Can taking too much vitamin D3 harm?
Undoubtedly, vitamin D3 30000 plays an important role in the development of muscle cells, the optimal functioning of the innate and acquired immune system, and the preservation of our skeletal muscles. However, taking too much vitamin D will cause vitamin D toxicity in the body.
The doctor recommends taking vitamin D daily, but people often make mistakes and start taking additional doses. Taking vitamin D in excess of the recommended dose leads to Vitamin D toxicity or hypervitaminosis. Due to vitamin D toxicity, other health problems such as heart problems, bone loss, mental health problems, kidney problems, etc. occur.
Symptoms of vitamin D toxicity
With vitamin D toxicity, people show the following symptoms:
- Loss of appetite
- Hallucinations and confusion
- Increased calcium levels in the blood
Vitamin D helps absorb calcium from all the foods you eat. However, if you have a higher vitamin D level, for example due to vitamin D3 50000 IU or vitamin D3 50000 IU daily, your calcium levels in the blood can reach toxic levels and have unpleasant effects. The usual range of serum calcium is 8.5-10.8 mg/dl.
An investigation has shown, that hypercalcemia occurs after taking excessive doses of vitamin D.
Symptoms of an overabundance of calcium
- Frequent urination
- Memory problem
- Pain in the bones
If you are taking vitamin D3 30000 and you feel these symptoms, it means that you have hypercalcemia.
- Altered mental status
Vitamin D toxicity can lead to an altered state of mind in people. They show symptoms such as confusion, psychosis and depression.
In 2021, a case was reportedin which a 64-year-old elderly man accidentally took vitamin D3 50000 IU or 20000 IU per day because he misunderstood the medication instructions. He showed an altered mental 200,000 IU status after a few days.
For the first ten days of his stay in the hospital, he was confused and restless. After 18 days, his serum calcium levels were back to normal.
A study conducted in 2020 showed that a woman who took an average of 130,000 IU of vitamin D per day for 20 months also had symptoms of hypercalcemia.
- Gastrointestinal symptoms
Gastrointestinal is a disease that affects the mouth and stomach. The main cause of gastrointestinal diseases is vitamin D toxicity. In addition, it is most widespread in America.
A current report according to the National Institute of Diabetes and Digestive and Kidney Diseases, about 60 to 70 million people suffer from gastrointestinal diseases every year. That is why it is important to take a limited amount of vitamin D, such as vitamin D 10000.
- Kidney complications
Vitamin D toxicity can lead to kidney damage and kidney failure. As you know, a high level of vitamin D leads to a high level of calcium, which leads to excessive urination and calcification of the kidney.
In addition, a Hypercalcemia leads to vasoconstriction of the renal arteries and reduces their blood supply. That's why doctors recommend not to exceed the recommended amount of vitamin D3. After all, a person can die due to kidney failure.
- Irregular heartbeat and heart attack
Vitamin D toxicity can affect the heart cells and cause cardiac arrhythmias and various other heart diseases. In people with high calcium levels, calcium deposits can form in the arteries or heart valves.

- Bone loss
Vitamin D plays an essential role in bone metabolism and calcium absorption and is necessary for maintaining bone strength.
However, too much vitamin D can affect bone health. Research has shown that high doses of vitamin D can lead to low vitamin K2 levels.
Vitamin K2 is needed to keep calcium in the bones, and not in the blood. And high vitamin D levels can reduce vitamin K2 activity.
How is vitamin D toxicity or hypervitaminosis D toxicity diagnosed?
To diagnose vitamin D toxicity, doctors first interview the patient's medical history. After knowing the symptoms, take blood samples to determine the level of vitamin D, calcium and phosphorus in the body. Some additionally require a urine test to determine the level of calcium in the body.
