If you’re referring to the headline “Pharmacist issues warning to anyone who takes Vitamin D,” the warning has a legitimate point, but the headline is misleading.
What you actually need to know
Vitamin D is important for bone health, calcium absorption, and muscle function, and appropriate supplementation is generally safe. The main concern is excessive supplementation, particularly high doses taken for long periods. The adult upper intake limit is 4,000 IU (100 mcg) per day unless a healthcare professional is supervising a higher therapeutic dose.

Too much vitamin D can raise calcium levels and potentially cause nausea, vomiting, weakness, excessive thirst or urination, confusion, kidney stones, kidney damage, or abnormal heart rhythms.

People with kidney disease, kidney stones, or problems with calcium levels may also need individualized advice.
Should you stop taking vitamin D?
No—not simply because of this warning. If vitamin D was prescribed for a deficiency, don’t stop it without discussing it with your clinician. Doctors sometimes deliberately use higher doses for a limited period to correct severe deficiency.

Bottom line: The sensible message isn’t “vitamin D is dangerous.” It’s “avoid unnecessary high doses and check for medication interactions.” If you tell me your vitamin D dose (IU) and any medications you’re taking, I can check the combination for you.
