S-Adenosyl methionine (SAMe) is a naturally occurring compound found in nearly every cell of the body, where it plays a central role in methylation reactions, neurotransmitter synthesis, and cartilage maintenance. Research suggests that SAMe supplementation may offer meaningful support for mood, with multiple clinical studies indicating benefits comparable to certain conventional approaches for mild to moderate depression. Studies also point to potential benefits for joint comfort, particularly in osteoarthritis, where SAMe appears to support cartilage health and help manage discomfort over time. Additionally, research has explored its role in supporting liver function, especially in cases involving impaired bile flow, as well as preliminary evidence for fibromyalgia-related symptoms. SAMe is most commonly available in enteric-coated tablet form to protect its stability through digestion.
