Fish Oil

Fish oil can be thought of as one of the "best" supplements you can take, as it is relatively safe and can decrease the chances of some of the most common fatal cardiovascular disease, such as hypertension and heart attacks. The scientific evidence supports this. Although some suggest getting the same benefit by simply eating more fish, there is the possibility of ingesting too much mercury, often found in fish, which can have detrimental effects over the long term. Fish oil is helpful in the diet because it contains an important fatty nutrient; it affects the cardiovascular system in positive ways; and it may even act as a treatment for depression, although the evidence isn't as strong in this case.

Nutritional Aspects

In our typical Western diet, we consume a lot of animal fats which everyone now knows can lead to heart disease and other related disorders. But why? One recently studied phenomenon is the disparity between two types of fatty acids we consume: omega-3 and omega-6. The problem lies in the amounts of each. We consume more omega-6 than omega-3, which is problematic.

Heart Disease

Fish oil is a known blood thinner and decreases blood pressure in those with hypertension. Tied in with this is the ability of fish oil to reduce the risk of heart attack. Several studies support this, and it may be the "magic bullet," to some extent, of the answer to cardiovascular diseases that are so risky in the modern world.

There have also been some studies on the effectiveness of fish oil on depression. While this research is still inconclusive, there is evidence of its success as a treatment for bipolar disorder. Studies on depression have not been as supportive, but some users have reported good results.

Side Effects

This supplement is considered to be safe and relatively free of undesirable side effects, however, it does have one quality that should be considered before taking it. It acts as a blood thinner and should be avoided if you are taking certain drugs. It can also cause smelly breath.
