What this trial studies

This study investigates the effects of oral magnesium supplementation on patients with Type 2 Diabetes Mellitus (T2DM) who have low serum ionized magnesium levels. The hypothesis is that magnesium supplementation, guided by serum ionized magnesium levels, may improve diabetes control and overall disease outcomes. Unlike previous trials that focused on healthy individuals, this study specifically targets T2DM patients and aims to establish a correlation between magnesium levels and diabetes management. Participants will receive magnesium oxide tablets at a dosage of 500 mg.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with Type 2 Diabetes who have an HbA1c level of 7% or higher and are being treated with oral hypoglycemic agents.

Not a fit: Patients with an HbA1c below 7%, those with end-stage renal disease, or those on certain contraindicated medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved diabetes management and better health outcomes for patients with Type 2 Diabetes.

How similar studies have performed: While previous studies have explored magnesium supplementation, this specific approach targeting T2DM patients based on serum ionized magnesium levels is novel and has not been extensively tested.
