It seems that soy is often used as the Mixed Tocopherol Vitamin E source. I called Nature Made about it. I still use their fish oil pills since the double strength has double the EPA & DHA in each capsule. My dog hasn’t had any problem with it & I like the fact that Human Grade is more purified.
The sardines and mackeral are the source of the EPA & DHA, not vitamin E. They are actually a safer source than salmon as the mercury contamination is minimal, if any. As far as I know, sardines and mackerel are wild caught and not farmed either.
