A coated ferric pyrophosphate composition in which ferric pyrophosphate is coated with, per 100 parts by mass of the ferric pyrophosphate, 1 to 10 parts by mass of a polyoxyethylene sorbitan fatty acid ester or 1 to 10 parts by mass of a glycerin fatty acid ester and 0.05 to 1 part by mass of enzymatically decomposed lecithin and which has a zeta potential of -25 to -39 mV and an average particle diameter of 1 to 4 mm； and an iron-enriched fermented milk which contains 1.0 to 10 mg, in terms of iron originating from ferric pyrophosphate, of the coated ferric pyrophosphate composition per 100 g of a fermented milk having an absolute zeta potential value of 10 mV or smaller. The coated ferric pyrophosphate composition according to the present invention is usable in fermented milks such as yogurts, yogurt beverages, lactobacillus beverages, etc.
