The Claim
Oral magnesium supplementation at a dose of 360 mg elemental magnesium per day for 16 weeks significantly reduces fasting plasma glucose by approximately 0.50 mmol/L in older adults with pre-diabetes and confirmed hypomagnesemia, but does not significantly improve HbA1c, insulin resistance, or inflammatory markers.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 360 mg of elemental magnesium daily for 16 weeks lowers fasting blood glucose by about 0.50 mmol/L in older adults with pre-diabetes and low magnesium levels, but does not change HbA1c, insulin resistance, or inflammatory markers.
See the scientific wording
Oral magnesium supplementation (360 mg elemental magnesium per day for 16 weeks) significantly reduces fasting plasma glucose by approximately 0.50 mmol/L in older adults (mean age 68.7 years) with pre-diabetes and confirmed hypomagnesemia, but does not significantly improve HbA1c, insulin resistance, or inflammatory markers.
When magnesium levels in the blood rise, more magnesium enters muscle and fat cells, where it helps activate the insulin receptor. This triggers a chain reaction that moves glucose transporters to the cell surface, allowing more glucose to leave the blood and enter the cells, which lowers fasting blood sugar.
What the research says
1 studyThis study found that taking 360 mg of magnesium daily for 4 months lowered fasting blood sugar by about 0.5 mmol/L in older adults with low magnesium and pre-diabetes, but didn't help their HbA1c, insulin resistance, or inflammation — just like the claim says.
