Silicon Silica

Non-metallic element and the most abundant in the earth’s crust. Whilst no requirement level has been established for horses it is speculated that Silicon may be important for bone and cartilage formation and possibly connective tissue strength. Sources include natural volcanic clay minerals (Zeolites) some of which provide silicon in a bioavailable form. A study of young racehorses which received Zeolite supplements during their growth phase indicated longer racing careers, more starts and fewer breakdowns due to soft tissue injury (tendons & ligaments) that un-supplemented controls. Further research to establish requirement levels and effect on bone & cartilage is needed.
