At Atlas Nutraceuticals we only use the finest quality menhaden fish oil. Our formula is packed with DHA, EPA and what researchers call the "missing omega"....DPA!!! Let us explain this wonderful discovery for you! DPA menhaden fish oil is derived from a species of fish called menhaden. Menhaden are found in the Atlantic and Gulf of Mexico as well as in some parts of the Pacific Ocean. The fish is rich in omega-3 fatty acids, including EPA, DHA, and DPA. DPA menhaden fish oil is a concentrated form of DPA, which is why it is becoming increasingly popular. The primary difference between DPA and EPA and DHA is the way it is metabolized in the body. DPA is metabolized differently than EPA and DHA, which means it may be more readily absorbed by the body. This means that a smaller dose of DPA menhaden fish oil may be more effective than a larger dose of EPA and DHA.
