Boosts Cellular Glutathione Levels

  • Dietary Supplements

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. NAC is an antioxidant and a free radical-scavenging agent that increases intracellular glutathione at the cellular level. NAC can act as a precursor for glutathione synthesis as well as a stimulator of the cytosolic enzymes involved in glutathione regeneration. NAC has been shown to protect against oxidative stress-induced neuronal death in cultured granule neurons.

N-acetyl-L-cysteine is a highly bioavailable nutrient that supports bronchial and respiratory health. N-acetyl-L-cysteine supports healthy glutathione levels at the cellular level. Glutathione is a potent antioxidant which helps protect neurons from oxidative stress and insults from foreign compounds. N-acetyl-L-cysteine also offers powerful support for liver and immune function.

Glutathione — oxidant defense at the cellular level

N-acetyl-L-cysteine is an easily-absorbed nutrient with potent benefits for whole body health.1 N-acetyl-L-cysteine is also the chemical precursor to glutathione.2-4 Glutathione is a powerful antioxidant which protects cells from free radical damage. It also defends against insults from foreign compounds at the cellular level and protects vulnerable neurons from oxidative stress.

Liver support, immune health, and more

Because of its quick absorption rate, N-acetyl-L-cysteine is a potent nutrient in its own right. This compound supports healthy respiratory function as well as bronchial health. N-acetyl-L-cysteine encourages healthy liver function and promotes immune system health as well.5-9 And more than 30 placebo-controlled studies on cellular glutathione have shown that N-acetyl-L-cysteine can favorably affect energy production, well-being, and quality of life.
