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.

I've been taking 50,000 IU per week of D3 for six months and my level is still low! It went from 19.2 at the beginning to 23.7 now. Is this atypical? What can cause it? I'm wondering if it could mean I have a malabsorption condition.

    Most likely you just need to take more.
    If you weigh more than 150lbs you will need more.
    Do you have a known malabsorption issue such as irritable bowel or Chrohn’s? Have you had weight loss surgery? Some drugs interfere with Vitamin D. Are you sure it’s D3 and not D2? (Prescription in the US is usually D2 and not D3.)
    We do recommend taking Vitamin D on a daily basis. The 50,000iu is about 7000iu a day so you could raise that to 10,000iu a day and see what that does. Oral sprays are suppose to be very effective if you have an absorption issue.
    Depending on how low you were to start, you might still be repairing things and use it up as fast as you take it. Was your level measured as ng/ml or nmol/l?
    Last think I can think of is the actual supplier of the Vitamin D and if the correct amount is in the pill or capsule you are taking.
