Third Party Tested & Certified
You train like the best but you’re not seeing the results.
You set your alarm for stupid o'clock because running is non-negotiable. You've got a training plan. You've got the shoes. You've got the will.
But here's what's killing your progress.
You're not recovering. You're just surviving between sessions.
The 5am warrior issue
Your alarm goes off but your legs feel like concrete. Yesterday's intervals are still there, making today's easy run feel like a marathon.
The evening runner's curse
8pm run = 1am sleep. Your body's still buzzing with endorphins when it should be winding down to prepare for your day ahead.
The inevitable PB plateau
Your training is consistent and your times aren't dropping. Poor recovery is the invisible handbrake on your progress.
What elite athletes know that you don't.
Elite athletes treat recovery as seriously as training. They don't just try and sleep longer - they optimise sleep quality through specific nutrition timing, recovery protocols, and targeted supplementation.
NIGHT POWDER brings these elite recovery principles to your bedside table.
You don't need to be an Olympian to recover like one.
A purpose-driven and science backed formula created by the best minds in sports science with a focus on including only the necessary ingredients.
Affron™ is the most clinically-backed saffron extract, used at the 28mg dose commonly found in sports recovery research. Supports the transition from training mode to rest mode, helping with relaxation and emotional balance after demanding sessions.
The amino acid of choice found in high concentrations in muscle tissue. Increasingly popular in athletic circles, particularly among endurance athletes who take it 30-60 minutes before bed.
Clinically studied ingredient backed by human trials in areas like muscle recovery, inflammation, and uric acid levels. This concentrated source of naturally occurring polyphenols and anthocyanins is widely used by professional endurance athletes as part of their recovery routine.
Reduces tiredness and fatigue and supports normal muscle function and electrolyte balance. Contributes to normal nervous system function, and the citrate form is absorbed more quickly to help you wind down faster.
Cellular support minerals that contribute to normal energy metabolism and the protection of cells from oxidative stress. Support normal connective tissue formation, important when logging high weekly mileage.
Don’t just track your metrics. Optimise.
In an independent trial 88% of users saw an increase in their sleep or recovery scores.
