As of 1986, a team of researchers comprised of pharmacists and doctors imagined using omega-3 (marine-derived polyunsaturated fatty acids, EPA and DHA) by combining them with vitamins and trace elements to restructure cellular activity better and have an impact on the body’s different metabolism. Since then, several studies have pointed out the benefits we can expect of these omega-3 fatty acids.
