Magnesium can be useful for blood sugar control, especially in individuals with insulin resistance or type 2 diabetes. Observational studies and some randomized trials suggest that magnesium supplementation improves insulin sensitivity and reduces fasting glucose levels. However, the effect is modest and most pronounced in people with low magnesium status. It is not a substitute for standard diabetes treatment or lifestyle measures. High doses may cause diarrhea and gastrointestinal discomfort. For healthy individuals without deficiency, the benefit is unclear. Therefore, while magnesium has a supportive role, it should be used cautiously and ideally after checking magnesium levels. Evidence level: human-moderate.
