We're really into magnesium here at Wild.
Fortunately for us, so are researchers!
There are thousands of studies on the benefits of magnesium, with more coming out each year.
A recent controlled study examining magnesium and insulin sensitivity in Type 2 Diabetic subjects: "Oral Magnesium Supplementation Improves Insulin Sensitivity and Metabolic Control in Type 2 Diabetic Subjects."
Summary of Abstract
The study aimed to investigate the effects of oral magnesium supplementation on insulin sensitivity and metabolic control in subjects with Type 2 diabetes. Sixty-three participants were involved, all of whom had decreased intracellular magnesium levels. They were divided into two groups, one receiving oral magnesium supplementation and the other a placebo for 16 weeks.
- Participants: 63 subjects with Type 2 diabetes
- Design: Double-blind, randomized, placebo-controlled trial
- Duration: 16 weeks
- Intervention: One group received 2.5g of oral magnesium chloride (providing 300 mg of elemental magnesium) daily, while the other group received a placebo.
- Parameters Measured: Intracellular magnesium levels, fasting blood glucose, HbA1c levels, insulin sensitivity, and other blood markers were assessed before and after the intervention.
Researchers' Summary of Findings
The group that received the magnesium supplementation showed a significant increase in intracellular magnesium levels. This group also experienced improved insulin sensitivity and metabolic control, evidenced by reduced fasting glucose and HbA1c levels. The placebo group did not experience any of these improvements.

This study suggests that oral magnesium supplementation could improve insulin sensitivity and metabolic control in Type 2 diabetic subjects with low intracellular magnesium levels.
