Too much fish oil?

What would the signs be that someone is taking too much fish oil?

When I first went Paleo I took quite a bit while I was trying to get my omega balance in order. I have scaled my daily dose back drastically - but still - I wonder if I needed to be taking as much as I am. Even better would be that I could stop taking it altogether.

what about EPA from sardines and Salmon? is this only a concern with fish oil supplements?

No, I have never had my omega ratio tested. Do you mean with a lab test of some sort? I'm more interested in practical day-to-day signs to watch for.

Signs would probably be from too much EPA interfering with arachidonic acid metabolism. See Chris Masterjohn's recent article:

"Providing sufficient DHA to allow the synthesis of the full spectrum of inflammation-resolving compounds is a nutritional approach to inflammation. Providing high doses of EPA that interfere with arachidonic acid metabolism, however, is a pharmacological approach, and it is likely to have many adverse consequences."

"Arachidonic Acid Deficiency ??? Dry, scaly, and itching skin ??? Hair loss ??? Dandruff ??? Reproductive difficulties in both males and females ??? Gastrointestinal disturbances ??? Food intolerances ??? Kidney disease ??? Inability to maintain weight ??? Poor immunity ??? Poor growth ??? Inflammation"

"Non-steroidal anti-inflammatory drugs (NSAIDs) work their magic by interfering with the production of PGE2 from arachidonic acid, a characteristic they share with EPA. One of the most common set of side effects associated with these drugs is gastrointestinal disturbances. Four out of ten users of NSAIDs experience symptoms such as heartburn, acid reflux, stomach burning, nausea, or bloating.56 Researchers have used NSAIDs to produce food intolerances in mice that result in a form of severe intestinal damage called villous atrophy that is usually associated with celiac disease,57 suggesting that a deficiency of arachidonic acid or the PGE2 made from it may underlie celiac disease and other food intolerances, perhaps by preventing the gut from forming cellular junctions and thus impairing its integrity. Excessive doses of EPA from fatty fish, fish oil and cod liver oil may contribute to all of these symptoms in susceptible individuals."

"The same conditions that reduce the requirement for arachidonic acid and DHA are likely to increase a person???s tolerance for EPA. A diet that excludes refined sugar and rancid vegetable oil, is low in total PUFA content, is adequate in protein and total energy, and is rich in vitamin B6, biotin, calcium, magnesium, and fresh, whole foods abundant in natural antioxidants should not carry any risk of arachidonic acid deficiency when moderate amounts of EPA are consumed. Liberal amounts of egg yolks and liver providing preformed arachidonic acid would provide extra insurance against damage by EPA."

They saw the GI and skin side effects in the EPA 1.8 g/d JELIS study (see table 4)

If you're going to use fish oil, I would use one with more DHA than EPA like this one.

Your biggest concern should be your proper 6:3 ratio, with the 6 preferably low. I'd say lower your 6 before I would ever say get more 3! Do you know your 6 to 3 ratio?

Read Dr Davis http://heartscanblog.blogspot.com/ regarding fish oil. You need to scroll down a few postings to see two regarding what fish oil does and why we all should take fish oil and which he feels are the best.

On his site there is a link to ZRT labs for testing Omega6 to Omega3 ratio.
