Build a calmer close to the day. This bedtime-focused magnesium gives you 350 mg of elemental magnesium in a gentle glycinate chelate, with zero fillers and a public certificate of analysis. Magnesium supports normal muscle and nerve function and helps the body produce energy.[1]
Take 2 capsules with water about 30 minutes before bed, with or without food.
The goal is not another complicated wellness project. It is a repeatable signal that the day is ending: 350 mg elemental magnesium in two capsules, a gentle glycinate chelate, zero fillers, and a public certificate of analysis.
What the research says
Promising for sleep support. Not a sleeping pill.
A 2025 randomized, placebo-controlled trial of magnesium bisglycinate—not this specific product—found a modest improvement in self-reported insomnia severity after four weeks.[2] Earlier trials also reported improvements in some sleep measures,[4] but a systematic review rated the overall evidence low to very low quality and called for better research.[3]
Our honest read: magnesium can be a sensible part of a nighttime routine, especially when magnesium intake is low, but it is not a guaranteed fix or a treatment for insomnia.
350 mgelemental magnesium per 2-capsule serving, equal to 83% Daily Value.

Zero fillersNo magnesium oxide, fillers, or anti-caking agents.

What it gives your evening
A clear wind-down cue
Two capsules about 30 minutes before bed turn “I should relax” into one easy, repeatable step.
Sleep support without hype
Clinical research on magnesium and sleep is promising but not conclusive. We show you both the findings and the limits.[2][3]
Normal muscles and nerves
Magnesium is essential for normal muscle function and nerve signaling.[1]
Everyday energy processes
Your body requires magnesium for energy production, including glycolysis and oxidative phosphorylation.[1]
350 mg that is easy to compare
We lead with elemental magnesium—the amount that counts toward Daily Value—not the heavier compound weight.
A formula you can inspect
Glycinate chelate, a plant-based capsule, zero fillers, no magnesium oxide, and a public COA.
Why glycinate instead of oxide?
Magnesium typeBest fitSimple explanation
Magnesium glycinateA gentle daily magnesium routine, especially for evenings.Magnesium is paired with glycine in a chelated form. This is the form used here.
Magnesium oxideUsed in some formulas for different goals.This formula intentionally does not use magnesium oxide.
Magnesium citrateAnother common supplemental form.It can fit other routines, but it is not the form used here.
Elemental magnesium is the number that matters
Magnesium compounds have both a total compound weight and an elemental magnesium amount. The elemental amount is the magnesium counted toward the U.S. Daily Value. This label clearly shows 350 mg elemental magnesium, equal to 83% DV.
Make it the closing step
Take 2 capsules with water about 30 minutes before bed, with or without food. Pair it with the same simple cues each night—dim the lights, put the phone down, and let the routine do less work.
Frequently asked questions
Does magnesium glycinate help you sleep?
Research is promising, not definitive. A 2025 randomized trial of magnesium bisglycinate found a small improvement in self-reported insomnia severity, while a 2021 review judged the wider evidence low to very low quality.[2][3]
That is why we position this as nutritional support for a calmer nighttime routine—not as a sleeping pill or an insomnia treatment. The Sleep Foundation offers a plain-language overview of the current evidence.[5]
What is magnesium glycinate?
Magnesium glycinate is magnesium paired with glycine in a chelated form. This product provides 350 mg elemental magnesium per serving.
What does elemental magnesium mean?
Elemental magnesium is the actual magnesium amount counted on the Supplement Facts label. It is the clearest number to compare between products.
When should I take it?
Take 2 capsules with water about 30 minutes before bed, with or without food. Follow the label unless your healthcare professional advises otherwise.
What is HPMC?
HPMC stands for hydroxypropyl methylcellulose. It is a plant-based capsule material and a common alternative to gelatin.
Does this formula use fillers?
No. It uses magnesium glycinate chelate in a plant-based capsule, without magnesium oxide, fillers, or anti-caking agents.
Is the lab documentation available?
Yes. The certificate of analysis is publicly available so you can review the testing documentation before deciding.

What to Look for in a Certificate
A useful report should help you match the document to your bottle and see what was tested. FDA quality guidance centers on identity, purity, strength, composition, and limits on contaminants. Read the FDA quality guidance ↗
01
Lot or batch
The report identifier should match the lot or batch printed on your bottle.
02
Product identity
Look for the named product or material and the test or examination method used.
03
Strength and composition
When potency is tested, compare the actual result with the specification or labeled amount.
04
Purity and safety
Look for contaminant or microbial limits, actual results, and a clear pass or specification.
Available 2-page COA
Magnesium Glycinate – Batch MN-MGG-2025-001
Compare the batch on the report with the lot or batch printed on your bottle. Page 1 covers identity and physical testing; page 2 covers assay, purity, and safety.
Certificates are lot-specific. A report for one lot does not automatically describe a later production run, and a certificate evaluates product specifications – not clinical effectiveness.
How to Use Magnesium Glycinate
Start with the product label, then compare it with public guidance. Label directions, nutrient targets, and research doses answer different questions.
What the label says2 capsules daily
The current label says adults take 2 capsules daily with water. It does not require bedtime or food.
Per capsule: 175 mg elemental magnesium
What public guidance says310-420 mg total/day
NIH adult RDAs range from 310 to 420 mg daily, depending on age and sex, and count magnesium from food, drinks, supplements, and medications. The adult upper limit is 350 mg daily from supplements and medications unless a healthcare professional recommends otherwise.
Why the numbers differTotal intake is not the same as a supplement limit
This product supplies 350 mg supplemental magnesium in the two-capsule serving. The RDA includes every source; the supplemental upper limit does not include magnesium naturally present in food. Evening timing is an optional routine choice, not the label direction.
A simple label-led routine
1
Take two capsules
Use the complete label serving once daily.
2
Use water
The label calls for water and does not require food.
3
Choose a consistent time
Morning or evening can work. If a wind-down routine is your goal, evening is a practical choice rather than a dosage requirement.
Use the label as the default
Use the label as the default. The NIH numbers explain total nutritional needs and the supplemental upper limit; they are not instructions to stack this product with other magnesium supplements.
Check before use
Ask a healthcare professional before use if you are pregnant, nursing, taking medication, have kidney disease, or manage a medical condition.
Do not combine with other magnesium supplements without checking your total supplemental intake.
Magnesium can interact with some antibiotics, bisphosphonates, and other medicines.
Stop use if you experience a concerning reaction.
Keep out of reach of children.

This magnesium helps us sleep and soothes our 12-year-old's nerves. Magnesium supplements today can have heavy metal contaminants, but USA Medical posts independent lab tests of their magnesium showing its purity.
