  • Purity – Cutting edge technology allows us to remove off-flavors during processing of OmegaRx 2. Furthermore, our new proprietary antioxidant blend provides far greater stability to protect its higher EPA and DHA concentration.
  • Value – OmegaRx 2 reduces the cost of a 2.5 gram serving of EPA and DHA by up to 11% compared to OmegaRx.
  • Expertise – If there is an acknowledged leader in the science and manufacturing of fish oil, it is Dr. Barry Sears.  His name is on every bottle of OmegaRx 2, so it has to answer to the highest possible standards.

Omega-3 Fatty Acids Are…

Omega-3 fatty acids are essential nutrients for human nutrition.  Initially, it was thought that the primary need for omega-3 fatty acids was to help increase membrane fluidity especially in the brain.  We now know their primary role is to resolve existing inflammation.

OmegaRx Fish Oil Contains…

The long-chain omega-3 fatty acids, EPA and DHA, are the building blocks for hormones called resolvins which are needed to resolve existing inflammation as well as accelerate the regeneration of new tissue.  To get these benefits, you need adequate levels of omega-3 fatty acids in the blood.

OmegaRx Purity Data…

  • PCB testing posted for every lot of OmegaRx produced
  • Fatty acid analysis posted for every lot produced
  • Rancidity Score (TOTOX) posted for every lot produced

The Best Way to Determine Your Dose Is…

The Cellular Inflammation Test can determine the levels of omega-3 fatty acids in the blood required for optimal resolution of inflammation.  The higher the score of this unique blood test, the more diet-induced inflammation is happening in the body.

You Need to Reduce Inflammation Because…

Diet-induced inflammation is one of the primary reasons why we gain weight, develop chronic disease, and age at a faster rate.  The ideal Cellular Inflammation Score is between 1.5 and 3.  For comparison, the average American has a Cellular Inflammation Score of 19 indicating a deficiency of EPA and DHA among Americans. This deficiency results in higher levels of cellular inflammation and chronic disease.

    This is a superior product. We will continue to purchase it. This is the highest quality fish oil supplement we’ve bought. And, the taste has improved a lot since we first tried it years ago. Delivery is slow.

    I have been taking the fish oil for 30 days now & really like the results. The taste & smell are really minimal. This will be a regular part of my daily vitamin intake from now on. Thank you Dr. Sears for another great product.

    I have bought a bottle of omegarx 2 for my kids, they are fine with the flavor and as a parent we are satisfied with this product.

    The only thing I don’t like is that it spills a little bit of product each time you use it. For a 80 dlls bottle you expect to not waste any amount of product.

    What a great improvement in strength, taste, and after all wellness, I use to mix it with my smoothies, and let me tell you that it is close to impossible to determine it is present. Highly recommended product. Cheer from Costa Rica.

    Have used fish oil from Dr. Sears for 14 years but thought I’d try the liquid after reading the reviews. Unfortunately, the fish oil odor was so strong I could not tolerate it and was not able to swallow it. I will return the liquid and reorder the capsules.

    I liked that it was stronger , but I am sorry but I am unable to use the RX2 , the awful fish taste lingers horribly in my mouth and I have to take a mouth freshener after to try to get rid of It and make sure others can’t smell it . Also the oil seems to get everywhere and taints everything it comes in contact with . I put on a vest while at home only to discover a terrible fish oil smell to it . I must have dripped a drop into it when taking a spoonful. I will have to go back to capsules , much more user friendly .

    Very minimal fish smell and taste.

    Going from Omega Rx to Omega Rx2 liquid, I definitely can feel an improvement in terms of calmness and focus. I do not concur with the reviews that state there is a fishy taste. Quite the opposite, the taste is virtually non-existent and even better than Omega Rx.

  9. 3 out of 5


    I concur with the reviews that mentioned the strong fishy smell and taste. Purity standards did not remove all “off-flavors”. I like the extra omega 3’s

  10. 3 out of 5


    Our family has enjoyed many benefits of Omega RX for the past several years, however the NEW Zone Omega Rx2 product taste extremely fishy and we have not been able to tolerate the taste or smell. We have now tried two bottles of Omega Rx2; both times a strong offensive fishy smell was released when the cap was removed and the taste was repulsive. The above stated concerns were never an issue when taking Omega Rx over the past several years. We are now awaiting a refund.

    Omega Rx changed my life in so many ways, but after taking Omega Rx2, I feel a whole different appreciation of what Dr. Sears has accomplished this time with the improvements, literally. Of course, I have no pain but I have a felling of calmness and emotional stability like never before. I am definitely burning more fat also. My workouts are yielding more positive results. Although, most impressionable is the way my skin feels. It is remarkably soft and youthful. I absolutely look younger. When I look in the mirror I stare at what I think are a reversal of aging. Can this be? I don’t know, but the proof is in the pudding, or fish oil! The last incredible trait is there is no fishy taste. Even my wife and son can take it straight from the bottle in a spoon without hesitation.

    We have been zoners for over 15 years and have taken the regular liquid fish oil and then later in years the tabs. We just received the new RX2 fish oil yesterday and took our first tsp dose this a.m. I have continually burped up the taste of the fish oil and was very much surprised because I have not experienced that with the other liquid or tabs. Is this the norm? Excited for this to come out in tabs (for convenience).

  13. 5 out of 5


    Wow, all I have to say going from Omega Rx, which was supposed to be the purist and most potent fish oil in the world, to the new kid on the block Omega Rx 2 is WOW. You can actually feel the difference. Barry Sears does it again!

Why do you need Omega-3 fatty acids?

Omega-3 fatty acids are the dietary building blocks to make powerful anti-inflammatory hormones. Without adequate levels of omega-3 fatty acids in the diet, cellular inflammation increases. Furthermore, they are critical for brain function. That’s why your grandmother told you that fish was brain food. Dr. Sears recommends at least 2.5 grams of EPA and DHA on a daily basis.

