It is some time since I visited the site and I notice there are comments appearing about unsafe upper levels of Vitamin D3. About a year ago my last blood test was 165.9 nmol/l and my wife was 128.1 nmol/l. This is with 5000 iu D3 daily supplementation and not too much sunlight because we are in the far north. We are both in our late 60s. Are these levels too high and potentially detrimental? What optimum blood level should we be aiming for?

    Jon your blood level of 165 nmol/l equals 66 ng/ml and your wife’s 128 nmol/l equals 51 ng/ml. So you are exactly where you should be as defined by the Vitamin D Council. They are not too high and definitely not detrimental.
    You will have to ignore the “comments” because there is too much research that points to optimum levels of at least 50ng/ml!
