Calcium chelates

Oxalates

Bind calcium into an insoluble salt. Relevant for calcium uptake and for anyone who forms calcium-oxalate stones.

Phytic Acid

The storage form of phosphorus in seeds, grains and legumes. Grips divalent minerals in the gut so they cannot be absorbed.

Calcium competes for transporter with

Non-Heme Iron

Iron from plants and fortified foods. Absorbed through DMT1 in the ferrous state, so it is the form vitamin C rescues and the form phytate, tannins and calcium block.

Zinc

Structural and catalytic cofactor in hundreds of enzymes, including steroidogenic ones. Shares absorption machinery with iron and copper.

Calcium enhances absorption of

Vitamin D

Acts as a hormone rather than a classical vitamin. Governs calcium absorption and a wide set of immune genes.
