They also coordinate the research behind the SmartPak-brand supplements and provide customers with educational information. Dr. Appleton focuses on new product concepts and novel ingredients, development batches and label creation. Dr. Gray’s time is spent on the palatability studies that occur before any SmartPak-brand supplement is launched, as well as scientific research studies documenting an ingredient or a product’s safe use in horses, its bioavailability, and other testing.
