What is reishi and how does it support immune function?

Reishi (Ganoderma lucidum) is a medicinal mushroom used for centuries in East Asian medicine. Its beta-glucans and triterpenes have been studied for their potential to enhance natural killer cell activity, modulate cytokine production, and support overall immune surveillance.

What dosage of reishi has been used in clinical studies?

Clinical trials have used reishi extract at doses of 1.5–5.4 g per day of extract, or up to 9 g per day of dried mushroom powder. Standardized extracts containing 10–30% polysaccharides are most commonly used in research.

About

Reishi (Ganoderma lucidum) contains beta-glucans that bind to pattern recognition receptors (Dectin-1, CR3) on macrophages and dendritic cells, activating innate immune cascades. Its triterpenes modulate NF-kB signaling and cytokine production, and it enhances NK cell cytotoxicity. Over 400 bioactive compounds have been identified.

How It Works

Beta-glucans bind to pattern recognition receptors (Dectin-1, CR3) on macrophages and dendritic cells, activating innate immune cascades; triterpenes modulate NF-kB signaling and cytokine production; enhances NK cell cytotoxicity.
