Stearidonic acid, also known as moroctic acid, is primarily used in the nutraceutical and pharmaceutical industries due to its health benefits. It is a precursor to long-chain omega-3 fatty acids, such as EPA and DHA, which are essential for cardiovascular health, reducing inflammation, and supporting brain function. In dietary supplements, it is often included to enhance omega-3 intake, especially for individuals who do not consume enough fish or seafood. Additionally, it is being studied for its potential in managing conditions like arthritis, skin disorders, and metabolic syndrome. In the cosmetic industry, it is utilized for its anti-inflammatory and skin-soothing properties, making it a valuable ingredient in skincare products aimed at improving skin hydration and elasticity.
