The Origin Story

I didn't plan to build a supplement company. I planned to sleep.

I spent sixteen years climbing a high-demand civilian career while serving as a Coast Guard Reservist. I deployed in 2019. In November 2023, I went on continuous active-duty orders and never returned to the civilian chapter. My nervous system didn't get a vote on any of it.

Here's what nobody tells you about running two full tracks at once for a decade: your body keeps you online by staying in low-grade sympathetic activation. Mildly elevated cortisol. Mildly elevated heart rate. Mildly compressed sleep. The reason you don't notice is that "mild" feels normal when it's been your baseline for years.

The first sign for me was sleep. I'd get in bed at a reasonable hour. No phone, no TV, nothing keeping me up. I'd fall asleep — and then somewhere between 1 and 2 AM, I'd be awake again. Not from a dream. Not from a noise. Just awake, heart rate already up, the rest of the night spent staring at the ceiling cataloging tomorrow's problems.

I tried the usual things. Melatonin. Cutting caffeine. A meditation app or two. Cold showers. Breathwork. Some of it helped. None of it fixed it. I was given other options that came with their own list of side effects — some of which I experienced. My nervous system was stuck, and no single habit was going to tell it to stand down.

That's when I started actually reading the research on what nervous system regulation depends on at the cellular level. And I found a pattern I hadn't expected: your nervous system runs on minerals. Specifically, it runs on magnesium — which is required for over 300 enzymatic reactions in the body, including every single one that governs muscle relaxation, GABA receptor activity, and the parasympathetic downshift you need to actually rest.

Chronic stress depletes magnesium faster than most people replace it. Low magnesium amplifies the stress response. More stress depletes more magnesium. It's a loop, and habits alone don't break it if the mineral floor is too low.

So I tried every magnesium glycinate on the market. Most were underdosed — 100 mg or 150 mg per serving when the research uses 250-400 mg. Some had fillers I didn't want in my body. A few were well-formulated but cost $60 a bottle for a 30-day supply, which made no sense for a mineral that costs pennies to produce correctly.

After about six months of that, I stopped looking and started formulating my own. What you're reading about is the result.

The Formulation

One ingredient. Every dose disclosed.

Three capsules before bed. No proprietary blends. No fillers. Just the mineral, the dose the research actually uses, and the chelation form your body can actually absorb.

Magnesium Glycinate

275 mg Elemental · 65% DV

Two thousand five hundred milligrams of magnesium glycinate per serving, delivering 275 mg of elemental magnesium — the clinical dose the sleep and nervous system research actually uses. Most drugstore magnesium supplements deliver half of that or less.

Glycine Carrier

The Calming Amino Acid

The glycinate form means the magnesium is chelated to glycine — an amino acid that independently supports GABA activity and sleep quality. You get two mechanisms from one compound. Glycinate is also gentle on the stomach, unlike magnesium citrate or oxide.

Clean Capsule

No Fillers · Vegan

Hypromellose (vegetable capsule), a trace amount of magnesium stearate for flow, silicon dioxide, and rice flour. That's the entire supporting cast. No artificial colors, no dyes, no binders, nothing the formula doesn't need.

What the Research Says

The mineral your nervous system runs on.

Magnesium is one of the most-studied minerals in human physiology. Here's what the peer-reviewed literature actually shows — plain language, direct links, no cherry-picking.

Magnesium is required for over 300 enzymatic reactions

A 2015 review in Nutrients cataloged the roles magnesium plays in human biochemistry — from energy production to muscle contraction to neurotransmitter synthesis. Chronic insufficiency is linked to sleep disturbance, muscle cramping, and elevated stress response. Over 40% of U.S. adults don't meet the recommended daily intake.

Magnesium glycinate is more bioavailable than oxide or sulfate

A 2019 comparative review in Nutrients found that chelated forms of magnesium — including glycinate — showed significantly better absorption and retention than inorganic forms like oxide and sulfate. Glycinate was also noted for being gentler on the digestive system, which matters if you're taking it before bed.

Magnesium supplementation supports sleep quality in adults with insomnia

A 2012 double-blind placebo-controlled trial found that daily magnesium supplementation improved subjective measures of insomnia — sleep time, sleep efficiency, and early-morning awakening — and lowered serum cortisol in older adults. The dose used was within the range our formula delivers.

