How MarrovaPets Renew Protocol Works
Everything you need to know about giving your dog MarrovaPets Renew Protocol — what to do, how much, and what to watch for.
Pour the dose
Squeeze the dropper to the line for your dog's size. Tasteless. Odorless. He won't even know it's there.
Drop on his food
Mix into wet or dry food once a day, with a meal. No pill wraps. No peanut butter trick. No fight.
Watch over 21 days
Coat shifts first (week 2). Mornings get easier (week 4). The spark returns (week 8). The transformation unfolds.
Giving Your Dog The Proper Dosage
Match the dropper amount to your dog's weight.
For best results, give your dog the proper dosage with food — this provides optimal absorption. Cellular repair takes 60–90 days to reach full effect, which is why we recommend a 3-bottle reset minimum.

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 supports one.
Tap a tab to see how MarrovaPets supports both fronts in one tasteless daily drop.
Two complete complexes. One daily dropper.
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. MarrovaPets runs both.
Longevity & Cellular Complex
for the energy, focus, and spark that fade from the inside
- NAD+ (Nicotinamide Adenine Dinucleotide)33 mg
Daily cellular fuel. The molecule his mitochondria stop making enough of after age 5.
- NMN (Beta-Nicotinamide Mononucleotide)17 mg
NAD+ precursor delivered sublingually. Bypasses the up-to-85% loss capsule NMN takes in the stomach.
- CoQ10 (Ubiquinol)13 mg
Active, absorption-ready form. Mitochondrial cofactor for energy production.
- Trans-Resveratrol7 mg
Sirtuin activator. The molecule NMN was made to pair with.
Skin & Barrier Complex
for the coat, the joints, and the stairs he's stopped climbing
- Hydrolyzed Collagen Peptides (Type I & III)267 mg
Peptide form. The skin, coat, and connective-tissue protein.
- UC-II® Undenatured Type II Collagen13 mg
Clinically studied form for canine joint comfort. Works via oral tolerance.
- MSM (Methylsulfonylmethane)133 mg
Sulfur donor. The raw material connective tissue needs to rebuild.
- Omega-3 (DHA + EPA, Algal Oil)133 mg
Plant-derived omega-3s. Anti-inflammatory backbone. Coat shine in two weeks.
- Quercetin (Phytosome)33 mg
Senolytic flavonoid in bioavailable phytosome form.
- Hyaluronic Acid27 mg
Joint synovial cushion. Skin moisture matrix.
- Vitamin C (Sodium Ascorbate)33 mg
Collagen synthesis cofactor. Buffered form.
- Astaxanthin (Algae-Derived)2.7 mg
The strongest natural antioxidant for joints and coat pigment.
- Vitamin E (Mixed Tocopherols)10 IU
Lipid-soluble antioxidant ring.
- Biotin200 mcg
Coat and skin finishing cofactor.
Doses shown per 1 mL (1 dropper). Medium dogs receive 3 mL daily. Every batch third-party lab tested. Certificates of Analysis published openly.
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.
