Alpha omega 3 is the name sometimes given to omega 3 fatty acids or polyunsaturated fatty acids because they contain an important fat known as alpha-linoleic acid or ALA. Other acids are DHA and EPA which are primarily obtained from fish oil.

Flax seed oil is a rich source of alpha omega 3. It contains ALA in large quantities. Since ALA is a long-chain fatty acid, it needs to break down into short-chain fatty acids or DHA and EPA to be used by the bloodstream. To obtain DHA and EPA directly, fish and fish oil supplements are recommended which are very beneficial for long-term health.

Good quality fish oil capsules provide up to 300-400 mg of both DHA and EPA combined. 3 to 4 capsules are recommended to an average, healthy person on a daily basis. Children and elderly people can be given liquid fish oil supplements which are pure and cause no side effects of any kind.

Alpha omega 3 fatty acids are good for people of all ages. They are required by pregnant and lactating women, children in their growing age and teenage, middle aged persons for the prevention of heart disease and elderly people for the cure of degenerative diseases like arthritis and Alzheimer's disease.

DHA is particularly important for improving memory and preventing psychological conditions like depression and anxiety. Intake of large quantities of omega 3 fatty acids has a significant impact on changing personality and behavior of an individual. People who have frequent mood swings and a short temper are considered DHA deficient. These people should immediately start consuming fish oil capsules.

Only fatty fish are used for extracting oil and manufacturing fish oil capsules. These fish include salmon, herring, mackerel, hoki and sardines. The oil of these fish may contain impurities, contaminants and toxins from the ocean. To clean this oil, a process known as molecular distillation is employed which filters and refines the oil and makes it fit for consumption.

This oil is commonly known as pharmaceutical grade fish oil. The oil of hoki fish found in New Zealand is also recommended by health specialists as it has been found that waters around New Zealand are less polluted and contain less contaminants and heavy metals than other parts of the world.

It is also advisable to eat a well-balanced diet along with nutritional supplements to ensure proper health and a strong immune system to fight against all types of diseases.
