Why Your Muscles Need This Enzyme to Reap the Benefits of Exercise
Graded Moderate — knockout study in aged mice with human muscle samples confirming the NOX4 decline, though the functional effects and rescue were shown only in animals.
This study hints that sulforaphane from broccoli may support muscle's exercise-like defenses, but it was tested in mice.
In mice and humans, a muscle enzyme called NOX4 drops as we age. This loss weakens muscles and dials down the body's natural defense system that exercise normally switches on. In mice, deleting NOX4 sped up frailty, fat gain, inflammation, and insulin resistance. Sulforaphane, the compound in broccoli sprouts, helped restore those protective responses.
