Simple explanations of common terms used when researching serotonin, sleep, mood and 5-HTP supplements.
5-HTP (5-Hydroxytryptophan)
A naturally occurring compound the body uses to produce serotonin. Most supplements are derived from the seeds of the Griffonia simplicifolia plant.
Amino Acids
Building blocks of protein that play important roles in neurotransmitter and hormone production.
Appetite Regulation
The biological processes that influence hunger and satiety. Serotonin is commonly discussed in relation to appetite signals.
Brain Chemistry
A general term describing the neurotransmitters and chemical messengers that influence mood, sleep and behaviour.
Circadian Rhythm
The body’s internal 24-hour clock that regulates sleep and wake cycles.
Cortisol
A hormone released during stress that can influence sleep quality and nervous system balance.
Dopamine
A neurotransmitter involved in motivation, reward and focus.
Emotional Regulation

Endocrine System
The network of glands that produce and regulate hormones throughout the body.
Evening Wind-Down
A term used to describe routines that help signal to the body that sleep is approaching.

A West African plant whose seeds naturally contain high concentrations of 5-HTP.
Hormonal Balance
A general term used to describe stable and normal hormone regulation.
Insomnia
Difficulty falling asleep or staying asleep. Sleep support is one of the most common reasons people research 5-HTP.
Light Exposure
Exposure to daylight and artificial light, which strongly influences circadian rhythm and sleep timing.
Melatonin
A hormone produced from serotonin that helps regulate the sleep cycle.
Mood Balance
A general term used to describe emotional stability and wellbeing.
Nervous System
The network of nerves and brain structures that control body functions and responses.
Neurotransmitters
Chemical messengers used by the brain and nervous system to communicate.
Non-Stimulant
A substance that does not stimulate the central nervous system like caffeine.
REM Sleep
A stage of sleep associated with dreaming and cognitive recovery.
Restlessness
A state of physical or mental agitation often discussed in relation to stress and sleep.
Serotonin
A neurotransmitter involved in mood, sleep, appetite and nervous system regulation.
Serotonin Pathway
The biological process that converts tryptophan into serotonin and melatonin.
Serotonin Precursor
A compound the body uses to create serotonin. 5-HTP is a direct precursor.
Serotonin Production
The process by which the body creates serotonin from dietary nutrients.
Sleep Cycle
The repeating pattern of sleep stages throughout the night.
Sleep Hygiene
Daily habits and environmental factors that influence sleep quality.
Stress Response
The body’s physiological reaction to physical or psychological stress.
Supplement Transparency
The practice of openly sharing ingredient sourcing, testing and production information.
Tryptophan
An essential amino acid found in protein foods. The body converts tryptophan into 5-HTP and then serotonin.
Vitality
A general term used to describe overall energy and wellbeing.
