Ergocalciferol for Vitamin D Deficiency "I’ve been feeling tired and weary for months now. I have severe reflux, dysphasia, and GERD. Dairy allergy. I had a flare-up and ended up cutting ALL dairy (I still ate a small amount at times), but since then I figured the fatigue must be a vitamin deficiency. And I was right, my vitamin D level was 15. I started my 50,000 once-a-week vitamin D2 yesterday at 3 pm. No symptoms then, but couldn’t fall asleep until after 1:00 am. It is now the 2nd day, and I started having a lot of diarrhea around 10:00 am. And getting tired again. Praying no other side effects. I hope everyone hangs in there, I know it’s frustrating. My husband doesn’t understand just how awful I feel being vitamin deficient, and no one does until they go through it. I know you guys don’t feel the best, but hang in there, and if you have any strange side effects, reach out to your doctor to make sure you get good advice. To those feeling better - so happy for you guys !!!"

For Vitamin D Deficiency "I'm heartened to read many positive experiences. For those who have had extremely poor reactions, I hope you find a remedy. I've been ill for so long, it's become normal. I got used to being (literally) sick and tired; sinus headaches more often than not since November 2017. I've been focused on this, blind to everything else. A quick checkup, at which I mentioned always being fatigued, non-restorative sleep, and that the symptoms of fibro resonate with me. I'm not a hypochondriac. I couldn't stand the idea of feeling this way. I was happy when this enormous dose of vitamin D was prescribed. I have yet to speak with my PCP. This supplement has made me feel less tired, more hopeful, and less foggy/spacey. I'm quite pale; the sun runs rampant on my skin. Yes, I do go outside. Much less often than the average bear, I guess. I'm also extremely photosensitive. I hope this works and am anxious to see the results of the recent blood test."

Ergocalciferol "I've been taking D2 50,000 IU once a week for 5 weeks. NP put me on it for osteoporosis. Side effects include fatigue, swollen lower legs, dry mouth, loss of appetite, severe drowsiness, and irritability. I told her I would try it, and so I did. However, with all these side effects, I will not continue to take it."

For Vitamin D Deficiency "My doc prescribed the 50,000 per week vitamin D pill for vitamin D deficiency. I took it 1 time and never took it again. It made me feel terrible! Headache, fatigue, nausea. I just went to bed after I took it that day, so I could sleep off the effects. I've been on 4,000 per day for over 2 years now, and I do just fine with that, but my vitamin D levels are still under the normal range."
