Bristol Fungarium's 1:4 Reishi Mushroom Tincture: UK-grown organic Reishi tincture, cloned in lab. Triple Extracted, 1: 4 Ratio via two hot water extractions and a final organic ethanol extraction to gain access to all the bioactive compounds responsible for Reishi's beneficial properties. (1g of mushrooms to every 4ml of water).
Study summary
Examining the effects of 1ml of Reishi mushroom extract (1:4 extraction ratio, two hot water extractions and an alcohol extraction), taken daily, 30 mins before bed on perceived sleep quality and stress levels. Sleep quality includes: duration, sleep onset latency, nighttime wakings, and perceived restfulness. And consequently, the potential for increased daytime energy levels and a reduction in perceived stress levels.

Primary outcome measure(s)
Perceived Stress Scale (Past Week Version) — Change from baseline (Day 1-5) in perceived stress levels at 4-5 weeks after the start of the intervention The Perceived Stress Scale (Past Week Version) is a modified version of the classic stress assessment tool that evaluates stress levels based on recent experiences within the last week. This scale helps in understanding how various situations have recently affected an individual's feelings and perceived stress levels. By focusing on a shorter time frame, it provides a more immediate assessment of stress, which can be particularly useful for quickly evaluating the effectiveness of stress management strategies or interventions. The tool retains its original structure, ensuring its reliability while making it more relevant for current stress evaluation.
Score Range
Minimum score: 0
Maximum score: 40
Score Interpretation
Higher scores = worse outcome
Higher scores indicate greater perceived stress
Neuro-QOL Item Bank v1.0 -Fatigue - Short Form — Change from baseline (Day 1-5) in fatigue levels at 6-7 weeks after the start of the intervention This survey aims to assess the level of fatigue experienced by the participant in the past 7 days. Each question should be answered by selecting one of the five options ranging from 'Never' to 'Always'.

Score Range
Raw score range:
Most commonly used short forms: 8-40
T-score range (standardized):
Typically \~30 to \~80, mean = 50, SD = 10
Score Interpretation
Higher scores = worse outcome
Higher scores reflect greater fatigue severity and impact
PROMIS Sleep Disturbance Scale — Change from baseline (Day 1-5) in sleep disturbance levels at 6-7 weeks after the start of the intervention The PROMIS Sleep Disturbance Scale is a validated and widely used assessment tool developed as part of the Patient-Reported Outcomes Measurement Information System (PROMIS) initiative. It is designed to measure the severity of sleep disturbances and disruptions experienced by individuals. This scale includes a range of questions that assess the frequency and impact of various sleep-related issues, such as difficulty falling asleep, nighttime awakenings, and restless sleep. Healthcare professionals and researchers rely on this scale to better understand and quantify sleep problems in patients, enabling them to tailor interventions and treatment strategies to address sleep-related concerns effectively.
