicity typically involves stopping Vitamin D intake and limiting calcium intake from food. In more severe cases, doctors may prescribe intravenous fluids and medications like corticosteroids or bisphosphonates.
