N-Acetyl-L-Cysteine (NAC) is derived from L-cysteine‚ an amino acid which is a precursor to glutathione‚ an important antioxidant. Only a limited amount of glutathione is naturally present in the human body; therefore‚ it must be synthesized from cysteine.
NAC is the primary antioxidant produced by your body‚ and is involved in a number of crucial metabolic processes. It also plays an important role in protein synthesis‚ the activation of enzymes‚ and the synthesis and repair of your DNA. NAC is also a source of sulfur; sulfur metabolism is a key biological process in all living organisms‚ because it acts as a constituent of molecules like methionine‚ cysteine‚ and coenzyme-A‚ all of which are crucial in energy generation and enzymatic processes.
L-cysteine is relatively unstable‚ and often it is degraded during the process of absorption to the point where your body is not able to use it. NAC‚ however‚ is more stable‚ which is why it’s well-suited to supplements. After absorption‚ NAC is converted into L-cysteine‚ which increases cysteine levels throughout the body. Each tablet of Allergy Research Group’s NAC N-Acetyl-L-Cysteine contains this free-form amino acid in order to provide you with many health benefits.
