Overview
Top Medical Research Studies
The study revealed that higher levels of omega-3 PUFAs were linked to lower risks of developing anxiety and depressive disorders, alongside improvement in adverse psychological symptoms.
Additionally, the research highlighted significant associations between these fatty acids and brain white matter structure, providing valuable insights into how omega-3s might support mental wellness.
Our findings indicated that the obese mother rats exhibited higher weight and fat levels and their milk contained less beneficial DHA but more corticosterone and leptin. Notably, their offspring showed a higher ratio of omega-6 to omega-3 fatty acids in the milk they consumed, which correlates to increased anxiety levels, especially in female pups. In contrast, those mothers who received DHA supplements had lower body weight and fat and produced milk with higher DHA content. Their offspring not only had a better balance of omega-6 to omega-3 fatty acids but also demonstrated reduced anxiety compared to those from mothers without supplementation.
Overall, this study highlights the significant positive impact of DHA supplementation during pregnancy and lactation in obese rats, as it not only improves the nutritional quality of their milk but also helps decrease anxiety levels in the offspring in a sex-dependent manner.

To see if EPA could help, we administered fish oil enriched with equal amounts of EPA and DHA for the last five weeks of the study. The results were quite promising. Mice that received the fish oil not only showed reduced anxiety behaviors but also demonstrated improved metabolic health.
Specifically, these mice had better glucose tolerance and reduced food intake, indicating that fish oil could potentially correct some of the metabolic issues that come with obesity. Overall, the addition of EPA-rich fish oil appears to lessen both anxiety and metabolic disturbances caused by a saturated high-fat diet, suggesting its potential benefits for mood and health in similar conditions.
Our findings revealed that when these stressed rats were given a prolonged diet enriched with eicosapentaenoic acid, docosahexaenoic acid, and vitamin A, their performance in memory tests improved significantly. In fact, their anxiety levels and cognitive function returned to levels comparable to those of non-stressed rats.
We also observed that the enriched diet helped normalize brain chemistry and the balance of gut microbiota, both of which were disrupted by stress. Importantly, these positive changes persisted into adulthood, indicating that proper nutrition during stressful periods could have long-lasting benefits.
By highlighting the protective effects of eicosapentaenoic acid within a nutritious diet, we suggest exciting possibilities for using diet to help manage stress and anxiety during key developmental years.
Our findings indicated that higher plasma levels of DHA, as well as omega-3 PUFAs in general, were linked to a lower risk of developing anxiety disorders. Specifically, we noted that participants in the highest quartile of PUFA levels, including DHA, showed a 14% reduction in the hazard of incident anxiety compared to those in the lowest quartile.
Further analysis of psychological symptoms revealed that those with elevated omega-3 PUFA levels, prominently DHA, experienced fewer adverse mental health issues. While we also considered white matter microstructures through neuroimaging with a subgroup of participants, the specific mechanisms behind DHA's positive effects on anxiety remain an area for future research.
Mice were divided into two groups: one received a food supplement containing DHA and eicosapentaenoic acid (EPA), while the other group was given a placebo. After three weeks, we found that the stressed mice treated with the omega-3 supplement showed significant improvement. They displayed less anxiety-like behavior and did not show the typical signs of depression, such as decreased interest in sweet foods, which reflects anhedonia.
Interestingly, our analysis revealed that omega-3 supplementation seemed to counteract the negative effects induced by stress, likely due to its anti-inflammatory properties. In non-stressed mice, DHA also helped minimize anxiety symptoms, suggesting that these benefits could extend beyond just those experiencing stress. Overall, these findings suggest that omega-3 fatty acids like DHA may hold promise as a treatment approach for anxiety, particularly in vulnerable young individuals.
What we discovered was quite revealing. The supplementation of fish oil rich in DHA—and another fatty acid, eicosapentaenoic acid (EPA)—not only reduced food intake and corrected glucose intolerance but also significantly improved anxiety and depressive-like behaviors in the mice. This was assessed through various behavioral tests that highlight changes in activity and mood.
Beyond the behavioral improvements, we observed that these dietary changes influenced brain chemistry as well. Fish oil supplementation promoted healthier brain lipid profiles and reduced markers of inflammation and microglial activation, which are known to be linked with a state of anxiety and depression.
These compelling findings suggest that incorporating DHA, alongside EPA, into our diets could potentially provide a natural way to alleviate mood and metabolic disorders triggered by obesity.

