Science-Based Health Benefits of Omega-3 Fatty Acids

Science-Based Health Benefits of Omega-3 Fatty Acids

Omega-3 fatty acids can be found in both fish oil and krill oil which are commonly available as supplements. They both contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and are essential for health.

Omega-3 fatty acids are included in Antarctic Krill Oil by Beyond Vita®. 

1. Heart Health

Omega-3 fatty acid supplementation has been proven to help triglycerides and improve lipid profile.1

A review of several studies found that blood triglycerides decrease 25-30% after omega-3 supplementation.2

Researchers believe omega-3 fatty acids lower triglycerides by activating certain metabolic pathways that control triglyceride levels.3

Omega-3 fatty acids have also been shown to lower systolic and diastolic blood pressure by 4.4 and 4.1 mmHg respectively.4

In a randomized and controlled trial with 30 participants, omega-3 fatty acids reduced C-reactive protein and other inflammatory markers which are associated with cardiovascular issues. The researchers concluded omega-3 fatty acids may help decrease the risk of cardiovascular disease.5

A randomized double-blind and placebo-controlled study on 50 people found that omega-3 supplementation significantly improved endothelial function. As a result it may help improve cardiovascular health since endothelial dysfunction is linked to cardiovascular disease.6

Additionally, a meta-analysis of 16 studies supports the omega-3 fatty acid supplementation improving endothelial function.7

Omega-3 fatty acids may help improve heart health by lowering triglycerides, reducing inflammation and improving endothelial function.

2. Mood and Depression

Omega-3 fatty acids are an important building block of the brain and may help improve depression.8

In a randomized and placebo controlled trial on 23 young adults with depression, researchers found that 67% of the omega-3 fatty acid group no longer met the criteria for depression after 21 days supplementation.9

Another double-blind and placebo controlled study also found a significant decrease in depressive symptoms in patients with depression after omega-3 supplementation.10

Researchers also reported omega-3 fatty acids have significant antidepressant efficacy in a meta-analysis of 10 studies with 329 participants.11

Omega-3 fatty acids may help improve mood and reduce the symptoms of depression.

3. Eye Health

The omega-3 fatty acid DHA is a major component of the retina in the eye and a deficiency may result in vision problems.12,13

In a 2014 study researchers found that low blood omega-3 fatty acid levels were strongly associated with age-related macular degeneration.14

Omega-3 fatty acids may help improve eye health and reduce the risk of macular degeneration.

5. Cognitive Function

Omega-3 fatty acids are essential for brain health and higher levels have been associated with better mental performance in adults.15

Research has also demonstrated an improvement in working memory after omega-3 supplementation.16

A randomized controlled trial with 176 participants demonstrated omega-3 fatty acid supplementation can improve the reaction time and memory of healthy adults.17

Additionally, omega-3 supplementation may be beneficial at the onset of Alzheimer’s disease.17

Omega-3 fatty acids may help improve cognitive function.

6. Liver Health

Omega-3 supplementation may improve non-alcoholic fatty liver.18

In a 2012 meta-analysis of 9 studies involving 355 participants, omega-3 supplementation was found to decrease liver fat in patients with non-alcoholic fatty liver disease.19

Omega-3 fatty acids may help improve liver health and reduce liver fat in non-alcoholic fatty liver disease.

7. Helps Reduce Joint Pain

Omega-3 supplementation may be able to reduce joint pain in patients with rheumatoid arthritis.20

In a study on 250 patients with non-surgical neck or back pain, omega-3 fatty acid supplementation resulted in 59% of participants discontinuing their prescription NSAID for pain and 80% reported they were satisfied with their improvement.21

Omega-3 fatty acids may help reduce joint pain.

8. Menstrual Issues

In a randomized and controlled trial, researchers concluded that omega-3 fatty acid supplementation can help reduce dysmenorrhea or menstrual pain.22 Two other randomized double-blind and placebo-controlled studies also support omega-3 fatty acid supplementation for reducing menstrual pain.23,24

Additionally omega-3 fatty acids may help alleviate premenstrual syndrome symptoms (PMS). In a 2013 randomized double-blind and placebo controlled study, omega-3 fatty acid supplementation resulted in reducing bloating, headaches, breast tenderness, anxiety, depression, bloating and nervousness in 124 women with PMS.25

Omega-3 fatty acids may help reduce menstrual pain and alleviate premenstrual syndrome symptoms.

9. Helps Improve Sleep

Obstructive sleep apnea patients are more likely to have low levels of the omega-3 fatty acid DHA in their blood.26

In a 2014 randomized double-blind placebo-controlled trial, researchers found that omega-3 supplementation led to 58 minutes more sleep per night and 7 fewer awakenings.27

Omega-3 fatty acids may help improve sleep.

10. Stress and Adrenal Health

Increased intake of omega-3 fatty acids has been shown to help reduce basal cortisol secretion in a three week randomized, double-blind and placebo-controlled trial.28

In another three week study, researchers reported that omega-3 fatty acids help inhibit the activation of the adrenals and cortisol release during periods of high mental stress.29

Omega-3 fatty acids may help improve adrenal health by preventing elevated cortisol levels.


Omega-3 fatty acids are essential fats that may help improve heart health, reduce joint pain, improve mood, reduce depression and improve cognitive function in addition to other benefits.*
