I can turn this statement right around and say the same exact thing - You seldom see all the facts and data and only the snippets that support the view of those (NLS) posting the information. Where are these studies reporting that Ethoxyquin works the same way Vitamin A does? Are there studies Actual studies showing that ethoxyquin is harmless? And if so, in what amounts? And if there is an acceptable amount, why is the amount not listed on the ingredients lists?
I'll concede that Ethoxyquins effects must be either one of two things: dose is minimal. Even in the presence of tumors, and (theoretical) cancer it takes years for these symptoms to develop OR we simply don't keep our fish alive long enough for the effects to take hold. Lets face it, even among the informed few can say that Nitrate toxicity is not a factor in their fishes longevity. At the moment I'm inclined to lean towards the latter.
I'll say it again, find me a reputable unbiased source, study that proves that Ethoxyquin improves fish health.
Just so there's no misunderstanding, I am not speaking here on behalf of NLS, or any other brand of fish food.
My comments in this discussion are in defense of a product that has been safely & successfully used in animal feed since the 1960's. Fish that have lived 20, 30, some 40+ years have spent their entire life consuming this substance on a daily basis, with no known health issues.

You asked the question:
How can Ethoxyquin both "improve fish health" and be toxic at the same time?
I simply answered it, to which Tom just responded in more detail, and he was spot on in his response.
.......but as a perservative it will maintain the integrity of the nutritional value of the food itself by preventing it from breaking down on the chemical level before consumption. In that way, it can indirectly improve a fish's health.
Vitamin A works in the same way, as at approved levels it will enhance the health of a fish, at extreme levels it can kill a fish. So both can "improve fish health" and yet still be toxic.
xechox ..... making any sense to you yet?
This isn't my first rodeo when it comes to the subject of ethoxyquin, I not only keep fish, I have also owned dogs my entire life and I consider myself very well versed on this subject.
I didn't just read a blog or two on the interweb & jump to conclusions, I have actually read all of the papers & studies that are commonly referred to regarding this subject & based my decision on years of research and practical application, and a little dose of common sense.
