How much omega-3 fish oil supplements should we take?

 Look at the label.  The amount of fish oil is not the important number - it is the amount of EPA and DHA, the protective onmega-3 fats.  What you are interested in is the amount of EPA and DHA per serving.  Add up the amount of EPA + DHA and figure our how many capsules you will have to take to come up with at least 1000 mg per day.
If you take a pharmaceutical-grade (at least 60% DHA + EPA) omega-3 fish oil supplement, the suggested dose is about 1500-2000 mg daily. If you buy standard fish oil (which is about 30% omega-3 by weight) from a pharmacy or discount center like Costco, you will need to take 3-6 capsules (1000mg each) daily.
