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 your body is impacted by diet-induced inflammation.

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.

  1. Yvette Paulusz


    I am interested in purchasing the liquid form of Fish Oil (Rx2), but I’m uncertain about dosage, because teaspoons are not standard, but vary in size. So I’d like to know:
    how many ml. should a healthy adult take per day? and
    how many ml.should a healthy adult with a ‘frozen’ shoulder take, per day?
    Please answer with regard to both conditions.
    P.S. I have n’t actually tried the product yet, but can’t submit my enquiry unless I rate it, so I rated it as average. I hope and expect it will turn out to be much better than that!

    • Dr. Sears’ Zone Customer Support

      Yvette, Thank you for your question. One teaspoon of Dr. Sears’ OmegaRx 2 Liquid equates to 5ml and provides you with 3,375mg of EPA and DHA. This 1 teaspoon is our recommended dosage for any adult utilizing our OmegaRx 2 Liquid regardless of condition. Thank You, Dr. Sears’ Zone Customer Support

  2. Norma Saris

    I have only been using this fish oil for 2 days so I cannot speak to its health benefits. It is unique in that it needs to be kept in the freezer after opening. That is not a problem. No burping or fishy taste after taking it. I think I will do fine with it.

  3. Sumitra

    “The reason only a small amount of natural lime oil is used is due to the fact the over utilizing flavoring with an Omega-3 product can cause higher amounts of unwanted oxidation.”
    What is it you are trying to say? The sentence makes no sense. Please explain in a clear.
    Thank you!

    • Zone Customer Support

      Sumitra, Thank you for your question. An Omega3 fish oil liquid is easily susceptible to oxidation, or rancidity, if it is not properly handled. One item that can cause oxidation in a fish oil liquid is flavoring, especially if it is used in high concentrations. To avoid this problem, Zone Labs only uses a small amount of natural lime oil as flavoring with our oil. We hope this clears it up for you. Thank You, Dr. Sears’ Zone Customer Support

  4. Randy Brown

    This fish oil is top notch. I’ve been taking it for years. My only issue is the pouring mechanism of the bottle. It’s fine but I’m constantly in trouble with my wife because I’m not too good at making a clean pour. Compare this to the Zone Olive oil pour mechanism. I can pour that one perfectly without ever spilling a drop. Why? I think it is the plastic flute pour mechanism on the olive oil bottle compared to the flat plastic pour mechanism on the fish oil bottle. Any chance y’all could switch to something like what you already use on the zone olive oil bottles? It might be good for my marriage….

  5. yougbav (verified owner)

    I dont’ like fish. I don’t eat fish. I don’t like the taste or texture of fish. The reason I have tried and discontinued fish oils on several occasions is the fishy taste and the fishy burp. Not sure I will be able to finish two bottles of the stuff, even if I eat something immediately afterwards. I haven’t see any health benefits after two weeks. And the bottles drip and then leave fish oil on my fingers which I smell for another 3 hours unless I work hard to wash the fishy smell off. I have tried a competitive product that doesn’t have a taste at my doctor’s office. I bough this product because I thought it would be better than what my doctor recommended.

  6. Cheron

    Been taking the fish oil for years. Helps with my skin and overall well- being

  7. Richard (verified owner)

    It taste differently than the last I bought. More smelt fish than the last one. Why?

    • Zone Labs Customer Support

      Richard, Thank you for your question. Dr. Sears’ liquid OmegaRx 2 product is an all-natural Omega-3 supplement that utilizes a small amount of natural lime oil as the flavoring system. The reason only a small amount of natural lime oil is used is due to the fact the over utilizing flavoring with an Omega-3 product can cause higher amounts of unwanted oxidation. Based on this, you can expect there to be some variation from lot to lot in regards to the overall flavor. Thank You, Dr. Sears’ Zone Customer Support

  8. Don

    Best EPA/DHA of anything i have found on the market.

  9. Conn Rusche (verified owner)

    I became sensitive to glycerin in the capsules (and other supplements) and switched to the liquid form of OmegaRX. I now enjoy the wonderful benefits of omega-3 oils in the liquid format. I find this product also is a great benefit for my dry-eye condition.

  10. Jeff

    I have taken the capsules for 12+ years and recently decided to give the liquid a try. I was very pleased to find it easy to take with little if any taste or smell. Great product.

  11. Ken F.

    I am told that this one is the best on the market so I have been taking it for years. And there is usually no fishy smell or after smell if you keep it in the freezer.

  12. Jim Barrett (verified owner)

    Easier to take than the capsules and better than I had expected. Best on the market!

  13. IRFAN

    Hi ,
    In one of your blog you were recommending to give 10-15grams of EPA+DHA for child with autism. Do you have any studies indicating benefits from this large therapeutic dosages ?
    I have 5 year child with autism and would like to know your recommended omega 3 product and dosage .

  14. Martie LeRoy

    I take the fish oil because of its health benefits. I would love to know of a product that takes the fish oil smell off anything that it comes into contact with. I am currently using lemon juice.

  15. Diane (verified owner)

    Are there any recommendations on the dosage for a 2 year old child? I was giving them a quarter of a teaspoon since the adult dose is 1 teaspoon.

OmegaRx 2 Microcapsules Identical concentration and purity as OmegaRx 2 capsules, but half the size, with the same quantity of servings per bottle.
OmegaRx 2 Sport Capsules Identical purity as OmegaRx 2 capsules, but higher EPA content to help athletes with performance. Also contains GLA and toasted sesame oil to enhance the effect of EPA and DHA on muscle recovery.
OmegaRx 2 Liquid Identical concentration and purity as OmegaRx 2 capsules, but designed for people who prefer a liquid fish oil. Liquid may also be easier to swallow for children.

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.

Your fatty acids are now even easier to get with OmegaRx2.

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.

PCB in Fish Oil

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 (www.zonediagnostics.com) 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 test every lot of finished product and post the results of every report because our consumers deserve to know what they’re taking. There might be 5-star fish oils, but there is only one 6-star: that’s OmegaRx. To have Dr. Sears’ name on every bottle, it has to meet his strict standards for concentration, purity and stability. See how our fish oils measure up.
