48 year old – white female – live in Kansas – 145 pounds
On 12/21 I had a vitamin D test result of 31 ng/ml. The doctor subscribed 50,000IU taken weekly for 12 weeks. The Pharmacy gave me D2. After four weeks at this dose I felt great; energized, no more aches etc. Then I started having trouble with my stomach/gut and began losing the energy I had gained. I went to a gastrointestinal specialist. He diagnosed me with a bacterial overgrowth in my small intestine. a round of antibiotics helped to relieve these symptoms. After 12 weeks, on 3/24, I have my vitamin D levels checked again. They had risen only 6 points to 36 ng/ml. The doctor told me to take 2000IU of vitamin D a week for 12 weeks then have the test run again. With the warmer weather, I was and continue to be outside much more each day. I continued to get more and more tired until I felt exhausted. After doing some reading on my own, I increase the D3 to 5000IU a day along with 700 of Magnesium. The exhaustion continued and I started having trouble remembering things – perhaps because I was so tired. So they had me take the test again on 6/2 and my levels are no 29 ng/ml – lower than the first test. The doctor suggested that I take the 50,000IU course of Vitamin D for 12 weeks again. I am now having trouble with dizziness – basically feely motion sick.
My concerns/questions: 1) Could it have been the large weekly dose of Vitamin D that caused the bacterial overgrowth? 2) Shouldn't I have seen a larger increase in my ng/ml numbers with the 50,000IU course of vitamin D the first time? and what should I do differently this time to make it more effective? Should we be running other tests to see if it isn't some medical condition causing me to not absorb or process the vitamin D?
3) I purchased the 5000IU of vitamin D gel caps in coconut oil because I read several articles that said it is the only oil that doesn't go rancid and ruin the vitamin D. Is this true and/or useful in anyway? Thank you for your help.
