How much fish oil should I take daily? I'm taking GNC Fish Oil 1000mg, 2 capsules a day. That gives me 360mg of EPA and 240mg of DHA daily. I've read in this forum that many people take up to 4000mg, 5000mg of fish oil a day, but that sounded an awful lot to me. So, how much do you guys take? What's the "RDA" (since there's no official one)?
