OmegAvail™ Ultra DHA contains fish oil on its natural TG (triglyceride) form. All DFH TruTG™ fish oil products are a minimum 90% natural TG bound omega-3 oils. OmegAvail™ Ultra DHA is molecularly distilled and filtered to ensure purity and to maximize the removal of metals, pesticides, PCBs, and other contaminants. Lipase is added to engance the digestibility and mixed tocopherols (antioxidants) are added to enhance stability of the product. OmegAvail™ Ultra DHA contains highly concentrated DHA (docosahexaenoic acid) from fish oil in its natural TG (triglyceride) form. As with all Designs for Health TruTG™ fish oil products, OmegAvail™ Ultra DHA is comprised of a minimum 90% natural TG-bound omega-3 oils. Each softgel provides 500 mg DHA + 110 mg EPA for optimal DHA status. DHA is an important omega-3 fatty acid which plays an important role human physiology and is thought to have had a large impact on human evolution. DHA is not technically an essential fatty acid since the human body can synthesize very small, although insignificant, amounts of it from its short chain omega-3 precursor ALA (alpha linolenic acid). However, there is ample evidence which shows that in order to support optimal health and alleviate various pathologi­cal conditions, additional DHA along with EPA (eicosapentaenoic acid) should be obtained from diet and/or nutritional supple­ments.
