Magnesium Glycinate Capsules, 275 mg Elemental
EO VITA Magnesium Glycinate: 275 mg elemental magnesium per serving (three capsules), 30 servings, $0.83 per serving. Single ingredient, third-party tested. For adults who want a daily magnesium supplement with the elemental dose stated up front.
Which form of magnesium should I take?
It depends what you are comparing. First, compare elemental magnesium, not compound weight: that is the number that tells you how much magnesium you actually get. Glycinate is a good everyday default because it dissolves well and tends to sit easily. Citrate also absorbs well and costs less, but can loosen stools. Oxide carries the most magnesium per pill, but less of it is absorbed. Whatever you choose, keep supplemental magnesium at or under 350 mg a day. If you want something easy to take every day, choose glycinate.
Elemental magnesium is the number that matters
A magnesium glycinate compound weighs far more than the mineral it carries, because the weight includes the glycine bound to it. A front label showing only the compound weight makes a product look stronger than it is.
So here it is in the form you can use: 275 mg of elemental magnesium per serving, from 2,500 mg of magnesium glycinate. The 275 mg is what you weigh against the Daily Value and against anything a clinician has told you.
An essential mineral, and the sleep claim it cannot make
Magnesium is a cofactor in more than 300 enzyme systems, which is why it matters as a daily mineral. The evidence does not support selling it as a sleep treatment, and we do not.
| Study | Population | n | Dose | Length | Primary outcome |
|---|---|---|---|---|---|
| Sleep RCT Randomized, adults over 51 |
Poor sleep quality | — | 320 mg | 7 weeks | Sleep scores improved in both groups. Magnesium did not outperform placebo on the overall outcome. |
| Insomnia RCT Double-blind, older adults |
Primary insomnia | — | 500 mg | 8 weeks | Some sleep measures improved in a small trial. The overall insomnia evidence remains limited. |
| NIH ODS review Office of Dietary Supplements |
Review | — | — | — | Soluble magnesium forms are absorbed more completely than less soluble ones such as oxide. Not a basis for a superior-absorption claim. |
In a randomized trial of adults over 51 with poor sleep, magnesium did not outperform placebo on the overall outcome. Take it in the evening if that suits your routine, but it is not a sedative.
Soluble chelated forms tend to absorb more completely than oxide, which is a real point in its favor. It is not a basis for claiming superior bioavailability or no laxative effect, so we do not.
How we evaluate evidenceThree capsules a day, whenever suits you
Three capsules once daily with water, providing 275 mg elemental magnesium.
Evening is fine if that fits your routine. It is not a sedative.
Count magnesium from all your supplements and antacids toward your total.
The adult Tolerable Upper Intake Level for supplemental magnesium is 350 mg a day, not counting food. High intakes can cause diarrhea and cramping, and risk rises with impaired kidney function. Magnesium can interfere with certain antibiotics and bisphosphonates. Talk to a clinician if you have kidney disease, take medication, are pregnant, nursing, or under 18.
One mineral, labelled honestly
The elemental amount comes first, because that is the number you can compare.
Made in a facility certified to current Good Manufacturing Practice, and the manufacturer completes third-party testing on the material. What we cannot do yet is hand you the certificate. Those documents belong to the manufacturer and are not released for marketing use, so we are not going to publish one or imply that we have. As individual products earn the volume, we are moving them to our own batch runs, which puts lot-level testing under our control and makes published results possible. When that happens for this product, it will be said here.
What it supports
These are the normal roles of an essential mineral. They do not mean a supplement resolves every symptom the internet files under low magnesium, and we do not claim that.
Magnesium participates in nerve signaling, muscle contraction and ion transport. These are normal physiological roles, and they are why magnesium is worth taking consistently.
Magnesium is required in the reactions behind energy production and oxidative phosphorylation. That is its biochemical role, stated as such.
Magnesium contributes to bone structure and normal protein synthesis. It is an essential mineral doing essential-mineral things.
Answers

Why does the label look like less magnesium than other brands?+
Because we lead with elemental magnesium, 275 mg, not the 2,500 mg compound weight. A brand showing the compound weight looks stronger than it is.
Is glycinate better absorbed?+
Soluble chelated forms tend to absorb more completely than oxide, which is a fair reason to choose it. Direct proof that glycinate beats every other form is limited, so we do not claim it.
Will it help me sleep?+
We do not sell it as a sleep aid. In a randomized trial it did not beat placebo on the overall sleep outcome. Take it in the evening if you like; it is not a sedative.
Can I take too much?+
The upper level for supplemental magnesium is 350 mg a day. This provides 275 mg, so a second source can put you over. Count everything and ask a pharmacist about spacing with medication.
How do I pause or cancel a subscription?+
From your account, in one click, before the next order is charged. No email and no retention call.
What people who finished a bottle said
Every review here comes from a verified order. We do not write them, we do not buy them, and we do not remove the unflattering ones.
We publish every review from a verified purchase. We remove only spam, abuse, off-topic posts, and claims that a supplement treats or prevents a disease, which we are not permitted to publish. Those rules apply to five star reviews exactly as they apply to one star reviews.
The EO VITA promise
EO VITA builds products around the best available research. Everything we sell is made in a GMP certified facility, and the manufacturer completes third-party testing on the material. If you are not satisfied with what you receive, tell us and we will make it right.
Third-party tested material
Every product is made in a GMP certified facility, and the manufacturer completes third-party testing on the material. We are not able to publish those certificates yet, and we say so on the page rather than implying otherwise.
Science-based
Everything we sell is grounded in peer-reviewed human research, and we tell you who funded each trial. Where the evidence is thin or negative, we say so rather than filling the gap with a louder claim.
We take it too
Every product we make is used regularly by the team at EO VITA. If we do not take it ourselves, we do not sell it to you.
Where it sits in the range
Magnesium is the foundational mineral in the lineup, a cofactor the energy-producing reactions cannot run without. It is not a mitochondrial-quality product like Urolithin A. It is the daily baseline the rest sits on top of.
Three things worth knowing before you buy any magnesium
Read the elemental number
A magnesium compound weighs far more than the mineral inside it. Compare products by elemental magnesium, which here is 275 mg, not the 2,500 mg compound weight.
Glycinate, honestly
Soluble chelated forms absorb better than oxide, a real advantage. That is not the same as proof it beats every form or that it never loosens stools, so we do not claim either.
Not a sleep treatment
Magnesium is involved in nerve and muscle function, but the sleep trials do not support selling it as a treatment. Take it in the evening if you like; it is not a sedative.
