Fish Oil Omega 3 and PCB’s

What Are PCB’s And How Do They Affect Omega 3 Supplements?

When you think of Fish Oil Omega 3 as a healthy way to supplement this important nutrient, you may not think of potential hazards associated with it. Unfortunately, during a period of time between the 1920’s and 1970’s PCB’s (Polychlorinated Biphenyl) was used in manufacturing certain things such as; plastics, tapes, insulation, fluorescent lights and paints.

PCB’s were found to be very stable and therefore, did not break down. This made for strong products, but once released into the environment these chemicals remained in our soil, water, air and even contaminated food supplies. This chemical has been banned in the United States since the late 1970’s, but unfortunately water tested still today contains traces of the chemicals.

What this means for people taking Omega 3 supplements made from fish oil, is that you need to be checking the labels of your products to make sure they are tested for PCB levels. There have been cases of products on the market that have been found to have unusually high levels. However, there are product manufacturers that do proper testing and keep their product within Proposition 65 limits.


Proposition 65 Limits For Fish Oil Omega 3 Supplements

reg-logosThe Food and Drug Administration set an acceptable level for PCB’s in fish at 2 parts per million or 2 nanograms. Cancer causing levels of PCB’s start at around 90 nanograms, so what this means is any manufacturer making fish oil supplements is held to very strict standards.

What needs to be understood, is that all fish contain trace amounts of PCB’s so it is literally impossible to find PCB free fish sources to make supplements from. What a manufacturer can do is make sure their sources have the lowest amount of PCB’s possible and perform product testing regularly.

One way to make sure that you are getting a product that conforms to Prop 65 standards is to make sure it is made in an “FDA registered facility.” What this means is the FDA recognizes the standards the facility has set for its product. It doesn’t mean FDA approved, but that the manufacturer holds to FDA standards for all stages of product development.


Find Omega 3 That Is As Pure As Possible

Our environment is not as clean as it once was before chemicals and synthetics were brought into the picture. These things caused pollution of our air, water and food supplies. Unfortunately, some chemicals cannot be removed completely. What our product manufacturers can do is make sure that they are releasing the purest form possible for your health and safety.

One way this is done is by molecularly distilling the fish oil to remove as many toxins as possible. While it is not possible to completely remove all of the toxins, look for products that are as close to 100% pure as possible.

It removes toxins and heavy metals without causing any harm to the actual product. It is also a way to remove nearly all toxins leaving a near pure product, without compromising quality.



When choosing an Omega 3 supplement made from fish oil, be sure to check if the manufacturer has addressed PCB’s and the purity of the product. This will ensure your health and safety while supplementing a very necessary nutrient.
