N-Acetyl-L-cysteine (NAC) is an essential amino acid with significant antioxidant properties. This compound aids in protein formation and glutathione production, offering benefits such as reduced muscle fatigue, decreased inflammation, and accelerated recovery, making it ideal for athletes. NAC may also minimize chemotherapy side effects and reduce risks of heart issues and infections. Cysteine, the key component of NAC, supports the strengthening of hair, nails, and skin. Additionally, it acts as a mucolytic and is part of respiratory treatments and liver detoxification protocols. Each Solaray capsule contains 295 mg of NAC. For optimal effect, it is recommended to take one capsule daily outside meals.
