I'm a female, age 62. How much vitamin D suppliment should I be taking?
I live in Napa Valley in California. My doctor says I need a vitamin D supplement but hasn't suggested the optimum amount.
The Food and Nutrition Board at the Institute of Medicine of The National Academies considers an adequate intake of Vitamin D for women 51 - 70 to be 400 IU (10 mcg). However, there have been many questions as to whether that is sufficient for most people, especially as they get older. And if you have a deficiency of Vitamin D, you would probably need a higher dose. The upper limit recommended is 2,000 IU as toxicity can occur at higher doses.
It would be a good idea to call your doctor and ask what dosage he recommends since he apparently recommended it for a specific reason. With most doctors, you can call the office and leave a message with their nurse, who should call you back with an answer within 24 hours.
I hope that helps.
