NAC (N-Acetyl L-Cysteine) is a powerful amino acid and precursor to glutathione, your body's master antioxidant. It works by replenishing glutathione levels in your cells, which helps support healthy lung function, breaks down excess mucus, and protects your respiratory system from environmental stressors like pollution and smoke. NAC has been used in hospitals since the 1960s for respiratory support.

Most customers report noticing improvements in their breathing and mucus clearance within the first 1-2 weeks of consistent use. However, individual results vary based on your current respiratory health and lifestyle factors. For optimal results, we recommend taking NAC daily for at least 60-90 days to experience the full benefits of improved glutathione levels and respiratory support.

Each capsule contains 600mg of pharmaceutical-grade NAC. The typical recommended dosage is 600-1800mg per day, which equals 1-3 capsules daily. We suggest starting with one capsule per day with food, then increasing to two capsules if needed based on your wellness goals. Always consult with your healthcare provider before starting any new supplement regimen.

NAC is generally well-tolerated by most people. Some individuals may experience mild digestive discomfort, nausea, or a sulfur-like odor (which is normal for NAC) when first starting. Taking NAC with food can minimize these effects. If you experience any adverse reactions, discontinue use and consult your healthcare provider. NAC is considered safe for long-term use when taken as directed.

NAC is generally safe to combine with most supplements. However, if you're taking medications for blood pressure, nitroglycerin, or blood thinners, consult your healthcare provider before use as NAC may interact with these medications. It's also recommended to take NAC at least 2 hours apart from activated charcoal, as charcoal may reduce NAC absorption.
