Our body needs a lot of vitamins; if there is a deficiency of them, then we have to face a lot of problems. Similarly, if its quantity increases then it also has serious consequences.

Vitamin D is considered very beneficial for our body. If there is a deficiency of it in the body, then it proves to be very dangerous for us. Like, due to its deficiency, you start falling sick frequently, you start having pain in the bones, along with this you also face problems like depression and mood swings. This is the reason why people start using supplements to maintain their quantity, so that the amount of vitamin D remains in the body. However, this can prove to be dangerous for you in the future. Let us tell you how dangerous consuming more vitamin D than required can be for you.
Why is excess vitamin D dangerous for you?
If you consume supplements to increase its quantity without the advice of a doctor or an expert, then it can cause toxicity. Due to the high quantity, it can later damage your kidney and liver. This is why it is advised to consume it in limited quantities to avoid vitamin D toxicity. Before knowing how it will damage the kidney or liver, let us tell you what vitamin D toxicity means. It means that the amount of this vitamin in the body has become more than required. This situation occurs when people start using it on their own. Sometimes this situation can also arise when you consume more medicine than the prescribed dose. If you continue to consume it continuously, calcium starts accumulating in the blood, which can be serious for you in the future.
What are its symptoms?
You gradually come to know about the increase in the amount of vitamin D in the body over time and by the time you come to know about it, you are unable to recognize its symptoms in time. This can later lead to liver or kidney failure. If we talk about its symptoms, then its main symptoms are as follows:-
- Digestive problems: In this, you start having problems like upset stomach, vomiting, loss of appetite, stomach ache and constipation.
- Kidney and liver damage: If you have kidney or liver problems, you feel the need to urinate frequently, feel thirsty frequently and may have liver damage along with kidney stone problem.
- Pain in bones and joints: You start experiencing pain in the joints of the body. It seems as if there is a lot of pain in the bones.
When is prevention necessary?
If we talk about its prevention, then you should consult a doctor before taking any vitamin D supplement. After examination, take it as per their advice. Generally, the correct amount for an adult is about 600 IU of vitamin D every day.
What does the doctor say?
Senior neurosurgeon Dr. Arun L. Naik explained in his video that people in India start taking vitamin D supplements without testing and consulting a doctor, which increases the calcium level in the body dangerously. This can further cause serious damage to the kidneys, heart and bones. He also said that it is safe to take vitamin D only in the right amount and at the right time, and it should always be taken on the basis of blood test and doctor's guidance.
