Gamma-Linolenic Acid (GLA)

Introduction to Gamma-Linolenic Acid

Gamma-linolenic acid (GLA), an essential omega-6 fatty acid, is crucial for human health and can only be sourced from food.

Omega-6 fatty acids also referred to as polyunsaturated fatty acids (PUFAs), are vital for normal growth, brain function, skin and hair growth, bone health, metabolism regulation, and reproductive system maintenance.

Types and Sources of Omega-6 Fatty Acids

Different types of omega-6 fatty acids are predominantly derived from vegetable oils, like linoleic acid (LA). The body converts LA into GLA and subsequently into Arachidonic Acid (AA).

Plant-based oils such as Evening Primrose Oil (EPO), Borage Oil, and Black Currant Seed Oil are some sources of GLA and also contain LA.

Omega-6 Fatty Acids in Balanced Diet

A balanced diet includes both omega-3 and omega-6 fatty acids, with the former reducing inflammation and some of the latter promoting it.

The typical diet, however, contains 14 to 25 times more omega-6 than omega-3 fatty acids, contributing to inflammatory diseases in the population.

It’s important to note that not all omega-6 fatty acids promote inflammation. For instance, GLA may reduce inflammation and potentially protect DNA.

GLA supplements are typically converted in the body to DGLA, an anti-inflammatory compound, a process facilitated by sufficient levels of nutrients such as magnesium, zinc, and vitamins C, B3, and B6.

Despite the potential benefits of GLA, many experts believe the evidence for using omega-3 fatty acids to reduce inflammation and prevent diseases is stronger.
