Information on the latest vitamin D news and research.

Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

My 93-year-old uncle has had two heart surgeries this year, a stent and a valve replacement. When the valve failed, he was severely dehydrated. He has recovered nicely except that he has some lab values that are slightly out of range. I have tried to get his vitamin D level checked twice, and both times the doctor couldn't figure out how to get it paid through Medicare. Even if I had his level, I am now concerned about the fact that it might not be safe for me to supplement vitamin D. There is a urologist who comes to his town occasionally but don't know if he is vitamin D savy. My question is whether I cans safely supplement with D3 in the face of diminished kidney function? His urea nitrogen is 24 mg/dL (18 is the upper end of the reference range at the lab). His creatinine is 1.20 (1.00 is the upper end). His glomerular filtration rate is 56.44 (needs to be above 60). He is also slightly anemic. The kidney foundations say that someone with kidney disease should not supplement D3 without a prescription). I don't want to take a chance on endangering him, and the doctors are ignorant of the need for D3 to be in the normal range for anything other than osteoporosis. Of course, I could check the 25(OH) level regularly, but I have no idea if the phosphorous and calcium would be normal.

    Well I do not know if this will be helpful at Henry’s website http://www.vitamindwiki.com/Warning+%E2%80%93+Medicare+will+pay+for+just+1+vitamin+D+test+PER+LIFETIME+(if+not+related+to+a+few+diseases)
    Keep in mind I am not a doctor or scientist, I am a member of the VDC.
    I would assume unless your uncle has spent a lot of time outdoors lately in the summer sun with practicaly no clothes on, that he is very deficient after those big surgeries. So I think you can safely assume he is deficient without a blood test.
    His anemia and degradation of his kdney function are probably because of the lack of Vitamin D. You might find reading this helpful http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2878736/. It explains that not all Vitamin D is processed through the kidneys like science use to think but there are receptors all over the human body. So I think the kidney foundation is outdated.
    If it makes you feel better and you cannot find help, then give him Vitamin D slowly meaning work up to 5000iu a day. Start with a 1000iu a day and make sure he gets all the co facotrs needed especially magnesium and K but read about the rest here at http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. Then increase it every week by another 1000 iu. If no out of the ordinary symptoms occur then he will be fine. I think it will only greatly help him! And really taking 5000 iu a day really does not require having to get a blood test to monitor.
    Hope this helps! Anymore questions just ask.
