Grass, in rapid growth mode, or stressed by over-grazing or the weather, becomes minerally imbalanced. This causes mineral imbalances in the horse. Whilst nature has provided the horse with efficient self-regulating mechanisms to keep the body functioning normally at these times, many horses eventually become overwhelmed resulting in the various health and behaviour issues. Graze Ezy has been formulated to help neutralise or 'buffer' these imbalances in the grass. It is important to start with 10gms per feed and gradually increase the dose. If the manure softens then just revert to the previous amount.
