I was just taken off calcium and put on vitamin D 5000 I.U. a day. My doctor did this the same day he received my bone density scan. I have been on calcium for years. I also took Prolia last year. My doctor told me my bones were strong enough and to not take Prolia at this time. I am very confused over the amount of vitamin D3 he has asked me to take.

My D3 level was tested through a blood test and is only 9 though for the past 2 years I have taken 5.000 IU/day. I have celiac disease and understand that some people with that disease cannot absorb fat, making it difficult to get enough of that supplement. I am a Caucasian living in the tropics for many years and have had several bouts of basal cell carcinoma, so I avoid the sun as much as possible. Now trying with 10.000 IU/day for 2 weeks, and will be tested again after 1 month.

My vitamin D level is half of the normal, total vitamin D is 25.5 nmol/L. I have to take D3 Vitamin 50,000 IU for my vitamin D deficiency.

I have had vitamin D deficiency for years. I have an injection of vitamin D once a year and within days I am full of energy and feel well for a year.

I was diagnosed with relapse/remitting multiple sclerosis. I take 6,000 units of D3 daily. My vitamin D levels have always been low. I had rickets at 18 months. I drank a gallon of milk weekly and put cheese on everything I could get away with. Recently, I had gallbladder problems and was not able to have cheese for 2 years. Now, with the 6,000 units of D3 daily, I am not as depressed and can have cheese, but not milk. I am highly allergic to antibiotics and milk has traces that make me violently ill.

I take vitamin D3 1000 IU twice a day.

My lab levels of vitamin D came back very low so my doctor prescribed vitamin D3 10,000 IU. I just started taking it.

I went to the doctor for leg pain and muscle aches that just wouldn't go away. She ran tests and discovered I had a vitamin D deficiency. I am now on 50,000 IU vitamin D a week for 12 weeks. I am now on my 3rd week and feel no relief at all. I thought I would notice some difference. Maybe I'm expecting too much too soon?

I have been taken 50,000mg vitD for 8 months now my count still hasn't went up....

I started experiencing dizziness, fainting, bone pain, extreme exhaustion, weight loss, brain fog, and rapid heart rate about three months ago. My vitamin D deficiency was an incidental finding, as I was thinking I was either diabetic or had thyroid problems. It turns out my salvation may lie in the bottom of a vitamin pill bottle. We still have not ruled out the possibility of Paget's disease, but time will tell.

My doctor put me on 50,000 IU a week for eight weeks.
