For Vitamin D Deficiency "I recently started taking the 50,000 IU Vitamin D prescribed by my doctor for Vitamin D deficiency last week. I was very fatigued, experienced muscle cramps, pain, and just felt really bad for a while now. Finally, I went to the doctor about it, and he ran a bunch of blood work. It turns out that my Vitamin D level was 12, which is very low. I have also suffered from depression and anxiety for years, but more recently, in the past year, it's been worse than usual. Since I've taken 2 doses so far, 1 per week, I have noticed a marked improvement in all my symptoms! My energy level is a little better, my anxiety and depression have lifted quite a bit, and my muscle pain and cramping are improving! I am shocked by how much being low on Vitamin D really affects you. I'm hoping the feeling better continues! I am supposed to take 1 per week for 12 weeks and then recheck. Anyway, so far so good! Oh, and I have not had any side effects that I've noticed."

For Vitamin D Deficiency "This D2 saved my life. I was having so many problems with my digestive issues, acids, bloating, constipation, IBS, nausea, and pass-out feelings, fatigue-anemia symptoms, etc., and now everything is gone. At first, I was worried about the 50,000 IU pill being too strong, but please trust me, the first 24 hours of the very first pill was the best day of my life in 4 years. It was a good decision to take this pill, and I recommend everyone to go for it. I am not an expert, but there is definitely a very good reason why our doctors prescribe D2 instead of over-the-counter D3 supplements. I am enjoying it and thanking my doctor in my prayers every night."

Vitamin D2 (ergocalciferol) for Vitamin D Deficiency "After years of chronic pain and depression that responded to nothing, I finally asked for a Vitamin D blood test. BINGO. Low normal is 40 - I was a 4. After 8 weeks of once-a-week doses of 50,000 units, and a daily dose of 2000 units, I am feeling better than I have in years! I live in AZ - low D can happen anywhere!"

Vitamin D2 (ergocalciferol) for Vitamin D Deficiency "Leg/foot cramps stopped - hair stopped falling out - joint (knee) pain considerably better - more energy. I had no idea I was deficient since I live in Southern Arizona and am in the sun a LOT - plus I was taking 2,000 IU of a good (Carlson) supplement. I highly recommend this product."

For Vitamin D Deficiency "I am 62, recovering from 2 heart attacks, sepsis from a 4-inch liver abscess, acute diverticulitis, type 2 diabetes, severe arthritis, and moderate to severe stenosis from spinal injuries to my neck and lumbar. I also tend to depression. I teach AP English at a nationally ranked high school. I love my work and don't want to retire, even when I feel bad, even though the workload is intense. When I could no longer keep up then, my PCP drew enough blood to animate Frankenstein's monster and prescribed 50,000 IU of D2. Within 24 hrs of the first dose, I had my best day in many months, then another and another. No side effects (not even migraines that I have suffered since age 14). Who knew vitamin D made so much of a difference?"

Vitamin D2 (ergocalciferol) for Vitamin D Deficiency "I have had major surgery for osteochondritis dissecans when I was a young adult, and recently have begun to experience chronic pain (bad), difficulty bending my knee, and was prescribed 50,000 units once a week for 8 weeks by my PCP, not the orthopedic surgeon. I am shocked my pain has dropped to almost nonexistent, knee bends fine."

For Vitamin D Deficiency "I was feeling sleepy all the time and just didn't want to do anything at all. I went to my doctor and had my blood work done to find out my vitamin D was very low. She put me on ergocalciferol vitamin D. My hair has stopped falling out, I stay on the go now and back to my old self. Thanks for blood work that tells the truth!"

Vitamin D2 (ergocalciferol) for Vitamin D Deficiency "I took Vitamin D2 50,000 IU, and it caused me to have heart palpitations. It also caused anxiety, but was probably because the palpitations were quite concerning. I didn't realize it was the D that was causing them until I forgot to take it one week. I took it for a few months before I realized it. Stopped taking it, and no more palps. Tried taking Vitamin D3 2000 IU daily, and within 3 days of taking it, I had the palpitations again. I then tried 400 IU a day for about 3 weeks, and no palpitations. I am now trying 600 IU and having palpitations again. It is definitely the Vitamin D because when I stop taking it altogether, the palpitations stop completely. I am deficient with a level at 18. Been trying to take these for a few years without success. Maybe building up a tolerance with a low dose will work. I hope."

Vitamin D2 (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 had no idea my symptoms were from a Vitamin D deficiency. It's certainly not a quick fix but after a couple of months on this supplement, my symptoms are vanishing, and my hair and skin are much healthier. I'm thankful to my rheumatologist who suggested the test and medication."

For Vitamin D Deficiency "I have seen a lot of bad reviews for this pill. And I've only just started taking it. I took my first one last night. But so far, I have zero aches and pains in my joints and bones. It had gotten so bad that I couldn't sleep at night or sit or lie down without being in severe pain. I don't feel a ton of energy as some people have stated, but it's only been one day. I haven't had any side effects, and I overall feel much better. I'm looking forward to the next six weeks to finally feel normal again. :)"

Vitamin D2 (ergocalciferol) for Vitamin D Deficiency "Doctor prescribed to take one pill, 10,000 units once a week. I took one pill and was highly allergic to it. I almost died because the doctors didn't know how to treat me. My body temperature was through the roof, hives, swollen muscles, lungs failed, all from one pill. I saw three different doctors. The first doctor gave me a shot. The steroid shot did nothing for me, too low of dosage. The second doctor prescribed prednisone but didn't put me on it long enough. I was having an allergic reaction for a whole month. After two weeks, I finally saw a specialist who was able to treat it, but the heavy medication I was on caused me to have liver damage and other problems."

