Omega-3 fatty acids can help manage PCOS by addressing hormonal imbalances, inflammation, and insulin resistance. These essential fats, found in fatty fish like salmon and mackerel or supplements, improve metabolic health, lower androgen levels, and support fertility. Research shows that omega-3s reduce testosterone, improve menstrual regularity, and enhance glucose control. For best results, pair omega-3 intake with a healthy diet and exercise. Consult a healthcare provider to determine the right dosage for your needs and consider supplements with EPA and DHA for maximum benefits.

How Omega-3s Affect Hormonal Balance
Omega-3 fatty acids play a key role in managing PCOS by targeting inflammation, reducing androgen production, and improving metabolic function. Unlike treatments that focus solely on symptoms, omega-3s address several underlying factors contributing to PCOS.
Lowering Inflammation and Androgen Levels
Chronic inflammation is a significant factor in many PCOS symptoms. Omega-3s help counteract this by reducing inflammatory activity in the body. They displace inflammatory compounds in cell membranes and lower arachidonic acid (AA), a substance involved in androgen production. EPA and DHA, found in fish oil, directly compete with AA for space in cell membranes, while ALA from plant sources influences the enzymes that process AA.
Studies back these effects. For instance, women with the highest omega-3 levels in their blood were 40% less likely to have PCOS compared to those with the lowest levels. Another study showed that taking 2.4 grams of EPA and DHA daily for six weeks significantly reduced bioavailable testosterone levels in women with PCOS. Omega-3s also increase SHBG (sex hormone-binding globulin), which reduces free androgens, alleviating symptoms like acne and excessive hair growth.
Additionally, omega-3s lower key inflammatory markers, such as high-sensitivity C-reactive protein (hs-CRP), and increase adiponectin, a hormone that supports metabolism. These combined effects not only reduce androgen levels but also improve insulin sensitivity, creating a ripple effect of benefits.
Improving Insulin Sensitivity
Insulin resistance is a core issue in PCOS, often triggering further hormonal imbalances. Omega-3 fatty acids have been shown to improve insulin sensitivity through multiple mechanisms. In a study involving 185 women with PCOS, higher intake of long-chain omega-3s was linked to lower HOMA-IR values (a measure of insulin resistance), while higher blood levels of omega-3s, EPA, and DHA were associated with reduced insulin resistance [undefined].
At a cellular level, omega-3s enhance insulin signaling by upregulating GLUT4, IRS1, and GYS1 - key components of glucose metabolism. DHA also interacts with SIRT1, a protein that helps regulate glucose levels and reduce mitochondrial dysfunction, which is a known contributor to insulin resistance. These improvements translate into better glucose management, addressing one of the primary drivers of PCOS-related complications.
Effects on Metabolism
Omega-3s also support broader metabolic health, which is particularly beneficial for women with PCOS. One notable effect is their ability to lower triglyceride levels. A meta-analysis of nine randomized controlled trials involving 591 women found that omega-3 supplementation reduced triglycerides by an average of 29.21 mg/dL and improved overall cholesterol levels [undefined].
Another benefit is the boost in adiponectin, a hormone that enhances insulin sensitivity, reduces inflammation, and aids in fat metabolism. This extends to liver health as well. Research using proton magnetic resonance spectroscopy showed that omega-3 supplementation reduced liver fat in women with PCOS.
EPA and DHA from fish oil are especially effective because they integrate directly into cell membranes, offering benefits that plant-based ALA cannot match [undefined].
Research Studies on Omega-3s and PCOS
Recent research highlights the potential of omega-3 fatty acids in improving key health markers for women with PCOS. Studies consistently show benefits in areas like insulin resistance, hormonal balance, and menstrual cycle regulation.
