Calm & Collected Gold is a liquid supplement with herbs such as chamomile and valerian which helps maintain a healthy nervous system in horses of all ages. After the first use, you can move onto the dry equivalent, Calm & Collected (we do not recommend giving both together). If you notice your horse becoming tense or nervous, try to find out what could be causing this.If your horse is on box rest due to an injury, the Rest & Recover Gold might be more suitable. For mares that are affected by their seasons, consider Easy Mare Collection.
