Chronic Fatigue Syndrome (CFS – ME)

CFS patients show immune dysfunction, including low NK cell activity, and the condition has been linked to high viral counts, especially Epstein-Barr virus (EBV). Recent research confirms the elevated levels of Th2 cytokines in patients with CFS and prevailing Th2 inflammatory milieu, together with highly attenuated Th1 immune response1-3.

The proven ability of mushroom nutrition to promote a shift away from a Th2 dominant immune response and increase anti-viral activity makes it a natural source of support for CFS patients with good clinical results, including increased NK cell activity and improved lifestyle scores. Trametes versicolor mycelial biomass produced a 35% increase in NK cell activity in patients with mild CFS at a dose of 1.5-3g/day (more severe cases are reported to respond to higher dosages)4.

CFS is a condition that responds well to a range of medicinal mushrooms with polysaccharide extracts giving particularly good results (1-3g/day).
