N-Acetyl-L-Cysteine
Life Extension

Life Extension's N-Acetyl-L-Cysteine supplement provides a high-quality source of N-acetyl-L-cysteine (NAC), a powerful antioxidant and precursor to glutathione, one of the body's most important antioxidants. NAC plays a critical role in detoxification processes and helps maintain respiratory health by supporting the thinning of mucus in the lungs. This supplement is designed to support cellular protection against oxidative stress and promote overall immune system function.
The active ingredient, N-acetyl-L-cysteine, works by replenishing intracellular glutathione levels, which can be depleted by environmental toxins, stress, and aging. The inactive ingredients, including silica, vegetable cellulose, and vegetable stearate, serve as safe, non-reactive components that ensure the stability and bioavailability of the capsule without introducing allergens or artificial additives.
People commonly use NAC supplements to support liver detoxification, respiratory health, and antioxidant defenses. It is also popular among individuals looking to enhance immune resilience and protect cells from oxidative damage. This supplement is suitable for those seeking a natural way to support their body's detox pathways and maintain healthy lung function.
Life Extension's formulation is free from common allergens and artificial fillers, making it a clean and reliable choice for daily supplementation. As with any supplement, it is recommended to consult a healthcare professional before use, especially for individuals who are pregnant, nursing, or have underlying health conditions.
Ingredients
Inactive Ingredients
Silica, or silicon dioxide, is a naturally occurring mineral essential for the synthesis of collagen, supporting skin elasticity, joint health, and bone strength. It also contributes to cardiovascular wellness by promoting arterial flexibility and has antioxidant properties that combat oxidative stress. While generally safe, excessive supplementation may cause gastrointestinal issues and interact with certain medications, so consultation with a healthcare provider is recommended.
Vegetable cellulose is a plant-derived dietary fiber that supports gut health, regulates blood sugar, and aids weight management by acting as a bulking agent in the digestive system. It promotes regular bowel movements, enhances satiety, and fosters a healthy gut microbiome through fermentation by beneficial bacteria. Generally safe with low risk, it should be introduced gradually to avoid gastrointestinal discomfort and used cautiously by individuals with certain medical conditions.
Vegetable stearate is a fatty acid derived from plant sources like palm or coconut oil, commonly used as a lubricant in supplement and tablet manufacturing. It supports digestive health by enhancing nutrient absorption and may have anti-inflammatory effects in the gut, promoting better overall wellness. Generally safe, it should be used with caution in individuals with sensitivities or those on medications.
