Sleep support; Relaxation; Circadian rhythm support
Adults with busy schedules seeking support for bedtime routine or those with irregular sleep hours such as shift changes.
Adults take 1 tablet 30 minutes before bedtime; as melatonin may cause drowsiness, use only in the evening and avoid alcohol; taking with a small snack may improve comfort if sensitive.
No milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soya, sesame.
Melatonin is a hormone that helps regulate the body’s sleep–wake cycle by signalling darkness to the brain’s circadian clock.
Caution: May cause drowsiness; take only before bedtime and avoid driving or alcohol.
Vitamin B6 acts as a cofactor in neurotransmitter synthesis, which may support normal nervous system function.
Caution: High intakes over time may cause tingling or numbness; keep to suggested use unless advised otherwise.
Calcium contributes to normal neuronal signalling and muscle function as an essential mineral.
Caution: Take with food if sensitive; calcium can interact with some medications by affecting absorption.
Melatonin sets the timing cue for sleep, while vitamin B6 supports neurotransmitter pathways involved in relaxation, and calcium contributes to normal nerve signalling, together aligning sleep cues with nervous system support.
Label Warning: Not intended for insomnia or other sleep disorders. Consult a physician before use if under 18, taking medication, have any medical condition, are pregnant or breastfeeding, or have an autoimmune condition or depressive disorder. May cause drowsiness; avoid driving, operating heavy machinery, or consuming alcohol after taking. Discontinue if adverse reactions occur. For occasional short-term use only. Not a substitute for healthy sleep practices.
Who should be cautious: People using sedatives, sleep aids, or other medications; those with mood concerns, autoimmune conditions, or other ongoing health issues; individuals who are pregnant, breastfeeding, or under 18.
