Origin & History
Cysteine is a sulfur-rich, semi-essential amino acid critical for protein synthesis, antioxidant defense, and cellular detoxification. Found abundantly in protein-rich foods like poultry, yogurt, and eggs, cysteine supports glutathione production, tissue repair, immune resilience, and respiratory clarity. Its molecular role in collagen and keratin formation also enhances skin, hair, and nail vitality.
“Modern biochemical compound without traditional medicinal history, though its fundamental role in protein structure and sulfur metabolism has long been recognized in biochemistry.”Traditional Medicine
Scientific Research
Extensive research published in journals such as Free Radical Biology & Medicine and Clinical Immunology highlights Cysteine's critical role as a glutathione precursor and its impact on antioxidant defense. Studies support its benefits for detoxification, immune function, and respiratory health, particularly in its N-Acetyl Cysteine (NAC) form.

Frequently Asked Questions
What is Cysteine and NAC?
Cysteine is a semi-essential amino acid vital for making proteins and the master antioxidant, glutathione. N-Acetyl Cysteine (NAC) is the stable, supplemental form of cysteine that the body can easily absorb and use to boost glutathione levels.
What is the best dose of NAC?
For general antioxidant support, a common dosage is 600 mg taken once or twice daily. For specific therapeutic goals, doses may be higher, but it's best to consult with a healthcare provider to determine the right amount for you.
Why does NAC smell bad?
NAC's characteristic 'rotten egg' smell is completely normal. It comes from the sulfur component of the cysteine molecule, which is essential for its powerful antioxidant activity. The smell is a sign of a potent, active product.
