5 of the best supplements for PCOS

5 Of the Best Supplements For PCOS (based on Current Research) 


Polycystic Ovary Syndrome (PCOS) is a complex hormonal disorder that affects countless women worldwide in 2023. It's characterised by a range of symptoms, including irregular periods, hormonal imbalances, ovarian cysts, and often, difficulties with fertility. This multifaceted condition not only impacts reproductive health but can also lead to metabolic disturbances and an increased risk of developing conditions like type 2 diabetes and cardiovascular disease.

Lifestyle changes such as adopting a balanced and nutrient-rich diet, engaging in regular physical activity, managing stress, and ensuring adequate sleep are fundamental in managing PCOS. These steps contribute to weight management, hormone regulation, and overall health. However, beyond these lifestyle adjustments, emerging research highlights the potential benefits of specific supplements in enhancing PCOS management.

In this article, we’ll try to explore the world of PCOS supplements, exploring five of the best options backed by current research. These supplements are not standalone solutions, but rather valuable additions to a holistic approach that encompasses lifestyle changes, medical guidance, and personalised care.


1. Inositol 

Inositol, a naturally occurring compound, belongs to the vitamin B complex family and plays a crucial role in various cellular functions. While it exists in different forms, myo-inositol and D-chiro-inositol have garnered considerable attention due to their potential in addressing PCOS-related concerns.

Impact on Insulin Sensitivity 

One of the key hurdles faced by up to 70% of women with PCOS is insulin resistance, a condition in which cells become less responsive to the hormone insulin, leading to elevated blood sugar levels. Myo-inositol has demonstrated its ability to enhance insulin sensitivity, aiding the body in utilising glucose more effectively. By doing so, it helps to tackle the root cause of insulin resistance, which is often a driving force behind many PCOS symptoms.

Furthermore, inositol's influence extends to hormonal equilibrium. Hormonal imbalances are a hallmark of PCOS, contributing to irregular periods, excessive androgen levels, and other issues. Both myo-inositol and D-chiro-inositol have shown promise in restoring hormonal balance by modulating the production of key hormones like luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This balancing act contributes to more regular menstrual cycles and improved ovulatory function.

Evidence from Recent Studies 

The efficacy of inositol in the context of PCOS management is supported by a growing body of research. One significant study, published in the National Institutes of Health.Gov, showcased the efficacy of myo-inositol supplementation in addressing key aspects of PCOS. This study demonstrated that myo-inositol supplementation led to notable improvements in insulin resistance, hormone levels, and ovulation frequency among PCOS patients.

The results of this research underscore the potential of myo-inositol as a valuable tool in mitigating some of the fundamental challenges associated with PCOS. By effectively addressing insulin resistance, which is a common underlying factor in PCOS, myo-inositol could contribute to restoring hormonal balance and improving ovulatory function.

Furthermore, findings from a BioMed Central Ltd article, written by researchers from Endocrinology and Metabolism Department - Brest University Hospital, contribute to the growing body of evidence supporting the same role of myo-inositol in PCOS management. This particular study emphasized the benefits of myo-inositol in enhancing insulin sensitivity and fostering a greater likelihood of spontaneous ovulation. These outcomes underline the potential of myo-inositol to directly impact hormonal regulation and fertility-related issues in individuals with PCOS.

Given its natural origin and limited reported side effects, myo-inositol shows tremendous promise as a complementary approach for individuals seeking to address the complex challenges of PCOS. The research suggests that myo-inositol could play a pivotal role in promoting better metabolic and reproductive outcomes, potentially offering a more balanced and manageable experience for women dealing with PCOS.


2. L-Carnitine 

L-Carnitine, often referred to as the "fat-burning" molecule, plays a crucial part in transporting fatty acids into the cells' mitochondria—the powerhouses responsible for producing energy. While the body naturally produces L-Carnitine, it can also be obtained through dietary sources such as red meat, dairy, and certain plant-based foods. However, the supplement form of L-Carnitine offers a concentrated dose that could be particularly advantageous for those seeking targeted effects.

Understanding L-Carnitine's Role 

L-Carnitine's primary function in the body revolves around energy metabolism. It facilitates the transport of long-chain fatty acids into the mitochondria, where these fatty acids are oxidised to generate energy. This process not only supports overall cellular energy production but also has implications for various bodily functions, including muscle function, heart health, and even reproductive processes.

In recent years, researchers have been exploring L-Carnitine's potential impact on fertility, with a specific focus on egg quality. Egg quality, a key determinant of successful conception and healthy pregnancy, tends to decline as women age. This decline can result in chromosomal abnormalities, reduced fertilisation rates, and an increased risk of miscarriage.

Mitochondrial Function and Egg Quality 

The role of mitochondria in egg quality cannot be ignored as well. These tiny organelles are responsible for producing adenosine triphosphate (ATP), the primary energy currency of cells. Mitochondrial dysfunction can lead to a decrease in energy production and an increase in the generation of reactive oxygen species (ROS), which can cause oxidative stress and damage cellular components, including DNA.

L-Carnitine's involvement in mitochondrial function makes it a potentially valuable player in promoting egg quality. By aiding in the efficient transport of fatty acids into the mitochondria, L-Carnitine may contribute to enhanced energy production and reduced oxidative stress within the egg cells. This, in turn, could translate to improved egg quality and a higher likelihood of successful fertilisation and embryo development.


