NAC N-Acetyl-L-Cysteine 1000 mg  – Glutathione (GSH) & Powerful Antioxidants, Liver Detox, Respiratory Comfort, Immunity & Cellular Energy

NAC N-Acetyl-L-Cysteine 1000 mg, Natural Factors provides a concentrated dose of N-acetyl-L-cysteine – the direct precursor of glutathione (GSH), the essential endogenous antioxidant “shield” for cellular protection, liver detoxification, and balanced response to oxidative stress. Each serving offers 1000 mg of NAC, a stable form of the amino acid L-cysteine, known for its good bioavailability and strategic role in GSH synthesis, thinning of respiratory secretions, support of immune function, and maintenance of efficient energy metabolism. The formula is designed for people with an active lifestyle, demanding periods, or increased environmental exposures, offering coherent support for the liver, lungs, immunity, and daily vitality.

Detailed benefits of NAC N-Acetyl-L-Cysteine 1000 mg

• Recharging glutathione – the first line of antioxidant defense

Glutathione (GSH) is the main intracellular antioxidant, indispensable for neutralizing free radicals and recycling other antioxidants (e.g., vitamins C and E). NAC provides cysteine, the rate-limiting component in GSH synthesis, which translates into:

✅ Increased endogenous antioxidant capacity
✅ Protection of lipids, proteins, and DNA against oxidation
✅ Redox balance in tissues subjected to oxidative stress

• Liver detoxification and metabolic clarity

The liver uses glutathione in the phases of biotransformation to neutralize reactive metabolites and xenobiotic compounds. By supporting GSH, NAC:

✅ Contributes to the conjugation and elimination of potentially toxic products
✅ Supports hepatic enzymes involved in detoxification
✅ Provides an antioxidant “background” useful during periods of metabolic demand

• Respiratory comfort and thinning of secretions

NAC is known for its mucolytic properties thanks to sulfur bonds that can break disulfide bridges in mucus, reducing the viscosity of secretions.

Functionally, this brings:
✅ Thinning and mobilizing secretions for respiratory comfort
✅ Support for freer breathing in the context of seasonal challenges
✅ Support for airway hygiene in daily routines

• Support for the immune system

An efficient immune system needs a balanced redox environment. With adequate glutathione reserves, immune cells can perform their functions optimally.

NAC intake:
✅ Favors a coordinated immune response and resilience to oxidative stress
✅ Contributes to maintaining the integrity of the respiratory barrier
✅ Supports antioxidant replenishment after demanding periods

• Protection for mitochondria and cellular energy

Oxidative stress affects mitochondrial components and the efficiency of ATP production. NAC, through GSH, helps:
✅ Stabilize the mitochondrial environment and reduce peroxidation
✅ Maintain energy flow and daily tone
✅ Improve resistance to fatigue on busy days

• Inflammatory balance and cellular recovery

Excessive oxidation amplifies pro-inflammatory pathways. By modulating redox status, NAC:
✅ Supports control of oxidative processes associated with inflammation
✅ Contributes to protecting tissues against environmental factors
✅ Ensures a favorable framework for recovery after effort

• Support for skin and tissues through collagen and sulfur

Cysteine is a sulfur donor, an important element for protein structures and disulfide bonds. Within a healthy antioxidant background:

✅ Stability of collagen and the extracellular matrix is supported
✅ Membrane lipids are protected against oxidation
✅ The integrity of tissues exposed to stress is supported

• Mental clarity and neuronal oxidative stress

The brain consumes a lot of oxygen and is sensitive to peroxidation. Through its role in GSH synthesis, NAC can:
✅ Contribute to the antioxidant defense of neurons
✅ Support clarity during periods of intense screen work
✅ Help maintain a stable mental state during demanding days

• Support in contexts of environmental exposure

Pollutants, smoke, reactive compounds – all can increase the demand for antioxidants. NAC, as a source of cysteine:
✅ Helps neutralize reactive species generated by exposures
✅ Favors the cells’ ability to manage environmental stress
✅ Complements healthy habits (fresh air, hydration, plant-rich diet)

• Smart nutritional synergies

NAC works well alongside:
✅ Vitamin C – regenerates antioxidants and improves redox status
✅ Selenium – cofactor for glutathione peroxidases
✅ Vitamin E and polyphenols – extend the antioxidant “net”
These synergies help maintain a robust oxidative–antioxidant balance.

• Suitable for modern lifestyles

Long office hours, workouts, commuting, travel – all challenge the body’s defense mechanisms. NAC:
✅ Provides an antioxidant “reserve” where needed
✅ Contributes to a balanced immune response
✅ Supports the liver and lungs for an easier day

• How this formula differs

Unlike classic exogenous antioxidants, NAC acts “from within” by increasing glutathione – the cell’s universal antivirus.

Advantages:
✅ Endogenous approach to antioxidant protection
✅ Versatility: hepatic, respiratory, immune, cellular
✅ Compatibility with health- and performance-oriented routines

• Lifestyle framework for consistent results

NAC’s effects are maximized within a lifestyle hygiene context:
✅ A diet rich in colorful plants, sources of selenium, and antioxidant vitamins
✅ Steady hydration and ventilation of workspaces
✅ Moderate movement to stimulate circulation and oxygenation
Together, these habits multiply the benefits of a balanced redox status.

NAC N-Acetyl-L-Cysteine 1000 mg, Natural Factors is a direct solution to support glutathione, protect cells, and maintain respiratory and metabolic clarity in the fast pace of modern life. With 1000 mg NAC per serving, the formula provides endogenous antioxidant protection, liver detox, respiratory comfort, immunity, and cellular energy – precise support for those pursuing performance, resilience, and long-term well-being.
