According to James Scala, author of The New Eating Right for a Bad Gut, you need at least 2 grams of EPA a day. Five grams is better and up to 9 grams a day is safe. That's GRAMS, not milligrams. He also recommends 1 gram of GLA (evening primrose or borage oil) a day. If you check the nutrition panel, you may find you're not taking nearly enough. Only the high quality, expensive brands that are "max" dosage are going to get you where you need to be.

Regarding flavors, I've seen fish oil and fish oil caps in lemon, orange and mint flavors as well as strawberry.
