  • NAC is a sulfur-containing amino acid involved in glutathione synthesis. Cysteine is a semi-essential amino acid.

    It is s considered semi-essential because your body can produce it from other amino acids, namely methionine, and serine. It becomes essential only when the dietary intake of methionine and serine is low.

    Cysteine is found in most high-protein foods, such as chicken, turkey, yogurt, cheese, eggs, sunflower seeds, and legumes.

    N-acetyl cysteine (NAC) is a supplement form of cysteine.

    Consuming adequate cysteine and NAC is important for a variety of health reasons — including replenishing the most powerful antioxidant in your body, glutathione. These amino acids also help with chronic respiratory conditions, fertility, and brain health.
