The recommended vitamin D requirement for adults is 15 micrograms or about 600 IU. If not met, a person will experience a vitamin D deficiency which has the potential to cause various he alth problems such as osteomalacia.

Vitamin D is formed in the skin with the help of sunlight. In addition, vitamin D intake can be obtained from food or supplements. Foods rich in vitamin D include salmon, egg yolks, and red meat. However, these foods generally can only provide about 140 IU of daily vitamin D needs.

In order to always meet your vitamin D needs, it is recommended that you get sun exposure between 10 am and 3 pm, and take vitamin D supplements if necessary.

However, excess vitamin D due to the consumption of supplements that do not match the dosage can also cause harmful effects to the he alth of the body.

Dangers of Excess Vitamin D

There are several dangers if you have too much vitamin D, including:

1. Hypercalcemia

Excess vitamin D can cause hypercalcemia. Hypercalcemia is a condition in which the level of calcium in the blood is above average, or higher than 10.8 mg/dL. There are several symptoms of hypercalcemia, including:

  • No appetite
  • Constipation
  • Headache
  • Dehydration
  • Exhaustion
  • High blood pressure
  • Depression

This hypercalcemia can occur when a person takes high doses of vitamin D for a long period of time. If not treated immediately, this condition can be life-threatening.

2. Disorders of the bones

Consuming vitamin D is indeed beneficial for bone strength. However, consuming high doses of vitamin D can actually cause bone disorders.

Research shows that the higher the dose of vitamin D consumed, the higher the risk of fracture. This is because excess vitamin D can interfere with the work of vitamin K2 which helps maintain calcium in the bones, so that the bones lose their density.

3. Kidney damage

Excess vitamin D can cause kidney problems. This is because the consumption of vitamin D in high doses will increase the absorption of calcium, thus causing the formation of kidney stones. In addition, excess vitamin D is also known to cause permanent kidney damage or kidney failure.

4. Digestive system disorders

Hypercalcemia that occurs due to excess vitamin D can cause various digestive disorders. It is usually characterized by nausea, vomiting, loss of appetite, diarrhea, and constipation.

A study shows that taking more than 50,000 IU of vitamin D3 supplements for 3 months can cause diarrhea and abdominal pain. These symptoms subsided after taking vitamin D3 supplements was discontinued.

5. Mental he alth disorders

Not only physically, excess vitamin D can also affect a person's mental condition. Symptoms include depression, anxiety, and confusion, or even coma. A person's mental condition will improve along with a decrease in calcium levels in the body.

This excess of vitamin D usually occurs if you take high doses of vitamin D supplements, not from exposure to sunlight or food. Therefore, make sure to take vitamin D supplements according to your daily needs, not more than 100 micrograms (4,000 IU) for adults.

Actually, eating foods rich in vitamin D and getting at least 15 minutes of sun exposure a day is enough to meet your daily vitamin D needs.

But if your condition doesn't allow you to get vitamin D naturally, you should first consult with your doctor before taking vitamin D supplements. Later, the doctor will determine the dose of vitamin D supplements according to your he alth condition.
