Hi, I'm wondering how many IU of Vitamin D my 91-year old mother could take. She has mild congestive heart disease and is currently taking 1000 IU daily but I really wonder if this is enough. Would she tolerate 6,000 IU daily or even more? Thank you for any comments you might have.

    You may like to read http://www.vitamindcouncil.org/health-conditions/congestive-heart-failure/. I have never read anything that states higher amounts of Vitamin D would be bad in this case, ONLY beneficial. (Lack of enough Vitamin D is most likely causing the problem.)
    Does she take ANY medications?
    There are co-factors that go with Vitamin D and you can read about them at http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    No, 1000iu’s is not enough, 5-6000iu would be great. Since I am not a doctor (and
    overly cautious when dealing with others), I would say if possible try 3000iu for a week. If no issues then go to the 5 or 6. Sometimes taking Vitamin D will uncover a magnesium/mineral deficiency. (Sometimes the elderly do not eat very well.) So if she gets any symptoms she should tell you or please check in with her and ask. If she gets any symptoms, come back and tell me what they are.
    I hope you take Vitamin D too!
