Peptides for longevity and energy
NAD+ and glutathione are the two most-studied compounds in longevity and cellular-health research, tied to mitochondrial energy and antioxidant defense. Here is what the research shows.
What the research shows
NAD+ is a coenzyme present in every cell and essential to mitochondrial energy production; its levels decline with age, making it a central target in longevity science. Glutathione is the primary intracellular antioxidant in the body, studied for neutralizing free radicals and supporting detox pathways.
Energy and defense
NAD+ research focuses on cellular energy and aging, while glutathione research focuses on oxidative-stress defense. The two are often studied as complementary parts of a cellular-health protocol.
