    What dosage of vitamin D is safe?

    So many people have a vitamin D deficiency.  There seems to be a discrepancy in how many mg's should be taken.

    I take 1000 IU/ day That's what's listed on the bottle anyways. The bottle says to take one tablet per day. Someone told me in the wintertime to take 2-3 tablets per day. I'm not sure what I should be taking.

    The Weston A. Price Foundation has a lot of information on vitamin D, especially when found in cod liver oil. They say that for the best benefits and least risk are when vitamin A and vitamin D are taken together in a ratio of 10:1. Fermented cod liver oil from Radiant Life Catalog provides this ratio.

    For doses, they say, "recommended dosages for cod liver oil about 500-1000 IU vitamin D for children, 1000-2000 IU vitamin D for adults, 2000-4000 IU vitamin D for pregnant and nursing women and up to 9000-18,000 IU for those taking large amounts of cod liver oil to deal with stress and disease."

    Here's a good source of info http://www.nlm.nih.gov/medlineplus/drug … l/929.html

    Dosage is measured in "IU" - international units- and varies on the reason why you're taking the extra vitamin D.

    The accepted daily maximum seems to be 2000 IU and it is POSSIBLE that taking 4000 IU could be dangerous.

    1000 IU is fairly standard although there are some sources that think this is not enough.

    This article also shows contraindications with various medications i.e. reactions with other drugs that you might be taking.

    Hope this helps :-)

    I've taken as high as 3000IU, and have heard that as much as 5000IU can be taken. Then going down from there, after say a month. This is to load the body with vitamin D3, a loading dose. D3 in a capsule form is more easily assimulated by the body, just D isn't as well utilized. Sunlight on the skin is converted into D3, so if you spend a lot of time outdoors, you may not need as much, as say an office worker. If you live in the North, I would venture to say that you are deficent. If, while taking the higher dose, you notice easy bruising, it may be that your blood is too thin. High doses of D3 should not be combined with coumadin (warfarin), without consulting a doctor. It is best to take D3, with calcium. Some say it can cause toxicity, some say it does not. The signs of toxicity include the following:
    Calcification of soft tissue, frequent thirst, weakness, and loss of appetite.
    Signs of deficiency include rickets, rhemumatic pains, burning mouth syndrome, insomnia, visual problems, and hypothyroidism. The dose most recommended is a 1000 IU.
    A maintenance dose as most refer to it. I don't feel the RDA of 400IU is high enough, unless you live in a warm climate, such as is the case in the South.
