Criteria Used for Evaluation

Product Purity

EPA and DHA amounts alone were not enough to determine whether or not a product was able to be classified as one of the best. With several fillers, additives and artificial ingredients found in many of the researched products, purity became an important area of investigation. While many of these products advertise a specific molecular distillation process to ensure ultra-refined fatty acids, that doesn’t mean that the product at hand is essentially “pure.” Not only were things like soy, animal parts, unnecessary ingredients or laboratory cross-contamination was taken into account, but also mercury and PCB levels for products. The fewer additives and lower toxin levels, the purer the product.

While some of these products boast titles such as “NON-GMO verified” or “Third-Party Purity Tested,” an additional claim to look for on the product’s packaging is “IFOS Certified.” IFOS stands for the International Fish Oil Standards Program. This program is the only third-party testing system created to exclusively test and approve fish oils. Since it is the only exclusive testing system, this certification can assure those consumers interested in receiving the ‘best of the best” standards when it comes to supplementing their diet.

Use

Fish oils have been shown to reduce muscle soreness, increase blood flow, and prevent muscle breakdown, all of which are important for longevity and endurance in the sport of running. That being said, not all are created equal and because the body cannot make its own fatty acids, it is crucial to find good products to receive these benefits.

Since most are large pills taken orally, the number of pills per serving was taken into account. While all of the products on the list range from 1 to 3 pills per serving, the higher the serving (and especially when combined with a low potency per serving) meant that it did not fare well in this area. The products offering the lowest serving and maximum dose of Omega 3s scored best.

How much fish do you already consume? A diet high in fish, like a Mediterranean style diet, will already provide a healthy amount of omega 3s and a higher potency product is not necessary to supplement. More benefits are found from consumers who do not eat a largely fish-based high-fat diet.

Value

Fair pricing was determined by the combination of potency, purity, and serving. If a product is highly potent, but not essentially pure, it is not worth as high a cost. Additionally, a cheaply priced product per pill with a high serving content does not correlate into a good value for consumers. The best value was determined by matching the highest potency and purest supplement per price point.

Other Factors to Consider

Bottom Line

Health benefits needed
When considering which product is right for you, it is important to determine which benefits you are looking to find. High endurance athletes can take note of the promoted benefits of joint and heart health. Those opting more for a healthier lifestyle in addition to moderate activity might want additional benefits like Vitamin D to be found in their supplement and will not need to consider a highly potent formula as heavily.

Health Precautions
It is always important to speak with your healthcare provider. Fish oils may affect blood sugar levels and cause low blood pressure, so consumers sensitive in those areas need to proceed with caution. Additionally, any consumer with an allergy should avoid these products and opt for a plant-derived option. Lastly, taking note of the mercury and toxin levels of your particular supplement is important to make sure you are not adding an unsafe level of contaminants to your diet.

Versatility

Even with the popularity of online retailers, being able to find a product at your local store can make life simpler. We took note of whether or not these products were accessible at the local pharmacy, supermarket or health food store in addition to being able to be purchased online and delivered to your home. If a product were available in multiple places, it became more accessible and ranked higher in that area.

Potency

EPA and DHA are extremely important in proper cell membrane function, general cardiovascular health, and brain support. Since it can be challenging to get enough EPA and DHA through diet alone, it is essential to find a product that provides a high serving of these two Omega 3s. Therefore, we looked at the ratio of EPA to DHA in each product, as well as how much of the total product was made from these two fatty acids to provide a potency ranking.

Frequently Asked Questions

q: Q: Why should I focus on increasing specifically my Omega 3 intake?
a:

As a general rule, most diets are very high in Omega 6s, but lack of Omega 3s. Sources of Omega 6 fats include vegetable oils, salad dressings, mayonnaise, nuts, and seeds. These Omega 6 sources are more readily obtained and consumed than those products with Omega 3s, like seafood, crab, and oysters. While both of these fatty acids are important in keeping a body working properly, the Western diet is predominately heavy in providing Omega 6s. Therefore, finding a supplement that provides ample amounts of Omega 3s will help balance the Omega 6 to Omega 3 ratio in your diet.

q: Q: Are fish oil supplements safe for all ages?
a:

While the Dietary Guidelines for Americans includes a recommendation that adults eat 8 or more ounces of seafood a week, with amounts varying by age for younger consumers, it is recommended that those who are pregnant or breastfeeding avoid or limit certain types of seafood due to the potential toxins. Supplements should also be used with this same caution in children and pregnant or breastfeeding women, for these same reasons, as there is potential to consume harmful toxins that can affect the nervous system of a fetus or young child.

q: Q: What are the potential side effects of taking fish oil supplements?
a:

While side effects are uncommon, they can occur. Some gastrointestinal issues may arise, including burping and indigestion.

q: Q: Outside of benefits for athletes, what other benefits might I get from taking a fish oil supplement?
a:

Daily intake of EPA and DHA has been linked to a reduced risk of sudden heart failure. Many studies link fish products to improving the symptoms of rheumatoid arthritis. There is also evidence to support the idea that consuming omega 3 fatty acids can reduce the risk of abnormal heart rhythms. Supplements have also been linked to possible benefits for the following conditions: ADHD, Autism, bipolar disorder, dementia inflammatory bowel disease, liver disease, multiple sclerosis, osteoporosis, Raynaud’s disease, schizophrenia, and more. Continuing research is underway to study any benefit to eye disease, asthma, and organ transplantation outcomes.

q: Q: Who should avoid consuming fish oil supplements?
a:

Those with an allergy, those who are vegan, children, breastfeeding moms, and pregnant women should consult their physician before proceeding with supplements to their diet. It is also important to note the added ingredients on a specific product label and avoid any dietary restriction item that is included, like soy, gluten or animal part products.

q: Q: How long has fish oil supplementation been used and studied?
a:

As early as the 16th century, fishermen in England were using these products to treat a variety of health issues such as wounds, aches, and colds. A Danish study from the 1970’s, which focused on Greenland Eskimos, showed researchers that despite consuming a very high-fat diet, these Eskimos did not have a high incidence of cardiovascular disease or heart attack. The low incidence of heart problems was concluded to be related to the high concentration of Omega 3 fatty acids consumed in their diet. This study sparked a greater interest in studying the benefits of these products. It also provided enough evidence to conclude that people who eat seafood at least once a week are less likely to die of heart disease than those who do not consume seafood.

q: Q: Are all fish oils the same?
a:

No, in fact, fish liver oils are not the same as fish oils. Fish liver oils, like from cod, have Vitamin A and Vitamin D in addition to omega 3s. Vitamin A and Vitamin D can be toxic when consumed in large doses.
