Fish oil contains omega 3, and the active form of vitamin A. 2000mg of fish oil is fine for the omega 3, but you'll need to keep an eye on your vitamin A intake, because too much of -that- can be dangerous. If the fish oil you're taking has less than 3000 mcg (micrograms), or 10,000 IU (international units), then you're fine, as long as you're not -also- taking a multivitamin. If you're taking both, you should probably not take one or the other.
I've been taking 2000mg of fish oil a day for a couple of years now. It only has 300mg of omega3.
Yes, fish oil caps usually only have 300 mg of omega 3 in them. The FDA says you can have up to 3000 mg, but doesn't suggest that you -should- have up to 3000mg. Only that you can consume that much safely.
My post was concerning the vitamin A content in a fish oil cap; if the vitamin A content goes over 3000mcg (micrograms - designated by mcg, not milligrams, designated by mg), then you need to make sure you're not taking too much vitamin A (possibly in the form of a multivitamin in addition to your fish oil) because you can have a toxic reaction to too much vitamin A.
I don't think anybody knows what the true consequences of consuming that much fish oil a day.......health consequences often take many years to develop.
But more importantly, why would you take 2000mg of fish oil in the first place?
Fish oil thins the blood. I could see a danger if you get a bad cut..........excessive bleeding is a possibility.
It's definitely a possibility - but it's also a possibility no matter which bloodthinners you're taking. If you have a medical need to take bloodthinners though, then that means the risk of excessive bleeding has been determined to be not as dangerous, as whatever problem you have that needs bloodthinners to treat it.
Aspirin therapy, warfarin (coumadin), fish oil - you just have to be careful and, if you're taking it for medically prescribed reasons, get your blood checked regularly to make sure it's not gone too far the other direction.
If you go to the section just above the references you'll see that it summarizes many studies with various doses (300 to 8000 mg/day) and treatment lengths and they found no reported adverse effects. Again as I believe it was mentioned before in this thread - many fish oil products also are supplemented with vitamins in which case you'll have to be wary not to overdose on those - pure fish oil in itself however appears to be well tolerated.

"he Tufts EPC reviewed 148 studies to evaluate adverse events-not including fishy aftertaste-from the use of omega-3 fatty acid supplements (typically fish oils). More than half (77) reported that no adverse events had occurred. In total, about 10,000 subjects had taken these supplements in various forms and dosages ranging from 0.3 to 8 g/day for at least one week to more than seven years. Most studies were small, with a few dozen subjects receiving supplements for less than six months."
So the long term effects are almost entirely unknown....
"The Tufts EPC concluded that adverse events related to consumption of fish-oil or ALA supplements appear to be minor and can be managed by reducing the dose or discontinuing the supplement. It noted, however, that adverse event data are incomplete because many studies did not adequately report this information, especially for subjects who withdrew before study completion."
So nobody was really tracking it...and if someone withdrew because they felt terrible and died 2 weeks later....well they wouldn't count.
So yes "No reports of adverse effects", that often happens when you're not looking for them and look at small short-term studies.
I remember the days everyone was taking vitamin E. Poor vitamin E.......has been replaced by a smelly oil.
I'm supposed to take 2000 mg of fish oil daily, one in morning and one at night.
Before surgeries I always stop taking everything, except as prescribed. Fish oil can really thin your blood.
