Reishi

What it is
Reishi is a medicinal mushroom that has been used for centuries in East Asian traditional medicine, often associated with longevity, vitality, and resilience. It contains a range of bioactive compounds, including beta-glucans, triterpenes (such as ganoderic acids), and polysaccharides, which are believed to contribute to its health effects [1].

Reishi is commonly classified as an adaptogen-like functional mushroom, meaning it may help the body maintain balance under physical and psychological stress.

How it works in the body
Reishi’s beta-glucans are known to interact with immune cells such as macrophages and natural killer (NK) cells, helping to modulate immune system activity rather than simply stimulate it [2]. This supports its use in maintaining immune balance and resilience.

Its triterpenes and other compounds also exhibit antioxidant and anti-inflammatory properties, helping to reduce oxidative stress and support cellular protection. These effects may contribute to its role in overall health and long-term resilience [3].

Reishi has also been studied for its potential effects on the stress response, with some research suggesting it may influence pathways related to fatigue, sleep, and overall well-being. This has led to its inclusion in formulations targeting stress management, recovery, and general vitality.

Emerging research also points to possible benefits for cardiometabolic health, including effects on blood pressure and lipid profiles, though findings are still developing.
