Triple Maxi Omega 3 Concentrate with D3 is enteric-coated. Enteric coating is a barrier applied to a capsule that protects from the breakdown in the acidic environment of the stomach, but will breakdown rapidly in the alkaline environment of the small intestines. What this means to you is that more EPA/DHA gets absorbed into your system with no fishy aftertaste, breath, or gastrointestinal discomfort. Triple Maxi Omega 3 Concentrate with D3 (1000 IU per serving) is one of our two most potent omega-3 formulas and it allows you to get the healthy support of your vitamin D3 requirements at the same time. How convenient!
