Most people taking fish oil supplements get just a fraction of the recommended dose because they only take what is recommended on the label of the bottle. When taking a low quality fish oil supplements you need to take anywhere from five to ten capsules of fish oil daily to get the recommended dosage.
Pharmaceutical grade fish oil products like that from Doctor's Holistic Rx contain a much higher concentration of omega 3's. You only have to take two 1000 mg capsules of pharmaceutical grade fish oil daily to get the recommended dosage of omega 3's.
