What is Reishi Mushroom?

Reishi (Ganoderma lucidum), known in China as Lingzhi or 'the mushroom of immortality,' has been used in East Asian medicine for over 2,000 years as a calming, immune-balancing adaptogen. Its bioactive polysaccharides (beta-glucans) and triterpenes appear to modulate immune signaling, supporting the body's response under both immune-suppressed and immune-overactive conditions. Reishi has a gentle calming effect that makes it well-suited for evening use, where it may support sleep depth and relaxation without sedation. Standard doses are 1-3 g of dual-extracted whole-mushroom powder per day. It pairs well with magnesium and ashwagandha for an evening wind-down routine.