Frequently Asked Questions
Anxiety is a natural and often healthy emotion characterized by feelings of worry, nervousness, or fear about an impending event or situation. While some level of anxiety is a normal reaction to stress, excessive or chronic anxiety can become a mental health issue. It may present in various forms, from everyday worries to more severe conditions such as generalized anxiety disorder (GAD), panic disorder, or social anxiety disorder. Symptoms can manifest both psychologically, such as persistent worry and difficulty concentrating, and physically, including symptoms like increased heart rate, sweating, or fatigue.
Understanding the difference between normal anxiety and an anxiety disorder is crucial. Normal anxiety can be beneficial, motivating you to prepare for important events like exams or public speaking. However, when it starts to interfere with daily activities or leads to avoidance behaviors, it may indicate the need for professional help. Treatments for anxiety often include therapy, medications, and lifestyle changes, allowing individuals to manage their symptoms effectively. If someone is struggling with anxiety that impacts their quality of life, seeking guidance from a healthcare professional is a key step toward recovery.
Omega-3 fish oil is a nutritional supplement derived from the fatty tissues of fish, particularly fatty fish like salmon, mackerel, and sardines. It is rich in omega-3 fatty acids, which are essential fats that the body cannot produce on its own. The most significant types of omega-3s found in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are known for their numerous health benefits. These include reducing inflammation, supporting heart health, and promoting brain function.
Incorporating omega-3 fish oil into your diet can be beneficial if you don’t consume enough fish regularly. Many health experts recommend oily fish as a part of a balanced diet due to their high omega-3 content. For those who find it difficult to include fish in their meals, fish oil supplements can offer a convenient alternative, providing the same essential fatty acids in concentrated form. However, it’s essential to choose high-quality supplements that are third-party tested for purity and potency to avoid contaminants such as heavy metals or other toxins that can impact health.
Several studies have suggested that Omega-3 fatty acids, particularly EPA and DHA, may have a positive impact on anxiety. These essential fatty acids are found in fish oil and are known for their anti-inflammatory properties, which can influence brain health and functioning. Some research indicates that incorporating Omega-3 supplements into your diet might help reduce symptoms of anxiety, potentially by promoting neuroplasticity and improving mood-regulating neurotransmitters like serotonin and dopamine.
However, while the evidence is promising, it's essential to approach Omega-3 supplements as a complementary strategy rather than a standalone treatment for anxiety. It's always a good idea to consult with a healthcare professional before starting any new supplement regimen, especially if you're already on medication for anxiety or other mental health issues. Overall, while Omega-3 fish oil may be beneficial, it should be part of a comprehensive approach that includes therapy and healthy lifestyle choices.
Based on user reviews, the time it takes to see results from taking this supplement for anxiety can vary. Some users report experiencing immediate benefits, feeling a sensation of relief from stress and anxiety soon after they begin taking the product. For instance, one user mentioned, "When I began taking this vitamin, I experienced a sensation of relief as my stress and anxiety seemed to fade" (Read Review). Similarly, another user noted, "I feel my mood has calmed down" after starting their regimen, highlighting prompt improvements in anxiety levels (Read Review).
However, it is essential to note that not everyone may have the same experience. One reviewer shared that they faced insomnia and an anxiety crisis after starting the supplement, indicating that individual responses can vary widely (Read Review). In general, while many users seem to notice anxiolytic effects relatively quickly, effectiveness might take longer for others, making it advisable to monitor your feelings over time to assess how the supplement works for you.
Scientific research supports the potential of omega-3 fatty acids in alleviating anxiety, with various studies highlighting its effects across different populations. For instance, a systematic review of 23 trials found that taking omega-3 at a dose of 2 grams per day resulted in notable reductions in anxiety symptoms, though further high-quality trials are necessary for more conclusive evidence [3]. Additionally, a large study analyzing data from over 102,000 participants linked higher levels of omega-3 polyunsaturated fatty acids (PUFAs) to lower risks of anxiety disorders, suggesting that these fatty acids may play a significant role in improving mental wellness [24].
However, while the promise is evident, the evidence is not unequivocal. For example, a review showed that out of ten controlled trials, only one indicated a benefit for anxiety linked to a specific EPA dosage, leaving the overall impact on anxiety somewhat unclear [16]. Some studies emphasize variations in how different demographics respond to omega-3 supplementation, with gender and individual health factors influencing outcomes [12]. Overall, while omega-3 fatty acids like EPA and DHA show potential for improving anxiety, further targeted research is necessary to fully understand their efficacy and the mechanisms behind their effects.
