Leucotriene modulating effects of omega-3 EFAs compare favourably to NSAIDs.13 Beneficial effects of GLM have been observed between 2 and 4 weeks of treatment in a number of studies;18–20 this length of delayed effect is comparable to the time span for the clinical effects of EFAs in arthritis to be apparent.21.
