The Claim

In mice, magnesium deficiency causes oxidative modification of cardiac myosin-binding protein C (cMyBPC) through S-glutathionylation, a change associated with impaired cardiac relaxation.

Cause and effect
1 study reviewed
In plain English

Mice that don't get enough magnesium have a heart muscle protein that gets chemically damaged, and this damage is linked to the heart not relaxing well.

See the scientific wording

Magnesium deficiency in mice causes oxidative modification of cardiac myosin-binding protein C (cMyBPC) via S-glutathionylation, which is associated with impaired cardiac relaxation.

Why this might work

When mice don't get enough magnesium, their heart cells lose this important mineral. Without enough magnesium, the energy factories (mitochondria) inside heart cells start producing harmful molecules called free radicals. These free radicals attach a chemical tag (which is like a sticky note) to a specific heart protein called cMyBPC. This sticky tag changes the protein's shape, making the heart muscle stiff and unable to relax properly, so the heart has trouble filling with blood between beats.

What the research says

1 study
  1. Study: Magnesium Deficiency Causes a Reversible, Metabolic, Diastolic Cardiomyopathy

    The study showed that when mice were given a diet low in magnesium, a specific heart protein got damaged and the heart became stiffer, but when magnesium was added back, these problems went away.
