NAC Nasal Spray

NAC nasal spray is designed to support glutathione production, oxidative balance, respiratory clarity, and cellular resilience. NAC (N-Acetyl-L-Cysteine) is a direct precursor to glutathione, the body’s primary intracellular antioxidant, making it foundational for recovery, detoxification support, and protection against everyday oxidative stress.

NAC nasal spray is absorbed through the nasal mucosa, bypassing digestion and first-pass liver metabolism. This supports:

- Faster and more predictable absorption
- Reduced digestive variability
- Targeted support for the nasal and upper respiratory environment

For individuals who prefer non-oral delivery or want more immediate support, nasal administration offers a practical alternative to capsules or powders.

Glutathione production depends on cysteine availability, and NAC supplies bioavailable cysteine, the rate-limiting building block for glutathione synthesis. By supporting NAC levels, this spray helps the body maintain healthy glutathione production, which is essential for antioxidant defense, detoxification pathways, and cellular recovery.

Yes. NAC has been widely studied for its mucolytic properties, meaning it supports the normal breakdown and clearance of mucus. When delivered intranasally, NAC helps support nasal and upper respiratory comfort, particularly during environmental, seasonal, or air-quality challenges.

No. NAC nasal spray is stimulant-free and does not act like caffeine or other energy boosters. Any improvements in energy or clarity are related to cellular efficiency, reduced oxidative stress, and improved recovery, not nervous system stimulation or forced energy output.

Yes. NAC nasal spray integrates easily into the Sync Stack and pairs especially well with:

- Glutathione Nasal Spray for direct antioxidant support
- NAD+ or Enhanced NMN for cellular energy and repair
- Methyl B12 for neurological and metabolic support
- Forage or adaptogenic blends for stress resilience

Many people use NAC daily or situationally during periods of high stress, travel, intense training, or environmental exposure.
