Nutrients and Bioactive Compounds in PCOS Management: An Overview

Introduction

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age, characterized by a complex array of symptoms. Given that current management primarily focuses on symptom control, there is a continuous search for complementary therapeutic strategies. This narrative review investigates the potential role of various nutrients and bioactive compounds in ameliorating PCOS manifestations.

The Study in Detail

The review, titled "Nutrients and bioactive compounds in polycystic ovary syndrome: updated insights into effects and underlying mechanisms," was published in Frontiers in Nutrition in February 2026 by Zhang Y, Shi B, Tian Y, Xu S, and Chang H from Heilongjiang University of Chinese Medicine. This narrative review synthesized existing evidence regarding the impact of specific nutrients and bioactive compounds on PCOS.

The authors highlight that women with PCOS frequently exhibit deficiencies in various vitamins and minerals, which are often linked to insulin resistance and endocrine disturbances characteristic of the syndrome. The review suggests that nutritional supplementation could offer significant adjunctive benefits to conventional therapies.

Key findings indicate that specific vitamins (e.g., E, K, D, B8, B9, B12), minerals (e.g., selenium, chromium, zinc, calcium, magnesium), and other bioactive compounds (e.g., melatonin, omega-3 polyunsaturated fatty acids, coenzyme Q10, N-acetylcysteine) may improve core PCOS symptoms. The proposed mechanisms of action include:

• Regulating glucose and lipid metabolism.
• Correcting hormonal imbalances.
• Attenuating oxidative stress and chronic inflammation.
• Beneficially modulating gut microbiota composition.

The review consolidates current knowledge on these nutritional interventions, elucidates their potential mechanistic pathways, and discusses their clinical applicability, aiming to inform integrative management and future research directions.

Assessment

This narrative review provides a comprehensive overview of the current understanding of how various nutrients and bioactive compounds might influence PCOS. Its strength lies in synthesizing a broad range of evidence, offering a holistic perspective on potential adjunctive therapies. By detailing the proposed mechanisms, the review contributes to a deeper understanding of PCOS pathophysiology and how nutritional interventions might target these pathways.

However, as a narrative review, it primarily summarizes existing literature without conducting a systematic analysis or meta-analysis, which means it does not quantitatively assess the strength of evidence for each nutrient. The clinical applicability discussed, while insightful, would benefit from further robust clinical trials to confirm efficacy and establish optimal dosages and treatment protocols for these compounds in a PCOS population.

Practical Relevance

For individuals with PCOS, this review underscores the potential importance of nutritional status and targeted supplementation as part of a comprehensive management plan. While conventional medical treatments remain crucial, addressing potential deficiencies in vitamins and minerals like Vitamin D, B vitamins, magnesium, and zinc, or incorporating bioactive compounds such as omega-3 fatty acids and CoQ10, could offer additional support in managing symptoms like insulin resistance, hormonal imbalances, and inflammation.

It emphasizes that dietary choices and, where appropriate, carefully considered supplementation under professional guidance, might play a significant role in improving overall health and quality of life for women with PCOS. This aligns with the growing recognition of personalized nutrition in managing chronic conditions.

Conclusion

This review highlights the emerging evidence for specific nutrients and bioactive compounds as valuable adjunctive therapies in the management of Polycystic Ovary Syndrome. By influencing metabolic, hormonal, inflammatory, and gut health pathways, these compounds offer promising avenues for symptom amelioration. Further research, particularly in the form of well-designed clinical trials, is warranted to solidify these findings and translate them into standardized clinical practice.
