A member asked:
Is cysteine an essential chemical? where do we get this amino acid from food? please advise!
A doctor has provided 1 answer
Cysteine: Cysteine is a semi essential amino acid. Our body can synthesize it if sufficient methionine is consumed. It is contained in high protein foods, such as poultry, eggs, dairy, pork, and grains too. It is a precursor to glutathione in our livers, an essential antioxidant. It also participates in protein synthesis in tissue repair. It is a crucial amino acid from these two perspectives.
