Most-deficient mineral
A note from Dr. Schrock
"Most Americans are chronically deficient — and don't know it."
If I had to pick a single supplement that benefits the largest percentage of patients walking into my office, it would be magnesium glycinate. The numbers are striking: depending on the survey you read, somewhere between 50 and 80 percent of American adults consume less magnesium than the RDA. Soil depletion, processed food, chronic stress, and certain medications all chip away at the body's stores.
The symptoms of subclinical deficiency are easy to miss because they overlap with everything else — light sleep, muscle cramps, restless legs, tension headaches, anxious feelings, constipation, blood-pressure creep. The form matters: magnesium oxide is cheap and largely laxative; citrate is a step up; glycinate is the form I reach for because it absorbs cleanly, doesn't upset the gut, and the glycine itself supports calm and sleep. It's the closest thing to a foundational supplement I recommend.
What's inside
These products support healthy magnesium levels, normal muscle and nerve function, and restful sleep. They are not intended to diagnose, treat, cure, or prevent any disease. Always consult your healthcare provider before beginning any supplement regimen, especially if you take prescription medication.

Understanding magnesium
Four reasons magnesium is the most foundational mineral.
Magnesium is not a niche supplement. It is a co-factor for hundreds of enzymes that govern energy, nerves, muscles, and sleep — and most adults are running on less than the body needs.
-
300+ enzymatic reactions
Magnesium is required for ATP production, DNA repair, neurotransmitter synthesis, protein folding, and blood-glucose regulation — among hundreds of others. Run low on magnesium and dozens of systems quietly slow down.
-
Glycinate vs oxide bioavailability
Magnesium oxide is roughly 4 percent absorbed and mostly acts as a laxative. Glycinate is chelated for clean absorption into the bloodstream — which is why it is the form clinicians prefer for daily use.
-
Sleep & nervous system
Magnesium calms the NMDA receptor and supports GABA tone — the brain's primary inhibitory system. Patients consistently report deeper sleep and quieter minds within two to four weeks of consistent dosing.
-
Muscle relaxation
Calcium contracts muscles; magnesium relaxes them. Adequate magnesium reduces cramps, tension, restless legs, and the kind of jaw and shoulder tightness most people don't realize they're carrying.

Why magnesium matters
"Most Americans are chronically deficient in magnesium and don't know it — and the symptoms hide in plain sight."
Light sleep, leg cramps at night, that tight band across the shoulders, the slow creep of blood pressure, restless evenings — patients describe these symptoms one at a time and treat them one at a time. Underneath, the same mineral is often missing. Soil depletion, processed food, chronic stress, and several common medications all pull magnesium out of the body faster than the modern diet replaces it.
The form matters more than most people realize. Magnesium oxide is what you find in cheap pharmacy bottles — it's mostly laxative. Glycinate is what clinicians actually use because it absorbs into the bloodstream and the glycine itself supports calm and sleep. Most patients feel the difference within two to four weeks.

Common questions
Magnesium — common questions.
Glycinate vs citrate vs oxide — what's the difference?
Oxide is the cheapest and least absorbed (about 4 percent) — it mostly works as a laxative. Citrate is better absorbed (around 25–30 percent) and still has a mild laxative effect, making it useful for constipation. Glycinate is chelated to glycine for clean systemic absorption, is gentle on the gut, and the glycine itself supports calm and sleep — which is why it's the form most clinicians prefer for daily use.
What's the typical daily dose of magnesium glycinate?
Most adults do well on 200–400 mg of elemental magnesium per day, ideally split into two doses or taken in the evening. Our formulas deliver clinical doses when taken as directed. Start lower if you're new to it and titrate up.
Will magnesium glycinate cause loose stools?
Very rarely — that's the main advantage of glycinate over oxide or citrate. Glycinate is absorbed before it reaches the colon, so it doesn't pull water into the gut the way other forms do. If you're trying to ease occasional constipation, magnesium citrate is the better pick.
Can I take magnesium for sleep?
Yes — this is one of the most common reasons patients pick up magnesium glycinate in the first place. Take it 30–60 minutes before bed. Magnesium supports GABA tone and helps relax muscles, both of which translate to deeper, quieter sleep within two to four weeks for most people.
Will magnesium interact with my medications?
Magnesium can interact with certain antibiotics (tetracyclines, fluoroquinolones), bisphosphonates, and some blood-pressure and heart medications — usually by affecting absorption. The fix is timing: separate magnesium from those prescriptions by two to four hours. Loop in your prescribing provider before adding it to any chronic regimen.
