27.6.20 - I keep seeing folk struggle with EMS ponies - how come they don't know about Metatonic as I'm blown away with the changes in my boy. If you had seem him tonight trot and canter round track cause he thought we d opened grass (lol) u'd never believe he's the same pony I've struggled with for the last few years. Need shows to restart so we can contest those veteran classes! Barbara

15.3.20 - Just wanted to let you know how well the Metatonic is working for my 22yo EMS PPID boy. His grass tolerance levels appear to have improved significantly. Long may it last! Many thanks, Alison

18.4.19 - Good morning Carol, Just wanted to let you know that I have a pony who has turned the most massive corner after introducing the advice you gave into her feed.. wow!! No more starving pony trying to eat me, no more scraping walls, kicking, biting and generally making me lose the will to live! After getting a set of X-rays done and a date with the farrier, both he and the vet asked directly if I had her sedated ... that’s what it felt like. Relaxed, happy to oblige pony. I know we have a long road ahead but without your help and advice I’d be lost!!! A million Thank Yous from me and Lotti
