Ethyl DGLA is primarily used in the field of nutritional supplements and health care due to its potential anti-inflammatory and immunomodulatory properties. It serves as a precursor to important prostaglandins and other eicosanoids that regulate various physiological processes, including inflammation and immune response. This makes it valuable in managing conditions like arthritis, eczema, and other inflammatory disorders. Additionally, it is incorporated into specialized dietary formulations aimed at supporting cardiovascular health, skin health, and overall wellness. Its esterified form enhances stability and bioavailability, making it suitable for use in functional foods, capsules, and oils. Research also explores its role in supporting metabolic health and its potential benefits in managing chronic diseases.