Improvements in Insulin Sensitivity
Omega-3 supplementation has been shown to boost insulin sensitivity in women with PCOS. A meta-analysis of nine randomized controlled trials found that omega-3 polyunsaturated fatty acids (PUFAs) significantly reduced HOMA-IR, a primary indicator of insulin resistance. Another analysis of 11 trials echoed these findings, reporting not only better HOMA-IR scores but also increased levels of adiponectin, a hormone that enhances insulin sensitivity. The benefits appear most pronounced after at least eight weeks of supplementation, likely because omega-3s need time to integrate into cell membranes to fully exert their effects.
In a cross-sectional study of 185 women with PCOS, researchers observed an inverse relationship between omega-3 intake and serum insulin levels. Women consuming more long-chain omega-3 PUFAs, particularly those derived from marine sources like EPA and DHA, exhibited better glucose control and lower insulin resistance compared to those consuming plant-based alpha-linolenic acid (ALA). These metabolic improvements also contribute to better hormonal regulation.
Reduced Androgen Levels
Omega-3s also play a role in lowering androgen levels, which are often elevated in women with PCOS. A meta-analysis of ten randomized controlled trials demonstrated that omega-3 supplementation reduces serum total testosterone levels and increases SHBG (sex hormone-binding globulin). This effect may stem from omega-3s' ability to reduce arachidonic acid, a precursor in LH-stimulated steroid production. Fish oil, rich in EPA and DHA, has been found to be more effective in this regard than flaxseed oil, which contains primarily ALA.
Population studies further support these findings. Women with the highest levels of serum phospholipid omega-3 PUFAs were found to be 40% less likely to have PCOS compared to those with the lowest levels. These hormonal shifts are linked to improved menstrual cycles and ovulation.
Benefits for Menstrual Regularity and Ovulation
Omega-3 supplementation has been shown to restore menstrual regularity and improve reproductive outcomes. In a randomized clinical trial conducted in Yazd, Iran, 78 overweight and obese women with PCOS received either 3 grams of omega-3 or a placebo daily for eight weeks. The results were striking: 47.2% of women in the omega-3 group experienced menstrual regularity, compared to just 22.9% in the placebo group (p = 0.049).
"In summary, 8 weeks supplementation with 3gr of omega-3 could reduce serum concentrations of testosterone in overweight and obese PCOS patients. In addition, menstrual cycle becomes more regular in this group of subjects." – Azadeh Nadjarzadeh et al.
Further evidence comes from a randomized, double-blind study showing that clinical pregnancies occurred in 26.7% of treatment cycles for women taking omega-3 supplements, compared to only 13.3% in the placebo group. Among overweight and obese women (BMI 25–35), the difference was even more pronounced: 29.6% of cycles in the omega-3 group resulted in pregnancy, compared to just 5.3% in the placebo group (P < 0.04). Meta-analyses also suggest that incorporating omega-3s into the diet can enhance pregnancy rates and menstrual regularity, addressing a core reproductive challenge for women with PCOS.

Omega-3s for Skin and Hair Problems in PCOS
Omega-3 fatty acids, already known for their metabolic benefits, also play a role in addressing skin and hair problems associated with PCOS. These issues, which can significantly impact daily life, are common among women with PCOS. In fact, nearly 75% of women with the condition deal with excessive hair growth, while many also face challenges like acne and hair thinning or loss.
Treating Acne and Inflammation
Omega-3s have been shown to reduce acne severity in women with PCOS by targeting the inflammation that contributes to breakouts.
"Omega-3 fatty acids (ω-3 FAs) exert anti-inflammatory effects, including the downregulation of pro-inflammatory cytokines, eicosanoids, and insulin-like growth factor-1. Therefore, they may improve acne severity as an adjunct treatment."
These fatty acids promote the production of anti-inflammatory compounds like prostaglandin E1 (PGE1), prostaglandin E3 (PGE3), and leukotriene B5 (LTB5), helping to calm the skin. A randomized controlled trial found that taking 2,000 mg of omega-3s daily led to significant acne reduction after just 10 weeks. Dr. Jolene Brighten, a specialist in women's hormonal health, highlights:
"Omega-3 fatty acids have been shown to be beneficial to skin health and assist in clearing acne"
Additionally, omega-3s lower insulin-like growth factor-1, a key driver of acne, further contributing to clearer skin.
