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. Most cases of vitamin D toxicity are caused by inappropriate supplement dosing and prescription errors. For example, in a 2020 case report, a 73-year-old man developed vitamin D toxicity after taking 10,000 IU of vitamin D per day for many years 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. Note that 130,000 IU is over 30 times the generally recommended safe upper limit of 4,000 IU per day. Even though toxicity is unlikely if you keep your daily intake levels below 10,000 IU per day and avoid excessively high intakes of vitamin D supplements, experts recommend that people with typical vitamin D levels do not exceed 4,000 IU of vitamin D per day However, make sure to consult a healthcare professional on what dosage you should take. Summary Vitamin D levels greater than 100 ng/mL may be harmful.
