N-acetyl cysteine (NAC) has been widely studied for its potential role in supporting reproductive and metabolic health. A 2023 systematic review and meta-analysis of clinical studies observed that NAC supplementation was associated with changes in key reproductive hormones, including reduced total testosterone and increased follicle-stimulating hormone (FSH) levels.
Further research has explored NAC’s impact on metabolic markers, finding associations with improved fasting blood glucose, lipid balance, and antioxidant activity. These findings suggest that NAC may play a supportive role in the body’s natural processes involved in energy metabolism, hormone balance, and general wellbeing.
- Studied for its role in supporting healthy hormone activity
- Explored for potential benefits on ovulatory function
- Shown in research to influence reproductive hormone levels in women with PCOS
