That headline is a bit alarmist—doctors don’t usually tell people to stop Vitamin D unless there are clear signs of too much of it in the body.
Vitamin D is helpful, but in high doses it can lead to Hypervitaminosis D, which raises calcium levels in your blood (a condition called Hypercalcemia).
Here are four symptoms that can signal a problem:
1. Persistent nausea, vomiting, or loss of appetite
Too much vitamin D increases calcium, which can upset your digestive system.
2. Frequent urination and extreme thirst
High calcium levels make your kidneys work harder, pulling more fluid from your body.
3. Weakness, fatigue, or confusion
Elevated calcium can affect your muscles and even your brain, leading to low energy or mental fog.
4. Kidney pain or kidney stones
Excess calcium can build up in the kidneys, sometimes causing stones or damage.
What to do
If you notice these symptoms and you’re taking supplements (especially high-dose ones), it’s smart to:
- Pause the supplement
- Speak with a doctor
- Possibly get a blood test for vitamin D and calcium levels
A quick reality check
Most people don’t get too much vitamin D from food or sunlight—this usually happens from high-dose supplements taken over time.
If you tell me how much you’re taking, I can help you figure out whether it’s in a safe range.
