The Claim

Magnesium supplementation at a dosage of 360 mg elemental magnesium per day for 16 weeks has no significant effect on HbA1c, insulin resistance (HOMA-IR), or systemic inflammation (hs-CRP, IL-6) in older adults with pre-diabetes and hypomagnesemia.

In plain English

Taking 360 mg of elemental magnesium daily for 16 weeks does not change blood sugar levels, insulin resistance, or markers of systemic inflammation in older adults with pre-diabetes and low magnesium levels.

See the scientific wording

Magnesium supplementation does not significantly improve HbA1c, insulin resistance (HOMA-IR), or systemic inflammation (hs-CRP, IL-6) in older adults with pre-diabetes and hypomagnesemia after 16 weeks of treatment with 360 mg elemental magnesium per day.

Why this might work

When magnesium levels rise in the blood, cells take in more magnesium, which helps insulin receptors work better and move glucose into muscle and fat cells. This lowers fasting blood sugar. But in older adults with pre-diabetes and low magnesium, this improvement does not extend to long-term blood sugar control, insulin resistance, or inflammation markers because the underlying metabolic damage in these tissues prevents the signal from fully translating into lasting benefits.

  1. Study: Oral magnesium supplementation improves glycemic control in older Chinese adults with pre-diabetes and hypomagnesemia: a randomized controlled trial

    This study gave older adults with low magnesium and pre-diabetes 360 mg of magnesium daily for 4 months and found it didn’t lower their HbA1c, insulin resistance, or inflammation markers—even though it fixed their low magnesium levels. So, the claim that magnesium doesn’t help these specific blood sugar and inflammation measures is supported.
