Reishi mushrooms (Ganoderma lucidum) have long been revered in traditional medicine as the “mushroom of immortality,” offering numerous life-enhancing health benefits. According to research, they may help bolster immunity, relieve fatigue and regulate sleep-wake cycles while potentially decreasing cancer risks. Reishi is also believed to act as an excellent natural antioxidant and antidepressant.

Adaptogens like Reishi and Cordyceps help the body deal with stress by lowering cortisol levels and supporting a healthy sleep-wake cycle. Furthermore, adaptogens provide a good source of melatonin which supports healthy circadian rhythms for restful night’s rest; adding these mushroom extracts in powder or capsule form to coffee may support better quality restful sleep and increase energy.

Reishi mushroom extracts contain polysaccharides that activate and stimulate immune cells, such as Natural Killer (NK) cells and white blood cells that target infectious pathogens, according to Czerwony. They’re also naturally antiviral, antifungal and antibacterial.

Reishi can improve immune system function while also helping lower the risk of heart disease and increase male libido, according to Kunik. Reishi may even help increase longevity according to studies involving mice.

Reishi supplements are generally safe for most individuals, though some interactions may arise – for instance, blood thinners or anticoagulants could increase bleeding risk when taken alongside Reishi supplements, potentially impacting health conditions such as pregnancy. Consult your healthcare provider prior to taking Reishi if pregnant, planning surgery or have existing medical issues.
