Best Fish Oil Without Soy
Fish oil supplements from the NIH Dietary Supplement Label Database whose labels list no soy, ranked by how completely the label discloses what is in the product.
Why People Avoid Soy
Fish oil itself contains no soy, but softgels often do. Mixed tocopherols, the vitamin E antioxidant that protects the oil from oxidation, are usually extracted from soybean oil, and soy lecithin and soybean oil appear in some capsules and emulsified liquids.
Highly refined soy oil and soy-derived tocopherols carry very little soy protein, and FDA exempts highly refined oils from allergen labeling, so most people with soy allergy tolerate them. Those with severe allergy, and people who avoid soy for other reasons, still want them off the label.
Rosemary extract and sunflower-derived tocopherols are the usual substitutes. Because the filter reads every mention, a label whose allergen statement names the ingredient, even to say the product is free of it, is also dropped. The list errs toward leaving products out.

Search All Fish Oil Supplements
Open Supplement Search, choose the Fish Oil and Omega-3 tab, and turn on the "Soy" chip under Exclude products containing. This page also requires a listed other-ingredients panel, since a label without one cannot show what it leaves out, so its count runs lower than the search page's.
