Antonia Platt is a showjumper based in Surrey. She has been riding since she can remember. Now 21, she competes regularly against adults on the international circuit with her horses Marvin van de Waterhoeve, Amigo and Patton M. Her recent successes include winning the Under 25 championships at the Royal Windsor Horse Show in May, taking fifth place at the Great Yorkshire Show, the biggest national competition in Great Britain, and fourth place in the Grand Prix of the London leg of the Global Champions Tour.

She has also started competing on three young horses, two of whom are homebred. She is currently studying agriculture at the University of Nottingham.

“All my horses are fed on Coligone. I use the Coligone Liquid alongside the powder supplement and I have seen great changes in the digestive health of my horses including improved appetite and condition. Another benefit is that they seem to be calmer and more relaxed; for one horse in particular Coligone has been transformative.”
