Reishi
Ganoderma lucidum / lingzhi · Sleep
A bitter mushroom with a long tradition for calm and immunity and thin modern data.
What the evidence says
Small trials on fatigue and immune markers; the sleep claim is traditional rather than measured.
What studies used
Labels commonly list 1-2 g extract per day.. Evening, per most labels..
Reported from published studies and product labelling — a record of what was used in research, not a recommendation. What is right for you is a conversation with a clinician.
Watch out for
