Bruising easily = Too much fish oil?
Original post in this thread

I haven't had a bruise like the one I have in a really long time. I recently changed the brand of fish oil I use (Nordic Naturals) and I was taking more than the recommended dose based on some info I've read.
Is this a coincidence or could it be from too high of a dose?
What should the ideal dose be? I'm 5'9'', 180lbs and muscular/lean.

It's possible.

This antithrombotic potential of fish oil, rich in (n-3) polyunsaturated fatty acids (PUFA), has been attributed to a reduction in platelet activation, a lowering of plasma triglycerides and (vitamin K–dependent) coagulation factors and/or a decrease in vascular tone. Most intervention studies have shown only moderate effects of (n-3) PUFA on these hemostatic variables. On the other hand, the usually small prolongation in bleeding time with fish oil does not appear to lead to bruising or hemorrhage, at least in healthy subjects.
So it's not a huge risk, but the mechanism is there. Try lowering your dose.
