“Stop Vitamin D Immediately If You Have These 4 Symptoms” — What’s Actually True?
This headline is partly misleading. Vitamin D is essential, and most people tolerate recommended doses well. Problems usually occur when someone takes too much supplemental vitamin D, causing calcium levels in the blood to become dangerously high.
🚩 Symptoms that can indicate too much vitamin D
Four important warning symptoms are:
- Nausea or vomiting
- Poor appetite
- Unusual weakness or muscle weakness
- Excessive thirst and frequent urination
Other possible signs include constipation, weight loss, dehydration, confusion, kidney stones and, in severe cases, abnormal heart rhythms or kidney damage.
Should you stop taking it?
If these symptoms develop while you’re taking a high-dose vitamin D supplement, don’t simply assume vitamin D is the cause. Contact your healthcare professional promptly so your vitamin D and calcium levels can be evaluated.
If your doctor prescribed vitamin D to treat a deficiency, don’t permanently discontinue it without discussing it with them. The appropriate dose depends on your blood levels and reason for treatment.
For adults, the usual tolerable upper intake level for vitamin D from food and supplements is 4,000 IU (100 mcg) per day, although doctors may deliberately prescribe higher doses for certain conditions under medical supervision.
