SAM-e (S-Adenosyl Methionine) is a naturally occurring compound found in the body that plays a key role in many metabolic processes, including the synthesis of neurotransmitters and the maintenance of cell membranes. As a supplement, SAM-e is used to help manage symptoms of depression, osteoarthritis, and certain liver disorders. It works by increasing levels of important chemicals in the brain, such as serotonin and dopamine, which can help improve mood and joint health.
