    It is a great product for kids.

    I take 2 – 4 tablespoons a day. After I take it I drink a little tonic water and that keeps any “fishy” taste at bay.||The only improvement I would suggest is to come up with a better bottle to keep the fish oil from running down the sides. I know here are better bottles out there from past experience.

    I bought this product after reading the book and changing my diet from vegetarian to pescaterian when I realised that the benefits to my mental health would be great, and I could still eat fish in a more ethical and sustainable way. I love this product! Not only have I noticed my moods improve and general feelings of belatedness around that time of the month, But I’ve noticed a marked decrease in my appetite which makes it easier to go for the healthier options when eating out since I’m not craving anything. I have suffered from Bi Polar Disorder for many years and in the last two years I have been off my medications experimenting with alternative routes. One such route was cognitive behavioural therapy & NLP which has worked extremely well for me, however there are certain aspects of this disorder which in my opinion are physical. Since there has been some research into the effects of inflammation on the brain and how Omega 3s (specifically DFAs) can help reduce inflammation whilst supporting brain growth & health, I thought I would try this fish oil – especially since I would be taking larger than normal quantities (I use roughly 1 Australian size Tbsp per day) – I wanted to make sure it was as free from contaminants as possible. So here I am! RAVING about this product. I feel my moods are generally more stable and if I hit a rough patch it’s easier and faster for me to move forward than it was before. Now, granted I have changed other things in my lifestyle such as diet and exercise – but these things have only been very recent changes, whereas the fish oil has been something I’ve used for a while and I feel it’s helped me get to the point where I can actually make the diet and exercise changes almost effortlessly. Of course it could also be the placebo effect….however I highly doubt that – based on all the research I’ve read. Anyway, discover for yourself! It’s the best on the market in my opinion, in terms of it’s purity and the amount of Omegas you get per serving.

    I add 1 TBSP daily to my water with a little juice to change the taste and make it more palatable.

    I have been using fish oil every since I read the research on Dr. Sears. My husband has suffered with severe allergies for years and after reading how fish oil affects inflammation he started taking fish oil. Results weren’t seen right away but after taking large doses of fish oil the symptoms improved dramatically. His focus improved energy increased sneezing subsided eyes didn’t itch and he was even able to be outside for short periods. I suffered from Ménière’s disease and found the inflammation in my ear. As I took fish oil, it improved dramatically as well. We tried several brands and stayed mostly with the costco brand which ich seemed reliable and from wild salmon however I had a hard time taking so many capsules and decided to try the liquid. Not only does his have very little taste, none with water, but I never had an after taste or belching of fish. It went into my system almost immediately and I could feel the results quickly. My husband was a little skeptical of my description but after even his first dose he was sold. We now will only buy the liquid. After working in the yard all morning my eyes were itchy, my glands were swollen and I started feeling bad. I took two teaspoons and soon felt better. Severe allergies no longer keep us from going outside….thank you zone labs!

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, which you can get from just 4 OmegaRx capsules.

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 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 4 capsules daily of OmegaRx provide you with 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® will not make a significant difference unless you are taking enough. That’s why we say “test, don’t guess”. Using a simple finger-prick test from Zone Diagnostics, you can determine if you are taking the right levels OmegaRx® that you need to reduce your levels of cellular inflammation.
