Most people taking fish oil supplements are getting a small percentage of an optimal dose because they just take what is shown on the label of the bottle. If you are taking a food grade quality fish oil capsules you need to take anywhere from five to ten capsules of fish oil per day to achieve the most healthy dosage. <br /> <br />Pharmaceutical grade fish oil supplements such as those by Doctor's Holistic Rx contain a much higher concentration of omega 3's. You only have to take two softgels of pharmaceutical grade fish oil per day to get the most healthy dosage of omega 3's.<br />http://www.amazon.com/Doctors-Holistic-Rx-Pharmaceutical-Distillation/dp/B00KKSELFC<br />http://www.wat.tv/video/12544983
