Vegetarian or vegan with PCOS: how to adapt your diet safely

Can you really be vegetarian or vegan if you have PCOS?
This is a question we hear often in the SOVA community. Many women living with PCOS want to reduce animal proteins—for ethical, environmental, or simply personal reasons—but feel torn between their convictions and their health.

If that’s you, you’re not alone. The good news? A vegetarian (or even vegan) diet can work with PCOS—as long as it’s balanced and carefully planned. In this guide, we’ll walk you through the essentials: the benefits, the risks, and the practical tips to make it easier.

What is PCOS, in case you’re new here?

Irregular cycles, acne, unexpected weight gain? You’re not imagining it. PCOS (polycystic ovary syndrome) is a hormonal imbalance that affects about 1 in 7 women. It can show up as acne, hair loss, excess hair growth, irregular or absent periods, and sometimes weight gain linked to insulin resistance.

Vegetarian, Vegan, Flexitarian… what’s the difference?

Quick recap of the main dietary patterns:

• Ovo-lacto vegetarian: no meat or fish, but eggs + dairy allowed.

• Lacto-vegetarian: no meat, fish, or eggs, but dairy allowed.

• Ovo-vegetarian: no meat, fish, or dairy, but eggs allowed.

• Pesco-vegetarian: no meat, but fish allowed.

• Vegan: excludes all animal products (food, honey, even clothing).

• Flexitarian: occasional meat or fish, but mostly plant-based.

Science Check: PCOS & Vegetarian Diets

A well-planned vegetarian diet can help with:

• Cardiovascular health → lower cholesterol & blood pressure.

• Reducing inflammation → which is key, since PCOS is often linked to low-grade inflammation.

• Weight management → more fibre, fewer calories.

• Better blood sugar control → thanks to high-fibre carbs like lentils, quinoa, and chickpeas.

👉 Tip: Many women in our community notice fewer cravings and more stable energy when they combine a vegetarian diet with our Balance Bundle (Ovastart + Sugar Balance). It helps regulate hormones and stabilise blood sugar.

⚠️ Risks: If not managed well, vegetarian or vegan diets can increase the risk of protein and micronutrient deficiencies (iron, B12, zinc, iodine, vitamin D, omega-3s).

Proteins: The Non-Negotiable for PCOS

Proteins are your allies. They regulate blood sugar, support hormonal balance, maintain muscle, and strengthen hair/skin/nails.

Plant-based protein sources to mix & match:

• Legumes: lentils, chickpeas, kidney beans.

• Grains: quinoa, brown rice, oats.

• Soy products: tofu, tempeh, edamame.

• Nuts & seeds: almonds, chia, hemp seeds.

💡 Combine legumes + grains in the same day for a complete amino acid profile.

👉 Not sure if your protein intake is enough? Our Ovastart complex supports hormonal balance and can complement your diet naturally.

Carbs, Omega-3s, and Micronutrients

• Carbs: prioritise whole grains & legumes. Avoid spikes in blood sugar by pairing carbs with proteins and veggies.

• Omega-3s: essential for hormonal balance and inflammation. Vegetarian diets can make it tricky to get enough, since the richest sources are oily fish (mackerel, sardines, salmon, etc.). If you’re pescatarian, our Omega-3 EPAX® formula (made from high-quality fish oil, with a very low ToTox index) can be a great option. But note: it’s not suitable if you’re strictly vegetarian or vegan.

• Plant-based omega-3s: if you don’t eat fish, focus on flax, chia, walnuts, hemp, and rapeseed oil. They provide ALA (a precursor to EPA/DHA, though conversion is limited).

Practical Tips if You’re Vegetarian + PCOS

• Build balanced plates: carbs + proteins + veggies + healthy fats.

• Spice it up: turmeric, ginger, and cinnamon all help reduce inflammation.

• Support digestion: soak and cook legumes well, or blend them into hummus.

• Supplement smartly (especially vitamin B12 & omega-3s).

• Check in with your doctor or dietitian for regular blood work.

Key Takeaway

Yes—you can be vegetarian (or vegan) and still manage your PCOS. But it requires extra attention to protein and micronutrients. Don’t feel like you have to choose between your values and your health—you can have both.
