Mechanism:Ascorbic acid maintains iron in the soluble ferrous (Fe2+) state, boosting intestinal absorption by up to 300%.

May Interfere With (Antagonisms / Blunting)
Calcium / DairyCoffee / Black TeaZinc / Magnesium

Blunting Rationale:Calcium and zinc compete for Divalent Metal Transporter-1 (DMT1); chlorogenic acid and tannins in coffee/tea chelate iron into insoluble complexes. Separate by 2 hours.
