Lumbrex is one of the most-requested formulas in the Gold Standard Herbs line — currently featured in Dr. Judy Morgan's "Senior Essentials" collection and frequently backordered. The herbs are designed to support circulation to the spine and hindquarters, ease lumbar stiffness, and help senior dogs move more comfortably day to day.
