In order to find the most suitable omega 3 oils for your health, you need to have enough information about the content of these oils. Omega 3 content of oils differs because these oils are obtained from animal and plant sources.
While animal sources provide direct fatty acids, they are also rich in impurities, heavy metals like mercury, lead, arsenic and nickel, and toxic substances. Vegetable oils contain only traces of omega 3 fatty acids, with the exception of a few plants, but they are pure and have no side effects associated with their intake.
Flax seed, a very popular plant source of omega 3 fatty acids, contains around 55% of essential omega 3 content. This percentage is higher than most other vegetable oils. Some oils are not fit for consumption because of the presence of high percentages of saturated fat in them. These oils are cottonseed and coconut.
However, if you want to gain weight you can include peanut oil, walnut oil and safflower oil in your diet. The omega 3 content of these oils is also up to the required mark and they are useful for overall health.
Other sources of omega 3 fatty acids are krill oil, cod liver oil, algae oil and harp seal oil. The omega 3 content of these oils shows high percentages of essential fatty acids and very low levels of impurities. All these oils are good for the heart and help in reducing inflammation throughout the body. Cod liver oil is especially useful for children because it not only contains high amounts of DHA and EPA, but also some percentages of vitamin A and D.
Cod liver oil capsules are widely available for use and they provide protection against skin diseases and coronary heart disease. Algae oil is recommended for those who are allergic to fish and cannot take fish oil capsules.
However, fish oil is by far the richest source of DHA and EPA fatty acids. Apart from having the highest omega 3 content of oils, fish oil also contains some amount of impurities like heavy metals and toxins. Because of this reason, always find nutritional omega 3 supplements with a label indicating that the oil used for their processing is pharmaceutical grade fish oil and molecularly distilled to make it free from impurities. These refined and thoroughly tested supplement products may come a bit more expensive than other low-quality products. So, you need to be very careful in choosing your fish oil supplement.
