  • ABOUT GOOD DAYS
  • PRODUCT & INGREDIENTS

Good Days combines two formulas that support the key pillars of aging well: mind, gut, immunity, and mobility. Old Pals supports brain, immune, and gut health while Good Stretch supports joint, spine, and nerve function. When all these systems get consistent daily support, dogs show real improvements in overall quality of life.

Good Days is designed for senior dogs (7+ years). It's ideal if you're currently juggling multiple supplements, want to simplify your routine, or want proactive support that addresses aging holistically. This bundle replaces 8-10 separate bottles with two scoops.

Good Days is formulated with senior dogs in mind, but it's safe for adult dogs too. Puppies under 12 months or dogs should only use it under the guidance of a veterinarian to ensure it meets their developmental needs.

Good Days addresses the root systems that affect senior wellness: mobility, digestion, cognition, and immune function. Rather than masking symptoms, we support natural processes. Every dog is unique, which is why we offer a 90-day guarantee. If you don't see improvements in movement, digestion, and overall vitality, we refund every dollar.

You’ll usually notice digestion improvements first - sometimes within a week. Structural improvements such as those in joint and mobility can take longer, building steadily over 2–3 months of consistent use. We're supporting natural processes, not masking symptoms, so sustainable improvements take time.

Most chews are built like treats - 70–80% fillers to hold their shape. Powders skip the junk, keep full potency, and let you adjust dosing easily. No heat to degrade nutrients, no binders, just active ingredients you can mix into food or broth. Got a picky eater? Reach us at support@kinsupersupps.com and we’ll send you our feeding guide.

Yes. You can mix both scoops together and give them at the same time. It’s the easiest way to keep their feeding routine simple, and the formulas are designed to complement each other.

Just one: flaxseed. It keeps the powder smooth without synthetic flow agents like silicon dioxide or magnesium stearate. Flaxseed also brings omega-3s and fiber for digestion, skin, and coat.

All of our ingredients come from vetted suppliers who meet NASC requirements for quality and traceability. Our mushrooms are USDA-organic fruiting bodies, our probiotics are individual strains, not a blend, sourced from cGMP-certified facilities, and our KSM-66® Ashwagandha is the patented, clinically-studied form. Every ingredient includes safety and purity testing before they’re used.

Both Old Pals and Good Stretch are manufactured in the United States at an FDA-registered, cGMP-certified facility specializing in nutritional supplements. The facility is also NASC-certified, meeting the highest standards for pet supplement manufacturing.
