This supplement is a blend of organic, cold-pressed flax, olive and sunflower seed oils, which supplies the desired levels and ratios of Omega 3, 6 and 9 Essential Fatty Acids (EFA’s). These compounds are called essential because they are not synthesized by the body and, therefore, must be obtained from dietary sources. EFA’s serve as components of nerve cells, cellular membranes, and the very important regulatory substances known as prostaglandins.
