Reishi leads on an unusually strong trial: in a six-month double-blind crossover, 42 adults with mildly raised liver enzymes took an enriched Reishi preparation, and their liver enzymes fell while antioxidant capacity rose. Chaga is second, the antioxidant mushroom, and Turkey Tail third, with the highest beta-glucan content we sell. All three are 10:1 hot water extracts. They are taken to support normal liver function and are not a detox.
Start here. This is the best-matched trial we can point at anywhere on the site: people with mildly raised liver enzymes, six months, and liver markers among the outcomes.
Second, and ranked below its reputation. Chaga is the mushroom most associated with liver support online and the one with the least human evidence for it.
Third, and the indirect entry. The gut and the liver are connected by the portal vein, so a prebiotic argument is a real one, just a longer one.
| # | Mushroom | Key compound | Best for | From |

| 1 | Reishi | Triterpenes, beta-glucans | Antioxidant and evening support | $29.99 |
| 2 | Chaga | Melanin, betulinic acid | Antioxidant support | $32.99 |
| 3 | Turkey Tail | PSP, beta-glucans | Prebiotic and immune support | $29.99 |

What customers report. Individual experience varies; none of this is a clinical claim.
The most interesting liver result in the literature. Forty-two adults aged 40 to 54 with mildly raised liver enzymes and fatty liver took 225 mg daily of a triterpenoid and polysaccharide-enriched Ganoderma lucidum or placebo for six months each, in a double-blind crossover; 39 completed. GPT fell from 22.58 to 13.08 U/L and GOT from 20.65 to 15.50, antioxidant capacity and glutathione rose, and markers of oxidative damage fell. A striking effect from a small dose, in the people most likely to notice one, and it deserves a larger trial to confirm it.
Pharmaceutical Biology · 2017The widest survey of the Reishi literature: 17 clinical trials covering 971 participants, at doses from 200 to 11,200 mg a day. Pooled analysis found significant improvements in BMI, serum creatinine, glutathione peroxidase and resting heart rate. Many other markers did not move, and the reviewers rate the certainty of the underlying trials as low and call for better-designed studies, which is the usual state of a field this active and this young.
Food Science & Nutrition · 2025A review pulling together the modern research on Chaga: antioxidant, anti-inflammatory and immunomodulatory activity, traced to the melanin, polysaccharides and triterpenes the conk accumulates from the birch it grows on. A consistent laboratory picture, and human trials are the natural next step.
Mycology · 2024Twenty-four healthy volunteers were randomised to Turkey Tail polysaccharopeptide, to amoxicillin, or to no treatment, with stool sampled seven times over eight weeks. The Turkey Tail group showed clear and consistent shifts in the gut microbiome, consistent with acting as a prebiotic. A randomised trial in healthy people, which is rare and valuable in this field.
