A method for making a fatty acid mineral salt is disclosed where liquid oils containing fatty acids are hydrolyzed using a base solution. A buffering agent is added to the hydrolyzed solution to maintain pH between 8.0 and 11.0 followed by a water soluble metal salt solution which causes a metathesis reaction with the hydrolyzed solution, forming a precipitates of fatty acid metal salts which are glycerin-free. The precipitates are filtered, washed and subsequently dried. The produced fatty acid metal salt is easier for the human body to digest than omega-3 fatty acid in oil form and also is less prone to oxidation and emitting of unpleasant odor.