3. Vitamin D 

Amidst other major PCOS supplements, the significance of Vitamin D—the so-called "sunshine vitamin"—cannot be overstated, especially for women dealing with the complexities of PCOS. Beyond its well-known role in bone health, Vitamin D plays a vital part in hormonal balance and immune function, shedding light on its potential as a key player in managing PCOS.

Link Between Vitamin D Deficiency and PCOS 

The prevalence of Vitamin D deficiency has been a cause for concern in recent years, and intriguingly, this deficiency appears to intersect with the world of PCOS. Studies have suggested a correlation between low Vitamin D levels and a higher prevalence of PCOS. While the exact nature of this link is still being explored, the potential impact of Vitamin D on the intricate hormonal milieu of PCOS is becoming increasingly apparent.

Influence on Hormone Production and Immune Function 

Vitamin D exerts its influence through the Vitamin D receptor (VDR), which is found in various tissues, including those involved in hormonal regulation. This receptor allows Vitamin D to modulate the expression of genes related to hormone production and immune responses. In the context of PCOS, Vitamin D's influence on hormones like insulin, sex hormones, and anti-inflammatory markers becomes particularly relevant.

4. Zinc 

Zinc is not just another nutrient—it's a vital mineral with a multitude of roles in the body. It plays a central role in supporting immune function, aiding in wound healing, and even contributing to DNA synthesis. This trace mineral is found in a variety of foods, including meat, seafood, nuts, and legumes, making it accessible through a balanced diet. However, zinc's significance extends beyond these individual roles, encompassing its potential to impact PCOS.

The Impact of Zinc Deficiency on PCOS 

Zinc deficiency can be particularly detrimental for women with PCOS. This deficiency has been linked to increased oxidative stress—a state in which the body's delicate balance between harmful free radicals and protective antioxidants is disrupted. Oxidative stress can worsen inflammation and contribute to the hormonal imbalances that are often characteristic of PCOS.

Zinc's absence can also negatively affect the production and regulation of sex hormones, including insulin and androgens. These imbalances can further exacerbate PCOS symptoms, from irregular menstrual cycles to hirsutism (excessive hair growth) and acne.

Recent Research and Zinc Supplementation 

Recent studies have gone into the potential benefits of zinc supplementation for managing PCOS. An article published in the ScienceDirect  explored the impact of zinc supplementation on PCOS-related inflammation. The study demonstrated that zinc supplementation led to a reduction in inflammatory markers in women with PCOS, suggesting its potential to mitigate the chronic inflammation that often accompanies the condition.


5. Omegas 

Omega-3 fatty acids are unsaturated fats that are integral to our health. This fat is not produced by the body and must be obtained through dietary sources or supplementation. Among the various types of omega-3s, eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA) are particularly prominent due to their roles in promoting heart health, brain function, and yes, inflammation control.

However, beyond their well-known benefits for heart health and brain function, omega-3 fatty acids also play a significant role in supporting metabolic health and optimizing lipid profiles. PCOS, is often accompanied by disturbances in metabolism and lipid levels and incorporating omega-3 supplements into the management of PCOS might offer valuable advantages in these areas.

Lipid Profiles and Omega-3 Fatty Acids 

  • Triglyceride Levels: Elevated triglyceride levels are often observed in individuals with PCOS, increasing the risk of cardiovascular complications. Omega-3 fatty acids, particularly EPA and DHA, have demonstrated the ability to lower triglyceride levels. These fatty acids work by reducing the production of triglycerides in the liver and enhancing their clearance from the bloodstream.
  • HDL Cholesterol: High-Density Lipoprotein (HDL) cholesterol, often referred to as "good" cholesterol, plays a crucial role in cardiovascular health. Low HDL levels are a concern for individuals with PCOS. Omega-3s have been associated with raising HDL cholesterol levels, which can contribute to a healthier lipid profile and reduce the risk of heart disease.
  • Inflammation Control: Chronic inflammation is a common characteristic of PCOS and can contribute to metabolic disturbances. Omega-3 fatty acids are renowned for their anti-inflammatory properties, which can help alleviate the systemic inflammation often seen in individuals with PCOS. By reducing inflammation, omega-3s may further support improved lipid profiles and overall metabolic health.

Incorporating Omega-3 Supplements 

To harness the potential benefits of omega-3 fatty acids for metabolic health and lipid profiles, women with PCOS may consider incorporating omega-3 supplements into their daily routine. These supplements are available in various forms, including fish oil capsules, krill oil, and algae-based supplements (suitable for vegetarians and vegans). However, it's crucial to consult a healthcare professional before starting any supplementation regimen, as they can provide personalised advice based on individual health needs and any potential interactions with other medications or conditions.


Elevated Inflammation in PCOS 

Inflammation is a complex physiological response that plays a vital role in the body's defense against harmful stimuli as well. However, when this response becomes chronic, it can contribute to a range of health issues, including PCOS. In fact, many women with PCOS experience elevated levels of inflammatory markers in their blood.

This inflammation can exacerbate various aspects of PCOS, from irregular menstrual cycles to insulin resistance. It can also contribute to the overproduction of androgens, further complicating the hormonal imbalance at the heart of this condition.

The Role of Omega-3s in Reducing Inflammation 

Omega-3 fatty acids wield a remarkable power—the power to counteract inflammation. These are known to influence the production of inflammatory molecules, mitigating the excessive inflammation that can perpetuate PCOS-related symptoms. By incorporating omega-3s into your dietary or supplement regimen, you might be aiding your body's efforts to maintain a healthier balance between inflammatory and anti-inflammatory responses.
