    This is one thing I am nervous about. I bought a women's once a day vitamin, even asked the pharmacist at CVS if it's ok to take considering it has 200% of your DV. She said it was totally fine. But I've read that too much vit. D gets deposited in your kidney and can cause stones. So I really don't know what to do.

    It *is* possible to overdose on vitamin D, as excessive amounts of the vitamin can lead to hypercalcemia, which can cause a number of unpleasant symptoms, the most extreme being kidney damage that may not be reversible. This is nearly impossible from diet and sun exposure alone, but can occur with supplements. Vitamin D has lots of beneficial effects (I don't know about weight loss, but it improves immunity and bone health and may play a part in reducing incidence of cardiac disease and cancer), but too much of a good thing is usually a bad idea. I think 10 000 IU is the upper limit of what is recommended for daily intake. Definitely talk to your doctor though if you aren't sure how much you should be taking :smile: I do take a supplement myself but I think it is closer to 500.

    (This information came from lectures specific to Vitamin D as part of a biochemistry course taught by a researcher in this area)

    Thanks SO much for this valuable information! I'm deficient and am taking Viactiv for vitamin D w/calcium but I can see that I'm really falling short of the daily amount I should be taking. I'll boost my supplement accordingly. I do have muscle pain but attributed that to my age (62) -- now I'm encouraged that that might go away, plus my weight loss might increase. Bingo! :-D Again, many thanks!!!!!:flowerforyou:

    I found this to be true for me. Last fall I had blood work done (primarily to monitor my iron levels) and was found to be very deficient with Vitamin D. I was prescribed mega-doses of it (via prescription). This was several months prior to my starting a new healthy lifestyle (such as joining MFP) and was not doing anything special to "fix" my diet or exercise at that time... but I lost about 6 pounds the first month I was taking the supplements (that weight loss is not included in my ticker, by the way).

    My doctor said that vitamin D affects the body more as a hormone does, than as a vitamin.

    I was extremely low on Vitamin D as well and my doctor had me taking 50,000 iu everyday for one month and then 2 x 50,000 twice a month as well as 2,000 iu daily! My doctor said that being Vitamin D deficient can cause many problems such as feeling overly tired and other things I can't remember but I complained of being extremely tired all the time. I don't know if it has helped as I am still taking 2 x 50,000 iu every month and 2,000 iu daily. I will continue to take them so my levels don't dip too low again but as far as losing weight from taking them, I haven't noticed a difference.

    I started taking Calcium + vitamin D a little over a week ago and, even though I lost the same amount this week, I have felt much better throughout the day. I have also been much more awake when I wake up in the morning, which says a lot for me considering it used to take me a good 15 minutes to even think about getting up.

    You definitely have to be careful with any supplements. There is such a thing as too much.....and vitamin D comes in so many different sources.
    Definitely talk to a Dr. or certified nutritionist before starting any diet or supplement.

    No offense, but Doctors get minimal training in nutrition. Less than one course for many of them. Unless they have went out of their way to learn more, many of then likely know less than many people on this site. A nutritionist might be a better choice. The warning about supplements being dangerous resounds among doctors, but their have been so few major incidents of overdose of vitamins especially causing death, that I have to question how dangerous vitamin supplements are. Sure, if you take enough, but that is quite a large dose. Be sensible.

    Thank you for posting about the Dr's. My mom is an RD, and she tells me all the time that the Dr's have to come to her for nutrition information. I would be cautious about a nutritionist though, they don't need a degree. Talk to a registered dietitian....it's the safest bet. They have to take continuing education credits in order to keep their registration, and focus only in nutrition.
