Support your body's natural detox, so your hormones can find their balance.
Reign Life's NAC was created for women who want to address hormonal imbalance at its root — starting with the body's own detoxification and antioxidant systems. N-Acetyl Cysteine is one of the most versatile and evidence-backed supplements available, with a particularly compelling body of research behind its use in female hormonal health and PCOS specifically.
NAC works primarily as a precursor to glutathione — the body's master antioxidant — but its benefits extend well beyond detoxification. From insulin regulation and androgen balance to cycle support and skin health, NAC addresses several of the core mechanisms that drive hormonal disruption in women.
Inside Each Capsule
A single, powerful active ingredient with wide-ranging benefits for women's hormonal health:
- N-Acetyl Cysteine (NAC): A naturally occurring amino acid derivative and the most effective known precursor to glutathione synthesis in the body. NAC replenishes glutathione stores, supports liver detoxification, reduces oxidative stress and directly influences several of the hormonal pathways most relevant to women with PCOS and hormonal imbalance.
What NAC Does for Female Health
NAC has one of the strongest evidence bases of any supplement used in women's hormonal health. Its mechanisms are interconnected — addressing oxidative stress, inflammation, insulin resistance and androgen excess simultaneously, making it particularly well suited to the complex, multi-faceted nature of PCOS:
- Glutathione Production & Cellular Detox
NAC is the body's most direct pathway to producing glutathione — often called the master antioxidant. Glutathione is produced in every cell of the body and is responsible for neutralising free radicals, supporting liver detoxification and protecting cells from oxidative damage. Women with PCOS consistently show lower glutathione levels than women without the condition, suggesting that oxidative stress plays a significant role in driving hormonal disruption. By replenishing glutathione, NAC supports the body's ability to detox effectively and maintain cellular health.
- Insulin Sensitivity & Blood Sugar Balance
Insulin resistance is one of the most common and consequential features of PCOS, affecting up to 70% of women with the condition. Elevated insulin drives increased androgen production, disrupts ovulation and worsens almost every PCOS symptom. NAC has been shown to improve insulin sensitivity and reduce fasting insulin levels, helping to interrupt this cycle and create a more hormonal-friendly metabolic environment.
- Androgen Balance & Skin Health
By helping to reduce elevated insulin and testosterone levels, NAC directly addresses two of the most common drivers of PCOS-related skin concerns — acne and hirsutism. Lowering androgen excess reduces the stimulation of sebaceous glands and hair follicles, supporting clearer skin and reduced unwanted hair growth over time. Results typically develop gradually over consistent use.
- Ovarian Health & Cycle Regularity
Research into NAC's role in ovarian health is particularly promising. Studies have shown that NAC supplementation can improve ovulation rates and menstrual regularity in women with PCOS, with some research suggesting it may be comparable in effectiveness to Metformin for certain outcomes — without the associated side effects. NAC supports the health of the follicular environment, improving the conditions needed for regular ovulation.
- Progesterone Support & Uterine Health
NAC may support healthy progesterone levels by improving the quality of the luteal phase — the second half of the menstrual cycle during which progesterone dominates. Adequate progesterone is essential for a healthy uterine lining, regular periods and fertility. By supporting the hormonal conditions needed for a healthy luteal phase, NAC contributes to more balanced, predictable cycles.
- Liver Support & Oestrogen Detoxification
The liver plays a central role in metabolising and clearing used oestrogen from the body. When liver detoxification is compromised — by oxidative stress, poor diet or environmental toxin load — oestrogen can recirculate, contributing to oestrogen dominance, worsening PMS and hormonal imbalance. NAC supports liver function directly through glutathione replenishment, improving the body's ability to process and clear excess oestrogen efficiently.
- Inflammation Reduction
Chronic low-grade inflammation underlies many of the symptoms associated with PCOS and hormonal imbalance. NAC's antioxidant activity reduces the oxidative stress that drives inflammatory signalling, helping to calm the inflammatory environment that contributes to insulin resistance, hormonal disruption and immune dysregulation.
- Mood & Neurological Health
Glutathione depletion and oxidative stress in the brain are associated with anxiety, low mood and cognitive difficulties. By restoring glutathione levels and reducing neurological oxidative stress, NAC supports healthier neurotransmitter function and emotional stability — particularly relevant for women whose mood is significantly affected by their hormonal fluctuations.
