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.

Is there a form of vitamin D that won't give me nausea? I was taking the 3K worth of D that my MD recommended and I started to experience extreme nausea. What good is the D if i throw it up? I feel frustrated since i am also extremely tired many days.

Ask the Vitamin D Council

    Nora the symptoms of hypercalcemia include:

    • feeling sick or being sick
    • poor appetite or loss of appetite
    • feeling very thirsty
    • passing urine often
    • constipation or diarrhea
    • abdominal pain
    • muscle weakness or pain
    • feeling confused
    • feeling tired
    If you have the following symptoms a magnesium deficiency is most likely the reason why:”

    • Irritability or anxiety
    • Nausea
    • Headaches
    • Insomnia
    • Fatigue
    • Muscle cramps/twitching
    • Weakness
    • constipation
    I think you have a magnesium deficiency but a doctor could test your calcium levels while taking the Vitamin D to see if they are high or within range.
    It is very easy to be magnesium deficient. Do you take any magnesium supplements and if so what type of magnesium is it? (Do not rely on magnesium OXIDE, it does not absorb well.) If you think it sounds more like a magnesium deficiency then get some supplements and take them for a week before trying the Vitamin D again.(Woman probably need around 500mg a day or close to it.)
    The following is important reading http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    P.S. We at the Vitamin D Council recommend 5000iu a day and/or a blood level of 50ng/ml.

    BioTechPharmaCal has a tiny Vitamin D capsule that most people can easily accept.
    It carries the Vitamin D in a soft cellulose powder
    You can even cut the caspule in half and dissolve the powder in water
    You can buy these in USA at: http://www.biotechpharmacal.com
    You can buy these in Europe at: http://www.greenvits.eu

    I forgot to say do not take Vitamin D on an empty stomach. First of all it needs fats to absorb better and second it might cause nausea.
