The Science
Built around how your body actually works.
Your body has three moments every day where the right support changes everything: when you wake, when you eat, and when you sleep. X1 Day is designed for those moments.
Morning Fast™
Support for the fasting window.
Most mornings start with a choice: eat now, or hold off. Morning Fast is designed to make holding off easier. Formulated to be taken on an empty stomach, it supports hunger and craving control† so you can extend your morning fast comfortably and start the day feeling in control rather than distracted. No caffeine, so it works whether or not you drink coffee.
- Supports fasting + hunger control†
- Designed for an empty stomach
- Caffeine-free
Meal Activator™
Support for your first meal.
How your body handles your first meal sets the tone for the rest of the day. Meal Activator is taken before you eat and is formulated to support healthy glucose metabolism and insulin sensitivity† — helping your body use what you eat more efficiently, so meals fuel you instead of slowing you down.
- Supports healthy glucose metabolism†
- Supports insulin sensitivity†
- Caffeine-free
Deeper Sleep™
Support for recovery overnight.
Sleep is where the day's work gets consolidated. Deeper Sleep is a calming nighttime formula designed to help you relax, fall asleep faster, and stay asleep† — supporting the overnight recovery that lets you wake up better. Formulated without melatonin, so there's no next-day grogginess.
- Supports relaxation + falling asleep†
- Supports staying asleep†
- Melatonin-free
