Developed based on a thorough review of the scientific evidence, NutraOrigin's Omega-3 Fish Oil includes the highest quality, ultra-purified, molecularly distilled fish oil providing essential omega-3 fatty acids, and contains no artificial colors, flavors or preservatives. The research summary below will give you a better understanding of how Omega-3 Fish Oil delivers a broad array of health benefits.*

Healthy Aging
A recent study conducted by the University of California, San Francisco studied the effects of omega-3 fatty acids on the length of telomeres in the blood cells of over 600 individuals. (Telomeres are part of a cell's DNA, and the length of telomeres may be linked to biological aging - the longer, the better.) The researchers found that people who had higher levels of omega-3 fatty acids in their blood were more likely to have long telomeres - making them biologically younger than their real age - and vice versa.* (1)

Bone and Joint Health
Numerous double-blind, placebo-controlled human clinical trials have proven that fish oil supports joint health and mobility.* (2,3,4,5,6) The most likely reason is that omega-3 fatty acids contained within fish oil suppress the production of inflammatory mediators.* In one study, taking fish oil supplements led to a significant improvement in joint comfort compared to placebo.* (5) A survey of 120 patients placed by their doctors on fish oil supplements showed that 59 percent experienced improved joint health.* (7)

Initial evidence indicates omega-3s may also benefit bone health. A study of healthy young men found there was a positive association between the concentration of omega-3 fatty acids in the blood and the bone mineral density of the spine. In other words, the higher a man's omega-3 levels, the better his bone density.* (8) The same results were found in a trial of eight-year-old boys.* (9)

Cognitive Function
The importance of the omega-3 fatty acid DHA to brain health is evidenced by its high concentration within brain tissue: About a quarter of the fat within the brain is made up of DHA.* (10)

Research has shown that DHA is necessary for proper brain development in fetuses and infants, and getting enough DHA/EPA may also improve cognitive function in young as well as aging adults.* One large study of nearly 4,000 Swedish male adolescents found a definitive link between frequent fish consumption and cognitive function.* Young men who ate fish more than once a week scored almost 11 percent higher on intelligence tests than those who rarely ate fish.* (11) Similar results were obtained from a study on elderly adults aged 70-74 - the more fish participants ate, the better they did on a series of cognitive tests.* (12)

Eye Health
Epidemiological studies have consistently found a link between increased fish consumption and better eye health, particularly the health of the retina, which is susceptible to free radical damage.* (13) (The retina is the part of the eye that converts light into visual images.)

Healthy Pregnancy and Developing Child
Because omega-3 fatty acids are essential nutrients, needed by nearly every system of the body, fish oil supplements support both a healthy pregnancy and developing child.* Supplementation with fish oil during pregnancy has been shown to boost children's IQ, (14) motor function, (15,16) and social skills.* (17) Adequate intake of omega-3s also benefits healthy vision: in a randomized clinical trial, babies of breastfeeding women taking supplemental DHA experienced accelerated visual development.* (18)

Taking fish oil supplements is good for moms too. Research has shown that women who experience the post-partum blues have lower blood levels of DHA than those who feel fine.* (19) A randomized, double-blind, placebo-controlled study showed that fish oil supplements are more effective at boosting mood than placebo in post-partum women.* (20)

Heart Health
Fish oil is probably most well-known for its many documented cardiovascular benefits, supporting the health of both the heart and the blood vessels.* People who eat plenty of fish or regularly take fish oil supplements are significantly more likely to enjoy heart health than those who do not.* (21)

The omega-3 fatty acids EPA and DHA have been shown in multiple human clinical trials to maintain triglyceride and blood pressure levels that are already within a healthy range, support a normal heart rhythm and maintain normal blood viscosity:*

• One review study, which looked at the results of 47 different randomized clinical trials, concluded that fish oil positively impacts triglyceride levels.* (22)
• A meta-analysis that pooled the results of 90 randomized human studies likewise concluded that high intake of fish oil has blood pressure benefits.* (23)
• The ATTICA study, which examined the benefits of the fish-rich Mediterranean diet, showed that people who ate the highest amount of fish were more likely to have a normal heart rhythm than those who did not eat fish at all.* (24)
• EPA/DHA supplementation has been shown to help maintain normal blood viscosity, allowing blood to travel more easily through the vessels.* (25)

Mental Health
Supplementation with omega-3 fatty acids has been used with some success in supporting mental health and well-being.* A meta-analysis that pooled the results of ten double-blind, placebo-controlled clinical trials lasting four weeks or longer found that omega-3 fatty acids significantly improved mood.* (26) A preliminary double-blind, placebo-controlled study indicated fish oil supplements may also be effective for helping to reduce mood swings in susceptible individuals.* (27)

Weight
Being overweight may be related to insufficient levels of omega-3 fatty acids in the diet.* Population studies have found that, compared to their normal-weight peers, obese teenagers have lower levels of omega-3 fatty acids and higher levels of saturated fats within their cell membranes.* (28,29) A recently published study reported that the blood levels of omega-3 fatty acids in overweight and obese adults are, on average, 1 percent lower than those who are of a healthy weight.* (30)

Not surprisingly, taking fish oil supplements may contribute to weight loss.* A double-blind, placebo-controlled trial of overweight volunteers found that ingesting supplemental fish oil or exercising significantly reduced body fat.* (31) And when fish oil was combined with exercise, participants lost an average of 4.5 pounds in three months, while the combination of placebo oil and exercise did not cause significant weight loss.* (31)

Fish oil may work by increasing satiety - the feeling of fullness.* A recently published human clinical trial discovered that people who followed an energy-restricted balanced diet high in omega-3 fatty acids reported feeling fewer hunger sensations than those eating the same diet but low in omega-3.* (32)
