The Dirty Secret About Most Magnesium Supplements
Why you felt nothing the last time you tried magnesium
Most Supplements Use Magnesium Oxide
It's cheap to manufacture but has only 4% bioavailability. That means 96% of what you're paying for passes right through you without ever reaching your nervous system.
Your Body Can't Absorb What It Can't Recognize
Magnesium oxide isn't bound to anything your body knows how to use. Without a proper delivery system, even high doses become expensive waste.
See The Difference
Calm uses magnesium glycinate bound to a raw honey delivery system—the form clinically proven to cross into your nervous system and signal your brain it's safe to wind down.
94% Absorption Rate
Magnesium glycinate is chelated to amino acids your body already recognizes, allowing it to bypass digestive barriers and reach your cells.
KSM-66 Ashwagandha
The most clinically studied adaptogen for stress reduction, with 66 studies proving its efficacy for cortisol reduction and sleep quality.
Raw Honey Delivery System
Naturally prebiotic and antibacterial, raw honey primes your gut to maximize absorption of every active ingredient.
No Melatonin Dependency
Supports your body's natural sleep cycle instead of overriding it. Wake up refreshed, not groggy.

Finally, Magnesium That Works
As a neurologist, I understand why most magnesium supplements fail. Calm uses the right form with the right delivery. I recommend it to patients struggling with sleep.

The Science Actually Checks Out
I've dispensed thousands of magnesium supplements. Most are glorified placebos. The glycinate form in Calm is what I take myself and recommend to my family.

Science-Backed Results You Can Feel
Every claim we make is backed by peer-reviewed research. Magnesium glycinate has been studied extensively for its superior bioavailability, and KSM-66 ashwagandha holds 66 clinical studies proving its stress-reduction benefits. We don't hide behind proprietary blends—what's on the label is what's in the sachet.

Not All Magnesium Is Created Equal
Most supplements use cheap magnesium oxide because it's inexpensive to manufacture. The result? You absorb almost nothing. Here's how Calm compares to what you'll find on most shelves.

Questions About Magnesium Science
Everything you need to know about why magnesium form matters, how absorption works, and what makes Calm different from everything else on the shelf.
Still Have Questions?
Different magnesium compounds have vastly different absorption rates. Magnesium oxide (the most common form) has only 4% bioavailability—meaning 96% passes through you unused. Magnesium glycinate is chelated to amino acids, allowing 94% absorption and the ability to cross the blood-brain barrier to reach your nervous system.
Bioavailability studies measure how much of a compound reaches systemic circulation after ingestion. Magnesium glycinate's high absorption rate comes from its chelation to glycine, an amino acid your body readily absorbs through existing transport pathways.
Raw honey is naturally prebiotic and antibacterial, which primes your gut for optimal absorption. It also provides immediate fuel that helps transport active ingredients where they need to go. Plus, it makes Calm genuinely taste good—compliance matters for supplements.
Melatonin supplements can create dependency and disrupt your body's natural production over time. Calm supports your body's own sleep mechanisms through magnesium and ashwagandha, helping you fall asleep naturally without the groggy morning-after feeling.
Many people notice improved relaxation within the first few nights. However, magnesium levels build in your system over 2-4 weeks of consistent use, so the full benefits compound with time. Stick with it nightly for best results.
Calm is safe to take alongside most supplements. However, we recommend spacing it 2 hours from any medications that may interact with magnesium. Consult your healthcare provider if you're on prescription medications.
