NAC And Fertility: Enhancing Reproductive Success

When it comes to fertility, the role of antioxidants cannot be overstated. Antioxidants help protect our cells from damage caused by harmful free radicals, and emerging research suggests that N-acetyl cysteine (NAC), a powerful antioxidant, may hold great promise in supporting reproductive health.

Let's explore the benefits of NAC for fertility as well as the potential link between NAC and increasing live birth rates.

Understanding NAC as an antioxidant:

N-acetyl cysteine (NAC) is a supplement derived from the amino acid cysteine. It acts as a precursor to glutathione, one of the body's most potent antioxidants. NAC helps boost glutathione levels, enabling the body to neutralize free radicals effectively. By doing so, NAC plays a crucial role in supporting overall health, including fertility.

Potential for reducing miscarriage rates:

Miscarriage, a devastating event affecting many couples, can sometimes be attributed to oxidative stress and inflammation. NAC's potent antioxidant properties help counteract these factors, potentially reducing the risk of miscarriage. Studies have shown that NAC supplementation may help improve the chances of successful pregnancy by addressing oxidative stress and supporting a healthy uterine environment.

Optimal levels of antioxidants are vital for reproductive success. NAC supplementation has been associated with increased live birth rates in women undergoing assisted reproductive technologies (ART), such as in vitro fertilization (IVF) or intrauterine insemination (IUI). By reducing oxidative stress and improving embryo quality, NAC may contribute to higher success rates in these fertility treatments.

NAC antioxidant benefits

Apart from its potential impact on miscarriage rates and live birth rates, NAC offers additional benefits to fertility and reproductive health. These include:

Ovarian Health: NAC may support ovarian function by reducing oxidative stress and improving the quality of eggs.

Male Fertility: NAC's antioxidant properties can also benefit male fertility by protecting sperm from oxidative damage and enhancing sperm quality.

PCOS Management: Polycystic ovary syndrome (PCOS) is a common hormonal disorder affecting women of reproductive age. NAC supplementation has shown promising results in managing PCOS symptoms, such as irregular periods and insulin resistance.

NAC antioxidant dosage and side effects:

While NAC holds potential benefits, it is essential to take it in the correct dosage and be aware of any possible side effects. The appropriate dosage of NAC may vary depending on individual needs and specific fertility concerns. It is recommended to consult with a qualified healthcare professional who can determine the most suitable dosage for you.

In terms of side effects, NAC is generally considered safe when used as directed. However, some individuals may experience mild gastrointestinal symptoms, such as nausea, vomiting, or diarrhoea.

Dietary sources of NAC antioxidants:
While NAC is available in supplement form, you can also incorporate natural food sources into your diet to boost your antioxidant intake. Foods rich in cysteine, such as poultry, eggs, yogurt, garlic, and onions, can help increase your body's NAC levels.

Consuming a balanced diet that includes a variety of fruits, vegetables, and whole grains will provide you with a wide range of antioxidants for optimal reproductive health.

We also recommend considering a NAC supplement such as Zita West NAC. This premium supplement is designed to be taken alongside the rest of our range and delivers the optimum 600mg N-Acetyl Cysteine per two capsule dose.

Common NAC FAQs:

1. Is NAC an antioxidant?

Yes, N-acetyl cysteine (NAC) is an antioxidant.

2. Can NAC be taken with other fertility treatments or medications?

NAC is generally considered safe to be taken alongside other fertility treatments and medications. However, we would always advise speaking with a healthcare professional before adding in a new supplement to your routine.

3. How long should I take NAC before expecting to see results in my fertility journey?

The time frame for experiencing results may vary among individuals. While some women may notice improvements in their fertility relatively quickly, others may require a more extended period of supplementation.

4. Can NAC be beneficial for women with unexplained infertility?

Unexplained infertility refers to cases where the cause of infertility cannot be identified through routine diagnostic tests. NAC's antioxidant properties may still offer potential benefits by addressing oxidative stress, improving overall reproductive health, and increasing the chances of conception. However, it is important to consult with a healthcare professional who can evaluate your situation and provide tailored recommendations.


N-acetyl cysteine (NAC) has emerged as a promising antioxidant supplement in the realm of fertility. Its ability to reduce oxidative stress, support a healthy uterine environment, and enhance embryo quality may contribute to reduced miscarriage rates and increased live birth rates. While NAC holds significant potential, it is essential to seek guidance from a healthcare professional to determine the appropriate dosage, address any potential side effects, and ensure its compatibility with other fertility treatments or medications.
