I have type 2 diabetes uncontrolled. i also have metastatic breast cancer since 2015. i have some damage to my kidneys from chemo. i can't keep magnesium in me. i get iv mag rider every 3 weeks but it's not enough. ? can i do? what is recom product?

You lost magnesium in the urine because of polyuria due to uncontrolled DM + chemotherapy induced kidney disease (tubulopathy). I wonder how much magnesium you take a day by mouth but you still can not make up for urine loss. Intermittent IV mag rider q 3 weeks is not effective because most of the transfused magnesium will be lost in the urine right away.
