S-adenosylmethionine (SAM)

S-adenosylmethionine (SAM) is a naturally occurring compound in the body that plays a crucial role in many biological processes. It acts as a donor of methyl groups, which are small molecules used to modify DNA, proteins, and other molecules, influencing their function and activity. SAM is essential for methylation reactions involved in gene regulation, neurotransmitter synthesis, and liver health. It is produced from amino acids and helps support overall cellular function. Due to its importance, SAM supplements are sometimes used to aid mood, liver health, and joint function.
