The Claim
In obese adults, serum magnesium levels below 1.8 mg/dL are independently associated with higher HOMA-IR scores after adjustment for BMI and age.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Obese adults with low blood magnesium levels have higher markers of insulin resistance, even when accounting for body weight and age.
See the scientific wording
In obese adults, serum magnesium levels below 1.8 mg/dL are independently associated with higher HOMA-IR scores, even after adjusting for BMI and age, suggesting magnesium status may contribute to insulin resistance beyond general adiposity.
Low magnesium in the blood reduces the ability of insulin receptors to activate properly, which stops cells from taking in sugar. At the same time, low magnesium increases inflammation, which further blocks insulin signaling. Together, this causes sugar to build up in the blood and the body to produce more insulin to compensate.
What the research says
1 studyStudy: Magnesium Deficiency and Its Impact on the Development of Insulin Resistance in Obese Individuals
In obese people, those with lower magnesium in their blood tended to have worse insulin resistance, even if they had the same weight or age as others — meaning magnesium might play its own role in how the body handles sugar.
