Magnesium & Insulin Resistance

Magnesium is a mineral involved in over 300 metabolic processes in the body. Every cell in our body depends on magnesium to function and magnesium plays a key role in keeping these cells functioning optimally.
Despite the importance of magnesium, most Americans do not obtain enough magnesium from dietary sources. A study published in the Journal of the American Medical Association found that:
“. . .a significant number of patients with serum magnesium abnormalities are clinically unrecognized and demonstrate the efficacy of routine serum magnesium measurements.”
New research has revealed that insulin receptors are another of the body’s functions that rely on magnesium to function and respond to insulin properly. Additionally, high levels on insulin can increase the amount of magnesium excreted from the kidneys. This results in a vicious cycle in which lack of magnesium causes insulin resistance and excessive insulin reduces levels of magnesium.
A 2015 study published in the journal Diabetes Metabolismevaluated the efficacy of magnesium supplementation on individuals with prediabetes and low magnesium:
“At the end of the trial, significant changes compared to placebo were seen. The researchers found an 11.6% reduction in fasting glucose, a 8.8% decrease in post-meal glucose, a 30.5% decrease in insulin resistance scores, and a 26.7% decrease in triglycerides.”
