Claim #1: Fish oil raises LDL
Counter:

Fish oil attenuates the cholesterol induced rise in lipoprotein cholesterol

Suppression by diets rich in fish oil of very low density lipoprotein production in man.
P J Nestel, W E Connor, M F Reardon, S Connor, S Wong, and R Boston

Comment: One study I encountered showed an increase of 2.5% over a one year period. Many believe the affect on LDL is inconclusive. However, we should recall that while LDL is one marker, a more significant one in triglyceride level, which has been consistantly shown to be reduced by fish oil.

Claim #2: Decreases immune function
Counter: Modulation of postoperative immune response by enteral nutrition with a diet enriched with arginine, RNA, and omega-3 fatty acids in patients with upper gastrointestinal cancer.
Senkal M, Kemen M, Homann HH, Eickhoff U, Baier J, Zumtobel V.

Dietary omega-3 polyunsaturated fatty acids plus vitamin E restore immunodeficiency and prolong survival for severely ill patients with generalized malignancy

Comments: This claim holds no water when looking to the available research.

Claim #3: Toxic Vitamin A and D

Counter:

Evidence of a role for retinoic acid (vitamin A-acid) in the maintenance of testosterone production in male rats.

Benefits and requirements of vitamin D for optimal health: a review
WB Grant, MF Holick

Comments: While only applying to Cod liver oil, this claim is so false it drove me half mad. Vitamin A and D CAN be toxic, but it takes more than some cod liver oil to do it. While staying under toxic doses, they have a myriad of benefits, including ones directly applying to bodybuilding/ weightlifting (see the top of my counter).

So, are you happy? Is this enough to counter your un-cited excerpt of a book? I hope this clears fish oil from these unfounded allegations.

even before this I found this to be true… for me. Thins the blood, you’ll bleed longer if you have a cut and as another thread said you will bruise easily. I guess it’s just proof that megadosing (even though Iw asn’t taking half of what many take) on anything could be a bad thing. The overall health benefits far outweigh the negative, but if you have a sport/hobby/work were scrapes or bruises are common you may want to ease up on the fish oil.

Studies are often performed with a goal, so they dont’ look for all the side effects. Thinning the blood similar to aspirin might help stroke victims, but can have a different effect when considering endurance performance. Through some method it definitely eases tendonitis, and arthritis, but not having pain there can keep you from correcting whatever issue causes the pain.

it’s good to rethink this stuff from time to time. i take your dosing 2-3x/day. no problems! and really getting what i wanted wich was a quickness to my recovery while noticing a side effect of mood enhancement.

like you, i did take pause when a few years ago i read that the AHA recommended no more than 3g/d due to the potential for reduced platelet aggregation. but i have found no problems with bruising or bleeding. actually noticed that it put a halt to the little cherries (cherry angiomas) i was getting here and there. maybe just a coincidence.

if you are worried about supplementation, load up on pacific salmon, grass fed beef, and those little fishies (sardines and halibut).
