The routine

How the Calm Stack fits your whole day.

Ashwagandha steadies your energy through the day, magnesium eases tension as it winds down, and sleep support quiets the mind before bed. Calm that works around the clock — not just at night.

Through the day
Ashwagandha

It starts long before bedtime. Through a demanding day, 650 mg of organic ashwagandha root keeps your energy steady and composed — the calm that quietly keeps up with you.

As the day winds down
Magnesium powder

A scoop of 350 mg dual-source magnesium dissolves into water, lemon-lime. The body settles, the day's tension eases, and the evening finally slows.

Before bed
Sleep support

When it's time to let go, melatonin and a calming blend of L-Theanine, GABA, valerian and chamomile quiet a busy mind — so you drift off, and wake clear, not heavy.

The next morning
You wake a step ahead

Steady, unhurried, clear — not heavy. That's the whole promise, built the night before. Calmer evenings, easier mornings.
