Fish Oil is supposed to have a high dose of Omega 3 fatty acids (FA), and be good for you, right? More is better, right? No! No, No, NO! Is Krill Oil better? Not at all!
Omega 3’s are supposed to be good for us. Yes, they are. But the fish oil supplements on the shelves of pet food stores can get oxidized quickly and deteriorate to the point where they are not only rancid, but can become neurotoxic and dangerous to any pet or person that consumes them. Oxidized Omega 3 causes a chain reaction of oxidation in you and your pet’s brain cells. I know this because I was working to develop extracted DHA oil that would guarantee a sufficiently long shelf life. Shelf life is the period that the product can be on the store shelves. Technically it is “sell by” date, but actually it is “use by” date. Products undergo thorough accelerated oxidation testing to determine their shelf life. But the test is done only on the packaged products.
Because Omega 3 FA is not stable in atmosphere, it can become oxidized easily. Fish oil naturally contains more EPA than DHA. The amounts of EPA and DHA are further concentrated, but the finished product contains large amount of EPA. Since both the EPA and DHA molecules have a high potential of oxidation, the presence of EPA more than double the oxidation potential compared to similar concentration of algal DHA which has only DHA. Manufacturers add tocopherols as antioxidants to protect the oil from such oxidation. Tocopherols are synthetic Vitamin E's. They primarily use tocopherol acetate that is a solid material that can be mixed in oil. Lots of tocopherol is required, because of the doubled or tripled oxidation site. Natural Vitamin E cannot offer enough protection from oxidation to the amount of EPA and DHA. As an anti-oxidant, the tocopherols absorb oxygen radicals, which is good, but once the tocopherols have absorbed as many of the damaging free radicals as their capacity allows, they no longer can offer any protection from oxidation to the Omega 3 molecules.
Fish Oil can reach unacceptable levels of oxidation within 90 days of use once it is exposed to air (oxigen). This can occur even if the fish oil is in use well within its shelf life period. Once seal is open, oxidation can occur quickly turning the fish oil that is supposed to be good for your pet’s health into a neurotoxin. This is true even with high quality fish oil. The higher the concentration of EPA and DHA, the higher the potential for oxidation, deterioration, and neurotoxicity become. The potential for oxidation is the same for DHA oil derived from algae, with the exception that if it only has DHA and no EPA, the total oxidizing radical it can carry into the body should be less than half the amount of fish or krill oil. Such products for humans sometimes come in oxygen barrier soft gel capsules, though this is not a perfect solution either.
SmartZYME™ is fresh whole cell DHA nutrition, brined with sterilized sea salt and added Vitamin C to protect it from oxidation, then packaged in oxygen barrier individual packets, and kept frozen; triple protection. Moreover, in addition to the DHA that your pet will gain from eating SmartZYME™, the DHA producing metabolic enzymes that SmartZYME™ contains will continue to produce DHA inside the body, totally protected from the outside air.
Fish Oil manufacturers may be spared from the blame of bad quality, or shelf life inaccuracies, but they don’t tell you what happens after opening their products. It’s your risk, not their’s. Once air enters through the pump, all the "air tight" protection is gone.
