The thing that confuses most people about fish oil is dosing and how much to take. The label usually says something like "1000mgs per capsule" and people assume they are taking 1000mgs of the beneficial omega 3 fatty acids. This is not the case. For every 1000mg capsule there is usually only 250mgs-300mgs omega 3's. That is the only number we should be concerned with. All the studies proving the benefits of fish oil are using doses of 1200-2000mgs of the beneficial omega 3's. That comes out to 8 capsules a day for the 2000mg dose. So to get the benefits of fish oil you probably need to up your dose substantially. I take 8 caps a day broken up into 2's with my meals, not as difficult as it sounds really.
On to the study:
Omega 3 fatty acids in dietary fish oil are reported to have anti-inflammatory and anti-thrombogenic and anti-arrhythmic effects in humans, but the biochemical basis for these beneficial health effects is not well understood. Now a University of Michigan biochemist reports that fish oil significantly diminishes the production and effectiveness of various prostaglandins, naturally occurring hormone-like substances that can accentuate inflammation and thrombosis.
Dr. William L. Smith described his findings on April 4 at Experimental Biology 2006 in San Francisco. His presentation was part of the scientific program of the American Society for Biochemistry and Molecular Biology (ASBMB).
Dietary fish oil causes its prostaglandin-lowering effects through three different mechanisms, says Dr. Smith.
First, the much fewer prostaglandins are made from omega 3 fatty acids as compared to the other class of fatty acids in the body, the omega 6 family of fatty acids that originate in the diet from leafy vegetables and other plant sources.
Second, the omega 3 fatty acids compete with omega 6 fatty acids for the same binding site on the COX 1 enzyme that converts the omega 6 fatty acids to prostaglandin (which is why the COX 1 enzyme and its COX 2 cousin are the targets of anti-inflammatory drugs like ibuprofen). The more omega 3 fatty acids present to block the binding sites, the fewer omega 6 fatty acids are able to be converted to prostaglandin.
Third, although omega 3 fatty acids also are converted to prostaglandins, the prostaglandins formed from omega 3 are generally 2 to 50 times less active than those formed from the omega 6 fatty acids from dietary plants.
The biochemical basis of other benefits of dietary fish oil -- for example, omega 3 fatty acids' impact on neuronal development and visual acuity -- are probably due to effects on biochemical pathways regulating nerve transmission. Understanding the different pathways through which omega 3 works to convert prostaglandin helps explain why the plant-based omega 6 fatty acids don't simply provide the same benefits. Because of omega 3 fatty acids' known benefits to health, especially cardiovascular health, Dr. Smith's advice is simple: eat more fish.