For Vitamin D Deficiency "At age 26, healthy and fit, I suffered through a hemi-migraine that resulted in the appearance of a stroke. Some symptoms lasted years. I did not have a stroke, just a major migraine that caused all the textbook symptoms. Fast forward, age 32, had another hemi-migraine. After many tests and blood work, I only had 4 abnormals: Copper, Vitamin D, beginning of hardening veins in cerebral, and an ANA positive. How can a healthy person who always had low BP, cholesterol, and none of the underlying factors get hardening of arteries?! The neurologist set me up with D2, 50,000/week and D3, 10,000/daily. No adverse side effects, I don't have as much foggy brain, depleted energy, nor the severe sensitivity to fluorescent lights. I always believed if I ate the right foods, taking supplements was not necessary. It wasn't 24 hours after taking it that I saw a difference, more like a gradual incline. I respect my neurologist for addressing the reason for these migraines, not giving me something to mask it."

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."

For Vitamin D Deficiency "I was put on this medication for extremely low levels of vitamin D. I was put on 50,000 units once a week. About 6 or 7 hours after taking it, I ended up in the ER that night feeling like my throat was closing up and couldn't breathe or swallow. I was also dizzy and confused for many days afterward."

For Vitamin D Deficiency "My doctor prescribed 50,000 i.u. once a week. The first, second, and third week, the headaches were bearable. Today, I thought I would need to call emergency. I never had experienced a headache like the one I suffered 6 hours ago. I am grateful for the changes this medicine has made in my life. My doctor may simply need to adjust the dosage. I only wish that I had been informed of the possible side effects. I am a 75-year-old female."

For Vitamin D Deficiency "Was diagnosed with vitamin D deficiency and osteoporosis. Took this medication for 13 weeks now, have not noticed any side effects or benefits. Only coincidental effect I've noticed is that I had to lower my seizure medicine as I was experiencing moods and mild depression. Will have follow-up blood test soon and will come back and post results. Hope this helps for anyone afraid of taking this medication as I was, due to posted or possible side effects. I have not noticed any negative effects to date."

For Vitamin D Deficiency "I have D deficiency. My doctor prescribed VIT D 50,000 IU D2 (ERGO) caps for me. I took one capsule yesterday afternoon after I got my prescription. I have been having a terrible headache for over a day now. I just realized my headache is caused by the D2 capsule I took. It can be toxic for certain people!!"

For Vitamin D Deficiency "I’ve been taking this at 50,000 IU once weekly for a little over a year now. My levels are rising slowly. Started at 6 and now I’m at an 18. I expected it to raise them a lot faster, but it’s working, and I have no side effects, so I can’t complain."

For Vitamin D Deficiency "After a routine blood test for a physical, it was discovered that I had a vitamin D deficiency. My Dr. recommended ergocalciferol 50,000 IU capsules once a week for 12 weeks. Around 6 hours after I took that first dose, I woke up confused and weak, it was the worst day of my life. My personality changed completely, I thought I was going crazy. I cried, I was screaming, I couldn't even stand up from my bed. At some point, I passed out for a short period, and when I finally opened my eyes, everything was spinning. My husband rushed me to the hospital, and after a few tests and a CT scan, it was determined that I had a really bad adverse reaction to the vitamin D. They gave me fluids, and I guess that's what helped me to recover."

For Vitamin D Deficiency "I'm hoping for the best. I have been terribly sick for years and just took my first dose of weekly D2, 50,000 units. Lately, my sickness was getting unbearable. Felt sick and weak constantly. My hair is falling out, my skin is awful. I had no idea I had low vitamin D until my PCP did lab work. Fingers crossed I get better."

For Vitamin D Deficiency "I was prescribed 50,000 once weekly for 12 weeks for a severe D deficiency. I had been having headaches, but about 2 weeks into it, I started having SEVERE brain shakes/tremors that were constant. Since I had been having some neuro trouble already, it did not occur to me that the ergocalciferol would be the cause. It was not until I created a timeline (11 weeks in) that I realized the D3 might be the culprit. I stopped taking it, and within 7-8 days, was free from these tremors. I was then put on 5000 units a day, and after about three days, the brain shakes/tremors started again. I stopped taking the D3, and the tremors stopped again. Now I am left with trying to get my D up without D2 or D3 supplements. Arg!"

For Vitamin D Deficiency "Was prescribed 50,000 IU of Drisdol once a week for 12 weeks. I was reluctant to take it since OTC Vitamin D3 triggers migraines. My doctor assured me that, since Drisdol was Vitamin D2 NOT D3, it wouldn't cause headaches. Boy, was he WRONG. Within 24 hours after taking the first capsule, I had a severe migraine that none of my usual meds even made a dent in. I ended up suffering in bed for three days. Oh, did I mention the horrible knee pain that came along with the migraine? I guess I was lucky that I had to stay in bed since my legs hurt too bad to walk. Needless to say, I stopped the Drisdol. I'm sure my doctor won't be happy with my decision, but if he had the reaction to Drisdol that I had, I'm sure he would stop taking it too."

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."

Vitamin D2 (ergocalciferol) for Vitamin D Deficiency "HORRIBLE experience. Like other people, I found out I have a vitamin D deficiency and was told to take 15 mcg (600 IU) a day. I took my first pill without thinking of anything, and within two hours, I was having horrible anxiety, panic attacks, heart palpitations, and a high heart rate. The high heart rate triggered anxiety and panic attacks. I quickly drove myself to the hospital where they told me it was not related. After realizing others have experienced it, I’m not sure I fully trust medical providers at this point. I will not be taking that again, and I hope these symptoms subside."
