Who should buy which
Owners of adult or senior dogs who want the most research-backed pet-longevity supplement available and are comfortable with a premium monthly subscription.
You have a puppy, you want proven lifespan extension rather than early-stage cellular-health support, or a $30 to $117 monthly cost is more than the experiment is worth to you.
Owners of senior or aging dogs who already believe in NAD+ support for themselves and want the most direct, single-active way to extend that thesis to their dog.
You want proven, vet-backed outcomes today, or you would rather spend on a broad senior multivitamin that covers joints, gut, and heart in one chew.
