NAC N-Acetyl Cysteine 1000 mg – Cellular detoxification, antioxidant protection, respiratory health and liver support for sustainable daily vitality

NAC 1000 mg from Swanson is a high-purity dietary supplement containing N-acetyl cysteine (NAC) – a stable form of the amino acid L-cysteine, recognized for its essential role in glutathione production, the body's main internal antioxidant. Glutathione is involved in protecting cells against oxidative stress, supporting liver functions, body detoxification and maintaining respiratory system health. Through its concentrated intake, NAC supports cellular regeneration, metabolic energy and redox balance – that is, the balance between oxidative and antioxidant processes in the body.

Due to its broad spectrum of action, NAC is used to support the liver, lungs, immunity, brain function and body recovery after metabolic stress or toxin exposure. It is a key supplement for general vitality, longevity and daily biochemical balance.

Detailed Benefits of NAC (N-Acetyl Cysteine) 1000 mg

• Supporting glutathione synthesis – the body's antioxidant shield

Glutathione (GSH) is considered the "longevity molecule" due to its essential role in cellular protection. NAC is the main precursor of glutathione, providing the amino acid cysteine – an indispensable element in reactions neutralizing free radicals and toxins.

By increasing glutathione levels, NAC contributes to:
✅ Neutralizing oxidative stress caused by pollution, processed food and chronic stress
✅ Regenerating cells affected by free radicals
✅ Maintaining redox balance in liver, kidneys, heart and brain
An optimal glutathione level helps the body defend itself effectively against premature aging and chronic inflammation.

• Advanced liver detoxification and metabolic protection

The liver is the main detoxification organ, responsible for neutralizing harmful substances. NAC supports liver enzymes involved in transforming fat-soluble toxins into water-soluble compounds, easy to eliminate.

✅ Support for liver cell regeneration (hepatocytes)
✅ Protection against accumulation of heavy metals and pollutants
✅ Supporting the natural detoxification process after demanding periods (medications, metabolic stress, unbalanced diet)
Through this mechanism, NAC contributes to maintaining a healthy liver and functional metabolism, essential for energy and vitality.

• Respiratory protection and lung health support

NAC is recognized for its ability to thin mucus and support respiratory functions. It acts by breaking disulfide bonds in mucus, facilitating secretion elimination and keeping airways clear.

✅ Support for easy breathing and chest comfort
✅ Natural clearing of airways from particles and impurities
✅ Reduction of oxidative stress at lung level, useful for people exposed to pollution or irritating environments
NAC thus contributes to respiratory system protection and maintaining optimal tissue oxygenation.

• Immune balance and protection against oxidative stress

By stimulating glutathione production, NAC strengthens immune system functions and helps white cells respond effectively to external challenges.

✅ Increases the body's natural resistance
✅ Protects immune cells against free radicals
✅ Supports recovery after periods of physical demand or infections
A balanced immune system is the foundation of vitality and functional longevity.

• Support for cognitive functions and mental well-being

The brain is extremely sensitive to oxidative stress. NAC contributes to neuron protection by increasing glutathione levels at brain level and by regulating neurotransmitter balance (especially dopamine and glutamate).

✅ Supports mental clarity and concentration capacity
✅ Supports emotional balance and state of calm
✅ May contribute to reducing sense of mental fatigue associated with oxidative stress
Thus, NAC becomes a trusted ally for brain health and daily cognitive performance.

• Cellular regeneration and mitochondrial protection

Mitochondria are the "power plants" of the cell. Oxidative stress can damage them, lowering energy levels and accelerating the aging process. NAC contributes to maintaining optimal mitochondrial function by reducing lipid peroxidation and restoring endogenous antioxidants.

✅ Support for ATP production – clean cellular energy
✅ Protection of mitochondria against free radicals
✅ Tissue recovery during periods of metabolic stress
Through these effects, NAC supports a stable level of energy and cellular performance.

• Inflammatory balance and longevity support

Chronic inflammation at cellular level is one of the main causes of accelerated aging. NAC helps regulate inflammatory response by controlling oxidative stress and protecting cellular DNA.

✅ Reduces accumulation of free radicals in tissues
✅ Protects DNA against oxidative deterioration
✅ Supports long-term cellular regeneration
Through these mechanisms, NAC becomes a key supplement in modern strategies for maintaining biological youth.

• Supporting metabolism and energy balance

NAC indirectly contributes to maintaining balanced metabolism by optimizing liver functions and enzymes that participate in carbohydrate and fat processing.

✅ Support for efficient energy metabolism
✅ Prevention of metabolic toxin accumulation
✅ Contribution to sense of daily vitality
A well-regulated metabolism translates to better general state and stable tone.

• Synergies and excellent compatibility with other supplements

NAC works synergistically with:

Vitamin C – regenerates oxidized glutathione and amplifies antioxidant protection.
Selenium and zinc – cofactors in glutathione synthesis.
Vitamin B6 and magnesium – support NAC conversion into biologically active forms.
Coenzyme Q10 and alpha-lipoic acid (ALA) – protect mitochondria and support energy regeneration.

✅ Complete stack for detoxification, energy and immunity
✅ Compatible with modern diets and antioxidant regimens
✅ Easy to integrate into daily routine for cumulative results

• Formulistic minimalism and total traceability

NAC 1000 mg, Swanson, contains a single active ingredient – pure N-acetyl cysteine, without additives, colorants or GMOs. The simple formula guarantees predictability and high bioavailability.

✅ Single ingredient, transparent dosage
✅ Pharmaceutical quality, tested for purity
✅ Suitable for constant use in wellness routines

• Target audience and usage contexts

NAC is suitable for active adults, people exposed to stress, pollution or oxidative fatigue, professionals with intense schedules and users who want comprehensive body support.

✅ Professionals in urban environments with increased oxidative stress
✅ People concerned about liver, lung and immunity health
✅ Users seeking a solid antioxidant base for daily vitality
✅ Complement for those adopting a periodic detoxification routine

NAC 1000 mg, Swanson offers complete support for internal cleansing, redox balance and cellular protection. By restoring glutathione reserves, NAC acts as a "biological filter" of the body, supporting the liver, lungs, immunity, brain and daily energy – an essential foundation for a resilient and vital body in the rhythm of modern life.
