There is much hype nowadays about fish oil dietary supplement. They can be bought for an average of 30 dollars a bottle – but is it really worth all that? As the name suggests, fish oil is taken from, well, fish. People can obtain fish oil by eating fish, especially oily fish such as sardines, salmon and tuna; they are called oily fish because they have more oil than other fish.

Anyway, some fish we eat to get the fish oil we need may sometimes be contaminated with pollutants. Because of the amount of pesticides and mercury found in most lakes and rivers, eating fish in a large quantity to gain needed amount of fish oil may be dangerous. Preferred method of receiving the required fish oil we need for omega-3 boost is through safe and highly formulated dietary supplement made from fish-oil.

Nonetheless, there is still some disagreement concerning some of the research findings; as some consumers are being advised to be cautious as the number of so called natural supplements has saturated the market. Even though there are some good and powerful herbal remedies and supplements on the market, just buying them from any source are not advisable as the danger of getting sucked into something that is unreal can outweigh the anticipated benefits of taking the supplements in the first place.

Eicosapentaenoic acid (EPA), and Docosahexaenoic acid (DHA) are the two fatty acids of debate which centers on their efficacy in cardiovascular diseases and whether they actually work or not.
