Abstract
A composition containing a zeolite and an acid suitable for use in increasing bone strength in an animal having a bone strength less than desired and/or for use in treating, preventing or delaying the onset of a bone disorder such as osteoporosis, osteochondrosis, or dyschondroplasia. A preferred zeolite is zeolite A. Preferred acids are illustrated by citric, fumaric and aspartic acids. The presence of such acids in the composition enhances the breakdown (i.e. decomposition) of the zeolite thereby making it more efficacious for increasing bone strength or combating bone disease. Preferably, the compositions contain from about 35 to about 65 weight percent of the acid; the remainder being the zeolite Such compositions can be admixed with other materials such as excipients used in the preparation of unit dosage forms.
