Sleep Isn't Just Rest. It's Recovery.
Stack Labs Sleep Stack combines four carefully selected, science-backed ingredients to help you fall asleep faster, stay asleep longer, and wake feeling refreshed. No unnecessary fillers. No overcomplicated formulas. Just everything your body needs for deeper, more restorative sleep.
Every ingredient has a purpose. Nothing has been added simply to fill a label.
The Four-Ingredient Stack
Magnesium Glycinate
Supports muscle relaxation and helps prepare your body for deep, restorative sleep.
Glycine
Helps lower core body temperature and supports deeper, higher-quality sleep throughout the night.
L-Theanine
Promotes a calm, relaxed mind without causing next-day drowsiness.
Apigenin
A natural flavonoid that supports relaxation and helps you fall asleep more easily.
Wake Up Ready.
Better sleep changes the way you show up the next day. Sleep Stack is designed to support calm, consistent, restorative sleep so you can wake feeling clearer, sharper, and more prepared.
"We believe better sleep doesn't come from adding more ingredients. It comes from choosing the right ones."

Less Ingredients. Better Results.
Why These Four Ingredients Work Better Together
Great sleep isn't driven by a single ingredient—it's the result of multiple biological processes working together. Sleep Stack combines four complementary ingredients that support relaxation, calm the mind, help regulate the body's natural sleep cycle, and promote deeper, more restorative sleep. Each ingredient has a distinct role, but together they create a more complete sleep solution than any one ingredient alone.
