NR (Nicotinamide Riboside) — converts to NAD+ rapidly, giving depleted cardiac cells an immediate energy supply.

NMN (Nicotinamide Mononucleotide) — sustains NAD+ production over time so levels don't drop the moment the supplement wears off.

Niacinamide — the foundational precursor that supports the base conversion pathway both NR and NMN depend on.

CoQ10 — supports the mitochondria inside cardiac muscle cells that convert NAD+ into usable energy for every heartbeat.

Resveratrol — protects heart cells from the oxidative damage that accelerates during NAD+ depletion.

Hear From Our Customers

  • A few months ago, our 12-year-old just wasn't the same dog. He tired easily and spent most of his day resting. After adding these drops to his daily routine, we've noticed a real difference in his energy and overall spirit. He's excited for walks again and even greets visitors at the door.

    Susan Mitchell

  • After my dog's murmur was diagnosed, I was in pieces. Started this on my vet's advice. Within 3 weeks his energy was completely transformed. Back to stealing socks and demanding walks. Latest check-up showed his heart sounds notably stronger.

    Michael Bennett

  • I have seen a BIG difference at about the 2 week mark. The coughing at night stopped and he's actually moving around the house again. Ordered 4 more bottles.

    Your Pup's Journey With Happy Paws

    1. check_circle

      WEEK 2-4

      The exhaustion after small movements starts to ease. They're more willing to get up. Breathing feels slightly less labored. They start having more alert moments in the day.

    2. check_circle

      WEEK 4-8

      They're moving through the house more. Less coughing at night. Eating with more appetite. The dog that was slipping away starts showing you the one you know.

    3. check_circle

      WEEK 8-12

      This is where dog parents say "I got more time than the vet gave us." Not cured. Not a miracle. But present, comfortable, and still themselves — and that's everything.

    FAQs

    NAD+ is the molecule your dog's heart cells run on. As dogs age — and especially as heart disease progresses — NAD+ levels in the cardiac muscle can become critically depleted. The heart is beating on empty.

    This formula uses Triple Precursor Technology — NR, NMN, and niacinamide — to support NAD+ levels through convergent biosynthesis pathways. CoQ10 addresses the downstream side of mitochondrial energy transfer. Two adjacent links in one formula.

    Most dog parents notice the first shifts around week 2 — typically more willingness to move and slightly less labored breathing. The meaningful changes develop between weeks 6 and 12.

    Earlier intervention generally works better, but later-stage dogs still respond.

    The mechanism — supporting NAD+ in cardiac cells — is relevant regardless of how long the depletion has been happening. You may see slower progress, but the formula addresses the same cellular energy challenge at the root of the decline.

    NAD+ is a naturally occurring molecule. It works alongside your dog's current protocol — not by interacting with medications directly, but by addressing what medications were never designed to touch: the cellular energy supply inside the heart muscle.

    As always, check with your vet before adding anything new to your dog's regimen.

    Give your dog 90 days. If you don't see more good days than bad, contact us and we will help you out. One email, full refund. No bottles to return, no explanations required.
