Natural Factors N-Acetyl-L-Cysteine Amino Acid 500 mg (90 Capsules)

Natural Factors N-Acetyl-L-Cysteine (NAC) delivers 500 mg of pharmaceutical-grade N-Acetyl-L-Cysteine per capsule, providing a highly bioavailable form of this important sulfur-containing amino acid derivative. NAC serves as a direct precursor to glutathione, one of the body’s most significant endogenous antioxidants, and is widely used to support overall antioxidant status.

Each batch is manufactured to pharmaceutical-grade standards, reflecting Natural Factors’ commitment to purity and potency. The formula is kept clean and straightforward, using only minimal, well-tolerated excipients and a vegetarian capsule shell — making it suitable for vegetarians and those following a gluten-free diet.

With 90 capsules per container and a flexible dosage of one capsule two to three times per day, this product offers a convenient and consistent way to incorporate NAC into your daily supplement routine.
