Answer From Katherine Zeratsky, R.D., L.D. Treatment includes stopping vitamin D intake and restricting dietary calcium. Your doctor might also prescribe intravenous fluids and medications, such as corticosteroids or bisphosphonates.
This level is many times higher than the U.S. Recommended Dietary Allowance (RDA) for most adults of 600 IU of vitamin D a day. Doses higher than the RDA are sometimes used to treat medical problems such as vitamin D deficiency, but these are given only under the care of a doctor for a specified time frame.
Blood levels should be monitored while someone is taking high doses of vitamin D.

1. Elevated Blood Levels
Hypervitaminosis D is defined as blood vitamin D levels over 100 ng/mL, while vitamin D intoxication is defined as serum levels over 150 ng/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 Even when taking high dose vitamin D supplements, it’s unlikely that a healthy person’s blood vitamin D levels would come close to reaching excessive or toxic levels. 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.
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 Keep in mind that people who are low or deficient in vitamin D typically need to take much higher levels than the current Tolerable Upper Intake Level (UL) of 4,000 IU per day to reach and maintain optimal vitamin D levels. This will help you avoid potential inappropriate or dangerous dosing.
Summary Vitamin D levels greater than 100 ng/mL may be harmful.

Symptoms
vitamin D can cause abnormally high levels of calcium in the blood.
It occurs when you take in too much vitamin D. It’s usually the result of taking high-dose vitamin D supplements. You probably aren’t getting too much vitamin D from the foods you eat or from exposure to the sun. And there has been an increase in overall hypervitaminosis D cases in the past few years.
It is usually due to taking more than the recommended daily value of vitamin D. If you take a multivitamin, look at the amount of vitamin D in it. Some prescription medications used to treat high blood pressure (thiazide diuretics) and heart diseases (digoxin) can cause an increase in vitamin D in the blood.
