SynChill Daily Pellets provide a natural, gentle way to ease anxiety and nervous in anxious horses. SynChill’s ingredients both encourage serotonin production and provide L-theanine, which helps calm the horse independent of serotonin. This two-pronged approach works in a safe and effective way to give you and your horse peace of mind during stressful events. SynChill can be used as needed, but administering daily provides a base level of supplement that maximizes its effects. It won't make your horse dull, but will help take the edge off. It can be fed as a treat or added to feed.
