What are Probiotics and why do we need them?

Probiotics are essentially beneficial bacteria that naturally inhabit our bodies. These microscopic organisms, primarily found in the gut, play a pivotal role in maintaining our overall health. They are integral to the functioning of our digestive system, aiding in the breakdown of food and absorption of nutrients.

Moreover, probiotics are instrumental in keeping harmful bacteria in check, thus preventing their overgrowth and the subsequent health issues that could arise. They also bolster our immune system, ensuring it functions optimally to ward off diseases. In the context of gut health, probiotics assist in maintaining bowel regularity and ensuring proper elimination.

Probiotics and Gut Health

In addition to these fundamental roles, probiotics are crucial in restoring and maintaining balanced gut flora, especially after antibiotic treatments which can indiscriminately kill both harmful and beneficial bacteria.

The intricate relationship between probiotics and gut health is a topic of increasing interest in the scientific community. Probiotics, particularly Lactobacillus acidophilus, play a pivotal role in maintaining the delicate balance of our gut flora. This balance is crucial for optimal health, as the gut is not just a digestive organ, but a complex ecosystem teeming with trillions of microorganisms that interact with each other and our bodies.

The disruption of this gut flora, due to factors such as antibiotic therapy, poor diet, stress, and environmental toxins, can lead to a host of health issues. These include abdominal pain, bloating, gas, constipation, and diarrhoea. By supplementing with probiotics, we can help restore and maintain a healthy gut flora, thereby alleviating these symptoms and promoting overall gut health.

Probiotics and Immune System

The immune system, a complex network of cells, tissues, and organs, is our body's primary defence against harmful invaders. It's a well-known fact that nearly 70% of our immune system is associated with the gastrointestinal (GI) tract. This association is facilitated by the symbiotic relationship between our immune system and the various bacterial colonies, or flora, that reside in our GI tract. These beneficial bacteria play a crucial role in maintaining the health and function of our GI tract, and by extension, our immune system.

As we’ve discussed however, factors such as antibiotic therapy, illness, poor diet, stress, and environmental toxins can disrupt the balance of our gut flora. This imbalance can lead to a weakened immune system, making us more susceptible to diseases. Probiotics, particularly strains like Lactobacillus acidophilus, can help restore and maintain a healthy balance of gut flora. By doing so, they support our immune system, helping it function optimally. Therefore, supplementing with probiotics is not just beneficial for our gut health, but also crucial for a robust immune system.

In the context of diet, probiotics are not limited to yogurt and dairy products. They can be found in a variety of foods such as fermented and unfermented milk, miso, kimchi, tempeh, soy beverages, and even some juices and cereals. For those who prefer a more concentrated source, probiotics are also available in supplement form, such as capsules and powders.

The modern lifestyle, marked by stress, poor diet, and exposure to environmental toxins, coupled with a decline in the consumption of fermented foods, has made the supplementation of probiotics more crucial than ever. This is particularly true for individuals with Polycystic Ovary Syndrome (PCOS), where emerging research is highlighting the potential benefits of probiotics in supporting immune and intestinal health, reducing inflammation, and improving metabolic health.

Benefits of Probiotics for PCOS

The potential benefits of probiotics for PCOS (Polycystic Ovary Syndrome) are increasingly being recognised in the medical community. Recent studies have shown that probiotics, particularly strains of Lactobacillus acidophilus, can have a significant impact on the symptoms and complications associated with this condition. From improving insulin sensitivity, reducing inflammation and overall gut health, the role of probiotics in managing PCOS is becoming more apparent.

In the following sections, we will delve deeper into the specific benefits of probiotics for PCOS, focusing on their effects on insulin sensitivity and inflammation. We will explore the scientific evidence supporting these claims and discuss how incorporating probiotics into your diet could potentially improve your health and quality of life if you are living with PCOS.

Probiotics and Insulin Sensitivity

Probiotics, particularly Lactobacillus acidophilus, have shown promising results in enhancing insulin sensitivity, a common issue in PCOS. A clinical trial involving male volunteers, including those with type 2 diabetes, demonstrated an improvement in insulin sensitivity after a 4-week supplementation with Lactobacillus acidophilus NCFM®. Although the trial was conducted on men, the positive outcome suggests potential benefits for women with PCOS experiencing insulin sensitivity issues.

Moreover, a randomized, double-blind, placebo-controlled trial involving 60 PCOS patients revealed significant reductions in BMI, serum insulin, and blood lipid levels after 12 weeks of probiotic supplementation. The probiotic capsules contained three strains, including Lactobacillus and Bifidobacterium bifidum. These findings further underscore the potential of probiotics for PCOS, particularly in enhancing insulin sensitivity.

Probiotics and Inflammation in PCOS

In the realm of PCOS management, the role of probiotics in mitigating inflammation is gaining significant attention. The inflammatory response in PCOS is often triggered by an imbalance in gut microbiota, leading to an overactive immune response. This, in turn, can exacerbate PCOS symptoms and contribute to the development of insulin resistance.

A study involving Lactobacillus acidophilus, Lactobacillus casei, and Bifidobacterium bifidum supplementation demonstrated a significant reduction in chronic inflammatory states. This was evidenced by decreased levels of serum high-sensitivity C-reactive protein (hs-CRP) and malondialdehyde (MDA) concentrations, both markers of inflammation. The probiotic supplementation not only reduced inflammation but also improved hormonal balance by increasing serum levels of sex hormone-binding globulin (SHBG) and reducing total serum testosterone levels. These findings suggest that probiotics for PCOS could be a promising avenue for managing inflammation and hormonal imbalances associated with the condition.

