our story
Inspired by stillness
Serein is a rare word used to describe a quiet atmospheric moment — a sense of stillness that arrives as the day begins to soften.
We knew we'd found the right name because it reflected everything we wanted this brand to be.
A little calmer.
A little quieter.
A little more considered.
ingredients
Chosen with Purpose
We believe a thoughtful formula doesn't need to be complicated. Just three carefully chosen ingredients, each selected with a clear purpose.
Magnesium bisglycinate • Naturally derived L-theanine from green tea • Vitamin B6
Nothing more than we believe is needed.
formulation
Why these three?
The strength of a formula isn't about adding more. It's about choosing ingredients that complement one another.
Magnesium bisglycinate forms the foundation of the formula, supporting normal psychological and nervous system function.
Naturally derived L-theanine from green tea complements it, helping to support relaxation while maintaining a clear, focused state.
Vitamin B6 completes the blend, contributing to normal psychological function and helping reduce tiredness and fatigue.
Together, they create a formula where every ingredient has a purpose and works in harmony with the others.
