The Mechanism
The Eight-Active Wind-Down Protocol
1
Take
Two vegetarian capsules with a glass of water before bedtime. No new habit required beyond what you already do.
2
Relax
L-theanine and Serenzo™ begin supporting a calmer mental state, helping quiet the noise of the day.
3
Unwind
Valerian, lemon balm, lavender, and hop flower work together to ease the body toward its natural rest state.
4
Rest
Magnesium and Cherry PURE® complete the stack, supporting the body through the night for a more restorative sleep cycle.
The result is a layered approach to pre-sleep support, calmer thoughts, relaxed muscles, botanical evening signals, and a gentler transition into rest, all from two capsules and a glass of water.
The Science
Why switching off at night is harder than it should be
Most adults struggle to wind down not because of one problem but four overlapping ones. Sleep Well addresses each with a targeted active in the same pre-sleep capsule.
01
Mental Overactivity
Racing thoughts at bedtime are one of the most common barriers to falling asleep. L-theanine helps support a calmer, less reactive mental state heading into the night.
02
Stress Tension Carry-Over
Daily stress that does not resolve by evening keeps the body in an alert state. Serenzo™ orange oil and lemon balm are included to help support the shift away from that tension.
03
Missing Evening Botanicals
Valerian root, hop flower, and lavender have centuries of traditional use supporting restful sleep. Most single-ingredient supplements include only one; Sleep Well includes all three at meaningful doses.
04
Mineral and Recovery Gaps
Magnesium is involved in hundreds of physiological processes. Low intake can compromise the body's ability to relax muscles and prepare for restorative rest. Each serving contributes 16% of the daily NRV.
Key ingredients
