Kohnke's Own Cal-Xtra is a concentrated calcium supplement for horses grazing on oxalate pastures, as well as horses in training and growing horses. Cal-Xtra contains a concentrated source of bone minerals, calcium, phosphorus and magnesium in an optimum ratio to correct low or inadequate levels in the diet.

CAL-Xtra is especially formulated for horses consuming tropical pastures or hays where calcium uptake is reduced by oxalate compounds in the pasture and hay. Oxalate compounds bind calcium, reducing its availability, which can lead to an artificially induced calcium deficiency.
