Most fish oil consumers are getting a small percentage of the recommended dose because they just take what is indicated on the label. If you are taking a low quality fish oil you need to take between five to ten softgels of fish oil every day to get the most healthy dose.
Pharmaceutical grade fish oil capsules such as those from Doctor's Holistic Rx contain a greater percentage of omega 3 fats. You can take just 2 capsules of pharmaceutical grade fish oil every day to get the most healthy dose of omega 3 fats.
