In another, two men took improperly labeled vitamin D supplements, leading to blood calcium levels of 13.2–15 mg/dl (3.3–3.7 mmol/l). In one case study, an older man with dementia who received 50,000 IU of vitamin D daily for 6 months was repeatedly hospitalized with symptoms related to high calcium levels ( 10). The normal range of blood calcium is 8.5–10.2 mg/dl (2.1–2.5 mmol/l). digestive distress, such as vomiting, nausea, and.Symptoms of hypercalcemia, or high blood calcium levels, include: However, if vitamin D intake is excessive, blood calcium may reach levels that can cause unpleasant and potentially dangerous symptoms. In fact, this is one of its most important roles. Vitamin D helps your body absorb calcium from the food you eat. Toxicity symptoms haveīeen reported at extremely high blood levels resulting from megadoses. Ng/ml (250 nmol/l) are considered potentially harmful. Summary Vitamin D levels greater than 100 The woman was admitted to the hospital after she experienced fatigue, forgetfulness, nausea, vomiting, slurred speech, and other symptoms ( 9).Īlthough only extremely large doses can cause toxicity so rapidly, even strong supporters of these supplements recommend an upper limit of 10,000 IU per day ( 3). This was a whopping 47 times the generally recommended safe upper limit of 4,000 IU per day. In one case study, a woman had a level of 476 ng/ml (1,171 nmol/l) after taking a supplement that gave her 186,900 IU of vitamin D3 per day for two months ( 9). Only one person had true toxicity, at 364 ng/ml (899 nmol/l) ( 8). It found that only 37 people had levels above 100 ng/ml (250 nmol/l). One recent study looked at data from more than 20,000 people over a 10-year period. While an increasing number of people are supplementing with vitamin D, it’s rare to find someone with very high blood levels of this vitamin. However, there isn’t agreement on an optimal range for adequate levels.Īlthough a vitamin D level of 30 ng/ml (75 nmol/l) is typically considered adequate, the Vitamin D Council recommends maintaining levels of 40–80 ng/ml (100–200 nmol/l) and states that anything over 100 ng/ml (250 nmol/l) may be harmful ( 6, 7). In contrast, you cannot reach dangerously high blood levels through diet and sun exposure alone.īelow are the 6 main side effects of too much vitamin D.Īchieving adequate levels of vitamin D in your blood may help boost your immunity and protect you from diseases like osteoporosis and cancer ( 5).

It’s also possible to inadvertently consume too much vitamin D by taking supplements that contain much higher amounts than are listed on the label. Importantly, toxicity isn’t common and occurs almost exclusively in people who take long-term, high-dose supplements without monitoring their blood levels.

Because the vitamin is stored in body fat and released into the bloodstream slowly, the effects of toxicity may last for several months after you stop taking supplements ( 4). Vitamin D intoxication occurs when blood levels rise above 150 ng/ml (375 nmol/l). However, taking extremely high doses of vitamin D3 for long periods may lead to excessive buildup in your body.

Studies have shown that each additional 100 IU of vitamin D3 you consume per day will raise your blood vitamin D levels by 1 ng/ml (2.5 nmol/l), on average ( 2, 3). Vitamin D3 has been found to increase blood levels significantly more than D2. Vitamin D3 is produced in response to sun exposure and is found in animal products, whereas vitamin D2 occurs in plants. Supplements are very common, and both vitamin D2 and vitamin D3 can be taken in supplement form. In fact, it’s estimated that about 1 billion people worldwide don’t get enough of this vitamin ( 1). What’s more, most people don’t get enough sun exposure to produce adequate vitamin D. Yet, aside from fatty fish, there are few foods rich in vitamin D.
