Taking a 250 mg NMN supplement every day for a few weeks might boost a key molecule in your blood that helps your cells make energy and slows down some aging effects.
Taking a daily 250 mg NMN supplement for a couple of months might help older men get stronger and move better — like gripping things tighter, walking faster, and standing up from a chair more easily — without changing their body fat or muscle mass.
