Why this page doesn't claim "Mackerel works"
Whole foods almost never have RCTs — the evidence sits on the ingredients. So this page does one honest thing: it lists which graded ingredients Mackerel contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Mackerel itself.
Bottom line: Mackerel (saba) is a strong source of omega-3 plus vitamin B12, D, and selenium; like salmon, the evidence engine rates its omega-3 heart benefit as mixed, but B12 and the like are solid.
