Oral magnesium supplementation significantly increases HDL cholesterol levels in patients with Type 2 diabetes.
Taking magnesium (approx. 360 mg/day) for a few months may slightly improve your 'good' cholesterol (HDL) levels. This is a beneficial side effect for heart health, but it should not be the sole reason for supplementation if your primary goal is blood sugar control.
GoodSupportsHIGH confidence
Magnesium supplementation increased on high-density lipoprotein (HDL) cholesterol levels [0.08 mmol/l (95% CI, 0.03 to 0.14); P = 0.01]
Why this rating
Meta-analysis of RCTs, consistent heterogeneity.
