Does Your Fish Oil Eat Through Plastic?
Do you take a fish oil supplement? Here’s a quick way to test fish oil quality:
Get a styrofoam egg carton. Cut out one of the styrofoam egg cups. Set it open side up (like a little bowl) inside a clear glass. The glass must be made of glass, not plastic, for this to work.
Put a small amount of fish oil in the egg cup. You can either pour in a small amount of liquid or break open a capsule and pour the fish oil into the egg cup.
Then wait. Over the next 15 minutes, you will see one of three things:
1.  Nothing will happen. The oil will just sit there in the egg cup.
2.  A little bit of bubbling and oozing will happen. A small amount of the oil will ooze through the styrofoam, and you’ll see it in a little pool or smudge on the bottom of the glass.
3.  All or most of the fish oil will permeate through the styrofoam and collect in the bottom of the glass. A small amount of residue may be left in the egg cup.
Okay, so what does this mean?
1.  If nothing happens, then the fish oil is not ultra-refined. In other words, the molecules in the fish oil are larger than they are in ultra-refined oils. The larger molecules mean that your body will do less well at absorbing and getting benefits from this fish oil. Less refined oils may also look cloudy, because they contain other fatty acids that are basically useless. This is an inferior grade of fish oil.
2.  If a little bit happens, then the oil is moderately refined. Again, it contains many molecules that are fairly large, so it won’t be absorbed by the body as well as it could be.
3.  If all or most of the oil permeates the styrofoam, it is ultra-refined fish oil. A small amount of residue left in the egg cup is probably an antioxidant added to the oil, such as sesamin. Sesamin, which is derived from sesame seeds, is an excellent addition to fish oil.
Ultra-refined fish oil is very different from typical fish oils. Technically speaking, ultra-refined fish oil is a concentrate of fatty acid ethyl esters. By comparison, typical fish oils are fatty acids assembled on a triglyceride backbone. The fish oil molecules change from the triglyceride compound to the ethyl esters because toxic contaminants that are found in all fish oils are removed during the ultra-refining process. The complex refining process also significantly increases the concentration of the long-chain omega-3 fatty acids, and that’s a good thing.

There are other noticeable differences between ultra-refined fish oil and typical fish oil. First, ultra-refined fish oil flows like water; typical oil doesn’t. The increased flow of the ultra-refined fish oil improves the incorporation of the oil into the cell membranes that line the intestines.
Typical fish oils must be broken down by various enzymes before the fatty acids can be absorbed, and this can be an inefficient metabolic process in many people. On the other hand, ultra-refined fish oil can penetrate porous surfaces such as plastic, just like it enters into cell membranes. That’s why the ultra-refined oil will permeate the egg carton material.
This means you must be careful when ultra-refined fish oil comes into contact with any porous surface such as plastic or natural stone. Prolonged contact can actually penetrate the surface and cause staining. Some people mistakenly say that the fish oil is “eating through” the plastic. That’s wrong. It’s that the ultra-refined molecules are tiny enough to pass through the relatively porous material.
The Life’s Abundance fish oil products that we represent, SeaLogix Pharmaceutical Grade Fish Oils, are ultra-refined oils. The gel capsules include sesamin, an important antioxidant. Also, the gel capsules are a good choice for anyone who wants an especially easy-to-swallow version of the oil. Because of the ultra-refinement, SeaLogix has no fish taste at all.
