Hi all. My doctor did some blood rutine blood tests on December 2015 (4 months ago) and the only bad thing that came back on the results was Vit D @ 32 (cant remember the units). Since then, he prescribed 2000ui daily intake of Vit D3. I have since then taken Vit D3 daily for about 2 months, then I started being lazy or forgetting about it so sometimes I would take two pills (4000ui)if I missed taking them the day before. Fast forward to a week ago, I started taking the fast acting liquid Vit D3 capsules, 2 a day, and I started having what it feels like heart palpitations here and there. Could this be related to my Vit D3 intake at 4000ui instead of 2000ui? Fast acting liquid capsules? It seems as if the symptoms started around the same time I started the fast acting capsules. Any help would be appreciated, thank you!

    My guess is that you may be running yourself out of magnesium when you take the higher amount of Vitamin D. It’s not that you do not need the 4000iu, I think you just need to get a magnesium supplement. If possible do NOT get magnesium oxide. Any other magnesium or magnesium chloride is fine. I would try for a minimum of 200mg but you may need more. There is more information at http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    The Vitamin D “units” can make a big difference. If you are 32ng/ml then the 2000iu a day will probably get you to our recommended “healthy” level of 50ng/ml. If the 32 is being measured as nmol/l that would translate to 13ng/ml. At this level you would need to take 4000iu everyday or our recommended 5000iu everyday to reach a healthy level.
