Most people taking fish oil supplements are getting just a fraction of an optimal dose because they only take what is recommended on the label of the bottle. With a low quality fish oil capsules you should take anywhere from 5-10 capsules of fish oil per day to obtain the ideal dose.

Pharmaceutical grade fish oil capsules like that from Doctor's Holistic Rx contain a greater percentage of omega 3 fats. You only have to take two capsules of pharmaceutical grade fish oil per day to get the ideal dose of omega 3 fats.
