Serine

Serine is an amino acid and one of the 20 most common natural amino acids on Earth. It is a non-essential amino acid meaning that human cells can produce enough of it for the body's needs, unlike essential amino acids that must be obtained from food. Serine is critical for many biological functions, including biosynthesis of proteins, cellular energy production, and metabolism. It plays a key role in DNA and RNA replication, as well as signal transduction of various hormones and neurotransmitters. Serine is also required for healthy joints, brain and nervous system development, and proper immune system functioning. It is found naturally in dairy, meats, eggs, nuts, legumes, and certain fruits and vegetables. Supplementation of serine may have positive effects in people with depression, schizophrenia, and other mental health conditions.
