The Claim

Magnesium repletion after a period of magnesium deficiency reverses diastolic cardiomyopathy in mice, restoring normal cardiac relaxation, cellular ATP levels, mitochondrial function, and reducing S-glutathionylation of cardiac myosin binding protein C (cMyBPC).

In plain English

In mice, not getting enough magnesium causes a heart problem where the heart can't relax properly. Giving them magnesium again completely fixes this: their hearts relax normally, cells get their energy back, and a specific heart protein is restored to its healthy state.

In mice, magnesium repletion after a period of deficiency reverses the diastolic cardiomyopathy, restoring normal cardiac relaxation, cellular ATP levels, mitochondrial function, and reducing S-glutathionylation of cMyBPC.

Why this might work

When the body doesn't get enough magnesium, the heart muscle cells run low on this important mineral. Without enough magnesium, the tiny powerhouses inside cells (called mitochondria) stop working properly and make harmful oxygen molecules that can damage the heart protein that helps the heart relax. This damage makes the heart stiff and unable to relax well, leading to heart problems. When magnesium is given back, the powerhouses recover, the damage is cleaned up, and the heart returns to normal.

    Mice that lacked magnesium had heart problems, but giving them magnesium again fixed everything, so the claim is right.
