Magnesium supplementation is associated with high participant satisfaction and perceived improvements in sleep quality in adults with type 2 diabetes

In a cross-sectional survey of 132 participants from a randomized, double-blind clinical trial on magnesium supplementation in type 2 diabetes, 87.88% would recommend participation and over half reported symptom improvements, including in sleep quality. Satisfaction scores were consistently positive, with high internal consistency (Cronbach's alpha=0.93) and strong construct validity.
