Vitamin D and Magnesium
by: Nora

I have visited your site many times in recent weeks. I only wish I had found it about seven years ago. I perhaps could have prevented all those years of suffering.

I have a doctor, well a few doctors, four to be exact that kept putting me on high doses of Vitamin D2, 50000 IU weekly, I kept telling them how I was not dealing well with it and they ignored me, repeatedly.

This last time, I just could not take anymore. I was in such pain and the vitamin d seemed to be making all my symptoms more pronounced. Symptoms like difficulty swallowing, nausea, bone pain, muscle aches, all over body twitches, severe depression, insomnia some times, always exhausted, sometimes sleeping for a very long time, but never rested and spasms. The list goes on and on. I told my doctor this and she just ignored me and had the nurse call me later when she got my vitamin d results back and they were no better and had gone down a point or so even, 14 I believe.

I got on the internet and researched and researched, and came to your site, at last!!! Finally information that made sense!!! I could barely move at this point, it was as if my body were not my own, or at least I did not want it to be mine.

I got up early and went to the store and bought some magnesium and vitamin D3 supplements. I came home and started taking them right away. I then tried to sleep, I woke up a few hours later and still ached all over. Oddly enough, I started feeling better quite quickly though. Before I knew it my pain was gone, the twitches were gone, heart palpitations almost gone, and chest pains almost gone.

It has only been a month or so but most of my symptoms are gone or lessened greatly. I feel like my body has a long way to go in restoring itself, but I have something I have not had for many years, HOPE!!!


I wish I could find a doctor that would help me to evaluate my overall health and help me to get on the right supplements all the way around. The chances for that seem to be slim to none, since my doctor didn't even know that I needed magnesium along side of the vitamin d. I am just so angry, and sad that I suffered for so long and was treated like a hypochondriac by my doctors.

I can't tell you what you 'need' to do

Hi Wallace,

I cannot tell you what you 'need' to do. That is not my place. I can only give you information. And the first bit of information that you should know is that 3000 IU's of vitamin d is PITIFULLY insignificant and it will NOT correct your vitamin d deficiency. Please read my page on Vitamin D Therapy and follow the instructions there. Your doctor is NOT in any way following the correct 'standard of care' to treat vitamin d deficiency and you are going to get retested in 3 to 6 months only to find that your vitamin d level is unchanged and you and your doctor are both going to panic to try to figure out what is 'wrong' with you. Well, it's going to be simply that you are taking less than half the dosage that you should be.

Then also please read my page on Vitamin D and Constipation to see what I've said about this subject 1000 times before....
