We studied the influence of tea drinking on iron absorption from a controlled release iron product. The increases of serum iron level after oral administration of the product, which were measured as the index of the iron absorption, were inhibited by the combined use of tea. The inhibition was 64% in the case of the administration immediately after meal. In the case of that between meals it was lessened to 30%, however, it was enhanced to 57% by the additional use of 1g of dried aluminium hydroxide gel. From these results, the influence of tea on iron absorption was shown to be larger in the case of the administration immediately after meal than that between meals, which is assumedly caused by elevation of gastric pH value followed by the increase of iron-tannate complex formation.
