The majority of fish oil takers are getting just a fraction of the recommended dose because they just take what is shown on the label of the bottle. With a low quality fish oil you want to take between 5-10 softgels of fish oil per day to obtain the optimal dosage.

Pharmaceutical grade fish oil supplements such as those by Doctor's Holistic Rx contain a greater percentage of omega 3's. You can take just two 1000 mg softgels of pharmaceutical grade fish oil per day to get the optimal dosage of omega 3's.
