164: How to increase red blood cell magnesium content?

Masterjohn Q&A Files Episode 164


Question: How to increase red blood cell magnesium content?

Well, the first thing you want to do is look at your serum levels. And if your serum levels are low, you want to look at your urinary levels. And if your serum levels are not low or especially, if your serum are high, then you want to focus on promoting magnesium absorbed into the cell.

If your serum levels are low, then you probably don't want to focus on that, you want to focus on magnesium intake or retention or absorption. If you're focusing on getting it into the cells, you're looking at insulin sensitivity, insulin stimulation, vitamin B6 and salt. For urinary loss, you're looking at anything that causes too much urinary output, stress. And if you still can't find the answer, you might want to start looking at certain genetic polymorphisms.
