Vitamin D3 (cholecalciferol) "I struggle badly with Vitamin D supplements. Don't ever let a doctor tell you it's not the supplement! The only thing I do like about it is for me it's almost like a sleeping pill. I pass out very quickly after taking it every time. However, the next day I always feel tense, dizzy, short of breath, headaches, muscle aches, anxiety, stomach pains, constipation, and have acid reflux issues. This ALWAYS goes away when I stop the supplement. I've tried adding magnesium and it doesn't help."

Vitamin D3 (cholecalciferol) "After my wellness checkup and blood analysis, I was told by my MD to start taking Vitamin D3-2000 daily. I took it as recommended for 2 days and I noticed that I was experiencing dizziness, tiredness, and really bad cramps in my hands, feet, and legs. I thought that I was dehydrated and drank more water. The cramps kept getting worse, and I also started having increased palpitations and more dizziness. As the only change I had made in my daily regimen was taking the D3, I decided to stop taking it to see if it might be the cause. Sure enough, these symptoms disappeared. So, why are we being told to take this? Several of my friends and family have been advised to do the same lately. Is it a new 'health' sham?"

Vitamin D3 (cholecalciferol) "I was told by my doctor that I am Vitamin D deficient and should take 5000 IU of vitamin D per day. I began taking the supplement and within 36 hours began having HORRIBLE leg pains and muscle aches. The pain in my legs was so bad I could barely walk. I was also extremely nauseated, so much so that I couldn't eat. I stopped the Vitamin D and in no time the muscle pains and nausea were gone. I now take 1000 IU of Vitamin D per day with no side effects. I know it's less than my doctor wants me to take but that's too bad. Why do doctors insist on such enormous amounts of Vitamin D without considering the side effects??? I would rather be Vitamin D deficient than suffer the side effects of a 'therapeutic' dose of Vitamin D."

Vitamin D3 (cholecalciferol) "So my doc prescribed me 10000 IU for 6 weeks, since I was vitamin D deficient. After 2 weeks of taking these, I noticed terrible heart palpitations and a fast heartbeat. I went to the ER with a heart rate of 172, the scariest day of my life. Vitamin D makes me so drowsy and dizzy. I'm definitely not taking this anymore. It helped me with my levels; now it is 36, but it's making me feel miserable."

Vitamin D3 (cholecalciferol) "I started taking Vitamin D3 years ago due to deficiency. I have taken 2,000iu and 1,000iu's. For years I have suffered debilitating leg and feet cramps at night and horrible restless legs. I have always blamed it on my blood pressure meds, but have finally figured out that any time I stop taking the d3 I have no more leg cramps. Now I will add 2 drops (about 200ii) into water once in a while, but even that mess me feel sick, so no more!! The leg cramps would even go into my thighs and I would not be able to stand up it was so painful. But of course the Dr said it couldn't be that. Then why does it stop when I stop taking the D3!!?? I wish Dr.s would do more research before just throwing prescriptions at us......"

Vitamin D3 (cholecalciferol) "I have been struggling with arthritis-like pain for months. Swollen joints, pain, hard to move around, and muscle weakness. Started taking vitamin D3 and the difference was night and day. Strength is restored, pain is decreasing... I am on the mend. I used to work outside but now in an office all the time, I guess it played a bigger role in my health than I realized."

Vitamin D3 (cholecalciferol) "I was deficient in D3, and was prescribed 5000 iu per day. Six months later, my Vitamin D level is in the normal range, with no side effects. Possibly pure coincidence, but my Cholesterol level has dropped below 200 for the first time in 30 years, with no change in diet, medication, or exercise! The only difference was the D3. I’m a fan."

Vitamin D3 (cholecalciferol) "Had bloodwork done to determine what my vitamin D level was at, resulted in a value of 19. Never in my lifetime have I taken a vitamin D supplement. Even though I was deficient, I was unsure if I wanted to take 1000 IU daily just in case it reacted on me. So I've been taking 500 IU daily for almost a year now. My bloodwork has improved to now having a value of 55. The only reactions I have noticed that could possibly be from the vitamin D are constipation and heart palpitations (feels like body tremors). I've had heart tests done, resulting in everything being okay. I continue to take the vitamin D supplement but only 500 IU daily."

Vitamin D3 (cholecalciferol) "I was sent to a rheumatologist for arthritis pain. He suggested 50k iu vit D3 for 7 days & 50k iu once a week for the next 7 weeks until my next appt. I have hyperparathyroidism which means I produce calcium oxalate kidney stones. I declined his suggestion on the grounds that that much vitamin D3 would increase my blood calcium level dramatically & therefore my stones also. He knew I had stones but said I needed the vit because it was the calcium producing the “bone spurs” that was causing my arthritic pain. What?? So I want to take more calcium?? Have to find another doctor!"

