N-Acetyl Cysteine (NAC) – Potent Antioxidant for Fertility and Pregnancy

£16.95

N-Acetyl Cysteine (NAC) is a science backed antioxidant supplement that replenishes glutathione, reduces oxidative stress and supports egg and sperm quality, hormone regulation and high-risk pregnancy needs, all in a convenient once-daily 600mg capsule.


NAC is an antioxidant and anti-inflammatory suitable for both men and women. By replenishing intracellular glutathione, NAC helps reduce oxidative stress, a key factor in egg and sperm damage. Women may benefit from improved ovulation and insulin regulation (especially with PCOS), while men gain protection for sperm function and DNA integrity. NAC also offers extra support in high-risk pregnancies.

What is NAC? 


NAC is a bioavailable precursor to glutathione, the body’s “master antioxidant.” It boosts cellular defences against free radicals and supports detoxification pathways critical to reproductive cell health.


Studies indicate that NAC can reduce inflammation, regulate hormones and support regular cycles, meaning it can be beneficial for those with PCOS.


In men, NAC can positively impact sperm health, including factors like motility, count, and morphology.


Emerging research also suggests that NAC can be beneficial and give additional support for individuals with high-risk pregnancies.


 How does NAC work? 


By raising glutathione levels, NAC neutralises harmful oxidants, reduces inflammation and supports hormone-regulating mechanisms, creating a healthier environment for egg maturation and sperm production.

Who is it for?

Why take N-Acetyl Cysteine (NAC) for fertility?

Oxidative stress and inflammation can impair gamete quality and hormone balance. NAC helps counter these factors, making it valuable for anyone facing age-related decline, PCOS-related irregularity or sperm-quality issues.


Why take N-Acetyl Cysteine (NAC) during early pregnancy?

NAC is often recommended for individuals with high-risk pregnancies, due to its potential in reducing oxidative stress, regulating hormonal imbalances, improving endometrial health, and exerting anti-inflammatory effects.


When should I start taking N-Acetyl Cysteine (NAC)?

For best results, begin NAC at least three months before trying to conceive to cover both egg and sperm development cycles.
