Hydrated sleep, trusted by high performers.

7 Reasons People Are Switching To This Nighttime Hydration Stick For Deeper Sleep

LEARN MORE

Most people think poor sleep is about blue light or melatonin. But the real problem might be hiding in your hydration.

Here’s why thousands are adding Core Sleep by Cadence to their nightly ritual, and finally waking up clear, recovered, and human again.

.01

You Lose More Water Overnight Than You Think

Every night, your body loses fluid through breathing, sweat, and natural hormone cycles, even if you don’t feel it.

Waking up dry-mouthed, stiff, or foggy? That’s likely low-grade overnight dehydration.

.02

Most People Start The Night Underhydrated

We’re not talking about sipping water before bed.

We’re talking about real hydration, getting the right minerals in the right ratios, so fluid actually reaches your cells.

Most people don’t. And it’s silently wrecking sleep quality and next-day performance.

.03

Sleep Hydration Was Built To Fix This, Scientifically

This isn’t melatonin or sleepy tea.

It’s a precision formula developed by elite performance experts, for high-output founders, athletes, and everyday grinders who need to wake up sharp.

Each stick contains:

  • 100mg Sodium - The cornerstone mineral for fluid balance and deep sleep

  • 100mg Potassium - Supports nervous system and cellular hydration

  • 50mg Magnesium - Calms the body, aids recovery, promotes relaxation

8 Evidence-Based Sleep Ingredients For Deeper, Longer Rest

Core Sleep combines optimal nighttime hydration with a targeted blend of eight scientifically-backed ingredients, each chosen to help you fall asleep faster, sleep more deeply, and stay asleep longer.

The Formula:

  • L-Tryptophan (1000mg) - boosts serotonin and melatonin, helping you fall asleep faster and sleep better.

  • L-Theanine (200mg) - promotes relaxation, reduces stress, and helps you fall asleep faster while improving sleep quality without causing drowsiness.

  • L-Glycine (1000mg) - may lower core body temperature, helping you fall into deep and REM sleep faster, improve sleep quality, reduce daytime sleepiness, and boost next-day cognitive performance.

  • Ashwagandha (100mg) - Ashwagandha helps lower cortisol, supports natural stress rhythms, and can promote faster sleep onset with improved restorative sleep quality.

  • Valerian Root Extract 10:1 (75mg) - Valerian Root Extract may improve sleep quality, reduce time to fall asleep, increase total sleep time, and lessen anxiety and daytime sleepiness, leaving you feeling more refreshed on waking.

  • Vitamin B6 Pyridoxine (14MG) - Vitamin B6 supports amino acid metabolism to produce neurotransmitters that regulate sleep patterns and reduces neural excitation, aiding effective cognitive recovery during sleep.

  • Zinc Bisglycinate (2MG) - Zinc supports neurotransmitter function and healthy sleep, and may boost melatonin production - key for regulating sleep cycles -especially when deficiency is present.
