Dimethylglycine is a naturally occurring amino acid derivative that plays a role in various metabolic processes in the body. It is formed from the breakdown of choline, a nutrient found in foods like eggs and liver. Dimethylglycine is involved in the synthesis of creatine and neurotransmitters, which are essential for energy production and communication between nerve cells. This compound is often used as a dietary supplement, with claims that it may enhance athletic performance, improve mental clarity, and support overall health. However, scientific evidence supporting these benefits is limited, and more research is needed to fully understand its effects on human health.
