F -- Strong scientific evidence against this use (it likely does not work)
I will include those with A and B ratings according to the Mayo Clinic as I consider these significant.
Based on proper dosage, omega-3 fatty acids from fish or fish oil supplements (EPA, DHA) significantly reduce blood triglyceride levels.
Fish oil supplements also appear to cause small improvements in high-density lipoprotein (good cholesterol).
Secondary cardiovascular disease prevention for those with a history of heart attack. Fish oil reduces the risk of nonfatal heart attack, fatal heart attack, sudden death and death due to any cause. The cardiac patients used in these studies were also using conventional heart drugs, suggesting that fish oil might enhance the effects of other therapies.
Large epidemiologic studies report primary cardiovascular disease prevention and a significantly lower rate of death from heart disease for men and women who eat fish regularly. (Note: For these benefits to occur, fish must be prepared healthfully. Frying fish negates the benefits.) Generally, evidence suggests the same benefits from taking fish oil supplements.
Protection from cyclosporine toxicity in organ transplant patients. Heart and kidney transplant patients who were given fish oil supplements along with conventional medicine reported less incidence of hypertension and greater kidney function compared to those not taking fish oil.
Those with rheumatoid arthritis taking fish oil showed decreased morning stiffness and joint tenderness for up to three months.
We can also get enough fish oil by eating fish, but most of us don't eat fish as often as we need it. Fish such as mackerel, catfish, pollock, herring, trout, sardines, tuna and salmon are considered good fish because they are not at the top of the food chain. Predator fish such as shark, swordfish, king mackerel, and tilefish have a greater chance of having higher levels of environmental contamination.
