Rapid immune effects of Agaricus, Reishi, and Turkey Tail mushrooms

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional trial compares acute immune responses after ingestion of three medicinal mushrooms (Agaricus, Reishi, and Turkey Tail) versus a placebo in healthy adults aged 18–75. Participants follow a controlled routine and undergo multiple blood draws to measure pro- and anti-inflammatory cytokines, markers of immune cell activation, and immune cell trafficking related to circadian cycles. The protocol excludes people with major gastrointestinal surgery, those on daily anti-inflammatory medications, individuals undergoing intensive athletic training, and those experiencing major life stress. All visits take place at NIS Labs in Klamath Falls, Oregon.
