Where is magnesium absorbed?

Based on literature review, magnesium is absorbed mostly in the small intestine and to some extent in the large intestine [ 3 ]. There are two pathways, namely, paracellular and transcellular, for magnesium absorption. Paracellular absorption is the passive transport which is responsible for 80–90% of uptake [ 4 ].

What factors affect magnesium absorption?

The process by which the body absorbs magnesium is complex and impacted by various internal and external factors. External factors affecting our body’s ability to absorb magnesium include food and medication intake. Do Certain Foods Affect Magnesium Absorption?

Does magnesium absorb water?

The most bioavailable (aka absorbable) forms of magnesium are bound to other compounds. As renowned integrative physician Robert Rountree, M.D., explains, "Magnesium absorbs water. So when you take straight-up magnesium, like magnesium oxide, it forms these clusters of water, and that basically hurries things along in the gut."

How much magnesium is absorbed in the gut?

Of the total dietary magnesium consumed, only about 24–76% is absorbed in the gut and the rest is eliminated in the faeces [ 46 ]. It is noteworthy that intestinal absorption is not directly proportional to magnesium intake but is dependent mainly on magnesium status.
