Hi hopeful
I have had a huge struggle keeping my magnesium levels up due to my tacrolimus intake. I had to go to the hospital every week to get IV magnesium.
The hospital recomended some magnesiumtablets containing magnesium oxide, which I ate for a couple of months. However, they didn't help me at all, and I started a more scientific approach to my problems.
After searching pubmed.org for a couple of hours, I found out that magnesium oxide has a bioavailability of only 4%!!
A much better complex is magnesium citrate. I don't recall the bioavailability, but it was many times better than oxide.
So I found some magnesium citrate on the internet (couldn't find antydning in my country), and ordered it home for testing. And amazingly it works very well! I now have a magnesium level in my blood that is within normal range, even though i take the same amount of tacrolimus as usual.
So I would recomend to try and get some magnesium citrate. And if you do, please let us know if it works for you.
Best of luck
