The readily absorbable calcium compositions of the conventional art have a problem. They immediately settle out when added to beverage and the like due to their large particle diameter. Another problem is that the wet grinding step, which intends to reduce the particle diameter, requires time and cost. A calcium salt is produced by dripping a carboxylic acid aqueous solution onto a hydrated lime slurry while it is being stirred and spray-dried into granules. In this way, calcium salt primary particles can have a small size and calcium salt can be prevented from precipitating.
