The Science of Sleep
Built for the way the body actually rests.
NITRA is designed around established sleep physiology — not trends, stimulants, or sedatives.
It supports the biological conditions the body needs to fall asleep naturally, remain asleep, and wake feeling clear.
This is not about forcing sleep.
It’s about restoring the signals that allow it.
Why Sleep Breaks
Modern sleep problems are rarely about discipline.
They’re about a nervous system that never fully stands down.
Artificial light delays night-time signals.
Stress elevates evening cortisol.
Mental stimulation sustains alertness long past the day’s end.
Mineral depletion weakens relaxation pathways.
The result is familiar: exhaustion without rest.
The feeling of being tired, but wired.
How Sleep Begins
Sleep is not a switch.
It is a coordinated transition.
For the body to move into sleep, several signals must align:
-
Core temperature gradually lowers
-
The nervous system shifts toward parasympathetic dominance
-
GABA signalling becomes rhythmic and stable
-
Evening cortisol softens
-
Mental activity quiets without suppression
When these conditions are present, sleep follows naturally.
NITRA is formulated to support this transition — gently and consistently.
Why These Ingredients
Every ingredient in NITRA has a defined physiological purpose.
None are included for novelty. None stimulate. None sedate.
All ingredients are formulated within established, safe, and effective ranges, selected specifically for nightly use.
Glycine
Supports the natural reduction in core body temperature — one of the body’s strongest cues for sleep onset. Associated with deeper sleep architecture and clearer mornings.
Magnesium Bisglycinate
A highly bioavailable form of magnesium chosen for nervous system support and muscle relaxation, without digestive disruption.
L-Theanine
Supports alpha-wave calm — the mental state between focus and sleep. Helps quiet cognitive activity without dulling awareness.
Lemon Balm & Chamomile
Traditionally used to ease stress response, support digestion, and promote gentle evening calm — an often overlooked factor in sleep quality.
Magnolia Bark
Supports GABA-A receptor activity, contributing to physical relaxation and reduced nighttime tension.
Taurine
Helps regulate nervous system signalling and supports steady cardiovascular rhythm during rest.
Fermented GABA
Reinforces the body’s primary inhibitory pathway, supporting smooth transitions into sleep without sedation.
Saffron Extract
Associated with emotional balance and next-day clarity, helping sleep feel restorative rather than heavy.
Why a Drink
Sleep is not purely chemical.
It is behavioural, sensory, and rhythmic.
Capsules limit dose capacity, absorption dynamics, and ritual.
A warm drink does the opposite.
Liquids absorb efficiently.
Warmth signals safety.
Ritual slows behaviour and cues rest.
NITRA is designed as a nightly practice, not a pill.
What NITRA Is Not
NITRA is:
-
Melatonin-free
-
Non-sedating
-
Non-habit forming
-
Designed for consistent nightly use
NITRA is not:
-
A sleeping pill
-
A knockout solution
-
A stimulant
-
A dependency
It does not override the body.
It supports what the body already knows how to do.
What to Expect
Sleep improves through consistency, not force.
Many people experience:
-
Easier sleep onset within the first few nights
-
Fewer nighttime awakenings as the system settles
-
Deeper, steadier sleep developing over 7–14 nights
Consistency matters more than intensity.
Safety
NITRA is a food supplement formulated within recognised safety parameters.
Suitable for most adults when used as directed.
If pregnant, breastfeeding, or taking medication, consult a healthcare professional.
The Principle
Sleep does not need to be forced.
It needs to be supported.
NITRA exists to help the body remember how to rest —
calmly, consistently, naturally.
