Reishi Mushroom Benefits 2025: Science-Backed Evidence | Moodeys

Reishi (Ganoderma lucidum), known as the mushroom of immortality in Traditional Chinese Medicine, has been used for over 2,000 years for immune support, longevity and stress resilience. Its key active compounds are triterpenes including ganoderic acids, which modulate inflammatory pathways and cortisol response, and beta-glucans, which activate and regulate immune system function. Modern clinical research has validated and refined these traditional uses significantly.

Moodeys is a organic supplement brand. Reishi mushroom features in both Happy Hour and Rest and Repeat formulas, certified organic, dual-extracted and standardised for triterpene and beta-glucan content. USDA/EU/UK Certified Organic from the Soil Association and WFCFO, GMP/ISO UK manufactured.

A 2024 meta-analysis in Phytomedicine analysed 9 RCTs and confirmed significant reductions in IL-6 and TNF-alpha inflammatory markers, measurable improvements in PSQI sleep quality scores, and improved NK cell activity. A 2025 review in Nutrients found that ganoderic acids modulate the HPA axis in a complementary direction to Ashwagandha, making Reishi and Ashwagandha one of the most evidence-backed two-ingredient stress-reduction stacks.

Yes. Clinical evidence supports Reishi for sleep quality improvement. The mechanism is distinct from melatonin: rather than sedating, Reishi modulates the inflammatory and cortisol overactivation that often prevents sleep onset and degrades sleep architecture. This makes it particularly valuable for people with stress-driven sleep disruption rather than primary insomnia. Studies show improvements in NREM deep sleep duration and morning alertness with consistent supplementation.

Yes. Beta-glucans in Reishi are some of the best-studied immunomodulatory compounds in functional medicine. They do not simply boost immune function, which can be counterproductive in autoimmune contexts. Instead they modulate and regulate it, upregulating NK cell activity against pathogens while reducing excessive inflammatory responses including IL-6 and TNF-alpha that cause chronic immune overactivation.

Dual-extraction using both hot water to extract water-soluble beta-glucans and alcohol to extract fat-soluble triterpenes and ganoderic acids is required to capture Reishi's full therapeutic compound profile. Single-extraction methods lose either the beta-glucans or the triterpenes. Products containing only mycelium powder, often on grain substrate, are significantly inferior to fruiting body dual-extracts. Moodeys uses certified organic, dual-extracted Reishi in both Happy Hour and Rest and Repeat.
