For Vitamin D Deficiency "I was feeling fine until I was diagnosed with vitamin D deficiency (4.6). I took 8000 IU of vitamin D3 once a week for a month. The first time I took it after 3 hours I felt sick all of a sudden, with terrible palpitations, extreme dizziness, nausea, and confusion. I thought I was dying! My doctor said it was impossible vitamin D caused this, so he told me to keep taking the drug. The second week I ended up in the ER, but everything was negative, and they told me it couldn't be vitamin D. I took it 4 times, once a week, until I asked my pharmacist about my symptoms, and he told me to stop immediately. During that month I had constipation, loss of appetite, extreme weight loss, dizziness, fatigue, muscle pain, anxiety, depression, high blood pressure, and scary palpitation episodes (10 times), all symptoms I never had before. Now it's been a month since I've stopped taking vitamin D, and my health is slowly improving. Now my vitamin D level is 16, so I guess the drug worked, but I would never take it again with all those side effects."

For Vitamin D Deficiency "I was advised to take 2,000 IUs of cholecalciferol daily after being diagnosed with a vitamin D deficiency. About 6 hours after my first pill, I noticed my heart was racing, and I started having palpitations. Then the anxiety set in. At this point, I didn’t make the connection with the cholecalciferol, but after continuing to take it over the following days, the anxiety turned to absolute sweaty panic and dread, as well as insomnia. By day 4, I was horribly depressed, had no appetite, and was nauseous. I don’t think my doctor believed me when I told her the cholecalciferol was causing this, but I know that’s what it was. I later learned that cholecalciferol creates serotonin in your brain by increasing the enzyme tryptophan hydroxylase 2. If you get too much serotonin, you develop serotonin syndrome - and my experience aligned exactly with the symptoms of serotonin syndrome. Hopefully, this is helpful to others. For now, I’ll just keep my vitamin D deficiency."

For Vitamin D Deficiency "30/10/2020 prescribed 400,000 IU for ten days, 20K once weekly for six more weeks. After 10 days of the 400K severe colon pain, chronic bloating, alternating between diarrhea and constipation, so it was like the symptoms of IBS or bowel cancer. I had nerve pain, bone pain, severe back pain, chronic stress, depression and anxiety, weakness, exhaustion. The doctor denies any possible connection with vitamin D and suggested IBS. Then after a full blood count, suggested diverticulitis. And suggested I need to address my state of mind as opposed to the body. Now four months later, I am just about starting to feel slightly better."
