Biotal Equine Gold has been specifically selected from a thousand different strains of yeast for its beneficial effect on 'friendly bacteria' in the gut. Because it contains a pure live yeast, it provides a much more concentrated source of 'live' yeast cells. Specifically, Equine Gold stimulates the production of bacteria capable of utilising lactic acid and so keeps acidity levels in check. It also competes with less favourable bacteria for the available food source, therefore keeping their levels controlled. The positive effect that Equine Gold has on the hindgut environment is beneficial to all horses and ponies, and when fed daily, it helps maintain a healthy balance of microflora within the digestive tract by supporting 'friendly bacteria' and in doing so, stabilises digestion, combats stress and strengthens the immune system.
