You've been watching it happen. The hesitation at the stairs. The dull coat. The spark that fades by the week.
"Wish I would have started sooner." — It's the most-repeated five-word phrase across thousands of senior-dog supplement reviews. Don't be the one who says it next.
- He pauses at the bottom of the stairs at 7 AM, one foot in the air, looking up.
- The coat you used to call "silk" now feels rough. The shedding won't stop.
- He doesn't jump on the couch anymore — the couch you've shared for eight years.
- The vet says "this is just normal aging" and hands you a $60 bag of prescription kibble.
- You scroll Facebook at 11 PM, see another senior-dog post, and cry without knowing why.
Aging hits your dog in two places at once. Every other supplement fixes one.
Dasuquin fixes joints — but ignores his cells. Leap Years fixes cells — but ignores his coat. PawVital is the first drop that does both.
Cellular: liquid NMN restores NAD+
NAD+ powers every repair system in your dog's body. From age 5–10, his cells lose 50–70% of the NAD+ they need to function. Mitochondria fail. Inflammation builds. Energy crashes. Our sublingual liquid NMN bypasses stomach acid — so the molecule actually reaches the cell.
6-ingredient cellular stack · Energy, stairs, focus · Visible by week 4Structural: hydrolyzed collagen + HA
Collagen production slows roughly 1–1.5% per year after age 5. Joints lose cushion. The coat goes dull. Types I, II & III collagen peptides plus hyaluronic acid in liquid form rebuild the structural protein his glucosamine can't touch.
6-ingredient structural stack · Coat, joints, mobility · Visible by week 2Two visible proof windows. One squeeze a day.
Week 2: his coat changes. Week 4: his stairs change.
Start the 21-Day Reset →Two complete stacks. One drop a day.
Aging doesn't happen in one system — it happens in his cells and his connective tissue at the same time. Every other senior-dog supplement picks a lane. PawVital runs both.
The Cellular Stack
for the energy, focus, and spark that fade from the inside
- Liquid NMN50mg
NAD+ precursor in sublingual liquid form. Bypasses the up-to-85% loss capsule NMN takes in the stomach.
- NAD+
Added directly alongside the precursor for daily cellular fuel.
- Resveratrol
The sirtuin activator NMN was made to pair with.
- CoQ10
Mitochondrial cofactor.
- Quercetin
Senolytic flavonoid. Helps clear senescent cells aging leaves behind.
- Astaxanthin · Vitamin C · Vitamin E
The antioxidant ring protecting what the rest of the stack rebuilds.
The Structural Stack
for the coat, the joints, and the stairs he's stopped climbing
- Hydrolyzed Collagen I & III1,500mg
Peptide form. The skin, coat, and connective-tissue protein. Liquid delivery dogs can't spit out.
- UC-II (Undenatured Type II Collagen)40mg
The form clinically studied in dogs with osteoarthritis. Four times the dose used in the published Gupta 2012 trial.
- Hyaluronic Acid
Joint synovial cushion. Skin moisture matrix.
- MSM
Sulfur donor. The raw material connective tissue needs to rebuild.
- Omega-3 DHA/EPA
Anti-inflammatory backbone. Coat shine you can see in two weeks.
- Biotin
Coat and skin finishing cofactor.
Every batch third-party lab tested. Certificates of Analysis published openly. Full Supplement Facts panel on every bottle.
The transformation, week by week.
You'll see the coat first. The stairs second. By month three, you'll forget what the old version of him looked like.
Slower mornings, dull coat, fading spark
He hesitates on the stairs. The coat feels rough. He naps more, plays less. You catch yourself watching him too closely.
The coat shifts first
Softer to the touch. Less shedding. The collagen is reaching the follicles. Your hand on his back feels like the dog you remember.
The mornings get easier
He gets up faster. Hesitates less. The walk doesn't end early. NAD+ is reactivating the cellular machinery his joints depend on.
The spark you'd given up on
He's at the door before you grab the leash. He climbs the couch like he used to. You catch yourself smiling for the first time in months.
The only complete formula for senior-dog aging.
Every other brand gives your dog half the formula. Some get the science right and the format wrong. Some get the format right and skip the science.

Four things every dog parent gets told. None of them are quite true.
*Timeframe drawn from peer-reviewed canine OA collagen-peptide trials (D'Altilio 2007, Gupta 2012). Individual results vary with breed, age, weight, and consistency of daily use.
The four signs you'll catch first.
Most pet parents call out one of these before week three. Then they see the next.
Softer, shinier coat
Less straw-like brittleness. Less hair on the couch.
Easier mornings
Faster to get up. Less hesitation on the first few steps.
The spark is back
Tail wagging harder. Wanting the walk again. Greeting at the door.
Faster recovery
Less stiffness after a long walk. Bouncing back the next day.
Why pet parents say it better than we could.
Reviews quoted from independent Chewy, Amazon & Petco verified-purchase customers in the senior-dog supplement category.
Formulated and endorsed by practicing DVMs — not a marketing team.
Every ingredient, every dose, every batch is signed off by veterinary professionals with verifiable credentials. We publish their names because we'd rather you be able to look them up than take our word for it.
"[PLACEHOLDER QUOTE — 2–3 sentences in the DVM's voice explaining why they built the formula this way. Reference the two-front mechanism: cellular NAD+ decline plus structural collagen loss. End with the format rationale — why liquid over capsules or chews.]
"[PLACEHOLDER QUOTE — 2–3 sentences from an independently practicing DVM endorsing the formula. Reference the absorption advantage of liquid sublingual delivery, the quality of the ingredient sourcing, or the lack of a credible combined NAD+/collagen product on the market until now.]
