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 low quality fish oil you need to take between five to ten capsules of fish oil per day to obtain the most healthy amount.

Pharmaceutical grade fish oil products like that from Doctor's Holistic Rx contain a higher amount of omega 3 fats. You only have to take two softgels of pharmaceutical grade fish oil per day to get the most healthy amount of omega 3 fats.
