Most supplements are studied for one thing. NAC has been studied for several, and the research behind it is some of the most compelling in women's hormonal health.

 

Whether you are focused on your cycle, your skin, your weight, your fertility, or simply feeling better day to day - NAC has been studied across more areas of PCOS health than almost any other single supplement.

 

Published research has explored its role in:

 

  • Ovulation and reproductive health
  • Balancing Sex hormone, including testosterone
  • Normal blood sugar function
  • Antioxidant activity and oxidative stress
  • Normal inflammatory response

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.

Frequently Asked Questions

The dose of NAC used in clinical trials has ranged from about 600 mg to 3,000 mg per day, typically divided into two or three servings. Generally because most customers are taking other products also, only one capsule per day is generally needed.

The odour you smell is likely from the sulphur that is part of NAC (N-acetyl-cysteine), this is completely normal and why it is in a capsule and not a powder.
