Two months in, your dog’s body has been running on elevated NAD+ levels for weeks—and that consistency matters. Every day, billions of their cells renew themselves, from skin and gut to heart and muscle. With more NAD+ in circulation, these renewal processes work more efficiently, supporting healthier tissues, smoother skin, and steadier digestion. Inside, their cells are better equipped to clear out waste, repair damage, and keep vital organs like the liver functioning at their best. What you might notice on the outside: a glossier coat, more balanced energy, and a dog that simply feels better in their own skin.
