Covid-19: Advice, Updates And Vaccine Options
Vitamin D toxicity, also called hypervitaminosis D, is a rare but potentially serious condition that occurs when you have excessive amounts of vitamin D in your body. That’s because your body regulates the amount of vitamin D produced by sun exposure, and even fortified foods don’t contain large amounts of vitamin D.
The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Treatment includes stopping vitamin D intake and restricting dietary calcium.
Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. Review/update the information highlighted below and resubmit the form. Email ErrorEmail field is required ErrorInclude a valid email address Learn more about Mayo Clinic’s use of data.

1. Elevated Blood Levels
In order for vitamin D to reach toxic or dangerous levels in the body, it needs to exceed 100 nanograms (ng) per mL.
Recommendations on optimal vitamin D levels vary, but research suggests that levels between 30–60 ng/mL are likely optimal and may help protect against illness and disease In another 2020 case report, a 56-year-old woman who took an average of 130,000 IU of vitamin D per day for 20 months in hopes of improving symptoms of multiple sclerosis was hospitalized for symptoms including nausea, vomiting, and muscle weakness. Her vitamin D levels were discovered to be 265 ng/mL Note that 130,000 IU is over 30 times the generally recommended safe upper limit of 4,000 IU per day. Summary Vitamin D levels greater than 100 ng/mL may be harmful. Toxicity symptoms have been reported at extremely high blood levels in cases where people took megadoses (very high doses) of vitamin D supplements for extended periods of time.

People at high risk of not getting enough vitamin D, all children aged 1 to 4, and all babies (unless they’re having more than 500ml of infant formula a day) should take a daily supplement throughout the year. Information: There have been some reports about vitamin D reducing the risk of coronavirus (COVID-19). But there is currently not enough evidence to support taking vitamin D solely to prevent or treat COVID-19.
