Participants must be aged 18-35yrs, recreationally active i.e. completing at least 150 to 300 min moderate-intensity activity or 75–150 min of vigorous-intensity activity a week, plus muscle-strengthening activities 2 or more days a week.
Participants must not be facing any existing sleeping disorders such as insomnia or consuming any nutraceutical or herbal sleeping aids such as melatonin gummies, chamomile or other herbs which could influence exogenous melatonin production.
Participants will be screened using the Pittsburgh Scale Quality Index (PSQI) questionnaire and a score of >5 will be excluded from the trial.
Excessive beer or wine consumption (>17 standard drinks per week), dairy allergy, high caffeine use (e.g., >5 mg·kg-1·d-1), antidepressant or sleep medication use, current or recently finished night shift work, recent transmeridian travel, fluctuating bedtimes, and pregnancy are also exclusions from this trial due to confounding influences that may have on the circadian rhythm, exogenous melatonin production or the plasma TRP:LNAA ratio.
