Examining the effects of PeptiSleep, a plant-based sleep aid, in healthy males and females with mild to moderate sleep impairment
The primary aim of this is a first in human study is to evaluate safety and establish the effective dose in males and females who experience mild to moderate sleep impairment, but who are otherwise healthy. PeptiSleep will be supplemented one hour before bed as a single oral dose of either 250mg, 500mg or 1000mg/day. A placebo group will also be included who will receive 500mg of microcrystalline cellulose. This trial incorporates a sleep tracking element to measure sleep quality and quantity via a ring which will be worn by participants for the duration of the study. The trial will be conducted over 10 weeks, which includes a 2 week run-in period to gather baseline sleep data, followed by 8 weeks of PeptiSleep supplementation and sleep tracking. The primary endpoint will measure safety and tolerability via adverse event reporting and incidence rate ratio between placebo and PeptiSleep from baseline to the end of the study period. Secondary endpoints investigated during the trial will include changes sleep quantity and quality, insomnia severity, daytime sleepiness, stress and anxiety, alertness, and biochemistry markers (melatonin, serotonin, CRP, TNFα, IL-6, E/LFT). Exploratory endpoints will include various sleep metrics measured via the wearable tracker including heart rate variability, sleep efficiency, respiratory rate, blood oxygen sensing and daily readiness score.

Safety and Tolerability of a dose range of PeptiSleep via adverse event reporting
Change from baseline to the end of the study period in safety via adverse event reporting and incident rate ratio between placebo and a dose range of PeptiSleep
Time frame: Day 0 to 56
Safety via electrolytes and liver function tests
Change from baseline to the end of the study period in safety including electrolytes and liver function markers via blood test
Time frame: Day 0 to 56
Sleep Quality via Leeds Sleep Evaluation Questionnaire
Change from baseline to the end of the study period in Sleep Quality via Leeds Sleep Evaluation Questionnaire (LSEQ). The LSEQ comprises ten self-rating 100-mm-line analogue questions concerned with aspects of sleep and early morning behaviour. A visual analogue scale is used with two extreme states defined at the ends of the line (e. g. Tired = score of 0, Alert = score of 10). The subject responds by placing a vertical mark on the line to indicate his present self- evaluation. The four subscales are as follows: * The ease of getting to sleep (GTS), questions 1-3 * The perceived quality of sleep (QOS), questions 4-5 * The easy of awakening from sleep (AFS), questions 6-7 * The integrity of behaviour following wakefulness (BFW), questions, 8-10
Time frame: Day 0 to 56
Insomnia severity via the Insomnia Severity Index Questionnaire
Change from baseline to the end of the study period in Insomnia Severity via Insomnia Severity Index (ISI). The questionnaire has seven questions. The seven answers are added up to get a total score. Total score categories: * 0-7 = No clinically significant insomnia * 8-14 = Subthreshold insomnia * 15-21 = Clinical insomnia (moderate severity) * 22-28 = Clinical insomnia (severe)

Change from baseline to the end of the study period in Sleep Onset Time via Consensus Sleep Diary (CSD)
Time frame: Day 0 to 56
Sleep pattern via self-reported recording in a Sleep Diary
Change from baseline to the end of the study period in self reported Sleeping Pattern and number of Disturbance as recorded using a Consensus Sleep Diary (CSD)
Time frame: Day 0 to 56
Daytime Sleepiness via the Epworth Sleepiness Scale
Change from baseline to the end of the study period in Day Time Sleepiness and Nap Count via the Epworth Sleepiness Scale (ESS). The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24. The higher the ESS score, the higher the propensity for daytime sleepiness * Scores 0-5 Lower Normal Daytime Sleepiness * Scores 6-10 Higher Normal Daytime Sleepiness * Scores 11-12 Mild Excessive Daytime Sleepiness * Scores 13-15 Moderate Excessive Daytime Sleepiness * Scores 16-24 Severe Excessive Daytime Sleepiness.
Time frame: Day 0 to 56
Stress via the Perceived Stress Scale
Change from baseline to the end of the study period in Stress via a self reported questionnaire - Perceived Stress Scale (PSS). The questions in this scale ask about feelings and thoughts during the last month. The questionnaire asks the participant to indicate how often they felt or thought a certain way with 0 meaning never and 4 meaning very often. PSS scores are calculated by: * First, reverse your scores for questions 4, 5, 7, and 8. On these 4 questions, change the scores like this: 0 = 4, 1 = 3, 2 = 2, 3 = 1, 4 = 0. * Add up your scores for each item to get a total. * Individual scores on the PSS can range from 0 to 40 with higher scores indicating higher perceived stress. * Scores ranging from 0-13 would be considered low stress. * Scores ranging from 14-26 would be considered moderate stress. * Scores ranging from 27-40 would be considered high perceived stress
Time frame: Day 0 to 56
Stress via self reported Profile of Mood States Questionnaire
Change from baseline to the end of the study period in Stress via a self reported questionnaire called Profile of Mood States (POMS). The questionnaire contains 65 words that describe feelings which are rated from 0-4. Scores are calculated: * Tension = Tense, Shaky, On Edge, Panicky, Relaxed, Uneasy, Restless, Nervous and Anxious * Depression = Unhappy, Sorry for Things Done, Sad, Blue, Hopeless, Unworthy, Discouraged, Lonely, Miserable, Gloomy, Desperate, Helpless, Worthless, Terrified and Guilty * Anger = Anger, Peeved, Grouchy, Spiteful, Annoyed, Resentful, Bitter, Ready to Fight, Rebellious, Deceived, Furious and Bad Tempered * Fatigue = Worn Out, Listless, Fatigued, Exhausted, Sluggish, Weary and Bushed * Confusion= Confused, Unable to Concentrate, Muddled, Bewildered, Efficient, Forgetful, and Uncertain About Things * Vigour =Lively, Active, Energetic, Cheerful, Alert, Full of Pep, Carefree and Vigorous
