Don’t stop prescribed vitamin D automatically
These symptoms do not prove that vitamin D is the cause. If you’re experiencing them, contact your doctor or pharmacist, particularly if you’re taking a high-dose supplement. They may check your calcium and vitamin D levels and determine whether your dose needs to change.
For adults, the general upper limit for vitamin D from food and supplements is 4,000 IU (100 mcg) per day, although doctors may temporarily prescribe higher doses to treat a documented deficiency.

Bottom line: Vitamin D is beneficial at appropriate doses, but “more” isn’t better. Don’t discontinue a medically prescribed dose without discussing it with your healthcare professional.
