hey i have this question. I have done alot of research and been having symptoms for almost 5 years now, it started out with muslce twitching, panic attacks and numbness and has progressed towards bone pain and fatigue especially after eating carbs, its seems like it has to be something magnesium or vitamin d related. i had a magnesium rbc test done which turned out to be at 5.6 (i forgot the unit) but it was according to the lab in range, then i had a vitamin d test done and it was 20 (the range being 30-50, this is in germany btw). now im eating very good, and i notice everytime i eat magnesium rich foods, or try a magnesium supplement i get horrible paraesthisa, tingling in hands, and when i supplement with vitamin d i get anxiety and cramps, i dont know what to do, i just want to feel normal again, what should my procedure be im willing to do anything at this point. thanks in advance Raul
In Germany Vitamin D is measured as nmol/l. Here in the US it is measured as ng/ml. So your 20nmol/l equals 8ng/ml. Anything below 10ng/ml (25nmol/l) and you are now into Osteomalacia (adult rickets)…

Hi there, I have some questions about the accuracy of a recent 25(OH)D that I am hoping someone can help me out with. I just received my lab results for a 25(OH)D test, and it indicates that my serum concentration is 39 ng/ml. I am highly convinced that it should be lower than this, as I have been experiencing certain symptoms for years that I strongly believe are related to a vitamin D deficiency. Granted, I realize 39 ng/ml is still considered somewhat low by Vitamin D Council standards, but it is nonetheless higher than I was expecting it to be. Because I took high dose (~10,000 IU) vitamin D supplements daily for two days prior to the test, I am wondering if this can affect the test outcome. To be clear, I took ~10,000 IU for two days, then took one day off from any vitamin D supplementation, then the next day I was tested. That was yesterday and I just received my test results today (which, as a side note, seems awfully fast…). Does anyone know how quickly a high dose of vitamin D can affect serum concentration, especially as it relates to the 25(OH)D lab test? From everything I've read about this subject, it sounds like it can take *months* for serum levels to increase in response to supplementation, and so I am leaning towards believing that these supplements likely did not affect my lab results in any significant way. But I just want to be sure nonetheless. Thanks so much for taking the time to read this, and thanks in advance for any feedback on my question!
Thank you so much for the response! I did not see that someone else recently posted a similar question, and so I do apologize for the repetition. I am new to using this website and so am not yet too …

I've began to supplement Vitamin d3&k2 combo. D3:3000IE / K2: 45ug. I felt great the first month, my sleep decreased like 2 hours in total by first day and i still felt energized, it further decreased 2 hours after a month and i felt tired, got insomnia for a while so i started use even more magnesium. 1600mg of magnesium citrate&lysin chelate= 486mg elemental, wasn't enough. So i used chloride magnesium and that saved my insomnia so i can fall asleep, that gives probably atleast 2000 elemental with my rub, an ounce gives 3262mg elemental magnesium!. I still have problems sleeping a whole night. I go to bed at 9 and waking up at 3 and are tired, thirsty and having a headache usually. I thought to myself that i got hypercalcemia due to my symptoms. I did use alot of calcium as supplement because i couldn't fall asleep without it either, so i guess my whole mineral supplies are unbalanced to say the least. I did however had no issues with supplements before i introduced vitamin d3 to my diet. Am i sensitive to the type of vitamin d3 in my supplement? Are there different vitamin d3 sources? Should i stick to a lower dose?
I do not know if you will come back to read this. If you figure this all out at some point, I would appreciate if you came back and told me what happened. For example if you use a lower amount of Vit…
