A study of 68 adults with type 2 diabetes in India found that median blood magnesium levels were lower in participants with higher HbA1c, a marker of average blood sugar over the past two to three months, according to the study. The median magnesium level was about 2.1 mg/dL in the higher HbA1c group compared with 2.3 mg/dL in the better-managed group, the study stated. Five participants in the higher HbA1c group had hypomagnesemia, meaning their blood magnesium levels fell below the normal range, according to the study. The study did not establish whether low magnesium precedes elevated blood sugar or results from it, researchers said. The findings add to a body of research examining the relationship between magnesium status and glycemic control in adults with type 2 diabetes [1].

Study Design and Key Findings

Researchers split the 68 participants into two groups based on HbA1c and compared blood magnesium levels alongside other markers of metabolic health, according to the study. Magnesium levels were lower in participants with higher blood sugar, and low magnesium levels were found only in the higher HbA1c group, the study stated. Lower magnesium levels also were associated with higher triglycerides, suggesting a potential relationship between magnesium status and other markers of metabolic health, according to the study. Within the higher HbA1c group, magnesium was not significantly linked to HbA1c, although researchers observed a trend toward lower magnesium alongside higher HbA1c. The relationship was not statistically significant, the study stated. Medical literature has documented that magnesium status is frequently altered in individuals with type 2 diabetes, and the mineral serves as a critical cofactor in more than 300 enzymatic reactions, many of them involved in glucose metabolism [2].

Previous Research and Biological Context

Past research has linked magnesium to insulin signaling and the movement of glucose into cells, according to the report. Elevated blood sugar may also increase magnesium loss through urine, potentially making it harder to maintain adequate levels, the report stated. Observational research has found that low dietary magnesium intake has been related to the development of type 2 diabetes and metabolic syndrome [3]. Some clinical trials have found that magnesium supplementation may improve fasting blood sugar and HbA1c in people with type 2 diabetes, according to prior research cited in the report. The report stated that getting more magnesium does not directly or immediately translate to better blood sugar, but rather likely supports underlying metabolic processes over time. A separate meta-analysis of 11 clinical trials reported that omega-3 supplementation was associated with lower fasting insulin and improved HOMA-IR scores in people with diabetes, although it reported no significant changes in HbA1c or fasting blood sugar [4].

Magnesium Intake and Sources

Magnesium is an essential mineral, meaning the body cannot produce it on its own and must obtain it daily, according to the report. About 43% of U.S. adults do not get enough magnesium through diet alone, the report stated. A July 2026 report on magnesium deficiency stated that roughly half of U.S. adults consume less than the recommended amount of magnesium [5]. Magnesium-rich foods include pumpkin seeds, chia seeds, leafy greens, and beans, according to the report. A separate report listed magnesium among the essential minerals involved in muscle and nerve function, blood sugar regulation, and bone development, and cited National Institutes of Health recommended daily amounts of 400 to 420 milligrams for adult men and 310 to 320 milligrams for adult women [6]. The report stated that many people do not ingest enough magnesium in their diet and that taking magnesium supplements is reasonable, especially for people more likely than others to have low levels of magnesium [7].

Conclusion

The study adds to existing evidence of an association between magnesium status and blood sugar control in adults with type 2 diabetes. Researchers could not determine whether low magnesium causes elevated blood sugar or whether elevated blood sugar lowers magnesium, according to the study. The report stated that adequate magnesium intake through food and supplements supports overall metabolic health. Type 2 diabetes remains a condition that many individuals have successfully addressed through lifestyle measures including diet and physical activity, according to prior reporting [8].
