The headline “Stop taking vitamin D immediately if you have these 4 symptoms” is often written to sound alarming. Vitamin D is important for bone health, muscles, and immune function, but taking too much vitamin D can cause problems, mainly because it can raise calcium levels in the blood.
Possible signs of excess vitamin D (vitamin D toxicity) may include:
- Nausea, vomiting, or loss of appetite
- Unusual thirst and frequent urination
- Weakness, fatigue, or confusion
- Constipation or abdominal discomfort
High doses over a long period are the usual concern; normal recommended amounts are generally safe for most people.
If you take vitamin D and develop these symptoms—especially if you use high-dose supplements—contact a healthcare professional before taking more. A blood test can check vitamin D and calcium levels.
Do not stop a vitamin D prescription without medical advice, especially if it was prescribed for a documented deficiency.
