Headlines like “Stop Taking Vitamin D Immediately If You Have These 4 Symptoms” are often simplified or sensationalized.
The real concern is usually vitamin D toxicity, which is uncommon and typically occurs from taking very high doses of supplements for a prolonged period. Excess vitamin D can cause high blood calcium levels (hypercalcemia).
Symptoms that may warrant prompt medical attention and a discussion with your healthcare provider include:
- Persistent nausea, vomiting, or loss of appetite
- Excessive thirst and frequent urination
- Weakness, fatigue, or confusion
- Kidney-related symptoms, such as flank pain or signs of kidney stones
Other possible symptoms of vitamin D toxicity can include constipation, abdominal pain, muscle weakness, and irregular heart rhythms.
It’s important not to stop a prescribed medication or supplement solely because of a headline. Many of these symptoms can have causes unrelated to vitamin D, and the appropriate response depends on:
- How much vitamin D you’re taking
- How long you’ve been taking it
- Your blood vitamin D and calcium levels
- Your medical conditions and other medications
