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.

Over a year ago I began to feel extremely tired, breathless and was struggling to do simple tasks such as walking up the stairs (I am 37 and healthy). I was diagnosed with severe vitamin D deficiency and took 50,000iu once a week for four months. I felt a bit better after 3 months, and tested normal. 3 (summer, spent outside with the kids) months later my vitamin D is below traceable and I can't even move some days!!! Another course of vitamin D and no improvement on testing. I feel so awful, can't exercise, can't lift, if I Hoover a room I can't get out of bed the next morning. I'm now taking 6,200iu per day. Why is my body not improving and not retaining the vitamin D? I've been tested for thyroid, H2C, hormonal imbalances and lymphoma, iron etc but they're not finding anything. Should a person feel so weak just because of vitamin D deficiency, and how much should I take per day to feel better? I'm at the point where I am getting seriously depressed from it (never had stress or depression before) because I can't look after my home and my kids properly. Thank you.

    If you “hoover a room” do you live in the UK or somewhere else?
    Was either one of those 50,000iu treatments D3 or were they D2?
    Like most people, I feel you are under the impression that if you take the “treatment” you never have to take any Vitamin D again. It’s not how Vitamin D works it needs to be constantly replenished with either supplements, sunshine or the correct tanning bed/light. Foods do not contain enough Vitamin D for the human body.
    If you do live in the UK you can only make Vitamin D from sunshine during the summer. Are your children very young? Do they get any Vitamin D supplements? If not I guarantee they are deficient in the winter also. (This deficit will really start to show when they hit puberty if not before.) This is a world wide epidemic. Even those living in India are deficient.
    The 50,000iu divided by 7 is about 7000iu a day. I would bump that to 8000iu a day. The “official”l safe upper limit is 10,000iu a day.
    You absolutely need to read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. All of these cofactors are important.
    I will warn you, if you do not take/have enough magnesium or calcium in your system, the vitamin D will cause symptoms. (Typical blood tests of these minerals will not show a deficit or a least a deficit that will then start giving you symptoms.) I think doctors, when treating extremely low Vitamin D levels, are suppose to at least tell you to take calcium and I am finding they are not.

    Thank you very much. I am taking D3, and have now bumped it up to 8000iu per day, and have started to take magnesium and calcium, too. Yes, I’m in the UK. My youngest daughter has a chronic illness, so she gets a very comprehensive vitamin. My other two take a supplement containing vitamin D every day.

    I should have said in my original reply that we here at the VDC recommend achieving a healthy blood level of a minimum of 50ng/ml (125nmol/l). Maintaning a level below 40ng/ml (100nmol/l) increases your chances of cancer and other diseases.For an adult of average weight of 150lbs, that means taking 5000iu a day as a maintenance dosage. Children should be given 1000iu for every 25lbs of body weight.