Managing Unwanted Hair Growth and Hair Loss
Omega-3s are also helpful in tackling hair-related problems caused by PCOS, such as excessive hair growth (hirsutism) and hair thinning or loss. Elevated androgen levels, particularly DHT, can shrink hair follicles and disrupt the hair growth cycle. Insulin resistance and chronic inflammation, both hallmarks of PCOS, further complicate healthy hair development.
Omega-3 supplementation helps by reducing testosterone levels, and some studies suggest these fatty acids may lower androgen levels in women with PCOS. For more targeted treatments, Oana Health offers solutions like oral minoxidil for hair regrowth, topical spironolactone for thinning hair, and eflornithine to manage unwanted facial hair.
To naturally increase omega-3 intake, include two servings of oily fish - such as salmon, mackerel, sardines, or anchovies - in your weekly diet. If dietary sources are insufficient, fish oil or algae-based omega-3 supplements are excellent alternatives.
Research Gaps and Limitations
While there’s strong evidence supporting omega-3s' benefits for PCOS-related metabolic issues, research directly focusing on their effects on skin and hair remains limited. Most studies emphasize improvements in insulin sensitivity and testosterone levels, with skin and hair benefits often observed as secondary outcomes. More research is needed to determine the long-term effects and ideal supplementation strategies for managing acne, hirsutism, and hair loss in women with PCOS. Though many experts recommend omega-3s as part of a PCOS treatment plan, further studies are essential to fully understand their potential.
Adding Omega-3s to Your PCOS Treatment Plan
Managing PCOS isn’t about a single solution - it’s about weaving together multiple strategies to tackle this complex condition. Omega-3 fatty acids are a valuable piece of the puzzle, but they work best when combined with a comprehensive treatment plan.
Pairing Omega-3s with Lifestyle Adjustments
Omega-3 supplements shine brightest when paired with lifestyle changes. Experts recommend that all women with PCOS incorporate diet and exercise into their routine. Adding omega-3s to these changes can amplify their benefits.
Diets like the Mediterranean, DASH, and low-glycemic index plans focus on improving nutrient quality and metabolic health rather than just weight loss. Studies show that omega-3s can enhance these diets by improving metabolic markers. For example, a meta-analysis found that omega-3 PUFA reduced HOMA-IR (a measure of insulin resistance), total cholesterol, and triglycerides. Another study revealed similar results, particularly in trials lasting over eight weeks, with improvements in HOMA-IR, triglycerides, cholesterol, and adiponectin.
Physical activity also plays a crucial role. Regular exercise boosts the positive effects of omega-3s on insulin sensitivity and hormone regulation. By building on these lifestyle foundations, you can create a more tailored and effective PCOS management plan.

Along with personalized treatments, choosing the right omega-3 supplement is key to achieving the best results.
Choosing the Best Omega-3 Supplement
When picking an omega-3 supplement, focus on dosage, type, and quality. Aim for a daily dose of 1,000–2,000 mg of combined EPA and DHA. Look for marine-derived options that have been independently tested for purity, and take them with a meal containing fat for better absorption.
The type of omega-3 you choose matters. Fish oil (rich in EPA and DHA) is more effective at reducing serum testosterone in women with PCOS compared to ALA-based options like flaxseed oil. EPA is especially good at reducing inflammation, while DHA supports brain health. Together, they provide well-rounded support for PCOS.
Check for supplements that include a Certificate of Analysis and have undergone independent purity testing. Also, ensure the product is fresh - rancid fish oil can cause digestive discomfort and lose its effectiveness. Opt for a highly absorbable or bioavailable supplement.
Angela Grassi, MS, RDN, LDN, from The PCOS Nutrition Center, highlights the benefits of omega-3s:
"Omega 3 fats are effective at improving many aspects of PCOS including triglycerides and mood, and help to support a healthy pregnancy."
