fish oil

There were a couple of really big, randomized studies published in Lancet recently. One showed that Lovaza (think: fish oil, only seriously cranked up) reduced overall death rates in men with cardiac disease. The other showed that Crestor did not. And, might I add, why exactly would you be taking Crestor if the goal wasn't reduced overall death rate, but hey, why go there. Maybe you work for the Alabama state government and are trying to save $25/month on health insurance (altho then I'd have to ask what your copay was looking like).

What's so special about Lovaza? Well, each capsule is kinda like 1-3+ teaspoons of cod liver oil. Assuming you bought reputable cod liver (or fish) oil, you aren't too concerned about mercury and other heavy metals anyway because they were removed. It would _appear_ to be the case that Lovaza has left the vitamin A in place (but don't hold me to that; I haven't been able to figure that out yet), and I do have to wonder about whether that's part of what they're worried about when they say you need to have your liver function monitored while on Lovaza.

Digging around a bit, I was trying to understand the whole anticoagulant issue. It seems that Lovaza really amps your platelets up, which is going to have an impact on the efficacy of aspirin/coumadin/warfarin/etc. as an anti-clotting agent. Which you might care about if you're taking that to prevent a stroke, DVT, whatever. (ETA: I think I have exactly misunderstood the concern. Apparently some fish oil preparations amp the blood thinning. I am now very confused.)

ETA2: Someone went digging for any actual evidence of clinically interesting bleeding associated with supplementing omega 3s and/or fish oil. What he found? Meh.


Still, I don't see why there was an accompanying editorial telling people not to take just any fish oil supplement, after all, this one is Special and FDA-approved and etc. Asking them to inform their health care practitioner makes sense (after all, a bunch of those same issues would seem to apply to any fish oil supplementation).

I am kinda wondering if this is why my midwife was surprised at how good my platelet count was looking in the third trimester blood draw (after all, it's pretty normal through dilution to be somewhat anemic at this point, among other things). I did _tell_ them I was supplementing fish oil. I'm not sure any of us realized it might have this effect. Then again, Odent keeps going on and on about sea-food and fish oil and fatty acids while in the same breath (or at least the next paragraph) talking about how it is physiologically normal/correct/good to have lower hematocrit/platelet count/anemia/wtf late in pregnancy. *shrug*

ETA4: Oh, never mind. No connection that I can determine.

At this point, between the magnesium revelations and the fatty acids, I'm just about ready to roll off the couch laughing. Hoocoodanode? Cod liver oil and milk of magnesia. What next from the medicine cabinet of the late 19th/early 20th century? Calamine lotion? Kaolin?

As long as we can avoid all the purgatives, I'm willing to entertain just about anything at this point.