"I was feeling fine until I was diagnosed with vitamin D deficiency (4.6). I took 8000ui of vit D3 once a week for a month. The 1st time I took it after 3 hours I felt sick all of a sudden, with terrible palpitations, extreme dizziness, nausea, confusion. I thought I was dying! My dr said it was impossible vit D caused this, so he told me to keep taking the drug. 2nd week I ended up in the ER but everything was negative and they told me it couldn't be vit D. I took it 4 times, once a week, until I asked my pharmacist about my symptoms and 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 vit D and my health is slowly improving. Now my vit D level is 16 so I guess the drug worked but I would never take it again with all those side effects"

Vitamin D3 (cholecalciferol) "I was told had osteopenia and calcium was low . I looked at taking calcium and found should not take alone . Few years later was told I needed a script for Fosamax ! I said no way has my vitamin D being checked? Sure enough it was low and was told to take 2000 IU which sounds high but it’s a pittance so did look into it and found it’s why along with low B12 often why bone health isn’t good. I had deep bone pain ,could barely lift my arms and found was losing my grip in my 50’s ! I upped my dose to 10,000 IU with k2 100mg and within a week my pain was gone ! Weeks on this and all grip was back as was able to lift arms ! Also had to have injections of B12 as was on low side (275 - range 240-1000) but also have autoimmune disease . Always take D3 not D2 and daily amount is better than once a week dose because you get high troughs and lows and that needs to be taken with fatty foods(good fats ) to be absorbed. I wish they tested more for deficiencies and effect on body:"

Vitamin D3 (cholecalciferol) "I had bloodwork done, and was found to have very low vitamin D levels, 55nmol/L. My nurse practitioner advised me to take 2,000 IU daily. I was already taking 4,000 IU daily, so I upped the dosage to 10,000 IU. I got my results from my latest blood tests, and I am still deficient in vitamin D, 56nmol/L, a whole 7 months later! Clearly, something else must be wrong here. I am a diabetic, and I am also taking Metformin, Lantus and Humalog insulins, as well as a small dose of Metoprolol."

D3 (cholecalciferol) "Having severe bone loss, my MD put me on vitamin D2 at 50,000 units a week. My wife did the research, and found out vitamin D2 is not as well absorbed as vitamin D3. It also must be taken with a calcium supplement. I had been taking the D2 for several years, and then they wanted me to take Prolia as my bone loss was getting worse. Stopping the D2, and starting the D3 at 5,000 iu a day with 600 mg of calcium has helped quite a bit. I would suggest anyone try this before taking something like Prolia, or Forteo for bone loss. If you have osteoporosis, you need the supplements either way. Wife took Forteo everyday for 26 months, and less than 4 years later they now want her to try Prolia too.Check wikipedia for info on this."

D 1000 IU (cholecalciferol) "I had low vitamin D. My doctor put me on 50,000 iu/week. After first dose I have been to the ER twice. Dizzy, lightheaded, real high, anxiety, massive headaches, twitchy, coordination loss, high heart rate, photo and audio oversensitivity, mental confusion, spinning, eye pressure, "pre dreaming" just shutting my eyes. I have to avoid light, sounds, movement. I make myself eat cause nausea and weight loss. Doctors dismiss it but I have read about serotonin and other levels being too high. I regret taking this and currently waiting for my body to be deficient again, just so I can feel ok. First 15 hours bad. Doctor said 2-3 days but its been my 6th day. Read after 15 days vit d is down to 50%. 25% by 30days. I avoid light, any Vid D foods, anything to cause serotonin levels to go up, I was better off in my level mental state. Hope this may help calm you if you are having effects."

"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, no appetite, and 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."

"My vitamin d levels are 15, so my doctor prescribed 50,000 units once per week, after takin it, I felt very strange, within 2 days my heart was pounding out of my chest, I could not sit still, I was literally out of breath, I was so scsred, i called my doctor's office 3 times and explained what was happening, she said that I might have symptoms of a heart attack, I refused and took my when required klonopin, soon I was feeling so much better, Iwas so scared I thought I was going to die! Dangerous stuff when taking very high doses, your body can only absorb so much at a time! I feel for anyone going through this, don't know how I'm going to get my levels up after what happened. god bless. "

"I have fibromayalgia and the Dr suggested I have my bloods checked and they found that I’m pretty low on Vitamin D .. I was put on colcalciferol 2x 800unit caps a day.. initially I was fine but day 4 my stomach started to whine and churn and I was nauseous. On day 5 I was doubled up in pain, stomach cramps, diarrhoea, banging headache, puffy, bloated! I spoke to the Dr who said it’s not a ‘normal response’ .. she then re checked the ‘possible other side effects’ and there they were .. lots of them. I’ve stopped taking the capsules and 3 days later I’m still poorly, less poorly admittedly but maybe these things should be started gradually. Nasty experience that’s still with me but hopefully it’ll continue to ease in the coming days. Dr suggested I let my gut settle then resume once daily but that is not going to happen."

"I have thyroid issues and I am relatively obese. Obesity binds vit D and creates a deficiency. Catch 22 because you need Vit D to lose weight. Blood test confirmed low levels. Starting taking Calciferol oil, 1ml daily. I noticed that my belly fat was disappearing. I feel so much better and no longer battle binge eating disorder. I suspect I was binging because my body was desperately trying to get hold of this hormone. Now I'm levelled out and know that I will be able to finally lose weight."

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"
