Benefits
High Elemental Calcium
At about 29 percent elemental calcium by weight, DimaCal packs more calcium per gram than calcium citrate, so a given dose can be delivered in fewer or smaller pills.
Absorption Without Strong Stomach Acid
Dicalcium malate is soluble even at higher stomach pH, so it does not depend on a strongly acidic stomach the way calcium carbonate does. This makes it a practical option for older adults and people on acid-reducing medication.
Gentler on Digestion
The malate form is marketed as less likely to cause the bloating, gas, and constipation that some people experience with calcium carbonate, which can improve adherence to a daily calcium routine.
Bone Health Support
As a well-absorbed calcium source, DimaCal supplies the calcium the body uses to build and maintain bone mineral density, the central role of any calcium supplement.
Longer-Acting Calcium Delivery
Manufacturer data describe a longer absorption half-life for dicalcium malate than some other calcium salts, which may help maintain a steadier supply of calcium to the body.
Mechanism of action
Organic-Acid Chelate Solubility
Binding calcium to malic acid keeps it soluble across a range of pH values, so it dissolves and ionizes for absorption without needing a high-acid environment.
Malate as a Metabolic Carrier
Malic acid is a normal intermediate of the Krebs (citric acid) cycle, providing a biologically familiar carrier that releases calcium for uptake in the small intestine.
Calcium-Driven Bone Mineralization
Absorbed calcium is deposited as hydroxyapatite in bone and supports the calcium balance the body draws on for nerve, muscle, and clotting function.
pH-Independent Dissolution
Because dissolution does not rely on gastric acid, a larger fraction of the dose stays available for absorption in people with low stomach acid.
Clinical trials
European Food Safety Authority scientific evaluation of di-calcium malate as a calcium source (2018).
Regulatory safety and bioavailability assessment.
EFSA concluded that di-calcium malate is a suitable and bioavailable source of calcium for food supplements and foods, with no safety concerns at expected intakes.
Review comparing the absorption of calcium salts, including malate forms.
Human absorption data across calcium salts.
Organic-acid calcium salts such as malate forms were absorbed well relative to calcium carbonate, supporting the bioavailability rationale for dicalcium malate.
