Perfect for professionals seeking a scientifically backed supplement to enhance overall vitality and resilience. ## Description Cysteine is an amino acid essential for the body to produce proteins, which perform numerous life-sustaining functions. It occurs naturally in foods and is also synthesized in the body when sufficient methionine is available. The body uses cysteine to create glutathione, an antioxidant that helps protect cells from oxidative damage caused by free radicals. Cysteine is a key component of keratin, the primary protein in skin, nails, and hair, supporting their structure and promoting skin elasticity. Additionally, cysteine plays a role in supporting respiratory health by helping to break down proteins in mucus. It also contributes to detoxification processes in the body, supporting overall wellness. These statements have not been evaluated by the Food and Drug Administration.
