You can get pure omega 3 oil from fish oil capsules. However, there are a few important points to consider:
* The quality of the omega 3 oils depend on the type of fish, where it is coming from. Some of the best sources for omega 3 (DHA and EPA) are salmon, mackerel and herring. Make sure, when you buy pure fish oil that it comes from these sources.
* Due to the heavy pollutions of the oceans with heavy metals and other toxins, fish might no longer be the ideal dietary supplement. So, whenever you buy fish oil, make sure it is molecularly distilled. This means that the fish oil went through a purification process where all possible contaminants have been removed.
* Fish oil is very susceptible to rancidity and that's why many fish oil products use substances to prevent the oil from getting rancid. Ideally you should by fish oil which contains only a little bit of vitamin E and nothing else - otherwise it's not pure fish oil.
This information should help you to choose high quality pure omega 3 fish oil, which is free from toxins and pesticides and which contains a high concentration of EPA and DHA - the two most important sources of omega 3 fatty acids.
