The majority of fish oil takers are getting only a fraction of an optimal dose because they do what is indicated on the label of the bottle. If you are taking a food grade quality fish oil capsules you should take between five to ten capsules of fish oil on a daily basis to get the ideal amount.
Pharmaceutical grade fish oil products such as those by Doctor's Holistic Rx contain a greater percentage of omega 3's. You can take just 2 softgels of pharmaceutical grade fish oil on a daily basis to get the ideal amount of omega 3's.
