Key Health Benefits
| Benefit Area | Description of Clinical Trial Findings | PubMed Link |
|---|---|---|
| Respiratory health (COPD) | In a 1-year double-blind trial of stable COPD patients, high-dose NAC (600 mg twice daily) significantly improved small-airway function and reduced exacerbation frequency versus placebo. | PubMed (PMID: 23348146) |
| Liver health (NAFLD) | Among patients with nonalcoholic fatty liver disease, 3 months of NAC supplementation significantly lowered serum ALT (alanine aminotransferase) compared to an active control (vitamin C), indicating improved liver function. | PubMed (PMID: 22308119) |
| Kidney health (contrast nephropathy) | In acute myocardial infarction patients undergoing primary angioplasty, adding NAC (intravenous plus oral) markedly reduced contrast-induced acute kidney injury. The incidence of a ≥25% rise in serum creatinine was 33% in controls versus only 15% (standard NAC) and 8% (high-dose NAC). | PubMed (PMID: 16807414) |
| Immune support (influenza-like illness) | In a 6-month trial of elderly subjects, long-term NAC (600 mg twice daily) significantly attenuated influenza-like illness: NAC-treated subjects had fewer, less severe symptoms, and only 25% of NAC-treated infected individuals developed clinical illness versus 79% in the placebo group. | PubMed (PMID: 9230243) |
| Mental health (OCD) | In patients with treatment-resistant obsessive-compulsive disorder, adjunctive NAC (up to 2400 mg/day) significantly reduced OCD symptoms. By week 12, 52.6% of NAC-treated patients were full responders (≥35% Y-BOCS reduction) versus only 15% on placebo. | PubMed (PMID: 23131885) |

Questions & Answers
Have a Question?
-
May I take arjuna with NAC?
N-Acetyl L-Cysteine (NAC) and Arjuna (Terminalia arjuna) can generally be taken together. NAC supports healthy respiratory function, while Arjuna supports cardiovascular health. There are no known negative interactions between them. However, if you have any health condition or under medication, we suggest consulting your doctor before starting the supplement.
-
Is this product effective in skin brightening?
N-Acetyl L-Cysteine is known primarily for its antioxidant properties and its role in supporting liver function, respiratory health, and detoxification. It helps the body produce glutathione, one of the most powerful antioxidants that protect cells from oxidative stress and damage. While N-Acetyl L-Cysteine is not specifically marketed or known for direct skin brightening, its antioxidant effects can improve skin health over time by reducing oxidative stress, which contributes to signs of aging like dullness, hyperpigmentation, and uneven skin tone. By boosting glutathione levels, N-Acetyl L-Cysteine may indirectly promote a clearer, more radiant complexion, as glutathione is often linked to skin lightening and overall skin health.
-
Could it be used for pcos too?
Yes, absolutey! Research has shown that N-Acetyl L-Cysteine may improve insulin resistance, enhance ovulation, and reduce androgen levels which may contribute in managing PCOS. However, under any medical condition, we recommend consulting a healthcare professional before using the product. -
Does your N-Acetyl L-Cysteine come from animal sources or is it vegetarian? We bought it, but it has a funny odor.
N-Acetyl L-Cysteine is a vegetarian sulphur containing amino acid. As a result, the pungent odour is its characteristic smell resembling the presence of sulphur.
