- BEST ABSORPTION RESULTS AND FLAVOR - Our fish oil concentrates come in the triglyceride molecular form, which is naturally found in fish. Unlike other brands that use a synthetic fat, ethyl ester, our triglyceride formula ensures optimal absorption. Your kids will also love the natural strawberry flavor. No fishy smell, taste, or aftertaste! Nordic Naturals is a leader in freshness using natural essence in our patented flavoring process.
