I have been using Revive 'n' Shine for approximately three months. During this time, I noticed that my horse's coat has become very silky and her dapples are more prominent. I bought this product specifically to help with mane growth and feel I ought to persevere with it as her general coat condition has definitely improved. She is less itchy and has a lovely shine. Revive 'n' Shine is very palatable and she will eat this out of my hand or in her feed. Customer service from Equinutritive is excellent. I have contacted them directly and found them to be extremely helpful and knowledgeable.
