Abstract: A fortified salt mixture includes sodium chloride salt grains and a multi-supplement food-additive admixed with the sodium chloride salt grains. The multi-supplement food additive includes particles, and each particle includes a core having a first supplement and a binder, a coating on the core, and a second supplement in the core and/or in the coating. A method for fortifying salt ncludes combining a first supplement, a second supplement, a binder and a coating to yield a multi-supplement food-additive; and admixing the multi-supplement food-additive with sodium chloride salt grains.
