Vitamin D is a very important compound for the health of the body. Research suggests that vitamin D is particularly necessary for muscle cell growth, proper functioning of the immune system, and maintenance of the skeletal system.
With the increasing incidence of vitamin D deficiency, people are turning to taking supplements to reach normal levels. However, many people do not realize that overdosing on vitamin D supplements does more harm than good.
Vitamin D toxicity, or hypervitaminosis D, is a rare but potentially serious condition that frequently occurs when there is too much vitamin D in the body. According to doctors, vitamin D toxicity is usually caused by taking high doses of vitamin D supplements.
Some signs of high vitamin D levels are:
- Anorexia
- constipation
- dehydration
- Malaise
- Frequent urination
- high blood pressure
- muscle weakness
- nausea
- thirst
- vomiting
Call your doctor right away if you have any of these symptoms and tell them about any supplements, drugs or substances you are taking, including the dosage.
Other serious signs of excessive vitamin D levels you should be aware of are:
Hypercalcemia: Too much vitamin D can lead to excess calcium in the blood. This condition is called hypercalcemia.
Kidney problems: Excess vitamin D can also cause kidney problems and kidney damage.
Bone problems: Getting enough vitamin D is essential for bone health, but too much can actually harm you. Studies have shown that people who take large amounts of vitamin D are more prone to bone fractures.
How Much Vitamin D Does Your Body Need?
According to the Cleveland Clinic, a healthy daily vitamin D requirement is:
People aged 19-50: 600 IU/day.
People aged 50-70: at least 600 IU/day.
People over 70: at least 800 IU/day.
The recommended maximum daily requirement is 4,000 IU/day for healthy adults.
Talk to your doctor about the right dose for you. If you take a vitamin D supplement, you should have regular blood tests to check your vitamin D levels. Always consult your doctor before starting supplements.
