Plant seed oils are popular supplements that provide omega-3 and omega-6 fatty acids. Flaxseed oil is rich in the omega-3 fatty acid ALA (alpha-linoleic acid). Black currant, borage, and evening primrose oils are good sources of the omega-6 fatty acid GLA (gamma-linolenic acid).
Analyses by ConsumerLab.com found that only 11 of 17 products selected for testing and quality rating met criteria for freshness and labeling. Two plant oil supplements tested were found to be spoiled. Several contained too little or much more of their listed ingredients. Some omega-3 and omega-6 supplements did not properly label the type of oil from which they were made, a FDA requirement.
