The majority of fish oil takers are getting only a fraction of a good daily dose because they just take what is shown on the label. With a low quality fish oil supplements you need to take anywhere from five to ten softgels of fish oil per day to obtain the optimal dose.
Pharmaceutical grade fish oil supplements such as those from Doctor's Holistic Rx contain a greater percentage of omega 3 fats. You can take just two 1000 mg capsules of pharmaceutical grade fish oil per day to get the optimal dose of omega 3 fats.
