L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine (from which L-cysteine can be produced in the body by a multi-step process). Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine. Cysteine also helps synthesize glutathione, the body’s most important intracellular antioxidant and a vital detoxifier.

N-acetyl-L-cysteine (NAC) is the acetylated form of L-cysteine that has been used to break up pulmonary and bronchial mucous. It is very efficiently absorbed and has been shown to protect cells directly and support the immune system. N-Acetyl-L-Cysteine (NAC) is an antioxidant and a free radical-scavenging agent that increases intracellular glutathione at the cellular level. N-Acetyl-L-Cysteine (NAC) can act as a precursor for glutathione synthesis as well as a stimulator of the cytosolic enzymes involved in glutathione regeneration. N-Acetyl-L-Cysteine (NAC) has been shown to protect against oxidative stress-induced neuronal death in cultured granule neurons.

Read the entire label and follow the directions carefully prior to use.

Take one (1) N-Acetyl-L-Cysteine (NAC) capsule one to three times daily with or without food, or as recommended by a healthcare practitioner.

Caution: Those who supplement with NAC should drink 6 to 8 glasses of water daily in order to prevent cysteine renal stones. Cysteine renal stones are rare but do occur.
