PCOS isn't just about one hormone — it's a whole-body picture. Nutrients like myo-inositol, vitamin D, omega-3s, folate, B12 and zinc can support insulin signalling, hormone balance and inflammation, while fibre and balanced meals help keep cravings and energy swings in check.

The foundation for a happy gut, stable energy, and long-term heart health

Fibre is the unsung hero of nutrition. Think of it as the ultimate caretaker for your digestive system -
            it helps keep everything running smoothly and nourishes the good bacteria in your gut, which is essential for overall wellness. 
            A fibre-rich intake helps you feel full for longer, keeps your energy levels stable, and plays a key role in supporting long-term heart health.

Fibre

The British Nutrition Foundation explains the UK's 30g daily goal for digestive wellness and long-term health, offering practical tips to help you increase your intake.

There is a 10% reduction in all-cause mortality for each 10g/day increase in fibre intake

Most US adults only get half the fiber they need, but it can lower risk of heart disease, diabetes and some cancers.

Vital fuel for brain health, hormone balance, and absorbing key vitamins

Healthy fats are essential fuel for your body and brain. They help you absorb key vitamins and play a vital role in keeping your systems in harmony.
         The key is to focus on getting more unsaturated fats from whole and non-processed food — the kind found in avocados, nuts, seeds, and olive oil. These are the fats that truly nourish your body, 
        helping to support long-term heart health and keep you feeling your best.

Healthy Fats

A simple switch from saturated to unsaturated fats is a powerful way to help lower cholesterol and support a healthy heart.

Unsaturated fats are considered 'good fats', saturated fats are considered 'bad fats, trans fats are the 'worst' dietary fat.

Strong evidence shows that replacing saturated fats with healthier unsaturated fats can significantly reduce the risk of heart disease.

The sunshine vitamin for healthy bones, teeth and muscles

Often called the 'sunshine vitamin', Vitamin D is unique because your body creates it from sunlight. 
        It's essential for guiding calcium to where it's needed most, helping to keep your bones and muscles strong and healthy.

        During the darker autumn and winter months, or if you don't get much time outdoors, it can be tricky to get enough. That's when turning to food sources like oily fish, eggs, and fortified foods becomes a great way to top up your levels. For many, a simple daily supplement during these months is also a wise choice.

The fundamental nutrient for building new cells and supporting healthy development

Vitamin B9, or Folate, plays a fundamental role in building and repairing your body. It is essential for creating new cells and forming DNA—the blueprint for all cell growth and function.

This role becomes especially critical during periods of rapid growth, which is why Folate is so important for a healthy pregnancy. For this reason, a folic acid supplement (the synthetic form of folate) is strongly recommended for women who are planning a pregnancy or are in the early stages.

Like other B vitamins, Folate is water-soluble, meaning your body can't store large amounts. A consistent intake of folate-rich foods is key to keeping your cellular repair and renewal systems well-supplied.

Helps make red blood cells and keeps the brain and nervous system healthy.

Vitamin B12, also known as Cobalamin, is vital for several key bodily processes. It's a primary component in the formation of healthy red blood cells, which are responsible for carrying oxygen to every part of your body. It also plays a crucial role in protecting your nerve cells and supporting the fundamental process of DNA creation.

        A unique aspect of B12 is its source. It is found almost exclusively in animal-derived foods like meat, fish, eggs, and dairy. This makes it a crucial nutrient for those following a vegan or strictly vegetarian diet to be mindful of. Fortified foods (like some plant milks and cereals) or a reliable supplement are the best ways to ensure an adequate intake.
        
        Unlike many other B vitamins, your body can store B12 in the liver for several years. This means a deficiency can take a long time to develop, making a consistent, long-term source all the more important.

A key mineral for a strong immune system and your body's natural repair process

Zinc is a fundamental mineral involved in the work of over 300 enzymes in your body. This vast range of activity is essential for supporting a robust immune system, healing wounds, and even maintaining your senses of taste and smell.

        While zinc is present in many foods, how your body absorbs it can differ. Animal sources like meat and shellfish provide zinc that is easily used by the body. Plant-based sources like legumes, nuts, and seeds are also excellent, but their zinc can be slightly less available for absorption due to naturally occurring compounds in the plants.

Long-chain omega-3 from fish; vital for brain and anti-inflammatory effects

While plant-based ALA is the starting point, EPA and DHA are the powerful, ready-to-use forms of omega-3, found almost exclusively in oily fish and other marine sources. They are vital for brain function and vision, and play a key role in helping to regulate your body's inflammatory response.

        Instead of a strict daily milligram target, the simplest and most effective strategy is to aim for two portions of fish per week, ensuring at least one of them is oily. For those who don't eat fish, a quality supplement providing around 450mg of combined EPA and DHA daily is an effective alternative.

Omega-3 (LC)

The British Heart Foundation advises eating two portions (= 140g each) of fish per week, one of which is oily, providing about 450 mg EPA + DHA per day.

The NIH provides more guidance on long-chain omega-3, for which there is no universally agreed RDA

The NHS outlines the importance of fish in our diet, but notes that some oily fish are high in pollutants and should be eaten in moderation.

A powerful antioxidant that fuels cellular energy and supports heart and fertility health

Coenzyme Q10 (CoQ10) is a key part of your cells' energy machinery.
    It sits inside mitochondria – the “power stations” of your cells – and helps create ATP, the main energy currency your body uses. CoQ10 also acts as an antioxidant, helping to protect cell membranes and delicate structures like sperm cells from oxidative stress.

    Your body can make CoQ10, and it is found in small amounts in foods like meat and fish, but levels may fall with age or certain medications. That's why CoQ10 is often studied in the context of heart health, fatigue, and male fertility.

Supports insulin signalling, hormone balance, and PCOS management

Myo-inositol is a vitamin-like compound that your body uses as part of its internal signalling system.
    It plays a key role in how cells respond to insulin and other hormones, which is why it has become an important focus in supporting conditions linked to insulin resistance, such as PCOS.

    Although small amounts are made in the body and found in foods like fruits, beans, and whole grains, higher intakes are often studied in supplement form when targeting hormone and cycle-related symptoms.
