Real people. Real sleep. Subtle calm you feel within a week — without melatonin or grogginess.
Science-backed sleep
No hype. No dependency. Just science that actually works.
We’ve lived the wired-but-tired cycle — the 3 a.m. wake-ups, the heavy mornings, the quiet exhaustion. Nitra was created by people who refused to accept “this is just how life is.”
The NITRA® Formula
The Science
Why we can’t sleep
Screens, stress, and late caffeine raise cortisol while suppressing GABA and glycine. Nitra restores that balance naturally. It’s not sedation — it’s restoration.
Your Nights, Reengineered — Every Night
Clinically balanced ingredients. Designed to restore what modern life takes away. A simple ritual that helps you fall asleep faster, sleep deeper, and wake clear.
Deep Sleep
Glycine + Magnesium Bisglycinate cool the body and relax muscles — supporting long, restorative sleep cycles.
Mood
Saffron lift serotonin naturally, so you wake calm, balanced, and emotionally reset.
Morning Recovery
A full night’s recovery means more focus, better skin, steadier energy — without caffeine or grogginess.
