Up to 50% of people with pre-diabetes are deficient in magnesium — and most don't know it. Magnesium is required for insulin receptor function at a molecular level.
What magnesium does for blood sugar:
- Required for over 300 enzymatic reactions, including those that regulate glucose metabolism
- Improves insulin receptor sensitivity directly
- Reduces fasting glucose and HbA1c in people with deficiency (Diabetes Care, 2003)
- Bonus: significantly improves sleep quality and reduces cortisol — both of which further improve glucose control
Recommended form and dose:
- Magnesium glycinate or magnesium malate — best absorbed, gentlest on the gut
- 300–400mg, taken 30–60 minutes before sleep
- Avoid magnesium oxide — poor absorption, mainly laxative effect
⚠️ If you have kidney disease, consult your doctor before supplementing magnesium.
