Hemp seed oil has been dubbed "Nature's most perfectly balanced oil", due to the fact that it contains the perfectly balanced 3:1 ratio of Omega 6 (linolei/LA) to Omega 3 (alpha-linolenic/LNA) essential fatty acids, determined to be the optimum requirement for long-term healthy human nutrition. In addition, it also contains smaller amounts of 3 other polyunsaturated fatty acids in gamma-linolenic acid (GLA), oleic acid and stearidonic acid. The EFA combination is unique among edible oil seeds.
