Magnesium glycinate is a chelated mineral, supplied as a white powder and specified on elemental magnesium and the glycine carrier. The chelate is chosen for tablet and capsule formats where a milder, less alkaline magnesium source is wanted.

Magnesium glycinate is a chelated mineral, supplied as a white powder and specified on elemental magnesium and the glycine carrier. The chelate is chosen for tablet and capsule formats where a milder, less alkaline magnesium source is wanted.
This page is for buyers comparing magnesium glycinate quotations. It covers the elemental figure, the chelate identity, the tablet-size constraint and the batch tests that matter.
| Option | What it means | Best for |
|---|---|---|
| Magnesium glycinate | About 14–15% elemental magnesium; chelated | Tablets and capsules where a less alkaline source is preferred |
| Magnesium oxide | About 60% elemental magnesium; alkaline | High-dose tablets |
| Magnesium citrate | About 16% elemental magnesium; soluble | Capsules, powders and beverages |
The elemental magnesium figure is lower than magnesium oxide, so a 100 mg elemental claim needs a larger fill. That is why magnesium glycinate is often sold as a two- or three-tablet serving; the tablet weight, the excipient load and the serving size are fixed before the quotation.
The chelate is water-soluble but can be hygroscopic. In a tablet, the flow and the compression force decide the hardness; in a capsule, the bulk density decides the fill. A fine mesh blends well but can slow the press; a coarse mesh flows better but may segregate in a low-dose blend.
Magnesium is assayed by titration or ICP, and the glycine identity is confirmed. Moisture, heavy metals and microbiology are tested to the destination market's limits. The elemental magnesium figure is calculated from the assay and stated on the COA; the chelate identity is reported separately from the elemental result.
Send the elemental magnesium target, the dosage form, the tablet or capsule size, the mesh and the market. The most common mistake is to compare quotations on the chelate weight rather than elemental magnesium; the second is to choose a fine mesh for a press that already runs slowly.
How much elemental magnesium is in magnesium glycinate?
Typically about 14–15%, depending on the hydrate and the assay. Use the batch COA figure for the label; do not apply a generic conversion to a different grade.
Is magnesium glycinate water-soluble?
Yes, it is water-soluble, but it can pick up moisture. The packaging and the room humidity matter during weighing and blending.
Why is the tablet so large?
Because the elemental magnesium load is lower than oxide. A 100 mg elemental serving needs more powder, so the tablet weight or the number of tablets per serving has to increase.
Magnesium glycinate is sold here as a food ingredient. No disease or therapeutic claims are made or implied. The brand owner is responsible for the label, the elemental claim and the permitted statements in the destination market.

Shaanxi Rainwood Biotech Co., Ltd. is a botanical extract and food-ingredient manufacturer based in Xi’an, China. Since 2006 we have supplied powders, extracts and mineral salts to supplement brands and food manufacturers in North America, Europe and Asia.
For a pure powder, the things that decide whether a drum is usable are the mesh or D90, blend uniformity, moisture and the pack. That is where we focus — the powder itself, not capsule, tablet or gummy OEM. We supply 1 kg foil bags for sampling and 25 kg fibre drums for production, with a moisture barrier where the material needs it.
Every batch is released against a written specification. The COA states the method, the release limit and the batch result; the TDS, allergen statement, GMO statement and certificate copies are available before the order. Third-party testing by SGS or Eurofins can be arranged on request.