Why not just eat more fish?

To get the 2.5 grams of EPA & DHA omega-3 fatty acids Dr. Sears recommends, you would have to consume either (a) 7 pounds of lobster per day, or (b) 2 pounds of tuna fish per day, or (c) one-quarter of a pound of farm-raised salmon per day. Unfortunately, these sources are either too expensive (lobster) or have high levels of toxins (tuna and farm-raised salmon). This is why ultra-refined OmegaRx 2 is your best choice to get the 2.5 grams of omega-3 fatty acids for brain health and the reduction of cellular inflammation throughout your body at the lowest possible cost. Just 1 serving daily of OmegaRx 2 provides you with more than the recommended 2.5 grams of EPA & DHA omega-3 fatty acids.

What are the primary toxins found in Omega-3 fatty acids?

The primary toxins found in crude fish oil are mercury and PCBs. The mercury is easily removed since it binds to the protein and is easily separated in the initial purification. PCBs are extremely difficult to remove. Thus, the levels of PCBs in a fish-oil product are the true test of product purity. Dr. Sears makes PCB removal the #1 priority in his products. You can see in the following graph how his standards compare to others in the fish-oil industry.


Purity counts when choosing Omega-3 fatty acids.

The OmegaRx® brand is your guarantee of purity and potency. Purity comes from maintaining the lowest levels of PCBs possible in a fish-oil product. It makes no sense to purchase any fish oil that is not extremely low in PCBs since once they enter your body, they are not coming out. Potency is based on the actual amount of EPA and DHA in the oil. Your best purchase decision is when both are optimized.

What You Need To Know About Fish Oil Purity.

Although none of the marketing companies of the three primary brands (OmegaRx, Ultimate Omega, and Lovaza) of omega-3 products actually makes its own fish oil products, companies do set standards for raw materials they use for those products they sell. The more you know about these standards, the better the product choice you can make for yourself. All omega-3 fatty-acid concentrate products come from the same source, anchovies and sardines off the coasts of Peru and Chile. What separates the quality of fish oil are the purity and potency of the final products that can be quantified by the following tests.

PCB Levels

All omega-3 fatty acid products derived from fish oil will contain PCBs. To state otherwise is simply false. The question is the levels of PCBs in the finished product. The lower the levels of PCBs in a product, the higher the purity. Unlike other brands, Zone Labs has the strictest standards in the industry for the omega-3 products it uses. The international standard for the upper limit of PCBs is 90 parts per billion (ppb). That is fine for a health- food-grade product, but not for a professional grade. At Zone Labs our upper limit for PCBs is 5 ppb, which is 18 times more rigid than commonly used international standards. However, PCB levels will vary from lot to lot. This is why Zone Labs is the only company of the three major brands that posts the levels of PCBs on each lot of its omega-3 products on its Website for all to see. Testing for PCBs is expensive, but it is your guarantee of our commitment to product excellence and purity.

Totox Levels

Omega-3 concentrates are very prone to oxidation. Even after they are bottled or put into soft gelatin capsules, oxidation of the omega-3 fatty acids will continue. The World Health Organization (WHO) has developed strict standards to determine whether or not any edible oil is rancid and, therefore, whether it is suitable for human consumption. That standard is based on Total Oxidation (Totox) levels in the product actually being used. This is a rigid standard that governs all edible oil trading in the world. Since omega-3 fatty acid are exceptionally prone to oxidation, Zone Labs is the only company that posts the Totox levels on the finished product (not the raw materials) for every lot of omega-3 fatty acid product we make.

Fatty-Acid Levels

Like PCB and Totox levels, the levels of the omega-3 fatty acids EPA and DHA are key to your ability to reduce diet-induced inflammation. That’s why Zone Labs is the only company to post the levels of EPA and DHA in every lot of omega-3 products we sell to ensure product consistency. More importantly, we also offer a fatty-acid testing service through Zone Diagnostics ( that allows you to determine the actual amount of omega-3 fatty acids you require to help manage your levels of diet-induced inflammation.

Commitment to Ongoing Clinical Research

This means actually doing the research and publishing the results, not just supplying products. Zone Labs is the only company that sets aside a percentage of its product sales for continuing clinical research by the non-profit Inflammation Research Foundation. No other company has such a commitment to omega-3 fatty- acid clinical research. Zone Labs is also the only company headed by a leading medical researcher in the area of omega-3 fatty-acids.

Omega-3 Fatty Acids Are Only a Part of an Overall Anti-inflammatory Nutrition Program

The management of diet-induced inflammation requires the appropriate orchestration of the high-purity omega-3 fatty acids, adequate levels of polyphenols to protect the omega-3 fatty acids from oxidation in the body, and maintaining an anti-inflammatory diet to prevent the build-up of diet-induced inflammation. Zone Labs is the only company that offers a complete anti-inflammatory nutrition program for you. That’s why Zone Labs is the leader in anti-inflammation nutrition through our commitment to Evidence-Based Wellness®.

How do you know if you are taking enough OmegaRx® to make a difference?

Even taking OmegaRx® 2 will not make a significant difference unless you are taking enough. That’s why we say “test, don’t guess”. Using our Cellular Inflammation Test Kit, you can determine if you are taking the right levels OmegaRx® 2 that you need to reduce your levels of cellular inflammation.

Purity Counts when choosing Omega-3 Fatty Acids

We check every batch of finished product and post the results of that lot number on our website. Sure, it costs a lot of money, but our consumers deserve to know. There might be 5-star fish oils, but there is only one 6-star. That’s OmegaRx® because it has to meet the strict standards of Dr. Sears since his name is on every bottle.
