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.

My daughter had type 1 diabetes diagnosed 6 mos ago. After one month she began having other symptoms – hair loss, low grade fever, headaches, nighttime twitching. Blood work in September showed normal Vitamin D levels. For the past 2 weeks she has had low grade fever and fatigue. Her blood work came back this week and showed she is Vitamin D deficient and everything else normal on cbc. Could she become deficient that quickly? Can these other symptoms be attributed to the deficiency? She eats well, takes a multivitamin, is on the beach most days in summer and goes outside regularly.

    So the simple answer is “yes” she can become deficient that fast. Vitamin D depends on latitude, time of year, color of skin, time of day, how long you spend outside and amount of skin exposed. The so called “normal” levels she had in September may have been in the range of 20-30ng/ml and studies and information show us that everyone needs a level of 50ng/ml and above to be and stay healthy. So that is why we promote 50ng/ml and above here at the VDC.
    As for the symptoms of hair loss, low grade fever, headaches, and nighttime twitching. Vitamin D is used a lot to keep our immune system working properly so that may account for “fever”. Low D is also attributed to headaches. Some people have reported hair improvement while taking D but sometimes hair loss can come from hypothyroidism. Low Vitamin D can cause autoimmune attacks on your thyroid thus causing the hypothyroidism. As for the twitching, I assume you mean muscles and muscles use a lot of Vitamin D to function properly. (She may also be low on magnesium and this is not shown on a regular blood test.)
    You may want to read http://www.vitamindcouncil.org/health-conditions/ and read about type 1.
    MOST importantly is how are they treating her deficiency. I hope they are giving her D3 and not D2. Since I do not know how low her levels were or how old she is or what she weighs, I hope they are giving her a MINIMUM of 1000iu D3 for every 25lbs of body weight. Everyone also needs Vitamin D’s co-factors so please read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    If you have more questions, just ask.
