The Active Ingredient Is: L-Cysteine

L-Cysteine is a non-essential amino acid that serves as a building block for proteins and a precursor in glutathione synthesis, contributing to cellular protection and metabolic health.

This form is the pure amino acid in supplement form, sourced to support its role in antioxidant pathways and immune function.

What Does L-Cysteine Do?

L-Cysteine helps support antioxidant status by contributing to the body’s glutathione supply, which is involved in protecting cells from oxidative stress. This function aligns with established nutritional guidance on maintaining healthy redox balance and metabolic health, as discussed in research from Dr. García-Fernández at the University.

Overall, L-Cysteine is involved in antioxidant protection and immune support mechanisms that underpin healthy cellular function.