Before starting omega-3 supplementation, especially in higher doses, consult your healthcare provider - particularly if you’re on blood thinners or blood pressure medication. This step ensures your omega-3 routine complements your overall treatment plan safely.
Omega-3s as Support for PCOS Management
Omega-3 fatty acids play a key role in managing PCOS by improving insulin sensitivity, lowering elevated androgen levels, and reducing inflammation. These fats tackle multiple challenges by decreasing inflammation and increasing adiponectin secretion. This combination helps the body use insulin more efficiently and improves lipid profiles by reducing triglycerides and total cholesterol.
Research indicates that women with higher omega-3 levels in their blood have a 40% lower risk of developing PCOS. Additionally, supplementation has been shown to lower total testosterone and increase SHBG (sex hormone-binding globulin), helping to address symptoms like acne, unwanted hair growth, and irregular menstrual cycles.
Omega-3s also help regulate immune responses, addressing the chronic inflammation often associated with PCOS. Including these benefits as part of a broader, tailored treatment plan can make a significant difference in managing the condition.
For effective results, experts recommend a daily intake of 1,000–4,000 mg of combined EPA and DHA omega-3s. Fish oil supplements, which contain these marine-based omega-3s, are more effective at reducing testosterone levels compared to plant-based options like flaxseed oil. Taking these supplements with meals not only boosts absorption but also helps reduce potential digestive discomfort.
Platforms like Oana Health incorporate omega-3 supplementation into targeted treatments for PCOS. These treatments address insulin resistance, hormonal imbalances, and symptoms such as hair growth or hair loss, offering a convenient telehealth approach to personalized care. Omega-3s stand out as a valuable component in managing PCOS effectively.
FAQs
How do omega-3 fatty acids help improve insulin sensitivity in women with PCOS?
Omega-3 fatty acids play a key role in improving insulin sensitivity for women dealing with PCOS. They work by tackling inflammation and enhancing the way the body handles fats. Specifically, omega-3s help lower inflammatory markers like TNF-α and IL-6, both of which are linked to insulin resistance.
Beyond reducing inflammation, omega-3s also encourage fatty acid oxidation and curb fat production in the liver. This results in a healthier lipid profile, which is crucial for metabolic health. By addressing these factors, omega-3s help the body manage insulin more effectively, offering significant benefits for women with PCOS.
What are the best sources of omega-3s for managing PCOS, and should you rely on food or supplements?
For women navigating PCOS, incorporating fatty fish like salmon, mackerel, tuna, and trout into your diet can be incredibly beneficial. These fish are packed with EPA and DHA, the most effective forms of omega-3s for helping lower testosterone levels and boosting insulin sensitivity. While these are the top sources, plant-based options such as walnuts, chia seeds, flaxseeds, and leafy greens also offer omega-3s in the form of ALA. Though ALA is less potent than EPA and DHA, it still plays a helpful role when included in a well-rounded diet.
If it’s tough to get enough omega-3s through food alone, supplements like fish oil or algae-based products can fill the gap. Fish oil, in particular, is a powerhouse for hormonal balance, delivering higher concentrations of EPA and DHA compared to plant-based ALA sources. However, before adding any supplement to your routine, it’s essential to check in with a healthcare provider to make sure it’s the right fit for you.
What should I know about potential side effects of omega-3 supplements when managing PCOS?
While omega-3 supplements can help manage hormonal balance for women with PCOS, they may come with some minor side effects. Common issues include fishy burps, heartburn, or nausea. These can often be minimized by taking the supplements with meals or freezing the capsules before use.
At higher doses, omega-3s might thin the blood, potentially increasing bleeding risks - especially for individuals on blood-thinning medications. To stay safe, it's always a good idea to consult a healthcare professional before starting omega-3 supplements. They can help determine the right dosage and assess any potential interactions with other medications or health conditions.
