Douglas Laboratories Quell Fish Oil EPA/DHA Plus D - 30 Softgels Douglas Laboratories Quell Fish Oil EPA/DHA Plus D is Supercritical CO2 extracted oils in triglyceride form, manufactured in Germany exclusively for Douglas Laboratories. QUELL Fish Oil is unique among other fish oils for its' critical extraction, purity, bioavailability and concentrations. QUELL High EPA Fish Oil is indicated for those individuals that want the added benefit of Vitamin D3 with EPA and DHA in small, pure, and potent softgels. Critical ExtractionSupercritical CO2 advanced technology is the superior protection against oxidation. The extraction method of fish oil uses less heat and no chemical solvents when compared to molecular distillation, resulting in fewer unwanted isomer formations and cleaner oil. Critical PuritySupercritical fluid extraction uses CO2 (carbon dioxide) instead of oxygen to gently extract the fatty acids, which also protects them from microorganisms that can't survive without oxygen. No chemical preservatives, solvents, or undesirable compounds are found in QUELL Fish Oils. Heavy metal and contaminant levels measure significantly lower than the standard. Critical BioavailabilityRecent scientific data shows the triglyceride form of fish oil is better absorbed when compared to ethyl esters. Recent data have demonstrated that omega-3 fatty acids delivered in a triglyceride form may result in greater plasma levels and a higher omega-3 index compared with omega-3 fatty acids delivered in the form of ethyl esters. Critical ConcentrationMany fish oils contain only about 30% omega-3 fatty acids, of which roughly 18% is EPA and 12% DHA. The remaining 70% is a varying mixture of other components. In other words, regular fish oil contains less than a third of the desired active ingredients and more than two thirds of other components. These other components may include cholesterol, omega-6 fatty acids, saturated fatty acids, oxidation products and contaminants.
