Sleep is a biological process regulated by the nervous system, neurotransmitters, and physical relaxation. When stress, mental overactivity, or muscle tension are elevated, the body can struggle to fall asleep or stay asleep.
This formula is designed to support the body’s natural sleep processes rather than override them. Each ingredient is included in a bioavailable form and an evidence-aligned dose, chosen to gently support mental calm, sleep onset, and sleep quality without sedation or disruption of natural sleep rhythms.
Supporting mental calm
Reducing stress, nervous tension, and racing thoughts
Many sleep difficulties begin with an overstimulated nervous system. The following ingredients support a calmer mental state in the evening, helping the brain shift away from alertness.
L-theanine (200 mg, 98% from green tea)
L-theanine is a naturally occurring amino acid found in tea leaves. Research shows it promotes a calm but alert mental state by increasing alpha brain wave activity and influencing neurotransmitters involved in relaxation.
Human studies suggest L-theanine may reduce stress and support sleep quality without causing sedation or cognitive impairment. The 200 mg dose used here is the most commonly studied and well tolerated.
Safety
L-theanine has been widely studied and is considered safe for daily use at doses well above 200 mg. It is non-sedating and non-habit forming.

Saffron extract (28 mg, safrinside®, 3.5% lepticrosalides)
Saffron has been traditionally used to support emotional wellbeing and has been studied for its effects on mood and stress regulation. Research suggests saffron may influence serotonin-related pathways, which are involved in emotional balance and sleep regulation.
The dose and standardisation used here match those commonly used in human studies.
Safety
Clinical trials using 28 to 30 mg per day report good tolerability with no serious adverse effects. Saffron is not associated with sedation or dependence at supplemental doses.

Purple passionflower extract (10:1, 50 mg)
Passionflower has a long history of traditional use for nervous tension and restlessness. It is believed to support calming GABA-related pathways in the brain, which help reduce mental overstimulation.
Research suggests passionflower may support subjective sleep quality and reduce anxiety, particularly in individuals prone to overthinking.
Safety
Passionflower is generally well tolerated when used at typical supplemental doses. It is not considered habit forming and does not act as a sedative at low to moderate doses.

Supporting sleep onset
Helping the body and mind transition naturally into sleep
Falling asleep requires coordinated changes in nervous system activity, neurotransmitter signalling, and body temperature. These ingredients support that transition.
Glycine (2.5 g)
Glycine is an amino acid involved in inhibitory neurotransmission and thermoregulation. Research shows glycine may help lower core body temperature and promote relaxation, both important for sleep initiation.
Clinical studies suggest doses around 2 to 3 grams may improve subjective sleep quality and ease the transition into sleep.
Safety
Glycine is a naturally occurring amino acid and is considered safe at doses used in sleep research. It is not sedating and does not interfere with normal sleep architecture.

German chamomile flower extract (10:1, 50 mg, standardised to 1 mg apigenin)
Chamomile has been traditionally used to promote calm and prepare the body for rest. Apigenin, its key bioactive compound, binds to receptors involved in relaxation.
Clinical research suggests chamomile may support mild improvements in sleep quality and anxiety without acting as a sedative.
Safety
Chamomile is widely regarded as safe when used in food and supplements. Standardised extracts at this dose are gentle and unlikely to cause next-day drowsiness.

Hops flower extract (10:1, 50 mg)
Hops have been used traditionally to support relaxation and sleep. Research suggests hops may interact with calming neurotransmitter systems, including GABA pathways.
In this formula, hops are included at a conservative dose to complement other calming ingredients rather than act as a strong sedative.
Safety
Hops extracts are generally well tolerated at low to moderate doses. The amount used here is considered appropriate for regular use.

Supporting restful, uninterrupted sleep
Physical relaxation and sleep quality
Magnesium (250 mg from magnesium bisglycinate)
Magnesium plays a key role in nervous system regulation, muscle relaxation, and stress response. Magnesium bisglycinate is a highly bioavailable and well tolerated form.
Research suggests magnesium supplementation may support improved sleep quality and reduced nighttime restlessness, particularly in individuals with suboptimal magnesium intake.
Safety
Magnesium bisglycinate is considered gentle on digestion and safe at supplemental doses of 200 to 400 mg per day in healthy adults.

Vitamin B6 (2 mg as pyridoxal-5-phosphate)
Vitamin B6 is required for the synthesis of neurotransmitters such as serotonin and GABA, which are involved in relaxation and sleep regulation. The P-5-P form is biologically active and does not require conversion by the body.
Vitamin B6 also supports effective magnesium utilisation.
Safety
The dose included is modest and well within established safety limits. Adverse effects are associated only with long-term use of very high doses.

Thoughtful formulation and overall safety
This formula is intentionally non-sedating and non-habit forming. It does not rely on melatonin, strong sedative herbs, or high-dose single ingredients. Instead, it uses moderate, evidence-aligned doses that work together to support the body’s natural sleep rhythm.
The goal is not to force sleep, but to help create the internal conditions that allow sleep to occur naturally and consistently.
