S-adenosylmethionine (SAM-e)

S-adenosylmethionine (SAM-e) is a naturally occurring compound in the body that has been studied as a supplement to help alleviate depression. SAM-e helps regulate mood by supporting the production of neurotransmitters like serotonin and dopamine. It is often used as an alternative or complementary treatment to antidepressants, though more research is needed to fully understand its effectiveness.
