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

Calcium
Bone mineral and signalling ion. A large calcium load in the same meal competes with non-heme iron for DMT1.
Magnesium
Required by every ATP-dependent reaction, since the usable substrate is the Mg-ATP complex rather than ATP alone.
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.
