One level scoop

3.4 g, dissolves clean in a glass of water. A ritual you’ll actually keep — not another pill to swallow.

Lightly lemon-lime

Natural lemon-lime flavor only. No sugar, no sweetener overload, no chalky aftertaste.

What to expect

A ritual that compounds.

Night 1

The ritual lands

The glass itself does work: one fixed cue that tells your body the day is done. The light lemon-lime is the reason you’ll actually keep it.

Week 2

Evenings soften

Winding down stops being a fight. Everyday muscle tension — from training, or from eight hours at a desk — starts easing off.

Week 4+

The baseline shifts

Magnesium stores replenish gradually, not overnight. Steadier evenings, easier mornings — keep the scoop where you can see it.

Questions

Asked, answered

When should I take it? +
One scoop (3.4 g) in 6–8 oz of water, once daily. It works best in the evening, 30–60 minutes before bed — as the fixed cue that ends your day. Consistency beats timing.
What does it taste like? +
Lightly lemon-lime — flavored with natural lemon-lime only. No sugar, no heavy sweeteners, and it dissolves clean, so no chalky sludge at the bottom of the glass.
Why two forms of magnesium? +
Citrate is one of the better-absorbed, gentler forms. Aquamin marine magnesium is drawn from seawater. Together they deliver 350 mg of elemental magnesium — 83% of your daily value — per scoop.
Will it make me groggy in the morning? +
No. There’s no melatonin and nothing sedative in the formula — magnesium supports your body’s own wind-down rather than knocking you out. You wake up clear.
Is it easy on the stomach? +
At one scoop a day, citrate is generally well tolerated — it’s the cheap oxide form that’s notorious for digestive drama. If you’re sensitive, start with half a scoop for the first few days.
Can I take it alongside medication? +
If you’re pregnant, nursing, have kidney issues, or take prescription medication — especially antibiotics or blood-pressure medication — check with your clinician first.
How does the subscription work? +
15% off every monthly delivery. Skip a month, change your date, or cancel anytime from your account.
