Magnesium citrate is magnesium bound to citric acid, forming one of the most bioavailable and widely used magnesium supplements. It's commonly taken for general magnesium supplementation, muscle relaxation, and digestive regularity — citrate has a mild osmotic laxative effect at higher doses. Labels typically show two numbers: the elemental magnesium content (what your body absorbs) and the total compound weight (which includes the citric acid). For example, a product listing "Magnesium (as Magnesium Citrate) 150 mg" provides 150mg of elemental magnesium from a larger amount of the citrate compound. This page compares products by the elemental magnesium content — the number that matters for your daily intake. Products below are ranked by cost at your chosen daily dose.
Read our Magnesium Citrate price comparison article for tips on what to look for when buying magnesium citrate.

This is the current ranking surface for Magnesium Citrate. It recalculates cost per month from product price, Supplement Facts active amount, servings per container, and the dose you enter above.
76 active products have enough price and label data to calculate cost before display filters; 73 rows are currently shown in the ranked table. The current review floor for this category is 25+ reviews before any large-category and duplicate/bulk filtering.
At 400 mg/day, visible products range from $1.34-$26.50/mo with a $6.82/mo median midpoint and a 19.8x low-to-high spread.
Use the elemental magnesium amount from lines like "Magnesium (as magnesium citrate)", not the total magnesium citrate compound weight. Labels reviewed for this update included capsules, tablets, powders, liquids, and gummies with elemental magnesium listed separately.
Cost depends on elemental magnesium per serving, format, serving count, and whether the product is a plain citrate or a multi-magnesium blend. Gummies and liquids often cost more than tablets or powders at the same elemental target.
Do not compare magnesium citrate compound weight to elemental magnesium. Also watch for blends where citrate is only one of several magnesium forms, because those belong in the citrate comparison only when the label supports a clear citrate amount.
Magnesium citrate has strong evidence context as a widely used magnesium form with good bioavailability. TrueServing compares labeled elemental magnesium cost at 400 mg/day and does not rank laxative, sleep, or muscle claims separately.
