Every Ingredient, Explained
The goal was never to make the strongest-looking sleep label. We wanted a simple formula with understandable ingredients, careful amounts, and a role that makes sense within a healthy bedtime routine.
Albion® Magnesium Bisglycinate
Provides 70 mg of the 90 mg. Magnesium bound to the amino acid glycine, a chelated form chosen because it is generally gentle and well tolerated. It's from Albion®, the same mineral maker behind our Multi.
Albion® Dimagnesium Malate
Provides the remaining 20 mg. Magnesium bound to malic acid. It's more concentrated than bisglycinate, so pairing the two keeps the scoop small and easy to mix.
L-Theanine — 25 mg
An amino acid naturally found in tea leaves. We kept it at a modest 25 mg as one part of the formula, rather than building the product around a single headline ingredient.
Under the Upper Limit
For ages 4–8, the upper limit for magnesium from supplements is 110 mg per day. One scoop provides 90 mg, so it stays under that limit on its own.
Ages 4+, One Scoop
One simple 2.2 g scoop for children ages 4 and older, in a Mixed Berry flavor sweetened with stevia.
No “Knockout” Promise
Calm + Sleep is not meant to replace healthy sleep habits or to promise sedation. It is intended as one thoughtful option within the bigger bedtime picture.

Why I Made This
As a board-certified pediatrician and a mom of seven, I know how tempting it is to look for one thing that will suddenly fix bedtime.
That isn’t how I think about sleep. Routine, environment, schedule, stress, and the child themselves all matter.
But I also understand why families sometimes want a simple, carefully dosed supplement that can become one part of a consistent evening routine.
So I wanted this formula to be understandable: magnesium in thoughtfully selected forms, a modest amount of L-theanine, one simple scoop, and no promises that a powder can replace healthy sleep habits.
That’s what Calm + Sleep is meant to be: support for the routine, not a shortcut around it.

Support the Routine — Not Replace It
Good sleep starts with the basics: a consistent schedule, a calm environment, and healthy bedtime habits. Calm + Sleep is designed to sit alongside those fundamentals, not compete with them.
Magnesium
An essential mineral involved in normal muscle and nervous-system function.†
L-Theanine
Included in a modest 25 mg amount as part of the overall bedtime formula.
Calm Routine
A supplement works best when it fits into a predictable evening rhythm rather than becoming the entire strategy.
Thoughtful Dosing
We prefer understandable amounts and a clear purpose over a long list of trendy bedtime ingredients.

Frequently Asked Questions
What age is Calm + Sleep for?
Ages 4 and up: 1 scoop daily as part of the evening routine.
How much magnesium is in one scoop?
One scoop provides 90 mg elemental magnesium: 70 mg from Albion® magnesium bisglycinate chelate and 20 mg from Albion® dimagnesium malate.
How much L-theanine is in one scoop?
One scoop contains 25 mg L-theanine.
Why use two forms of magnesium?
Both forms come from Albion®. Magnesium bisglycinate chelate provides most of the magnesium and was chosen because chelated magnesium is generally gentle and well tolerated. Dimagnesium malate is more concentrated, so pairing the two keeps the scoop smaller. Together they provide 90 mg elemental magnesium per scoop.
Is this meant to make my child fall asleep?
No product should be presented as a switch that turns sleep on. Calm + Sleep is designed to support a calm evening routine, not replace healthy sleep habits or evaluation of persistent sleep concerns.
Can my child take Calm + Sleep with the Children's Multi-Vitamin?
Yes. Our Children's Multi-Vitamin and Healthy Brain Chews are designed as daily essentials that work together, and Calm + Sleep is an as-needed addition.
Both Calm + Sleep and the Multi contain magnesium. For children ages 4–8, a full serving of each adds up to 140 mg, a bit above the 110 mg upper limit for supplemental magnesium.
That limit exists mainly because extra magnesium can loosen stools. It is not a sign of danger. Both of our products use Albion® chelated magnesium, a form chosen because it is generally gentle on the stomach.
If you’d like to stay under the limit, give half a scoop of Calm + Sleep on those nights (95 mg total). Kids 9 and up are well within the limit.
When should Calm + Sleep be used?
Calm + Sleep is designed to fit into a consistent evening routine. Mix 1 scoop of the Mixed Berry powder into water or your child’s favorite drink in the evening. A supplement does not replace healthy sleep habits or an evaluation of persistent sleep concerns.
Why a powder?
A powder keeps the formula simple and makes one-scoop dosing easy to build into an evening routine. It has a Mixed Berry flavor, sweetened with stevia, and mixes into water or your child’s favorite drink.
When should I talk with my child’s pediatrician?
If your child has persistent or significant sleep problems, takes medication, has a medical condition, or you are unsure whether a supplement is appropriate, talk with your child’s pediatrician or another qualified healthcare professional.
