Κυστεΐνη

L-cysteine is an amino acid that comes from protein sources. It's non-essential, which means that your body can make enough L-cysteine on its own or from other nutrients and amino acids. But, if you get a lot of exercise or you're an athlete, you may need extra L-cysteine support to continue to push yourself towards your fitness peak.*L-cysteine is used to make other amino acids in the body like taurine. Because of its role in creating other amino acids, L-cysteine assists with proper nervous system functioning, immune system functioning, vision, metabolism, and muscle development.* For athletes, L-cysteine may help you burn fat, maintain and develop lean muscle mass, and boost endurance.*
