Energy balance

Increased mitochondrial reactive oxygen species (ROS) production and oxidative damage contribute to age-related mitochondrial dysfunction and muscle loss, but this can be mitigated by upregulating antioxidant defenses through exercise and caloric restriction.

Oxidative stress damages mitochondria and contributes to muscle loss. Instead of relying solely on antioxidant supplements, focus on lifestyle strategies like exercise and caloric restriction. These approaches upregulate your body's natural antioxidant defenses, improving mitochondrial function and reducing oxidative damage.

GoodSupportsHIGH confidence
Mitochondria are the major producers of reactive oxygen species, which damage DNA, proteins, and lipids if not rapidly quenched... These changes may in turn alter mitochondrial dynamics... and mitochondrially induced apoptosis, which may also lead to net muscle fiber loss and age-related sarcopenia. Fortunately, strategies such as exercise and caloric restriction that reduce oxidative damage also improve mitochondrial function.

Why this rating

Supported by multiple studies showing increased ROS and oxidative damage in aged muscle, and animal models where antioxidant targeting improved function.
