Dose of Omega 3 Fish Oil



Hi there,

I have noticed that there are several manufacturer of Fish Oil Omega 3. What is the exact dose of omega 3?

Some manufacturers recommend 1 capsule three time daily (Kirkland), other recommend 2 capsules a day and some 5 to 6 capsules a day. Is this the real dose or just the dose the manufacturer tries to sell to customer so that their product is sold fast?


The major issue with fish oil products is that most are considered dietary supplements and are therefore not regulated by the Food and Drug Administration. The exact strength and content of each product may vary from manufacturer to manufacturer.

There is one product, Lovaza, which is FDA-approved. Clinical studies have been performed on this particular formulation that have established the optimum dose. The manufacturer must also comply with strict industry standards as far as the strength and content of the product. Lovaza is only available by prescription, and is dosed 4 grams per day (either as a single dose or as 2 grams twice-daily). This product is only approved for treatment of high triglycerides. The manufacturer has not established dosing for other potential indications.
