The Claim

Magnesium oxide supplementation at a dose of 360 mg elemental magnesium per day for 16 weeks is well-tolerated in older adults with pre-diabetes and hypomagnesemia, with no gastrointestinal adverse events reported.

Description
1 study reviewed
In plain English

In older adults with pre-diabetes and low magnesium levels, taking 360 mg of elemental magnesium from magnesium oxide daily for 16 weeks did not cause any gastrointestinal side effects.

See the scientific wording

Magnesium oxide (360 mg elemental magnesium daily) is well-tolerated in older adults with pre-diabetes and hypomagnesemia, with no reported gastrointestinal adverse events over 16 weeks despite its low bioavailability.

Why this might work

Magnesium enters the bloodstream from the gut, moves into muscle and fat cells, and helps activate the insulin receptor so it can signal the cell to pull glucose out of the blood. This lowers blood sugar levels without causing stomach problems.

  1. Study: Oral magnesium supplementation improves glycemic control in older Chinese adults with pre-diabetes and hypomagnesemia: a randomized controlled trial

    This study gave older adults with low magnesium and pre-diabetes 360 mg of magnesium oxide every day for 4 months, and no one had stomach problems like diarrhea or nausea. So yes, it seems safe for them to take.
