Hi, I got my blood report today and I noticed that I have a vitamin D level of 6.75 ng/ml. Before this I never took any blood test. I also saw THYROID STIMULATING HORMONE (TSH) 6.38 μIU/ml which is more than the healthy Range mentioned in the report. Now I want to know which Vitamin D I should take.. D2 or D3 and How much Unit? I am overweight I gained 18kg in just last 2yrs and It is making my life hard both on Physically and Emotionally..! M, 26yr, 88KG, 5'6"

    Never take D2 ONLY D3. Your Vitamin D level is extremely low. Has a doctor even offered to try and treat you?
    You need to read this it is very important http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. The only thing it does not talk about there is calcium. Since your level is so low, below 10ng/ml, it may be prudent to also take some supplemental calcium. (At levels that low you could have Osteomalacia and your bones may need a lot of minerals to repair.)
    Under these circumstances, I would start with 1000iu for every 25lbs of body weight. This means you would take 10,000iu (ten thousand) a day of D3. (Being overweight “dilutes Vitamin D3.)
    The only way to truly know if your levels are increasing, is to get another blood test in about two months to make sure your levels have increased and by how much. We recommend reaching a minimum healthy level of 50ng/ml.
    Vitamin D3 should only make you feel better and not worse or give you added symptoms. If it does you need to come back and tell me. Also I do not know if the 10,000iu will be enough.(If you can come back and tell me how you are doing in a month or two!)
    Your TSH is high. I have already seen one person’s TSH decrease (decreasing being a good thing) when they took Vitamin D.
    Let me know if you have any more questions.
