Flogging fish oil supplements is a lucrative business. Initial studies suggested that this was money well spent. Omega-3 fatty acids were shown to help maintain a healthy heart. However, a few recent studies seem to contradict this. Does that mean omega-3 fish oil supplements are a waste of money? Omega-3 fatty acids are a group of essential polyunsaturated fatty acids. We rely on sources such as fish and shellfish, or supplements, to get enough.
The supplements usually contain two important types of omega eicosapentaenoic acid EPA and docosahexaenoic acid DHA. Evidence from early clinical trials demonstrated that omega-3 fatty acid supplements can reduce the risk of cardiovascular disease. More recently , researchers at Stanford University analysed the data from 19 studies that included nearly 46, people from 16 countries. Suffice to say, oxidized lipids are not a good thing. Rather than protecting heart health, as fish oil supplements are supposed to do, they can do damage:.

What better way to understand the ins and outs of the fish oil world than to interview an insider. To get the inside scoop on what to look for in a fish oil supplement, I interviewed a friend who works at a high end supplement manufacturer. We could also see some of self-emulsifying technologies you would generally see utilized in lipophilic pharmaceuticals applied to your fish oil products. In my opinion, until we see these technologies backed up by good studies, consumers would be best served being directed towards a high quality oil in the re-esterified triglyceride form like we list below.
A large majority of fish oil used to create marine-derived omega-3s come from small, fatty fishes like: sardines, mackerel and anchovies.
A Fish Oil Story
Other sources include: tuna, cod, salmon, herring among a few others. This can vary greatly from brand to brand. That would mean, a large majority of the fish oil products sitting on the retail shelves contain the oil from fish were harvested in That is difficult to say … being that the fish oil industry has now been going strong for several decades, many of the quality control issues that once existed such as heavy metal contamination, toxins pesticides and oxidation are rare today.
With that being said, there have absolutely been instances of unacceptable levels of these contaminates being found in products in the retail setting. Note : When I clicked through to the GOED website, most of the links to members were broken, and General Mills was listed as a member, so caveat emptor. This is probably one of the most misunderstood steps in the manufacturing process.
The idea that heat used in the distillation process oxidizes the oil is completely unfounded. During the molecular distillation the oil is exposed to low heat in a vacuum setting, no oxygen is present during this step that could potentially lead to oxidization of the oil. This necessary step removes many of the undesirable free fatty acids and contaminates present and concentrates the oil down to the desired EPA and DHA content. The studies leveraged by these companies are generally poorly designed, utilize different dosages, do not specify forms, wrong outcome measures, single dose, etc.
While the studied dose 1. This is a conversation I have almost daily with clinicians looking for a fish oil to recommend to their patients. These European labs operate under standards much higher than even the United States Pharmacopeia USP , testing for a number of additional contaminants ensuring your fish oil is of the highest quality. The easiest way to verify the purity of your fish oil is to ask the manufacturer for a Certificate of Analysis COA for your specific batch.

There are currently four 4 primary forms of omega-3s available in supplemental delivery. This is a source of a lot of confusion for consumers looking for the most bioavailable omega-3 oil. Omega-3s occur naturally in the triglyceride form so it would make sense to supplement in this form as well and the nutritional sciences suggest just that. There is a cheaper, faster manufacturing process that yields what is called an ethyl ester EE. This semi-synthetic form of omega-3s contains an ethanol backbone that have shown difficulties in both absorption and bioavailability how well it is incorporated into cell membranes.
A large majority of fish oil is in the EE form. These last 2 forms are driven more heavily by marketing then they are actual science, further contributing to the confusion. Many companies will attempt to deceive consumers by boosting amount of omega-3s but when you look at the supplement facts box you find a fairly low content of EPA and DHA. Therapeutic ranges fall anywhere between 1 and 6 grams per day depending on clinical conditions.
For compliance reasons, the fewer capsules someone has to take the more likely they are to stay complaint and reap the well documented benefits of fish oil supplementation.
