Overview

Omega-6 fatty acids are a type of polyunsaturated fat that is essential for human health, meaning the body cannot produce them and they must be obtained from the diet. The most common omega-6 fatty acid is linoleic acid (LA), which can be converted to other omega-6 fatty acids, such as arachidonic acid (AA). Omega-6 fatty acids play a role in a variety of bodily functions, including brain function, skin and hair growth, and bone health. They are also involved in the inflammatory response. While some inflammation is necessary for the body to heal, chronic inflammation is associated with a number of diseases. The modern Western diet tends to be high in omega-6 fatty acids and low in omega-3 fatty acids, which can lead to an imbalanced ratio of these two types of fats. This imbalance is believed to contribute to chronic inflammation and other health problems. Therefore, it is important to consume a balanced ratio of omega-6 to omega-3 fatty acids.

Key Benefits

Supports Brain Function

Omega-6 fatty acids are important for brain development and function.

Promotes Healthy Skin and Hair

They are involved in maintaining the structure and function of the skin and hair.

Regulates Inflammation

Omega-6 fatty acids are precursors to molecules that are involved in the inflammatory response.

Dosage & How to Take

There is no specific recommended dose for omega-6 fatty acids, as they are abundant in the diet. The focus should be on achieving a healthy ratio of omega-6 to omega-3 fatty acids.

PurposeDoseNotes
General healthA ratio of 4:1 or lower (omega-6 to omega-3) is often recommended.This can be achieved by reducing intake of processed foods and increasing intake of omega-3-rich foods.
