L-Cysteine

Cysteine

Antioxidant and detoxification support

L-cysteine is a sulfur-containing amino acid that plays an important role in cellular metabolism and antioxidant defense. It is a key precursor for the synthesis of glutathione, one of the body’s most important intracellular antioxidants.

Glutathione participates in biochemical pathways involved in protecting cells from oxidative stress and supporting normal detoxification processes. Because the liver plays a central role in these metabolic pathways, nutrients involved in glutathione synthesis are often included in nutritional strategies aimed at supporting liver function and metabolic balance.

In animals exposed to environmental stressors, dietary changes, or recovery from illness, maintaining adequate antioxidant capacity can help support normal physiological resilience and cellular health.
