Olsson’s 007 Mineral Block is a multipurpose supplement for horses grazing on all pastures and conditions. An essential mineral and trace element supplement for all race, show& working horses. The balanced levels of calcium and phosphorus in the brick build strong bones in foals, and replenishes these minerals drawn from the mare’s reserves during pregnancy and lactation. Perfect for working horses that may expel electrolytes during periods of extended activity. 007 is an economical way of maintaining mineral and trace element balance.