Based on user reviews, many individuals have reported significant improvements in their anxiety and overall well-being after taking the supplement. For example, one user mentioned, "When I began taking this vitamin, I experienced a sensation of relief as my stress and anxiety seemed to fade," highlighting how the product helped them feel more grounded and calm (Read Review). Another reviewer shared that they felt their mood had calmed down, which is an encouraging sentiment for those dealing with anxiety disorders (Read Review). Users also noted reductions in irritability and increased energy levels, with one stating, "It has helped eliminate my fatigue, anxiety, and stress" (Read Review).
However, it's important to note that individual results can vary widely. While many users have found relief from anxiety symptoms, some reported negative side effects or ineffectiveness. For instance, one user experienced insomnia and an anxiety crisis after starting the supplement, indicating that the product may not suit everyone (Read Review). Overall, continuous use of the supplement appears to yield positive results for a majority, yet potential consumers should approach it with realistic expectations and monitor their personal reactions.(Read Review)
Based on user reviews, many individuals have found that combining this supplement with other products can enhance their anxiety management. Users have reported that omega-3 supplements complement their overall well-being, noting improvements in mood and reductions in anxiety levels. One reviewer mentioned that omega-3 not only alleviated anxiety but also relieved knee joint pain, showcasing its multifaceted benefits (Read Review). Another user found relief from heart pains associated with anxiety thanks to this supplement, indicating that it may work well alongside other remedies for anxiety (Read Review).
However, experiences can vary widely, and some users encountered challenges when combining omega-3 with other supplements. One reviewer experienced insomnia and an anxiety crisis after starting the product, suggesting that individual tolerances and reactions need to be monitored carefully when blending supplements (Read Review). Overall, while many report positive effects from using this supplement in conjunction with diet or other dietary supplements, it's advisable to approach with caution and consult a healthcare professional when integrating new products into your routine.
For those considering omega-3 fish oil as a supplement for anxiety, research points to a dose of around 2 grams per day as potentially optimal for reducing anxiety symptoms. In a systematic review of 23 trials involving nearly 2,200 participants, results indicated that this dosage could lead to notable decreases in anxiety, while lower doses failed to yield significant improvements [3]. However, it is important to note that the certainty of this evidence is low, and further high-quality trials are necessary for definitive conclusions regarding the efficacy of omega-3s in anxiety treatment.
Additionally, findings from larger cohort studies suggest that higher levels of omega-3 polyunsaturated fatty acids (PUFAs) correlate with lower risks of developing anxiety and depressive disorders [24]. This reinforces the notion that omega-3 fatty acids may play a significant role in supporting mental wellness, making them a valuable consideration for those looking to manage anxiety alongside their dietary choices.
Our findings indicated that higher plasma levels of DHA, as well as omega-3 PUFAs in general, were linked to a lower risk of developing anxiety disorders. Specifically, we noted that participants in the highest quartile of PUFA levels, including DHA, showed a 14% reduction in the hazard of incident anxiety compared to those in the lowest quartile.
Further analysis of psychological symptoms revealed that those with elevated omega-3 PUFA levels, prominently DHA, experienced fewer adverse mental health issues. While we also considered white matter microstructures through neuroimaging with a subgroup of participants, the specific mechanisms behind DHA's positive effects on anxiety remain an area for future research.
This limited data meant that a comprehensive meta-analysis on the effects of EPA on anxiety could not be conducted. As such, the impact of EPA specifically on anxiety remains unclear. It's important to note that although there was significant evidence for EPA's potential benefits for depression, we cannot confidently claim any similar effects for anxiety based on this review alone.
Overall, while we observed that EPA may help in managing depression, its role in alleviating anxiety requires further investigation. More high-quality research focusing on the unique aspects of EPA and its impact on anxiety will be essential for a clearer understanding of its therapeutic potential.
What we found was intriguing. In women with the restricting type of anorexia (AN-R), higher levels of EPA were linked to increased anxiety. In contrast, for those with the binge-purge type (AN-BP), higher EPA levels were associated with lower anxiety. This suggests that the same fatty acid can affect anxiety differently depending on the individual's eating behavior.
These findings open the door to tailored dietary interventions that could improve mental health outcomes for those struggling with anorexia nervosa. Understanding the relationship between fat consumption and emotional well-being can lead to more effective treatment strategies.
