Do omega-3 fatty acids affect your cholesterol?

Yes, many. They tend to have little effect or a slight increase on the bad cholesterol (ldl), they increase your good cholesterol (HDL) by about 9% and their main effect is to lower your triglycerides which they do around 45%.
Yes. Omega-3 fatty acids can have a mild effect on both LDL and HDL as well as a sometimes profound effect on triglycerides when used at certain doses. Most experts feel the beneficial effects of omega-3s go beyond its effect on cholesterol. Unfortunately the research on omega-3s to date has been underwhelming due to poor study design.

Does the intake of omega-3 fatty acids help lower cholesterol?

Yes and no. They are really better at lowering triglycerides than lowering cholesterol, but lowering high triglycerides may slightly raise the HDL cholesterol and therefore improve the ratio slightly. Read more...
Not really. It generally has a small effect on cholesterol. At high doses like 2000 mg a day it can lower another type of fat called triglycerides. Read more...

Do omega-3 fatty acids affect blood lipoproteins?

Several actions. Omege 3 fish oils are most helpful in lowering triglycerides, some people have genetically high triglycerides, and they can also be high for people who are diabetic. Triglycerides are a different type of fat than cholesterol, that is an independent risk for heart problems, and possibly pancreatitis if they are really high. Fish oil can dramatically reduce them, and may also mildly lower your ldl. Read more...
Many ways. At common doses (1g epa/dha) of fish oil there are not major changes in lipids/lipoproteins. However, at higher doses (2-4g epa/dha), tirglycerides may be decreased by 30-50% and while ldl-c may staty the same or increase, LDL particle number (ldl-p) stays the same or decreases. Read more...
FishOils Lower Trigs. Omega3 fatty acids at high doses (2-4 gms/day) do lower tg's, but are most effective when the tg'sare elevated >500mg/dl. At this level they can lower tg's up to 45%. The effect is seen with fish based omega3's (epa & dha) not plant based (eg. Flax seed oil). There is a dose response seen. For each gram of 03's, about 10% additional reduction in triglycerides. Fish burp can be a side effect. Read more...
EPA Best Evidence. Both epa ; dha, from phytoplankton, at very high (i.e. Purified rx) doses, tend to ? the triglyceride concentrations in blood. Epa (without dha ; all the other non-beneficial fats in common fish oil) has a track record of also ?ing LDL particle number, even at lower doses, thus i commonly recommend purified epa. Even more effective for ?ing triglycerides is greatly ?ing all carb foods ; ?obesity. Read more...

Can you overdose on omega 3 fatty acids?

Yes. They contain vitamin a, d, and e and large amounts can result in toxicity from these vitamins. Also, as they are anti-coagulants, high doses can cause bleeding and even hemorrhage. Too much of anything usually becomes a bad thing. Read more...

What are some foods that contain omega 3 fatty acids?

Many. Fish is one of the most well known: such as salmon, tuna, sardines, and halibut; other seafood including algae and krill; some plants like brussels sprouts, kale, spinach, and salad greens ; flax seeds; and walnuts. Some people's systems are not efficient at converting alpha-linolenic acid (ala) from plant-based omega-3's to epa and dha that are needed; for these, fish or krill oil may be better. Read more...

What is the definition or description of: omega-3 fatty acids?

Biochemistry. Omega-3 fatty acids are labelled as such because of the chemical makeup. It's a carbon based structure with double bonds (therefore it's an unsaturated fatty acid). The '3' comes from the fact that the first double bond is located after the 3rd carbon from the 'omega' end (which is the end without the acid -cooh). So bottom line is it gets its name from its biochemical makeup. Read more...
