Omega-6 fatty acids are polyunsaturated fatty acids that perform essential functions in the human body. The most abundant member of this family in food and in the body is linoleic acid. Other members include gamma-linolenic acid and arachidonic acid. Linoleic acid is considered an essential fatty acid since it cannot be synthesized by the body. However, other members of the omega-6 family can be made from linoleic acid.

Omega-6 fatty acids have numerous important roles in the body.1 They contribute to the structure and function of cell membranes and play a part in the regulation of gene activity inside the cell. Arachidonic acid is especially abundant in the brain, and may be important for normal brain development of the fetus and infant. Both arachidonic acid and gamma-linolenic acid can be converted to prostaglandins and related substances that affect inflammation, blood clotting, smooth muscle tone, and many other body activities.

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
