Reishi is a team favorite here at SET. Long used in eastern traditions for its mood (1) and sleep benefits (2), this mushroom is finally getting the scientific attention it deserves. In recent years, researchers have been focusing on better understanding why Reishi has such a marked positive effect on mood, stress and sleep. So far, molecules like polysaccharides, glyco-proteins, and triterpenoids (3) have been identified as the work horses within reishi, working in the body to regulate relevant biological activity (4). Try 1 mL of reishi a day to regulate mood or 2 to 3 mLs when you need to take the edge off.