Glycine itself supports sleep quality independently of magnesium

Multiple trials — including work published in Sleep and Biological Rhythms — have shown that glycine supplementation before bed improves subjective sleep quality and reduces fatigue the following day. In the glycinate form, you're getting both mechanisms at once.

Honest Answers

You're going to ask.

The ten questions we hear most — answered directly, without marketing fluff. If you have one that isn't here, email us and we'll answer personally.

Why glycinate instead of oxide or citrate?

Because absorption matters. Magnesium oxide is cheap, it's what most drugstore brands use, and it's the form that passes through you mostly unabsorbed. Citrate is better absorbed but is best known for its laxative effect — not what you want before bed. Glycinate is magnesium chelated to glycine, which gives you two benefits at once: better absorption and a calming amino acid that independently supports GABA activity. Every sleep researcher I've read specifically recommends glycinate.

When should I take it — morning or night?

Night. Specifically, 30-60 minutes before you want to be asleep. The calming effect builds as your body absorbs it, and taking it earlier in the day means you're burning the effect during waking hours when you don't need it. Three capsules with a small amount of water.

How long before I feel it?

Most people notice a difference in the first 10-14 nights. If you've been running hot for a long time — chronically stressed, poor sleep for years — it can take three weeks before the cumulative effect lands, because your body is rebuilding a mineral reserve that got depleted. Stay consistent through week three before you judge it.

Can I take it with other supplements?

Magnesium plays well with most supplements, but don't take it at the exact same time as a calcium or zinc supplement — those three minerals compete for absorption in the gut. If you're stacking, space them out by a few hours. Magnesium pairs particularly well with any of the other formulas in the Astral & Root line.

Is it safe with medications?

Magnesium can interact with certain medications — including some antibiotics, diuretics, and blood pressure drugs — by affecting how they're absorbed. If you're on any prescription medication, talk to your healthcare provider before starting. The most common advice is to space magnesium and medications a couple of hours apart, but your doctor should make that call based on your specific situation.

What about pregnancy or nursing?

Talk to your OB or midwife before starting any new supplement during pregnancy or nursing. Magnesium is generally considered safe and is often recommended during pregnancy, but dosing and timing should be cleared by your provider who knows your full situation.

Will it make me drowsy during the day?

Not if you take it at night, which is the protocol we recommend. Magnesium glycinate isn't a sedative — it supports your nervous system's natural ability to downshift. Taken at night, it helps you sleep. Taken during the day, it just becomes part of your baseline magnesium level. Either way, you won't feel foggy or sluggish in the morning.

How is this different from the magnesium at my local drugstore?

Three things: form, dose, and transparency. Drugstore magnesium is usually magnesium oxide (poorly absorbed). It's usually underdosed (100-150 mg per serving). And the labels rarely disclose the elemental magnesium content clearly. Our formula is glycinate, delivers 275 mg of elemental magnesium per serving, and every gram is disclosed on the label.

Is this the same magnesium that's in the Descend Ritual?

Yes. The Descend Ritual includes a 30-day supply of this exact formula alongside Ayurvedic Complex and the Audicin Neuroacoustic Headband. If magnesium alone is what you need, this bottle is the entire answer. If you need the full three-layer protocol, Descend is built for that.

What if it doesn't work for me?

Thirty-day money-back guarantee. No questions, no return gauntlet. Email us, we refund the order, and we keep the conversation open in case you want to try a different approach later. Veteran-owned means we answer to you, not a boardroom.

The Guarantee

Thirty nights. Your money back if it doesn't move the needle.

Take it for thirty nights. Three capsules, 30-60 minutes before bed. Stay consistent. If at the end of the bottle you don't feel the shift — if your sleep hasn't improved, if your nervous system doesn't feel more regulated, if the 1 AM wake-ups are still there — email us and we'll refund the order. No questions, no return gauntlet, no retention call.

That's the deal. Veteran-owned means we answer to you, not a boardroom.

If magnesium alone isn't enough — Descend is waiting.

For most people, Magnesium Glycinate is the foundation and the foundation is all they need. But some people have been stuck in sympathetic dominance for so long that one mineral won't finish the job. If that's you — if magnesium gets you eighty percent of the way back but there's still a part of you that can't quite come down — The Descend Ritual pairs this exact magnesium with Ayurvedic Complex for cortisol regulation and the Audicin Neuroacoustic Headband for direct neurological entrainment. Three layers, one nervous system, thirty nights to reset your baseline.
