Magnesium Guide: Forms, Labels, Serving Sizes & 90-Day Supply
Updated October 26, 2026 · Alurevia Editorial Team
This guide brings Alurevia’s magnesium education into one place: how to read elemental magnesium, what the common magnesium forms are, how single-form products differ from magnesium complexes, how serving size changes bottle duration, and how to compare products on cost per day.
If you are comparing magnesium supplements, the most useful starting points are elemental magnesium per serving, serving size, the forms listed, capsule count and product directions, not a single phrase on the front of the bottle.
Start here: reading a magnesium label
- What Is Elemental Magnesium? How to Read a Supplement Label: why a 500mg compound and 500mg of magnesium are not the same thing.

- How Long Does a 90-Capsule Magnesium Bottle Last?: capsules per bottle divided by capsules per day.
Magnesium forms, compared
A magnesium form tells you what magnesium is chemically paired with. Compounds differ in elemental magnesium density, solubility and absorption. The form name alone does not prove that one finished supplement is better than another.

Where Alurevia Magnesium Complex fits
Alurevia Magnesium Complex provides 500mg elemental magnesium in one veggie capsule from eight named sources: oxide, glycinate, malate, taurate, citrate, carbonate, aspartate and orotate. Magnesium oxide is listed first and is the primary source. Each bottle contains 90 capsules, a 90-day supply at one capsule a day: $35 one-time, or $31.50 every 3 months with Subscribe & Save.
Safety
The Food and Nutrition Board sets a tolerable upper intake level of 350mg per day for magnesium from supplements for adults, separate from magnesium naturally present in food. Alurevia Magnesium Complex provides 500mg elemental magnesium per capsule, which is above that supplemental upper limit.
Follow the product directions and speak with a healthcare professional before use, particularly if you have kidney disease, take prescription medicines, are pregnant or nursing, or use other supplements containing magnesium.
