YouTube video (speaker: Aaron Hartman, MD) discussing magnesium supplementation safety, common deficiency, and types of magnesium. Key points: generally safe with functioning kidneys (excess causes diarrhea), magnesium glycinate recommended/popular, and preference for chelated forms over elemental forms like magnesium chloride (noted as Epsom salt).

Questions this video answers

Aaron Hartman, MD.

Diarrhea.

Magnesium glycinate.

Magnesium chloride.

If the kidneys are functioning okay and you take magnesium, if you get too much, you just get diarrhea. So it's a pretty safe thing to take. And the reality is most of us are deficient in it. Then the question is, what kind? Magnesium glycinate, which is one of my favorite kinds, has gotten a lot of popularity recently for lots of reasons. You want a magnesium that's a chelate. So it's just magnesium plus something that's typically versus elemental magnesium, which is like the magnesium chloride, which is what's Epsom salt, and what's in most magnesium that you mine out of the ground.
