What is Longelite Sleep Complex?
Longelite Sleep Complex is a premium dietary supplement designed based on the latest scientific evidence. It contains a combination of natural compounds, amino acids, herbal extracts, and cofactors whose effectiveness in improving various parameters of sleep quality has been repeatedly demonstrated in controlled human studies – shortening sleep onset time, extending total sleep duration, increasing the proportion of deep and REM sleep, improving both subjective and objective sleep quality, and reducing anxiety and stress before falling asleep.

Key active compounds
Apigenin
A natural flavonoid with proven anxiolytic effects.
Tryptophan
An essential amino acid that is a key precursor of the neurotransmitter serotonin and subsequently the hormone melatonin.
P-5-P (active B6)
The active form of vitamin B6 and an essential cofactor for enzymes involved in the synthesis of GABA, serotonin, dopamine, and melatonin.
Glycine
A simple amino acid with proven effects on sleep quality and overnight recovery.
Myo-inositol
An important secondary messenger in brain neurotransmitter pathways.
L-theanine
An amino acid naturally occurring in green tea leaves.
Herbal extracts
With clinically validated effects on sleep, stress, and circadian rhythm: valerian, lemon balm, passionflower, lavender, sour cherry.
Why Longelite Sleep Complex?
The product combines anxiolytic, relaxing, and neuroregulatory compounds that act through multiple mechanisms:
- modulation of GABA receptors (calming the nervous system),
- support of serotonin and melatonin synthesis (sleep onset and circadian rhythm regulation),
- reduction of stress hormone levels (especially cortisol, which disrupts sleep onset and sleep quality),
- improved thermoregulation (for the proper drop in body temperature for sleep),
- optimization of sleep architecture and sleep quality (increasing the proportion of deep and REM sleep, improving sleep efficiency).

What does science say?
“High-quality sleep is undeniably one of the pillars of longevity and overall health. Chronic sleep deprivation has repeatedly been associated with an increased risk of almost all major lifestyle-related diseases, disrupts immune system function, and very likely accelerates biological aging. Beyond sleep duration, sleep quality and structure (so-called sleep architecture) also play a key role – fragmented sleep, a low proportion of deep (N3) and REM sleep, or a disrupted circadian rhythm have been consistently linked in observational and longitudinal studies to higher mortality, insulin resistance, and cognitive decline in older age.
Conversely, regular, sufficiently long, and high-quality sleep has been associated in multiple studies with a lower risk of heart attack, type 2 diabetes, depression, and Alzheimer’s disease, lower levels of inflammatory markers and better insulin sensitivity, and lower overall and cardiovascular mortality.
Longelite Sleep Complex was designed to support precisely those aspects of sleep that have a key impact on health and aging: it supports the synthesis and activity of GABA and serotonin, two key neurotransmitters regulating sleep, mood, and the stress response, reduces cortisol levels and facilitates calming of the nervous system, contributing to easier sleep onset and deeper sleep, increases the proportion of deep (N3) and REM sleep – phases crucial for nervous system recovery, hormonal balance, and immune function, stabilizes circadian rhythm thanks to natural melatonin and compounds influencing its production, improves sleep efficiency and reduces night awakenings,
and through better sleep quality contributes to brain health, hormonal balance, and psychological resilience.
Adequate, high-quality sleep is one of the few processes that positively affects virtually every organ system in the body and supports slower biological aging.”

How to take Longelite Sleep Complex?
- Recommended daily dose: 10,2 g (equivalent to 2 slightly underfilled scoops according to the mark). Mix in 200 ml of water and drink 30–60 minutes before sleep.
- With or without food: Without food
- Time of day: In the evening, ideally at the same time every day to support circadian synchronization.
- Do not exceed the recommended dose – the product and its dosage are formulated based on clinical studies demonstrating its efficacy and safety.
- Do not combine with alcohol or stimulants (especially caffeine) in the evening.
- For synergistic effects, it can be combined with regular sleep hygiene, for example minimizing blue light in the evening, maintaining a consistent bedtime, and spending time in daylight during the day.
- The product is not a substitute for sleep hygiene – the ideal approach is to combine it with light hygiene (reducing blue light in the evening, morning light exposure, and sufficient light during the day).
- The effect typically starts within 1 hour after use. Full improvement in sleep quality usually occurs within 1–2 weeks of regular use.
- Also suitable for individuals with mild mood disorders, anxiety, or a disrupted circadian rhythm (e.g., shift work, jet lag).
Warnings
Do not exceed the recommended daily dose. This product is not a substitute for a varied and balanced diet. Keep out of reach of children. Not intended for children, pregnant or breastfeeding women. Store in a tightly closed container, in a dry and dark place.
Who is it not recommended for?
Use of this dietary supplement is not recommended for:
- pregnant and breastfeeding women (insufficient safety data)
- people taking strong sedatives or hypnotics – possible additive effect
- people with an allergy to any ingredient,
- children and adolescents (insufficient safety data)
