The short answer is that it is probably your fish oil capsule or the source of your fish oil. Not all fish oil is made the same. I use a no repeat fish oil. The long answer - please read all for the complete answer. Remove Fish Oil Repeat Problems People often complain about fish oil repeat in reviews and online forums. People have various suggestions about how to get rid of that fishy burp back. Suggestions include storing them in the freezer, taking the capsules before meals and taking it along with a calcium supplement. But, here you will learn about what causes fish oil repeat and how you can avoid it entirely. There are hundreds of different brands on the market. It seems like more companies form every day. Its not surprising when you realize that this is the best selling nutritional supplement on the market. Everybody wants a piece of the pie. Some companies guarantee that their supplements will not cause fishy burp back. How can they guarantee such a thing? The cause of fish oil repeat is highly oxidized oil. Oxidation or spoilage begins as soon as the catch is landed. If the catch is handled properly, very little oxidation occurs. If it is allowed to lie on the dock in the sun for hours at a time, lots of oxidation will occur and the supplement will cause fishy burp back. The amount of oxidation allowed by government agencies is very high. For example, the standards set by the US Food and Drug Administration are so high that they are basically irrelevant. The same is true of their standards for contaminants. Many people buy supplements thinking that they are evaluated by the FDA, but thats simply not true. The FDAs major concern is that companies do not make claims concerning the treatment of a disease. In order to prevent fishy burp back, manufacturers should have the level of oxidation tested before the oils are encapsulated. Once they are encapsulated, no further oxidation will occur, as long as a small amount of vitamin E is included. If the total level of oxidation is below 17 MEQ/KG, then there will be no fish oil repeat. If it is above that level, then the batch should be discarded, but most manufacturers would not consider such a thing. It would be like throwing away money. Some manufactures add lemon or other artificial flavorings to reduce burping, but what most people notice is that they still have the burps. It just tastes more like lemons than fish. An added flavoring or fragrance can only mask the taste and smell of oxidized or rancid oils. The biggest risk of taking rancid oils is due to the free radicals that they contain. Free radicals are damaging to the cells of the body. They contribute to aging and age-related diseases. Our goal should be to increase our antioxidant status, in order to fight free radical damage and reduce our risks of those diseases. In other words, fishy burp back is not life-threatening, but free radicals can be. If youre smart, you will only buy from a manufacture that guarantees to provide a burp-free product. They should also reveal the amount of oxidation present, as determined by an independent laboratory. You dont have to settle for fish oil repeat. It isnt really caused by the supplement. And now, see this website for more information on a fish oil that is guaranteed to have NO fishy burp back, no fish oil repeat. They can tell you much more than I can but the above is what I found interesting and their fish oil works for me. Hope this helps. Larry"
