- 🐶 Adult and senior dogs
- 💧 Liquid, once a day
- ⚖️ Dose by weight
Your dog is getting older. Walks are shorter, naps are longer, and you want their later years to be as good as they can be, as long as anything you add is safe. You have seen NMN and CoQ10 drops for dogs and want to know what is actually in them and whether they make sense for your dog.
The Petstone Daily Liquid Supplement for Dogs is a once-a-day liquid with NMN, CoQ10 and resveratrol that you add to food, dosed by your dog's weight. It is meant to help support everyday energy and healthy aging in adult and senior dogs, and it is best started after a conversation with your vet. This guide covers what is in it, how to dose it, who should check first, and what the research does and does not show.
Quick answer
- It is a once-daily liquid added to food, in a 2 fl oz (60 mL) bottle.
- Listed ingredients: NMN and NAD+, CoQ10 and resveratrol, with nanoliposomal delivery.
- Dose by weight, from half a dropper (under 22 lbs) to 2 droppers (over 88 lbs).
- Ask your vet first if your dog has a health condition, takes medication, or is pregnant or nursing.
- Research on NMN in dogs is limited; it is a dietary supplement, not a medicine.
What is in the Daily Liquid Supplement for Dogs
All product facts here come from the Daily Liquid Supplement for Dogs product page. Petstone sells it as its own product, so there is no separate brand site.

| NMN and NAD+ | Listed to help support cellular energy and normal metabolic function |
| CoQ10 | Listed to help support cellular energy production, with antioxidant support |

The page does not list the amount of each ingredient per serving, the dropper volume, servings per bottle, flavor or storage. If those details matter for your dog, ask Petstone support (Monday to Friday, 9 to 5 EST) or your vet before you start.
It is sold in three pack sizes:
- 📦 1 bottle
- 📦 3 bottles
- 📦 6 bottles
How much to give: dosing by weight
The product page gives one weight-based serving per day, added to food.
| Your dog's weight | Daily serving |
|---|---|
| Under 22 lbs | Half a dropper |
| 22 to 55 lbs | 1 dropper |
| 55 to 88 lbs | 1.5 droppers |
| Over 88 lbs | 2 droppers |
- Talk to your vet first, and bring the bottle or the product page with you.
- Weigh your dog so you use the right row in the table.
- Add the serving to one meal a day, at the same meal each day.
- Keep a simple note of appetite, energy and stools for the first few weeks.
- Stop and call your vet if you notice anything unusual.
Who it suits, and who should check with a vet first
✅ A good fit for
- Adult and senior dogs whose vet is happy for them to take a daily supplement
- Owners who prefer a liquid over tablets or powders
- Dogs who eat a meal reliably, so the dose goes in
⚠️ Check with your vet first
- Dogs with a medical condition or on any medication
- Pregnant or nursing dogs
- Dogs with new or unexplained tiredness, which needs a checkup, not a supplement
Supplements can interact with medications, as Tufts Petfoodology points out. If your dog's energy has dropped suddenly, or tiredness is persistent, severe or getting worse, or comes with vomiting, appetite loss or pain, see your vet promptly rather than reaching for a supplement.
What the research does and does not show
Research on NMN in dogs is limited. One published study in Frontiers in Pharmacology (2020) gave NMN to 5 beagles, with 5 more as controls, for 14 days to look at short-term safety, at high doses (about 1,340 mg a day). The authors reported only mild increases in creatinine and uric acid. The study did not test whether NMN helps energy or aging, and it says nothing about long-term use.
That is why Petstone describes these ingredients as ones that help support cellular energy, not as a fix for aging. Tufts Petfoodology notes that properly conducted studies are few and far between for pet supplements in general.
Resveratrol and grape worries
Many owners ask about resveratrol because it is linked with grapes. The ASPCA says tartaric acid is speculated to be the toxic part of grapes and raisins, which can cause kidney damage in dogs. Petstone makes no claim either way about resveratrol; never feed your dog grapes or raisins, and ask your vet if you have concerns about any ingredient.
Bring three questions to your vet: Is a supplement right for my dog right now? Could it interact with anything my dog takes? What should I watch for in the first month?

FAQ
What is NMN for dogs?
NMN stands for nicotinamide mononucleotide. In this product it is listed alongside NAD+ to help support cellular energy and normal metabolic function.
Is NMN proven to work in dogs?
No. The one dog study Petstone found was a 14-day short-term safety test; it did not measure energy or aging. Think of any supplement as optional and talk to your vet.
Can I give it with my dog's other medications?
Ask your vet first. The product page says to consult your veterinarian before use if your dog takes medication or has a medical condition.
How do I give the drops?
Add the weight-based serving to your dog's food once a day, from half a dropper for dogs under 22 lbs to 2 droppers for dogs over 88 lbs.
