Cysteine is an amino acid that is naturally found within our bodies. You get cysteine in your system by eating protein-rich foods like meat, fish and soybeans. Cysteine builds a strong antioxidant known as glutathione within the body, which helps it to fight infection. Our bodies make cysteine from methionine and serine amino acids. If these amino acids are only available in small supplies, a cysteine supplement may be required. Cysteine is very effective at managing diabetes, easing virus symptoms like flu and treating inflammation.
