Omega-3 and omega-6 fatty acids are important components in cell membranes and precursors of many substances in the body, such as those involved in the regulation of blood pressure and the body's inflammatory response.

There is evidence that omega-3 fatty acids help protect against cardiovascular diseases and are known for their anti-inflammatory actions, which play a significant role in many conditions.

There is a growing interest in the role of omega-3 fatty acids in the prevention of diabetes and certain types of cancer.

The human body is capable of producing all the fatty acids it needs, except for two: linoleic acid (LA), an omega-6 fatty acid, and alpha-linolenic acid (ALA), an omega-3 fatty acid. These must be obtained through the diet and are therefore called "essential fatty acids." Both are necessary for the growth and repair of the body and are also used for the synthesis of other fatty acids.
