PRO NAC – N-Acetyl-L-Cysteine 600 mg

Targeted Daily Support for Glutathione Production, Antioxidant Defense, Respiratory Health, and Cellular Wellness

PRO NAC by PRO Therapeutics provides 600 mg of N-Acetyl-L-Cysteine (NAC) per vegan capsule in a focused daily antioxidant-support formula.

NAC is a derivative of the amino acid L-cysteine and serves as a precursor to glutathione, one of the body's most important naturally occurring antioxidants.

By supporting cysteine availability and glutathione synthesis, NAC helps maintain normal cellular antioxidant defenses, oxidative balance, and healthy immune function. NAC also has well-established mucolytic properties relevant to respiratory health.

Each bottle contains 60 vegan capsules, providing a 60-day supply at one capsule daily or a 30-day supply at two capsules daily.

At PRO Therapeutics, NAC is positioned as a foundational nutritional supplement for individuals focused on cellular health, antioxidant support, respiratory wellness, and long-term health optimization.

Key Benefits

Supports Glutathione Production

Glutathione is a naturally occurring tripeptide composed of glutamate, cysteine, and glycine. It plays an important role in cellular antioxidant defense, redox regulation, and normal cellular function.

Cysteine availability can influence glutathione synthesis. NAC serves as a source of cysteine and has been studied for its ability to support glutathione availability.

NAC is therefore positioned as nutritional support for endogenous glutathione production rather than a treatment for glutathione deficiency or oxidative-stress-related disease.

Potential benefits include:

• Supporting normal glutathione synthesis

• Providing a source of cysteine for antioxidant production

• Helping maintain cellular redox balance

• Supporting normal antioxidant defense mechanisms

Supports Cellular Antioxidant Defense

Oxidative stress occurs when the generation of reactive oxygen species exceeds the capacity of antioxidant defense systems to maintain normal cellular balance.

NAC contributes to antioxidant physiology primarily through its role as a cysteine donor and glutathione precursor. Its chemical properties also allow it to participate in certain reactions involving reactive species and disulfide bonds.

These mechanisms have made NAC an extensively investigated compound in cellular biology and clinical medicine.

Potential benefits include:

• Supporting normal cellular antioxidant capacity

• Helping maintain healthy redox signaling

• Providing nutritional support during everyday oxidative demands

• Supporting normal cellular maintenance and function

Supports Respiratory Health

NAC has established mucolytic properties, meaning it can reduce mucus viscosity by disrupting disulfide bonds within mucus proteins.

This mechanism has been investigated in patients with chronic respiratory conditions, although clinical outcomes vary based on formulation, dosage, population, and underlying disease.

For general supplementation, PRO NAC is positioned as respiratory wellness support rather than treatment for chronic obstructive pulmonary disease, asthma, infection, or other respiratory disorders.

Potential benefits include:

• Supporting normal respiratory mucus clearance

• Helping maintain healthy mucus properties

• Supporting normal respiratory tract function

• Complementing broader respiratory wellness strategies

Supports Immune Function

Glutathione participates in normal immune-cell signaling, antioxidant protection, and the maintenance of cellular redox balance.

Because NAC supplies a precursor for glutathione synthesis, it has been investigated for potential effects on immune-cell function and oxidative balance.

Although these mechanisms are biologically relevant, evidence does not establish that routine NAC supplementation prevents infections or improves immune outcomes in otherwise healthy individuals.

Potential benefits include:

• Supporting normal glutathione-dependent immune-cell function

• Helping maintain cellular antioxidant protection

• Supporting normal immune-related redox signaling

• Complementing comprehensive nutritional immune support

Supports Cellular Health and Recovery

Normal cellular recovery depends on adequate nutrient availability, healthy antioxidant defenses, and the maintenance of cellular homeostasis.

NAC has been studied in multiple physiological and clinical settings because of its involvement in glutathione synthesis and antioxidant pathways.

However, evidence for meaningful improvements in exercise recovery or athletic performance from routine NAC supplementation remains limited and inconsistent.

Potential nutritional benefits include:

• Supporting normal cellular antioxidant systems

• Helping maintain healthy cellular function

• Supporting antioxidant balance during physiological demands

• Complementing nutrition, training, and recovery routines

Why 90 Days?

Consistency Before Complexity

Antioxidant-support supplementation is best considered within a broader approach to nutrition, exercise, recovery, and long-term wellness.

The 90-Day Supply at two capsules daily provides three consecutive monthly bottles, allowing individuals to maintain the same daily NAC intake throughout a structured three-month program.

Month 1
