The Claim
In aged mice, a two-month magnesium-deficient diet leads to accelerated intestinal aging, characterized by colon shortening, increased inflammation and immune cell infiltration, elevated senescence markers, and exacerbated experimental colitis, whereas magnesium supplementation mitigates these effects, suggesting that adequate magnesium intake protects against age-related gut dysfunction and inflammatory bowel disease.
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.
Scientists fed old mice food without enough magnesium. This made their guts age faster and get more damaged, but giving them magnesium helped their guts heal. So eating enough magnesium can help keep your gut healthy as you get older.
See the scientific wording
In a controlled animal study, feeding aged mice a magnesium-deficient diet for two months led to accelerated intestinal aging, characterized by colon shortening, increased inflammation and immune cell infiltration, and elevated senescence markers, whereas young mice on the same diet showed no such changes. Additionally, magnesium deficiency worsened the severity of experimentally induced colitis in mice, while magnesium supplementation alleviated these effects. These findings suggest that the aging gut is especially sensitive to magnesium deficiency, and adequate magnesium intake may protect against age-related gut dysfunction and inflammatory bowel disease.
As animals get older, their gut cells have fewer doorways (magnesium transporters) to bring in magnesium. With less magnesium inside, the cells can't make the right chemical tags on the proteins that glue the gut lining together. These proteins become weak, so the gut lining gets leaky. This allows immune cells to sneak in and cause swelling and damage, which speeds up gut aging and makes the gut more likely to get hurt by things like colitis. Eating enough magnesium keeps the transporters working and the gut lining strong, protecting against these problems.

1 studyStudy: Magnesium Deficiency Accelerates Gut Aging and Increases Susceptibility to Colitis
Old mice that don't get enough magnesium have more gut problems, and eating more magnesium seems to protect against gut issues in people too.
