Omega-3: How it can help with PCOS

Omega-3 for PCOS: What you should know

People with polycystic ovary syndrome (PCOS) may have heard that omega-3 fatty acids can play a supportive role in PCOS . They may help the immune system reduce low-grade inflammation. This can also improve the balance of male hormones, which can have positive effects on PCOS symptoms such as acne and hair loss.


In this article you will learn why Omega-3 can support general well-being in PCOS , what indications there might be of benefits for typical PCOS symptoms, and what should be taken into account when taking it.

What are Omega-3 fatty acids?

Omega-3 fatty acids are polyunsaturated fatty acids that the body cannot produce itself and therefore must be obtained through diet . They are essential for the proper functioning of our cell membranes and support the work of nerve cells.

Omega-3 fatty acids are particularly important during pregnancy, as they promote the child's brain development. They are also essential for adults, as they help regulate inflammation in the body, lower blood pressure, and reduce the risk of cardiovascular disease.


There are three important omega-3 fatty acids:


  • Alpha-linolenic acid (ALA): This plant-based omega-3 fatty acid is found in foods such as flaxseed, flaxseed oil, walnuts, rapeseed oil and hemp oil.
  • Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA): These long-chain omega-3 fatty acids are found primarily in fatty cold-water fish such as salmon, herring, mackerel, and anchovies. EPA and DHA are particularly important for inflammatory metabolism and the function of nerve tissue, including the optic nerve and retina.

Why are omega-3 fatty acids important for PCOS?

  • Omega-3 fatty acids can be a valuable supplement for women with PCOS, as they are said to support various bodily functions.
    • Supporting mental well-being : Omega-3 fatty acids are said to reduce depressive symptoms and anxiety, which may be beneficial for women with PCOS who have a higher risk of mental stress.
    • Anti-inflammatory effect : Omega-3 fatty acids have been shown to contribute to the reduction of inflammation in the body. Since low-grade inflammation is often associated with PCOS, taking omega-3 may have a positive effect on these processes.
    • Improved insulin sensitivity : Omega-3 can improve insulin sensitivity, which is beneficial in PCOS, as insulin resistance is a common symptom of the disease.
    • Hormone regulation : There is evidence that omega-3 fatty acids may help regulate male hormones, which could have a positive effect on PCOS symptoms such as acne and hair loss.
    • Skin support : Omega-3 can help improve skin problems such as acne, which are often associated with inflammation in the body.

It is important to point out that Omega-3 is not a cure for PCOS , but can play a supportive role in managing symptoms.

Symptoms of an Omega-3 deficiency

Symptoms of an omega-3 deficiency can manifest in various ways in the body, as these essential fatty acids play a vital role in numerous biological processes. Here are some potential signs of a deficiency that could be exacerbated by insufficient omega-3 levels.


  • Dry skin : Omega-3 fatty acids support the skin barrier and moisture regulation. A deficiency can potentially lead to dry, cracked, or flaky skin.

  • Skin problems : There is evidence that an omega-3 deficiency could worsen inflammatory skin conditions such as acne or eczema.

  • Hair loss and brittle hair : A deficiency in Omega-3 could lead to thinner and more brittle hair.

  • Concentration difficulties : Since omega-3 fatty acids play a role in brain function, a deficiency could manifest as concentration problems or mental exhaustion.

  • Mood swings and depressive moods : There is evidence that an omega-3 deficiency could worsen depressive symptoms or mood swings, as these fatty acids may play a role in regulating mood.

  • Weak immune system : A deficiency in Omega-3 could impair the function of the immune system and promote an increased susceptibility to infections.

  • Slowed wound healing : An insufficient intake of Omega-3 could lead to slowed wound healing.

  • Dry eyes : Omega-3 may contribute to the normal function of the eyes, and a deficiency could lead to dry eyes or eye irritation.

  • Joint problems : Since Omega-3 can have an anti-inflammatory effect, a deficiency could contribute to increased joint pain or stiffness.

Omega-3-rich foods

To ensure sufficient intake of omega-3 fatty acids, it is recommended to regularly eat fatty cold-water fish. The following fish species are particularly rich in omega-3:

  • Farmed salmon: 2,648 mg EPA and DHA per 100 g
  • Herring: 2,014 mg EPA and DHA per 100 g
  • Mackerel: 1,203 mg EPA and DHA per 100 g
  • Salmon (wild): 1,043 mg EPA and DHA per 100 g

For people who follow a vegetarian or vegan diet, plant-based sources such as flaxseed oil, walnut oil, or algae oil are good options. Algae oil is an excellent vegan source of EPA and DHA.

Omega-3 as a dietary supplement

If it is difficult to obtain Omega-3 through food, dietary supplements can be a useful addition .


Omega-3 capsules made from fish or algae oil contain the important fatty acids EPA and DHA and are often specifically tailored to the body's needs.


It is recommended to seek the advice of a doctor or pharmacist before taking dietary supplements to ensure that they are ideally suited to your personal needs .

Omega-3 can be a valuable aid in naturally alleviating PCOS symptoms . There is evidence that it can not only support hormonal balance but also have a positive effect on skin, hair, and mental well-being. To reap these benefits, it's important to regularly consume omega-3 -rich foods or use high-quality supplements.
