Evaluation of immune modulation by β-glucan from Ganoderma lucidum: a randomized controlled trial

Foods (peer-reviewed RCT) · Foods, 2023

Species: Humans
Design: Randomized controlled trial
Sample: Healthy adults, placebo-controlled

What it found

Reishi β-glucan produced statistically significant shifts in CD3⁺, CD4⁺, and CD8⁺ lymphocyte subsets and in natural-killer cells relative to placebo.

Why it matters

Human, randomized, and placebo-controlled — but a single trial with intermediate biomarker endpoints. Promising, and still emerging. That distinction is the whole point of the badges.

How much weight this carries

Emerging evidence

Human trials exist but are mixed or early-stage; the mechanism is well characterized.