The Gut Microbiome - Probiotics for digestive Health in PCOS

The gut microbiome, a complex ecosystem of microorganisms residing in our digestive tract, has been a subject of intense research in recent years and plays a crucial role in our overall health, including our metabolic and immune functions. Its role in health and disease is becoming increasingly clear, with studies suggesting a link between gut microbiota and Polycystic Ovary Syndrome (PCOS).

Probiotics, particularly strains of Lactobacillus and Bifidobacterium, have shown promising results in improving gut health and managing PCOS symptoms. These beneficial bacteria can help restore the balance of gut microbiota, which is often disrupted in women with PCOS. This disruption, known as dysbiosis, can lead to increased intestinal permeability and an overactive immune response, potentially exacerbating PCOS symptoms. The theory of Dysbiosis of Gut Microbiota (DOGMA) suggests that an imbalance in the gut flora, possibly due to poor diet, could trigger a chain of events affecting insulin levels, androgen production, and ultimately, ovarian function. This theory, coupled with recent research findings, underscores the potential of probiotics, particularly Lactobacillus acidophilus, in managing PCOS.

The Dysbiosis of Gut Microbiota (DOGMA) theory, was first proposed in a study by Tremellen & Pearce (2012). They suggested that poor diet-induced intestinal dysbiosis could increase intestinal permeability, leading to lipopolysaccharides (LPS) escaping into the body's circulation. LPS, found on the outer layer of gram-negative bacteria, can trigger strong immune responses, potentially leading to a cascade of events affecting insulin levels, androgen production, and consequently, the ovaries.

This theory was further supported by a murine study by Guo et al. (2016), which found that rats with PCOS had lower levels of beneficial bacteria such as Lactobacillus, Ruminococcus, and Clostridium, and higher levels of potentially harmful bacteria like Prevotella. This imbalance was linked to increased levels of androgens and testosterone, key markers of PCOS. Furthermore, when these rats were given faecal microbiota transplants or Lactobacillus transplantation, their hormone levels normalised, and their reproductive cycles improved. This suggests that restoring a healthy gut microbiota could potentially help manage PCOS symptoms.

It's important to note that while these findings are promising, more research is needed to fully understand the complex relationship between the gut microbiota and PCOS. As we continue to unravel the mysteries of the gut microbiome however, it's clear that probiotics could play a significant role in the future of PCOS management.

Food sources of probiotics

Probiotics, the friendly bacteria that bolster health in numerous ways, are not confined to the realm of supplements and capsules. They are naturally present in a variety of foods, offering a delicious and nutritious way to support your health, particularly for those dealing with Polycystic Ovary Syndrome (PCOS). From aiding digestion to supporting the immune system, these beneficial microorganisms are a crucial part of a balanced diet.

Probiotics in Dairy Products

Dairy products, particularly yogurt, are a rich source of probiotics, including the beneficial Lactobacillus acidophilus. These products undergo a fermentation process, which allows the growth of these beneficial bacteria. The probiotics in yogurt are known to assist with digestion, nutrient assimilation, and maintaining bowel health. They also play a crucial role in inhibiting the overgrowth of harmful bacteria, supporting the immune system, and restoring balanced gut flora after antibiotic use.

In addition to yogurt, other dairy products such as fermented and unfermented milk also contain probiotics. These dairy-based probiotics known as Kefir, when consumed regularly, can contribute to improved health outcomes, particularly for individuals with PCOS. Emerging research suggests that these probiotics can help improve cholesterol, insulin, testosterone levels, and inflammation, thereby enhancing fertility. Therefore, incorporating dairy products rich in probiotics into the diet can be a beneficial strategy for managing PCOS.

Probiotics in Fermented Foods

Fermented foods are a treasure trove of probiotics, offering a diverse range of beneficial bacteria. Kimchi, a Korean staple, is a prime example. This spicy, fermented cabbage dish is teeming with Lactobacillus acidophilus and other probiotics, making it a potent ally for those battling PCOS.

Another fermented food rich in probiotics is tempeh. Originating from Indonesia, this soy-based product undergoes a fermentation process that enhances its probiotic content. Consuming tempeh can help replenish the gut flora, potentially improving PCOS symptoms. These fermented foods, along with others, offer a natural, dietary approach to harnessing the power of probiotics.

Efficacy And Safety Of Probiotics

The efficacy and safety of probiotics, particularly for women with PCOS, have been substantiated by numerous scientific studies. Probiotic supplementation, including strains such as Lactobacillus acidophilus, has been shown to offer significant health benefits. These include a reduction in BMI, lower serum insulin, and improved blood lipid levels. Furthermore, probiotics have been found to increase serum levels of sex hormone-binding globulin (SHBG), reduce total serum testosterone levels, and improve chronic inflammatory states.

The safety of probiotics is also well-established, with minimal side effects reported. However, it's crucial to note that not all probiotics are created equal. The dose needed for probiotics varies greatly depending on the product and strain. Therefore, when selecting a probiotic, it's advisable to choose a product that contains the same strain used in clinical studies. This ensures the efficacy and safety of the probiotic, particularly for women with PCOS.


The emerging research on probiotics, particularly Lactobacillus acidophilus, and their potential benefits for PCOS is promising. Probiotics have been shown to improve various aspects of PCOS, including cholesterol, insulin, testosterone, inflammation, and fertility. They also support the immune system, intestinal health, and metabolic health, which are crucial for managing PCOS.

Clinical trials have demonstrated the efficacy and safety of probiotics, with no adverse effects observed. However, it's important to note that not all probiotics are created equal. The strain and dosage matter, and it's recommended to choose a product that contains the same strain used in clinical studies. The MHRA in the UK recognises probiotics as generally safe, but more research is needed to fully understand their potential, including the appropriate dosage and safety for women with PCOS.

In conclusion, probiotics, especially Lactobacillus acidophilus, offer numerous health benefits for individuals with PCOS.
