If you’re referring to a headline like “Pharmacist issues warning to anyone who takes Vitamin D,” the important point is that vitamin D is generally safe at appropriate doses, but more isn’t necessarily better.
Avoid megadosing. Excess vitamin D can cause abnormally high calcium levels, potentially leading to nausea, weakness, confusion, excessive thirst/urination, and kidney problems.
For most adults, the recommended daily intake is 600 IU (15 mcg), increasing to 800 IU (20 mcg) for adults over 70.
The U.S. National Academies’ tolerable upper intake level for adults is 4,000 IU (100 mcg) per day from all sources, unless a healthcare professional recommends otherwise.
Vitamin D can also interact with certain medicines, including some drugs used for kidney disease and other conditions.
If you send me the article/link or tell me the exact vitamin-D dose you’re taking, I can check what the pharmacist’s warning is actually based on and whether it applies to you.
