That headline is misleading and alarmist. There are situations where too much vitamin D can cause problems, but you should not stop a prescribed vitamin D supplement solely because of a viral article.
The concern is vitamin D toxicity, which is uncommon and usually results from taking very high doses of supplements over time—not from normal dietary intake or sunlight.
Possible symptoms of excessive vitamin D (often due to high blood calcium levels) include:
- Nausea, vomiting, or poor appetite
- Excessive thirst and frequent urination
- Weakness, fatigue, or confusion
- Kidney problems, such as kidney stones or pain
If you’re taking high-dose vitamin D and develop these symptoms, it’s important to contact your healthcare provider. They may recommend blood tests to check your vitamin D and calcium levels before deciding whether to stop or adjust the supplement.
For most people taking vitamin D as recommended, these symptoms are unlikely to be caused by the supplement. Avoid exceeding the recommended dose unless a healthcare professional has specifically advised it.
