In various implementations, an oxalate absorption blocking (OAB) composition may be administered to improve a health of an individual. The OAB composition may include calcium and/or magnesium. In some implementations, the OAB composition may include one or more carbonates, probiotics, vitamins and/or other minerals. A therapeutically effective amount of the OAB composition may be administered to reduce oxalate absorption from foods consumed by an individual. Reducing oxalate absorption from foods consumed by an individual may decrease pain, improve movement of joints, inhibit kidney stone formation, and/or otherwise improve an individual's health.
