Nordic Naturals

An omega-3 specialist range — fish, cod liver and algae oils — with a notably large children's and infant selection, in softgels, liquids and gummies.

The number that matters on every product here is combined EPA and DHA per serving, not the total oil weight, and it is printed on each panel. The algae products are the plant-based route and are the ones to choose on a vegan diet. The children's range is the other reason people come to this brand: it is dosed differently from the adult products and comes as liquids and gummy chews rather than large softgels, so follow the pack directions for age rather than scaling an adult serving down. See omega 3 & oils to compare with other brands, and gummies for chewables generally.
