Omega 3 Fatty Acids

Omega 3 fatty acids have gained attention in the past few years and can aide in a variety of health related concerns. Vital to our brain development, growth and overall health, these essential fatty acids are not synthesized by the body meaning we need to have an adequate intake from our food or supplements. Nutritionally important fatty acids are ALA, EPA and DHA.

DHA and EPA are produced by micro-algae which are consumed by fish, accumulating in their organs. A vegetarian source is also available directly harvested from the micro-algae. Cold water fish containing nutritionally available omega 3 include salmon, mackerel, sardines, tuna and herring. Fish also accumulate and concentrate heavy metals so it is important to avoid certain types of fish if you are pregnant or planning to become pregnant. It is also important to verify the source of any dietary supplements to ensure they are free from heavy metals such as lead, mercury and cadmium.

Although fish contain high concentrations of omega 3 fatty acids, it is also available in plant and nut oils. Some of these seeds and nuts include soybeans, flaxseeds, pumpkin seed, walnuts and canola oil.
Omega 3 deficiencies can be associated with symptoms of dry skin, poor memory, fatigue, mood imbalance or depression and poor circulation. Infants that are not exposed to adequate doses in-utero are at increased risk of developing vision and nerve problems.

Omega 3 fatty acids are effective for reducing inflammation and reducing risk factors for heart disease, cancer and arthritis. These essential fatty acids are concentrated in the brain and are critical for behavioral function. They are also valuable for reducing the symptoms of autism spectrum disorders and attention deficit disorder.

There is an abundance of clinical evidence that demonstrates omega-3 fatty acids are helpful in reducing the risk of heart disease and conditions that play a part in heart disease. EPA and DHA stimulate circulation of the blood, increase fibrin breakdown and have been shown to lower blood pressure.

Because of their powerful ability to affect the circulatory system it is recommended that you take only the recommended dose as an overdose or very large amounts can actually increase your risk of hemorrhagic stroke. It is also important to check that the dose of omega-3 fatty acids you intend on taking will not interfere with other medicines prescribed to you.
