Patient Education

Omega-6 Fatty Acids


What is it? Omega-6 fatty acids are types of fats. Some types are found in vegetable oils, including corn, evening primrose seed, safflower, and soybean oils. Other types of omega-6 fatty acids are found in black currant seed, borage seed, and evening primrose oils.

Omega-6 fatty acids are used for many conditions, but so far, the best information that science can provide is that putting arachidonic acid, a particular omega-6 fatty acid, in infant formula doesn't improve infant development. Not enough research has been done on omega-6 fatty acids to judge whether or not they are effective for other uses.

Most of the information we have on omega-6 fatty acid supplements comes from studying specific omega-6 fatty acids or plant oils containing omega-6 fatty acids. See the separate listings for gamma linolenic acid, as well as evening primrose, borage, and black currant.
