Our Guiding Principles
Three rules we don't break.
Every dose, printed
Plenty of senior dog drops don't say how much of each ingredient is inside. We print every milligram on the bottle and on this page.
Essentials only
Four active ingredients, each with a clear job. No xylitol, no pills, no chews left on the floor.
Honest about the research
We tell you what studies show, and where the evidence in dogs is still early. No "clinically proven", no "adds years".
Ingredients Directory
What's in every 1 ml dropper, and why it's there. Tap an ingredient to learn more.
NMN (nicotinamide mononucleotide)30 mg
A building block the body uses to make its own NAD+, the molecule cells use to turn food into energy. NAD+ levels fall with age in studies of people and animals. An ideal NMN dose for dogs hasn't been set, which is why we dose by weight and print exactly what's inside.
NAD+ (nicotinamide adenine dinucleotide)100 mg
The energy-helper molecule itself. Research on how well NAD+ taken by mouth is absorbed is limited, so the formula pairs it with NMN, the building block.
Resveratrol5 mg
An antioxidant found in grapes and berries, often paired with NAD+ building blocks. Research in dogs is limited.
Coenzyme Q10 (CoQ10)5 mg
An antioxidant cells use in energy production. Research in healthy senior dogs is limited.
Other ingredients: vegetable glycerin, purified water, rice syrup, beef and apple flavouring. No xylitol.
Our Process
From the research to your dog's dinner bowl.
Formulated from the research
Ingredients chosen from published research on NAD+ and healthy aging, dosed by your dog's weight, and paired with a free 2-Minute Senior Dog Routine, because regular gentle exercise is the best-supported way to help senior dogs keep their muscle.
How it's made
