Study Evaluating the Quality and Effects of Lion's Mane Product on Cognitive Health
What this study is about
The rationale for this study is to observe differences in cognitive health outcomes such as short term memory and simple reaction time between a consumer-grade and commercially available Lion's mane mushroom product and a placebo control group. Additionally, the study aims to evaluate the impact of the product on cognitive function, mood, focus, motivation, sleep quality, and stress.
View original scientific description
The rationale for this study is to observe differences in cognitive health outcomes such as short term memory and simple reaction time between a consumer-grade and commercially available Lion's mane mushroom product and a placebo control group. Additionally, the study aims to evaluate the impact of the product on cognitive function, mood, focus, motivation, sleep quality, and stress. A consumer-driven, decentralized observational clinical research study is therefore well-suited for evaluating the impact of this product in this population. The study will evaluate cognitive health outcomes in a broad age-range of adults who have chosen to try this product. The study will incorporate memory and cognitive function tests, participant reported outcome questionnaires and surveys. There is no "doctor-patient" relationship as part of this research since the participant as a consumer is making the informed choice to take the product and participate in the observational process with self-reported measures that can be done at home. Findings from this study will contribute knowledge toward the functional mushrooms and cognitive health and the design of future studies.
Interventions
DIETARY_SUPPLEMENT
Lion's Mane Study Product
The Lion's Mane Study product contains vegetable cellulose (capsules), Certified organic Lion's Mane (Hericium erinaceus) fruiting body and mycelial biomass cultured on certified whole oats (Avena sativa). Screening assessments, scales and surveys during baseline and during the use of the study product/placebo and end of study experience survey data will be collected.
Primary outcome measures
Impact on Attention, Short Term & Working Memory
Time frame: Participants will complete up to a 14-week study consisting of screening period, randomization and shipping period, a baseline period, and an 8-week product/placebo use period.
The primary outcome measure is to evaluate the impact of the Lion's Mane study product on a composite measure of Attention, Short Term \& Working Memory. This will be measured using the change from baseline in BrainHQ Cognitive Test Suite composite score at Week 8 between placebo and study product group.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
