SEREIN No.1 - Calm Clarity
SEREIN No.1 - Calm Clarity
SEREIN No.1 is a considered daily blend of magnesium bisglycinate, naturally derived L-theanine from green tea and vitamin B6.
A simple daily ritual created to support calm, clarity and a steadier way to move through the day — without heaviness or drowsiness.
Simple to take daily. Intentionally understated. Made for moments when life feels loud.
Every milligram of magnesium comes from bisglycinate
No lower-cost forms are added to bulk out the formula.
We chose magnesium bisglycinate because it's a highly regarded form, selected for its absorption profile and suitability for everyday use.
Naturally sourced L-theanine from green tea
We use naturally derived L-theanine from green tea, not a synthetic alternative, because thoughtful formulation begins with careful sourcing.
Designed to complement one another
Magnesium bisglycinate supports relaxation, naturally derived L-theanine helps promote calm focus, and vitamin B6 contributes to normal psychological and nervous system function. Together, they've been carefully chosen because each ingredient complements the others, creating a balanced formula where every ingredient has a clear purpose.
Quality without compromise
Every decision behind SEREIN No.1 has been made with the same level of care — from the ingredients we choose and where we source them, to manufacturing in a HACCP & GMP-certified UK facility. Because quality isn't defined by a single ingredient. It's reflected in every step of the process.
