Ultra pure fish oil will be free of mercury, dioxins and PCBs. High levels of oxidation, which indicate that the oils were allowed to spoil before being encapsulated, will not be present, because that increases your intake of free radicals. A cause of cellular aging, that’s not something that we want more of in our bodies.
But, how can you be certain about the purity of a supplement?
The better manufacturers are able to prove purity with an independent certificate of analysis or COA. The internet makes it easy for consumers to compare the quality of everything that they buy. Most supplement manufacturers realize the value of a good website. On it, they include valuable information that is easy to verify.
A COA is one of the things that they can and should include on their websites. It will list mercury, dioxins, PCBs and oxidation levels. If it is ultra pure fish oil, none of the contaminants will be detected. The level of oxidation will be lower than 17 and the anisidine value will be below 12. Not all manufacturers list both, but the best ones do.
A COA will provide other important information, as well. The omega-3 content will be listed.
Most of the fish oil capsules on the market contain 1000mg or 1 gram of fat. Of that fat, part of it is omega-3 fat, part is omega-6 fat and part is omega-9 fat. The largest part should be omega-3s, but that is not always the case. In the better brands, at least 500mg is omega-3 fat.
The COA will also list the content of a specific omega-3 called DHA or Docosahexaenoic acid, which of all the omega-3s, appears to be the most important to human health. A gram of ultra pure fish oil should provide a minimum of 280mg of DHA, because:
• Low blood levels are associated with depression
• Supplementation reduces blood triglycerides and increases levels of “good” HDL cholesterol
• The brain and eyes contain a great deal of it
• The only dietary sources are fatty fish and marine algae (which people don’t eat), so most of us don’t get enough of it
The COA will also list the content of EPA or Eicosapentaenoic acid, which has been the subject of more studies than DHA. A gram of ultra pure fish oil should provide a minimum of 120mg, because:
• Low blood levels are associated with suicidal behavior and schizophrenia
• Supplementation reduces the risk of heart attack, stroke, diabetic neuropathy and varicose veins by improving circulation and reducing the risk of blood clots
• The only dietary sources are fatty fish and marine algae
So, a COA allows you to be certain about the purity of a supplement, as well as the nutritional value.
If you choose a good supplement, there are benefits to the heart, brain, joints, skin, eyes and every cell of the body.
Ultra pure fish oil might even reduce your risk of certain types of cancer. Buy some, today.
