Low Magnesium Has Been Linked To Sudden Cardiac Death.† Half Of Adults Are Not Getting Enough.

A landmark study followed 14,000+ adults for more than a decade. Those with the lowest magnesium levels had up to nearly double the risk of sudden cardiac death compared to those with the highest.† Magnesium runs your heartbeat, and most people never find out they are low until something feels wrong. Here is how to fix it, starting tonight.

Why It Matters

You cannot feel a magnesium deficiency. You can only feel what it does to you.

Magnesium runs your heart rhythm, your nervous system, and your sleep. Studies have linked low levels to serious cardiovascular risk, and nearly half of adults fall short without ever knowing it.†

The symptoms everyone blames on stress or age

Low magnesium hides in plain sight. Check the ones that sound like you:
  • You wake at 3am and cannot fall back asleep
  • Wired but exhausted, cannot switch your brain off at night
  • Muscle cramps or twitches, especially at night
  • Stress hits harder than it used to
  • Brain fog and the 3pm energy crash
  • Restless, on-edge, or anxious for no clear reason
Checked two or more? You are likely in the 48% who do not get enough.†

Refill it, and here is what comes back

What's Inside · The Source & The Science

4 ingredients. Where they come from, and how they work.

No proprietary blends, no mystery. The right form at a real dose, plus the two cofactors your body needs, and exactly what each one does.

Magnesium Glycinate
01 · The Foundation
Magnesium Glycinate
400 mg elemental / serving
Where it comes from

An essential mineral drawn from the earth and sea, one of the most abundant on the planet, yet one of the most stripped out of modern food. We use the glycinate form: magnesium bound to the amino acid glycine.

Why you are low

Modern soil is depleted, processed food is stripped of it, and stress, caffeine, and alcohol flush it out of your body faster than you replace it.†

How it works

Bound to glycine, the magnesium is chaperoned through your gut wall intact, absorbed like an amino acid instead of getting flushed like cheap oxide. That is why glycinate absorbs where oxide fails.†

Glycine
02 · The Carrier
Glycine
The carrier amino acid
Where it comes from

The smallest amino acid, concentrated in collagen-rich foods like bone broth and connective tissue, the exact foods almost nobody eats enough of anymore.

Why you are low

Your body makes some, but not enough under chronic stress, and modern diets deliver very little of it.

How it works

It is the carrier that ferries magnesium across the gut, and a calming amino acid in its own right, studied for supporting deeper, more restful sleep.†

Vitamin B6 (P-5-P)
03 · The Activator
Vitamin B6 (P-5-P)
Absorption cofactor
Where it comes from

A vitamin found in whole foods like fish, poultry, and bananas, included here in its active P-5-P form your body can use directly.

Why you are low

Commonly low in processed diets, and your body burns through more of it under stress.

How it works

The cofactor that helps magnesium actually cross into your cells and get used. Without enough B6, much of the magnesium you take is simply wasted.†

Zinc
04 · The Partner
Zinc
Utilization cofactor
Where it comes from

An essential trace mineral from the earth, concentrated in oysters, red meat, and pumpkin seeds.

Why you are low

One of the first minerals depleted by stress, heavy sweating, and hard training.

How it works

It works alongside magnesium in your stress-response and recovery pathways, supporting a healthy stress response and muscle recovery from a second angle.†

67 and skeptical, but my doctor said my magnesium was low. Started this instead of a script and my resting heart rate settled a few points. Sleeping better too. Wish I'd known sooner.

Was waking up at 3am every night for years. Two weeks on this and I sleep straight through. Didn't think a mineral would be the thing that fixed it.

Tried the drugstore gummies, felt nothing. This is completely different, calmer in the evenings and not dragging in the morning. The glycinate really matters.

As a nurse I check labels. Most magnesium is oxide at a token dose. 400mg elemental as glycinate with B6 is a formula I actually recommend and take myself.
