Health Risks from Excessive Vitamin D
Health Risks from Excessive Vitamin D
- Vitamin D toxicity can cause nonspecific symptoms such as nausea, vomiting, poor appetite, constipation, weakness, and weight loss.
- More seriously, it can also raise blood levels of calcium, causing mental status changes such as confusion and heart rhythm abnormalities.
- The use of supplements of both calcium (1,000 mg/day) and vitamin D (400 IU/day) by postmenopausal women was associated with a 17% increase in the risk of kidney stones over 7 years in the Women’s Health Initiative . Deposition of calcium and phosphate in the kidneys and other soft tissues can also be caused by excessive vitamin D levels .
- A serum 25(OH)D concentration consistently >200 ng/mL is considered to be potentially toxic . In an animal model, concentrations ≤400 ng/mL were not associated with harm .
