In one of its aspects, the present invention provides a composition comprising: (i) a non-encapsulated iron salt, and (ii) a carrier comprising digestible edible oil that is a liquid at 20° C. This composition advantageously provides iron in a form that is easily administered to an infant or adult. When taken directly by mouth or added to food or infant formula, the composition has a desirably bland flavor and is easy to consume. Moreover, the high density of iron per unit volume of the composition results in a minimal volume of liquid to be administered. This makes the composition relatively innocuous and easy for infants to consume. Related aspects of the present invention are also described&mdashe.g., uses, articles of manufacture and the like.
