Omega-3 fatty acids are one of the major classes of polyunsaturated fatty acids, with another one being omega-6 fatty acids. Omega-3 fatty acids statistics show that they are commonly found in most animal foods and plants, and that they cannot be synthesized in the human body.
Unlike most fats that are simply stored or used as energy, omega-3 fatty acids play other vital roles in the body. They have numerous health benefits crucial to the proper functioning of the human body.
Omega-3 deficiency is linked to several health problems such as depression, lowered cognitive abilities, heart disease, arthritis, cancer, and several autoimmune diseases.
That’s why we compiled relevant facts and statistics on omega-3s to help you learn more about these fascinating fatty acids. Dive in to find out more about omega-3s, their benefits, dosage, market value, etc.

General Omega-3 Fatty Acids Facts You Should Know
1. Omega-3 fatty acids are a class of polyunsaturated fatty acids.
(Office of Dietary Supplements)
Omega-3 fatty acids have a carbon-carbon double bond positioned three carbons away from the methyl end of the chain. While several other omega-3s exist, scientific studies mostly focus on alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA).
2. EPA and DHA are originally produced by microalgae.
(Office of Dietary Supplements)
While fish and fish oils are popular EPA and DHA sources, these omega-3 fatty acids are first synthesized by microalgae. Omega-3 fatty acid facts show that fish are rich in DHA and EPA because they are consuming these phytoplanktons and storing omega-3s in their tissue.
3. The human body cannot synthesize omega-3 fatty acids.
(Healthline)
Because the human body is not capable of producing them, and because they are vital nutrients, they are known as essential fatty acids and must be obtained from food.
4. ALA must be converted to EPA or DHA before it can be utilized for something other than energy.
(Healthline)
However, the process is said to be inefficient as only 0.5%–5% of ALA can be converted to DHA and 1%–10% to EPA in the human body. ALA that is not converted or stored is a type of omega-3 fatty acids used for energy only.
5. Omega-3s have an absorption rate of 95%.
(Office of Dietary Supplements)
When omega-3 fatty acids are ingested, they are hydrolyzed in the intestinal lumen. The hydrolyzed products are then incorporated into bile salt by passive diffusion. These products enter the blood and are delivered to various organs for use.
6. The mean value for plasma phospholipids EPA and DHA among US adults not taking omega-3 supplements is between 3%–4%.
(Office of Dietary Supplements)
Omega-3 status is determined by measuring the individual omega-3s present in the plasma phospholipids and showing them as the total phospholipid omega-3 fatty acids percentage by weight.
7. The typical diet in the Western world contains 10 times more omega-6s than omega-3s.
(Healthline)
Processed foods, which constitute a significant part of the Western diet, are a rich source of omega-6. To enjoy the beneficial effects of omega-3s, the omega-6s to omega-3s ratio should be closer to 2:1.
8. Omega-3 deficiency can cause scaly skin and dermatitis.
(Office of Dietary Supplements)
A deficiency of omega-3 fatty acids results in a significant reduction of the plasma and tissue concentration of DHA. This can cause brittle hair, dandruff, dry skin, fatigue, sleeping problems, thin nails that peel and crack, etc.
Common Sources of Omega-3 Fatty Acids
9. Algal oil is a good source of omega-3s for vegetarians and vegans.
(UW Integrative Medicine)
Although algal oil derived from aquatic plant-like organisms is rich in EPA and DHA, most algal oil supplements primarily provide DHA. They are, however, rarely contaminated as these organisms are at the bottom of the food chain.
10. There are high concentrations of EPA and DHA in fish oil.
(UW Integrative Medicine)
Omega acids from fish oil are derived from oily fishes like herring, mackerel, sardine, tuna, and anchovies. There are about 180 milligrams of EPA and 120 grams of DHA in every gram of fish oil.
11. There are 2,682 milligrams of EPA and DHA in one tablespoon of cod liver oil.
(Healthline)
Cod liver oil is obtained from the liver of codfish and is different from fish oil. It is rich in omega-3s as well as vitamins A and D.

14. Some brands of eggs and soy beverages may be fortified with omega-3s.
(Office of Dietary Supplements)
Some manufacturers now fortify their yogurts, juices, milk, and infant formulas with omega-3s, particularly DHA.
15. Krill oil contains significant amounts of EPA and DHA fatty acids.
(UW Integrative Medicine)
Krill oil is derived from krill, a shrimp-like crustacean. While omega-3 fatty acids from krill oil are of the same quality as those derived from fish, their concentration is not as high.
16. Beef from grass-fed cows may contain increased levels of omega-3s.
(Office of Dietary Supplements)
Generally, beef from grain-fed cows contains low amounts of omega-3s, but the levels of these fatty acids increase when cows are fed mostly grass. ALA is the primary omega-3 fatty acid found in grass-fed cows.
17. Soybean is a rich source of ALA and has many health benefits.
(Healthline)
It can provide nutrients, omega-3 fatty acids, and vitamins. It is rich in ALA, fiber, vegetable protein, potassium, magnesium, vitamin K, and riboflavin. Typically, 100 grams of soybeans contain 1,443 milligrams of ALA.
18. There are 23 grams of ALA in every 100 grams of flax seeds.
(UW Integrative Medicine)
