Omega-3 Factors is a pharmaceutical grade liquid fish oil concentrate providing one of the highest potencies of EPA and DHA available. Stringent quality control standards ensure this highly purified fish oil concentrate is free from toxic environmental contaminants and heavy metals like mercury.

Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease. One serving (1 teaspoon) of Omega-3 Factors provides 1500 mg of EPA and 750 mg of DHA omega-3 fatty acids.

Omega-3 Factors liquid oil has a pleasant orange flavor and is also available in softgel capsules.

Manufactured by Natural Factors to ensure safety and potency in accordance with Good Manufacturing Practices (GMP) of the FDA and Health Canada.

Wouldn't be without it
My MD introduced me to RxOmega-3 Factors and iherb about a year ago. At that time, I could not sleep through the night, was experiencing extreme mood and personality changes, a severe depression/anxiety disorder and a list of physical problems a mile long. Thanks to my doctor and iherb, I am able to lead a more normal life- and my blood pressure went down 20 points. I urge anyone who is experiencing a sleep disorder, depression, mental confusion and fatigue, please try this. A teaspoon or 2 of fish oil cannot hurt you but sleep deprivation and depression can. I think this is the best product of its kind money can buy. UPDATE: Everyone around me notices a difference if I skip a few days. I literally don't feel "happiness" at all if I stop taking this. Gelcaps just don't cut it for me, I can't digest the coating. I need the liquid. After 3 years of using this product, it's still the best.

Anti-depressant Anti-Inflamatory Pro-Cognition
The title of this critique says it all. This brand of fish oil is the strongest that I know of in this price category, the price doubles for stronger. The product is molecularly distilled to remove impurities. This is particularly important because concentrated products of the seas can also mean concentrated levels of lead, mercury and other undesirables. Read Dr. Barry Sears " The Anti-Inflamation Zone for interesting research on fish oil and its pro-health effects on our bodies and minds.
