NOW Ultra Omega-3 

Helps maintain cardiovascular health and cognitive function. Helps to reduce serum triglycerides and triacylglycerols. Helps support the development of the brain, eyes and nerves in children 18 years and younger. There are many Omega-3 fish oil supplements, but there is only one Ultra Omega-3 from NOW Foods. This product is among the highest potency fish oil concentrates available, providing more than twice the amount of EPA and DHA of a regular 1000 mg fish oil softgel. The Fish Oil Concentrate used in this softgel is manufactured under strict quality control standards. It is tested to be free of potentially harmful levels of contaminants (i.e. mercury, heavy metals, PCB's, dioxins, etc.). Those who experience nausea or reflux from other fish oils should find this enteric coated, odour-controlled softgel easier to tolerate.

Omega-3 fatty acids from fish oils have anti-inflammatory and antithrombotic effects because they compete with arachidonic acid in the cyclooxygenase and lipoxygenase pathways. Fish oils inhibit the arachidonic acid synthesis of thromboxane A2, which causes platelet aggregation and vasoconstriction. Fish oils can also cause increased production of prostacyclin, a prostaglandin that reduces platelet aggregation. Omega-3 fatty acids seem to suppress COX-2 expression and the inflammatory cytokines interleukin (IL)-1 alpha and tumor necrosis factor (TNF)-alpha. Fish oils are used for cardiovascular conditions, including stroke and heart disease, due to their anti-inflammatory and antithrombotic effects. EPA and DHA are mainly found in the phospholipid components of the cell membranes. DHA is taken up by the brain in preference to other fatty acids. DHA appears to be a major determinant of membrane fluidity in brain cells, influencing neurotransmission and prostaglandin formation that are vital in the maintenance of normal brain function, including cognition and mood. DHA is vital for normal brain development for the fetus and infant and for the maintenance of normal brain function throughout life.
