Herd Sports Chew was designed and formulated on the basis of what is currently known in the literature about the potential benefits of certain supplements. From this starting point, key ingredients were selected and formulated into a premium chew. Assorted peer-reviewed medical and scientific literature supporting the design of Herd Sports Chew are listed below with links to their associated abstracts:
