CHOOSE.
Take your serving with a meal and a glass of water, as the label directs, or as your healthcare professional tells you.
02 · Take three capsules
TAKE.
A serving of pr1mebody magnesium glycinate is 3 capsules a day, so one bottle of 90 lasts 30 days; do not exceed the recommended daily dose.
03 · Count your other magnesium
COUNT.
Add up magnesium from other supplements and from medicines such as antacids and laxatives before you start, because the NIH upper limit counts supplements and medicines together.
04 · Store it with care
STORE.
Keep the bottle in a cool, dry place out of reach of children, and do not use it if the safety seal is damaged or missing.
What pr1mebody magnesium glycinate is
This is a food supplement for adults, sold as veggie capsules.
Read the details: what pr1mebody magnesium glycinate is
A serving is three capsules, and the label lists 360 mg of magnesium per serving as magnesium glycinate (bisglycinate); a bottle holds 90 capsules, which is 30 servings.
The label lists two other ingredients: the capsule shell, made of hydroxypropyl methylcellulose (a plant-based material), and magnesium stearate from a vegetable source. Those are the only other ingredients on the label.
Glycinate and bisglycinate are usually two names for one compound, magnesium bound to two glycine molecules. PubChem files it as Magnesium Glycinate and lists magnesium bisglycinate and magnesium diglycinate as synonyms. Our guide to types of magnesium explains why labels use different names.
Read this first: 360 mg is above the NIH upper limit
The label dose, 360 mg of magnesium per serving, is above the 350 mg a day that the US National Institutes of Health sets as the upper limit for adults for magnesium from supplements and medicines.
Read the details: read this first: 360 mg is above the nih upper limit
It is also 96% of the 375 mg EU reference value for magnesium (Regulation (EU) No 1169/2011), so a single serving is close to the full reference amount.
The NIH limit counts supplements and medicines, not magnesium in food, and its consumer fact sheet says not to go above it unless a health care provider recommends it. High intakes from supplements can cause diarrhea, nausea and abdominal cramping, and the risk of harm rises with kidney problems because the body clears less magnesium.
Other bodies draw the line elsewhere. The NHS says 400 mg or less a day from supplements is unlikely to cause harm, while the EFSA upper level of 250 mg is stated for readily dissociable magnesium salts and compounds like magnesium oxide and does not name glycinate, so we cannot say how it applies here.
If you take any other magnesium, have kidney problems or take medicines, ask a doctor first. If you want a lower evening dose, our Tri-Mag Night provides 200 mg.
Is it for you? Who should skip it or ask first
It suits adults who want a glycinate capsule with one active ingredient and the amount printed plainly, and who are comfortable taking three capsules a day.
Read the details: is it for you? who should skip it or ask first
It is a supplement, not a replacement for a varied diet: the NHS says you should be able to get all the magnesium you need from a balanced diet, with spinach and nuts among the good sources.
Skip it, or ask a doctor first, if you are pregnant, nursing, under 18, taking medication or other products that contain magnesium, or have a medical condition, including kidney disease. That is the warning printed on the label.
Medicines matter here. The NIH says magnesium may interact with oral bisphosphonates and with tetracycline and quinolone antibiotics, and that diuretics and proton pump inhibitors can affect magnesium status. It suggests at least 2 hours between magnesium and a bisphosphonate, and taking those antibiotics at least 2 hours before or 4 to 6 hours after a magnesium supplement.
How to read the 360 mg on a magnesium label
Magnesium is only part of any magnesium compound by weight.
Read the details: how to read the 360 mg on a magnesium label
Using formula weights from PubChem, glycinate is about 14% magnesium, trimagnesium dicitrate about 16% and magnesium oxide about 60% (our arithmetic), so 1,000 mg of glycinate compound is only about 141 mg of magnesium.
The NIH explains that a Supplement Facts panel declares elemental magnesium, not the weight of the whole compound. We read the 360 mg here as the magnesium amount per serving, so compare it with other products on that number and not on capsule size.
Our magnesium glycinate dosage guide sets out how the limits compare across sources.
A bottle is 30 servings, and packs of 1, 3, 5 or 12 bottles give 30, 90, 150 or 360 servings; the pack table shows the cost per serving for each.

EU-authorised wording for magnesium
Wording authorised in the EU/GB register, not evaluated by the US FDA. These statements describe the mineral magnesium, not a result we promise from this bottle, and the register allows them only for a food that is at least a source of magnesium, which Regulation (EU) No 1169/2011 sets at 15% of the reference value under its general rule; three capsules provide 96% of that value on the label amount.
- Magnesium contributes to a reduction of tiredness and fatigue.
- Magnesium contributes to normal functioning of the nervous system.
- Magnesium contributes to normal psychological function.
- Magnesium contributes to normal muscle function.
- Magnesium contributes to electrolyte balance.
- Magnesium contributes to normal energy-yielding metabolism.

Before you order
What a bottle asks of you, and what it does not promise
A daily routine with a stated dose, no promised result, and a few things worth watching.
01
A simple daily routine
Take three capsules a day with a meal and a glass of water, and a bottle lasts 30 days. The NIH fact sheet gives no advice on time of day or on food, so the label directions are your guide.
02
Your stomach is the first thing to watch
High intakes of magnesium from supplements can cause diarrhea, nausea and abdominal cramping, according to the NIH, and the label says to stop use if you have an adverse reaction. In one small crossover trial of 12 people after ileal surgery, the glycinate form was better tolerated than oxide, but we found no head-to-head tolerance trial in healthy adults.
03
What the research reports
A 2025 randomized trial of 155 adults with self-reported poor sleep found a small difference in Insomnia Severity Index scores after four weeks of 250 mg of elemental magnesium as bisglycinate, and a 2026 evidence summary of 12 randomized trials rated the certainty low to very low; our magnesium for sleep guide covers the numbers. The trial dose was 250 mg, below the 360 mg here, so neither study tells you what this bottle will do.
04
No promised result
We make no promise about how you will feel, and you may notice nothing. The NIH recommended intake for adults is 310 to 420 mg a day from food and supplements combined, and the NHS says a varied diet can provide the magnesium you need.
Magnesium glycinate vs citrate vs oxide
Three common forms side by side, so you can see where glycinate sits, using only what the sources we read report.
Glycinate (bisglycinate)
Citrate
Oxide
What it is
Glycinate (bisglycinate)
Magnesium bound to two glycine molecules
Citrate
Magnesium with citric acid (PubChem's record is trimagnesium dicitrate)
Oxide
Magnesium bound to oxygen (MgO)
Magnesium by weight
Glycinate (bisglycinate)
About 14%
Citrate
About 16% (for trimagnesium dicitrate; other citrates differ)
Oxide
About 60%
Absorption evidence
Glycinate (bisglycinate)
Mixed: better than oxide on a urine measure in a 46-person, 60-day trial of an amino-acid chelate, but no plasma rise within 6 hours in a 40-person industry-funded study
Citrate
NIH: tends to be more bioavailable than oxide; highest blood magnesium in the 60-day trial
Oxide
NIH: tends to be less bioavailable than citrate; no difference from placebo in the 60-day trial
Digestive tolerance
Glycinate (bisglycinate)
Better tolerated than oxide in a 12-patient trial after ileal surgery; no head-to-head data in healthy adults that we read
Citrate
Not among the forms NIH names for diarrhea, but any high dose can cause it
Oxide
NIH names oxide among the forms most often reported to cause diarrhea
NIH upper limit (adults)
Glycinate (bisglycinate)
350 mg a day from supplements and medicines, whatever the form
Citrate
350 mg a day from supplements and medicines, whatever the form
Oxide
350 mg a day from supplements and medicines, whatever the form
A 2019 test of 15 commercial magnesium products found very wide differences in dissolution and absorption, so the form name alone does not decide how a given product behaves.

Common questions
What is in a bottle of pr1mebody magnesium glycinate?
A bottle holds 90 veggie capsules, which is 30 servings of three capsules, and each serving provides 360 mg of magnesium as magnesium glycinate (bisglycinate). The capsule shell is hydroxypropyl methylcellulose and the only other ingredient listed is magnesium stearate from a vegetable source.
Is 360 mg above the NIH upper limit?
Yes. 360 mg per serving is above the NIH upper limit of 350 mg a day for magnesium from supplements and medicines, and it is 96% of the 375 mg EU reference value. The NIH lists diarrhea, nausea and cramping as the effects of high intakes, so ask a doctor first if you take other magnesium or have kidney problems; if you want a lower evening dose, Tri-Mag Night provides 200 mg.
Is magnesium glycinate the same as magnesium bisglycinate?
Usually yes: both names describe magnesium bound to two glycine molecules, and PubChem lists bisglycinate as a synonym of magnesium glycinate.
When should I take it, and with what?
Take three capsules a day with a meal and a glass of water, as the label directs. The NIH fact sheet gives no time-of-day advice, and our guide on when to take magnesium explains the medicine-spacing rules.
Can I take it with other magnesium products or my medicines?
Ask a doctor or pharmacist first. The label warns about taking other products containing magnesium, and the NIH says magnesium supplements can interfere with some medicines, including bisphosphonates and antibiotics, if taken too close together.
Who should skip it or ask a doctor first?
It is for adults only, so not for under 18s. Ask a healthcare professional before use if you are pregnant, nursing, taking medication or other magnesium products, or have a medical condition, including kidney disease, because the NIH notes that the risk of magnesium toxicity rises when the kidneys clear less.
What does research say about magnesium glycinate and sleep?
We make no sleep claim for it. The research is limited and used a 250 mg dose, below the 360 mg here; our magnesium for sleep guide covers the 2025 trial and the 2026 evidence summary.
How do I compare the 360 mg with another magnesium product?
Compare elemental magnesium per serving, not capsule size or compound weight. Magnesium is about 14% of glycinate by weight, so 1,000 mg of the compound is about 141 mg of magnesium, and our types of magnesium guide has a label checklist.
How do delivery and returns work?
Shipping is free and tracked to the United States, the United Kingdom, the EU, Canada and Australia, with a tracking number within 24 hours of dispatch and estimates of 4 to 5 working days to the UK and 5 to 8 to other countries from dispatch.
