The Claim

Magnesium supplementation at a dose of 360 mg elemental magnesium daily for 16 weeks increases plasma magnesium concentration by approximately 0.056 mmol/L in older adults with pre-diabetes and hypomagnesemia.

In plain English

Taking 360 mg of elemental magnesium daily for 16 weeks raises plasma magnesium levels by about 0.056 mmol/L in older adults who have pre-diabetes and low magnesium levels.

See the scientific wording

Magnesium supplementation effectively corrects plasma magnesium deficiency in older adults with pre-diabetes and hypomagnesemia, increasing plasma magnesium by approximately 0.056 mmol/L after 16 weeks of 360 mg elemental magnesium daily.

Why this might work

When magnesium is taken by mouth, it enters the bloodstream and raises the level of magnesium in the blood. This extra magnesium moves into muscle and fat cells, where it helps activate the insulin receptor so it can signal the cell to pull glucose out of the blood. More glucose enters the cells, and blood sugar levels drop.

  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 daily for 16 weeks, and their blood magnesium levels went up by exactly the amount claimed — about 0.056 mmol/L. So yes, it works as described.
