Hi. I have just read your article about vitamin D insufficiency subsequent to mini-bypass surgery. My wife had the operation 1 or 2 yrs ago, and has just been dx'd with osteoporosis. She has just upped daily dosage of D from 25000 daily to 40000 daily. Due to low absorption of fat, can she increase D concentration orally? If not, what about vitamin D injections? Thank you.

    First of all does she get her vitamin d levels tested and what was her last reading? I think you are trying to say that her vitamin d levels are low and that is why she increased to 40,000 iu but you really did not mean 4000 iu did you?
    Looking forward to your response.

    We generally recommend that an individual should not take more than 10,000 IU/day. Vitamin D toxicity, which leads to too much calcium, generally occurs at 150 ng/ml and after taking one large dose (i.e. 500,000 IU) or from taking around 40,000 IU/day for 3 months or longer.

    Regarding vitamin D injections, as far as we know these are not available in the United States.

    If your wife is having difficulties absorbing vitamin D through oral supplementation, she may want to look into a vitamin D spray, which is absorbed through the cheeks, or a vitamin D sunlamp.

    Since your wife is taking vitamin D for a specific purpose, it is best that she continues to work with her doctor. Especially since she is taking more than 10,000 IU/day, she should work closely under her doctor’s supervision to ensure that the dose she is taking is safe and effective in raising and maintaining her vitamin D levels.
