Adequate intake of omega-3 fatty acids can begin to rapidly reduce diet-induced inflammation. Dr. Sears started the fish oil revolution in 2002 with his landmark book The OmegaRx Zone, and Zone Labs continues to lead it with OmegaRx,® which is the standard to which all other leading omega-3 fatty acid products are compared as shown the chart to the left.

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.
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.
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.

When it comes to PCB standards in fish oil product, which would you choose?
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.
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.
