How many capsules of omega 3 make 1000 mg?

I currently have a bottle of omega 3 1000 mg. I was told that a single capsule alone does not contain 1000 mg, but rather 3 capsules must be consumed to achieve 1000 mg. Is this ratio correct? The bottle says 1000 mg and suggests taking one capsule three times daily. |||A single (fish oil) capsule of 1,000 mg contains 300 mg of combined DHA and EPA (120 mg of DHA and 180 mg of EPA) so to get 1,000 mg of omega 3 (combined DHA and EPA) you need to take 3 and 1/3 capsules a day. 3 capsules a day would only give you 900 mg of omega 3 so perhaps you might want to take 4 a day to get 1,200 mg of omega 3.|||That is your answer, in the dosage. 3 capsules will give you the total of 1000 mg per day
