⚠️ Vitamin D: 4 Symptoms That Could Mean You’re Taking Too MuchThe headline “stop taking vitamin D immediately” is too broad. Vitamin D toxicity is rare and usually results from taking excessive amounts of supplements. The main danger is too much calcium in the blood (hypercalcemia).
4 symptoms that deserve attention
- Nausea or vomiting
- Unusual muscle weakness or severe fatigue
- Excessive thirst and frequent urination
- Confusion or difficulty thinking clearly
Other possible effects include poor appetite, constipation, dehydration, kidney stones, and kidney problems.
💊 Don’t automatically stop prescribed vitamin D
If vitamin D was prescribed because you have a deficiency, don’t stop it solely because you experience one of these symptoms. The symptoms have many possible causes. A clinician can check blood calcium and vitamin D levels and determine whether your dose needs changing.
For most adults, 4,000 IU (100 mcg) per day is the established tolerable upper intake level from all sources, although a healthcare professional may temporarily prescribe higher doses to treat deficiency.
