Too much vitamin D can lead to hypercalcemia (high blood calcium levels), which can cause symptoms such as:
- Nausea, vomiting, or loss of appetite
- Excessive thirst and frequent urination
- Weakness, fatigue, or confusion
- Kidney-related symptoms, including kidney stones or flank pain
Other possible symptoms include constipation, dehydration, muscle weakness, and abnormal heart rhythms in severe cases.
Vitamin D toxicity is generally not caused by normal sun exposure and is rare when supplements are taken at recommended doses. It is more likely when people take high-dose supplements without medical supervision.
If you are experiencing symptoms that could be related to excess vitamin D, the appropriate step is usually to contact your healthcare provider. They may recommend blood tests to check vitamin D and calcium levels before deciding whether to stop supplementation.
If you tell me:
- Your age
- The vitamin D dose you’re taking (e.g., 1,000 IU, 5,000 IU, 50,000 IU)
- How long you’ve been taking it
- Any symptoms you’re having
I can provide more specific information.
