What is Doctor’s Best Real Enhanced Krill with DHA & EPA? Doctor’s Best Enhanced Krill with DHA and EPA is a unique dietary supplement that combines authentic Antarctic krill oil with high-potency fish omega-3 fatty acids. This combination of nutrients supports healthy brain, joint, heart, and other organ functions. The krill oil in this Doctor’s Best product is 100% krill oil from sustainably harvested Antarctic krill. Krill provides omega-3 EPA and DHA linked into phospholipids which are used as the building blocks of cell membranes. The benefits of krill oil are augmented by DHA and EPA, in the form of triglycerides, from fish oil. How does it work? Krill thrive in the frigid Antarctic seas due to their ample content of the long-chain omega-3 fatty acids DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). By remaining fluid at temperatures way below freezing, these vital lipid nutrients assist krill to routinely survive, feed and reproduce. Krill’s vital lipids also aid in the maintenance of cell membranes. Membranes are thin, interconnecting molecular sheets that define the cell’s outer border and extend into the cell interior. The membrane’s foundation, or matrix, consists mostly of phospholipids with fatty acids attached. Numerous catalytic proteins are inserted into this matrix, and these must be free to move, which requires the matrix be semi-fluid. The omega-3 phospholipids of krill oil provide a fluidizing effect to the membrane matrix, which provides the freedom of movement for numerous membrane proteins, coenzyme Q10, and other molecules to function. Why should I take Doctor’s Best Enhanced Krill with DHA & EPA? Maintaining healthy blood lipids is important not only for cardiovascular health and to help maintain memory with age. Krill oil has also been shown to elevate HDL cholesterol and supported cholesterol levels already in the normal range. DHA and EPA supports healthy heart rhythm maintenance, healthy platelet function and supports healthy blood vessel wall function. The human metabolic capacity to make these lipids is very limited, so the bulk of DHA and EPA must be obtained from our diet. The omega-3 fatty acids obtained from krill oil and fish oil are in different forms and have respectively different effects. This suggests a product containing oils from both sources would provide the unique benefits of both.
