Episode 22 – The Dark Side of Electrolytes (Part 5: Magnesium)

 

Magnesium is a co-factor in more than 300 enzyme systems that are responsible for biochemical reactions in the body. This includes protein synthesis, muscle/nerve function, blood glucose control, and blood pressure regulation. In this podcast episode, we continue our popular electrolyte series by discussing this important electrolyte. As usual, we touch on hyper and hypo states, supplementation, and other reasons to administer magnesium sulfate aside from hypomagnesemia replacement.

  1. Great article ! Mag is probably the most overlooked electrolyte. I really enjoyed this series, electrolytes are typically the second thing i check on all transfers (behind an ABG/VBG). iCA and K are the big ones i focus on but mag and sodium have alot of very specific uses that we need to constantly remind ourselves about. Keep up the good work.
