I'm not really one for loads of supplements as I try to keep my horse in a natural way, designed for her needs. However, she came to me with issues which we've been working on together with some reiki and some professional help. Someone on my yard suggested no more nerves and I thought it might suit my girl as she is very reactive and if pressed will become dangerous and it's no fun at all. It works really well!! Just takes the edge off her behaviour so we can work on our training and she can learn that just because I ask her to walk on, the whole world isn't out to get her. Still full of character and fun and I'm glad that hasn't changed, but has really helped us break through in her feeling safe and calm enough to let me lead. The lady who recommended it said the dame, it just took the edge off her show arab so everyone could enjoy themselves more with less stress. Thanks for a great product.
