Research Summary
Multiple human clinical trials demonstrate Turkey Tail's efficacy in supporting immune function and enhancing gut microbiome diversity, particularly through its prebiotic polysaccharide content. Research indicates PSK extracts may support recovery in certain health conditions when used adjunctively. However, more robust Western clinical evidence is needed to establish optimal dosing and full scope of benefits in diverse populations.
