How much fish oil should you take?

According to Dr. Andrew Weil, when using fish oil supplements, have a daily intake of 700 to 1,000 milligrams of EPA and 200 to 500 milligrams of DHA in the smallest number of pills possible. For liquid supplements, aim for the same amounts of these critical omega-3 fatty acids.

Because both EPA and DHA amounts in different fish oil supplements vary, reading the labels is important to ensure proper dosing, according Dr. Weil. Looking for supplements that are independently tested and guaranteed to be free of heavy metal contamination is also key when selecting which fish oil supplements to purchase.
