The Silver Lining Herbs Brain & Nerve Support Horse Supplement supports central nervous system health in your horse for normal and healthy brain activity. Factors like attention, focus and even gait patterns originate in the central nervous system, and this supplement may help to stabilize attitude and performance in your horse. It’s well-suited for horses who have short attention spans or difficulty focusing, and premium herbs also offer secondary support to your horse’s digestive and immune systems. With improved focus, you and your horse may enjoy more enjoyable and productive training sessions.
