Seed oils are popular supplements that provide omega-3 and omega-6 fatty acids.  Flaxseed oil is particularly rich in the omega-3 fatty acid ALA (alpha-linolenic acid) and hemp seed oil is also a good source. Black currant, borage, and evening primrose oils are good sources of the omega-6 fatty acid GLA (gamma-linolenic acid).
 
But which are the best black currant oil, borage oil, evening primrose oil, flaxseed oil, and hemp oil supplements? 
 
Analyses by ConsumerLab.com found that only 14 of 17 products selected for testing met criteria for freshness and labeling accuracy. The most common problem was with freshness, as indicated by high levels of oxidation.
