The Claim

Melatonin acts as a potent intracellular and mitochondrial antioxidant by directly scavenging reactive oxygen and nitrogen species and upregulating endogenous antioxidant enzymes, thereby maintaining mitochondrial membrane potential, preserving cellular energy production, and protecting cardiomyocytes from oxidative stress-induced damage in cardiovascular pathologies.

How it works
1 study reviewed
In plain English

Melatonin works like a powerful internal cleaner that protects your heart cells from damage caused by stress and aging. It does this by neutralizing harmful molecules, boosting your body's natural defenses, and keeping the energy-producing parts of your cells running smoothly.

See the scientific wording

Melatonin functions as a potent intracellular and mitochondrial antioxidant that directly scavenges reactive oxygen and nitrogen species while upregulating endogenous antioxidant enzymes such as superoxide dismutase and glutathione peroxidase. By maintaining mitochondrial membrane potential and preventing the opening of the mitochondrial permeability transition pore, melatonin preserves cellular energy production and protects cardiomyocytes from oxidative stress-induced damage across multiple cardiovascular pathologies.
