For many with PCOS, fertility is such a heartbreaking issue. But while you may have been advised you “can’t have babies,” this is, for the vast majority, simply not true. Getting pregnant with PCOS is possible, and with the right approaches, it may be simpler than you may imagine.
Today, I had a chat with Carlyn Rosenblum, RD, a fertility nutritionist at Trellis, about what they do, what they recommend, and how it can boost your fertility…
What do you do at Trellis?
Your reproductive health is an extension of your overall health. At Trellis, we believe that you need to take care of yourself both physically and mentally in order to foster a healthy environment for conception. That’s where I come in! I help women optimise their nutrition and lifestyle to support their reproductive health, and also manage the side effects and symptoms associated with the egg freezing process.
How does your work support women with PCOS?
I help women understand the connection between their current diet and lifestyle habits and the symptoms they are experiencing. Together, we create a plan that addresses the underlying cause of their discomfort to improve their symptoms and reproductive health.
Why do you incorporate lifestyle and nutritional approaches for PCOS when so many fertility clinics do not?
PCOS is a multifaceted disorder, and therefore effective management of PCOS requires that we not only treat the symptoms but address the root causes of the disorder, such as insulin resistance, food intolerance, gut imbalance, environmental toxin exposure, and high stress – all of which are directly related to diet and lifestyle. While many things are outside of our control, food is a powerful tool that IS within our control, therefore it should be a major focus of PCOS management.![]()

What food and lifestyle choices do you recommend for women with PCOS to boost their fertility naturally, and why?
With PCOS clients, we focus first on nutrition to support blood sugar balance. This generally means implementing an anti-inflammatory, low-glycaemic diet that is rich in vegetables, antioxidant-rich fruits, lean protein, omega-3 healthy fats, and high-fibre carbohydrates, such as legumes and whole grains.
We identify and eliminate food triggers that may cause inflammation in the body; with many PCOS patients, gluten, dairy, caffeine, and alcohol are major trigger foods.
We focus on making fat our friend: This means including 1-2 tbsp of healthy fat at each meal; Avoiding vegetable oils like canola oil, sunflower oil, safflower oil, grapeseed oil, and focusing on olive oil, coconut oil, grass-fed ghee, tahini, nuts, seeds, avocado, etc.
Adding anti-inflammatory foods and spices, such as ginger, garlic, cinnamon, turmeric, and dark leafy greens and vegetables like broccoli, cauliflower, cabbage, and Brussels sprouts.
Adding fermented foods to support gut health, like kimchee, sauerkraut, yogurt, and Kiefer or coconut yogurt.
Supplements can also be effective in supporting PCOS management; while everyone is slightly different in their needs research shows Inositol, CoQ10, L-Carnitine, and adaptogens (among others), can be very effective in PCOS management.
However, my general rule of thumb is food first. You can’t supplement your way out of a bad diet. Even if you are diligent about taking supplements every day, if you continue to eat pizza and ice cream, you won’t see any improvement.

Is there any other advice you’d love to share with women with PCOS?
Improve your diet
This can make a huge difference when it comes to managing your symptoms and improving your fertility. Even something as small as a 5% weight loss is efficacious in improving metabolic parameters and reproductive outcomes.
Switching to a more plant-based diet can have a positive impact on weight and fertility. Research shows that people who follow a plant-based diet have lower BMIs and a lower incidence of infertility than their meat-eating counterparts. The exceptions are eggs, organic whole-fat dairy products, and fish, which have been found to support fertility.
Check your environment
We encounter hundreds of chemicals every day. From air pollutants to cosmetics and household cleaning supplies. Many of these products contain endocrine-disrupting ingredients, such as parabens, sulphates, pesticides, phthalates, and BPA.
Obviously, we can’t control for everything, but try to start by cleaning up your personal hygiene, cosmetics, and household cleaning products. Always buy grass-fed meat, dairy, and organic poultry and eggs. Stick to organic fruits and vegetables as much as possible, especially those on the Dirty Dozen list. See the Environmental Working Group’s 2018 list for more information about this.
