Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This study investigated the effects of magnesium oxide supplementation on glycemic control in older adults with pre-diabetes and hypomagnesemia, finding a significant reduction in fasting plasma glucose.
Clinical relevance
Improving glycemic control in older adults with pre-diabetes is crucial to prevent the progression to type 2 diabetes. This study suggests that magnesium supplementation could be a simple and effective strategy to lower fasting plasma glucose, potentially aiding in diabetes prevention efforts.
Keep in mind
The study did not find significant changes in several key glycemic markers. The sample size and characteristics may limit generalizability. The effects on long-term diabetes outcomes remain unclear.

Efectos Principales
Magnesium supplementation significantly reduced fasting plasma glucose by -0.497 mmol/L (p=0.003).
No significant differences were observed for insulin levels.
The reduction in insulin resistance favored the magnesium group but was not statistically significant.
