Hi, I found out I had a Vitamin D level of 14 and supplemented for about 6 weeks now. My levels shot up to 79 in that time period. I was taking 10000 iu per day and 15000 twice a week. However, my symptoms are not 100% gone. I thought that once my levels get to an optimal level I would feel better? I am just very frustrated that I cant get along with my daily life. Am I overlooking something? Is this a false reading? Everything I have read says it could take 3-6 months to reach an optimal level! Starting yesterday I am taking 5000 iu per day. Current symptoms are headaches, chest pains (though not as bad) and dizziness.
