These are published studies on the compounds in this mushroom family: research on the ingredient, not claims about this product.
Saitsu et al., Biomedical Research, 2019: Adults over 50 took 3.2 g a day of powdered Lion's Mane fruiting body for twelve weeks in a double-blind, placebo-controlled trial. Cognitive assessment scores rose significantly against placebo. The closest match in the literature to a fruiting body product like this one. Read the study →
La Monica et al., Nutrients, 2023: One of the few trials to name its preparation precisely: 1 g of 100% organic Nordic Lion's Mane fruiting bodies. Forty healthy adults took it or placebo in a double-blind crossover. Performance improved on a serial subtraction task, on working-memory reaction time and on reaction time to a go stimulus, and participants rated themselves happier. Read the study →
Mori et al., Phytotherapy Research, 2009: A double-blind, placebo-controlled trial in older adults found cognitive scores improved across sixteen weeks of daily Lion's Mane, then drifted back after supplementation stopped, which is the clearest sign that the mushroom was doing the work.

Docherty et al., Nutrients, 2023: A double-blind pilot in healthy young adults reported faster performance on a processing-speed task within an hour of a single dose, and lower self-reported stress after 28 days of daily use. Read the study →
Nagano et al., Biomedical Research, 2010: A four-week placebo-controlled study in adult women, using 2 g a day of powdered fruiting body baked into cookies, reported improvements in mood and everyday complaint scores. Read the study →
