Fish Oil Delivery – Triglycerides vs. Ethyl Esters
While the amount of EPA, DHA and DPA provided in a fish oil product is important for efficacy, the type of fish oil delivered is another significant factor in defining fish oil effectiveness. The human body is accustomed to digesting and absorbing EPA, DHA and DPA in the triglyceride form. Even though triglyceride-based fish oils are the preferred form for superior fish oil absorption, the vast majority of fish oil products available on the market are in the ethyl ester form. While ethyl esters allow for higher concentrations of EPA and DHA to be achieved, their unusual structure is resistant to the digestive enzymes (lipases) that enable fat breakdown.
DPA collects in a variety of tissues including the liver, breast, brain, eyes, heart and red blood cells and is the intermediate between EPA and DPA. This, combined with the retroconversion of DHA back to EPA, suggests that DPA may be a reservoir for both EPA and DHA, thus increasing the storage of EPA, DHA and DPA and in turn, the beneficial healthy effects, of omega-3 fatty acids. The roles associated with DHA and EPA in supporting metabolic processes, neurological development, and maintaining inflammatory balance may, in part, be attributed to DPA.
Cardiovascular and Blood Sugar Health
Omega-3 fatty acids have long been known to benefit cardiovascular health. Studies have shown that for each gram of omega-3s consumed, there was improved support for healthy blood pressure levels already within the normal range.
Additional Benefits of Omega-3 Fatty Acids
In addition to their well-known cardiovascular benefits, omega-3 fatty acids play a central role in brain development, mood enhancement, improved cognition, joint comfort and visual acuity.
