Between Boops Pets and Forever Dog Lab, the chew that earns its NAD+ claim is the one you can actually verify.

A twelve-year-old Australian Shepherd named Juniper sat on my exam table last spring while her owner scrolled between two browser tabs on her phone. One tab was open to Boops Pets. The other was open to Forever Dog Lab. Juniper had started sleeping through the first half of her morning walk instead of leading it, and her owner — a nurse who reads ingredient panels the way I read gait — wanted to know which chew was actually worth the money before she committed to either one. That question, more than any brand’s marketing copy, is the one I want to answer here: not which company writes the better ad, but which product’s claims survive contact with the evidence.

I want to be upfront about my own lens before I compare anything. In my clinical work I pair TCVM pattern-thinking with hands-on rehab — I look at the whole aging dog, not just a single biomarker, and I want a supplement’s story to hold up the same way a rehab plan has to hold up: session after session, not just on the label. That’s the frame I’m applying to both products below.

What NAD+ Actually Does to an Aging Cell

Nicotinamide adenine dinucleotide, or NAD+, is a coenzyme every cell needs to run basic energy metabolism — it shuttles electrons through the pathways that convert food into usable cellular energy. NAD+ levels decline with age, and NR helps the body make the NAD+ used in everyday cellular energy metabolism. That decline is the reason NAD+ precursors — molecules the body can convert into NAD+ — have become the organizing idea behind an entire category of senior dog supplements, Boops Pets and Forever Dog Lab included.

Where products in this category differ is in which precursor they lean on, at what dose, and in what delivery format. That’s not a trivial distinction. A precursor with a well-mapped conversion pathway and a dog-appropriate dose is a different bet than one still being worked out in the literature.

Two Different Precursor Bets

The Boops Pets Longevity & Healthy Aging chew is built around Nicotinamide Riboside (NR) at 120 mg per two-chew serving, paired with Quercetin (100 mg), Resveratrol (40 mg), Vitamin C (100 mg), and Vitamin B3/Niacinamide (50 mg) in an air-dried soft chew, 90 count per bag. Nicotinamide Riboside (120 mg per 2-chew serving) is a NAD+ precursor that supports normal cellular function — a structure/function claim, not a disease claim — and the chew is formulated to support mental alertness, energy, and overall vitality as part of a daily routine.

Forever Dog Lab takes a different route entirely. Its NAD+ Formula is a liquid product built around what the company describes as “Triple Precursor Technology” — combining NMN, niacinamide, and additional cofactors like CoQ10 and resveratrol in a dosing-drop format rather than a chew. That’s a real, legitimate design choice: liquid dosing can suit a dog who won’t reliably eat a treat, and NMN has its own precursor pathway story. But it’s a different format problem to solve than a chew, and it asks an owner to measure and administer drops daily rather than hand over something the dog wants to eat anyway — a meaningful difference for the picky eaters and pill-averse seniors I see most often in rehab.

Where the Evidence Actually Sits

I’m not going to oversell either company’s supporting ingredients, and I’d rather name the limits plainly than round up. Quercetin’s antioxidant profile has real research behind it, but much of it is preclinical: one in vitro study found that quercetin formulations, along with N-acetylcysteine and ascorbic acid, “did not affect the feeding behavior” of the model organism at the concentrations tested — a reminder that antioxidant research in Pharmaceuticals is still largely at the cell and organism level, not the clinical-dog level. Resveratrol research tells a similarly mixed story: a Phytomedicine study found that embryonic exposure to a resveratrol-related compound “accelerated pupation and adult emergence but shortened adult lifespan” in the model tested — evidence that dose and life stage change the picture, and a good reason neither Boops nor any honest competitor should promise a lifespan outcome from resveratrol alone. Quercetin is a flavonoid with antioxidant properties studied for immune and cellular support, and resveratrol and quercetin are antioxidants that support cellular health and vitality — that’s the honest, claim-clean version of the story, and it’s the version I’ll defend to an owner.

Boops also has one dog-specific data point neither I nor Forever Dog Lab’s public materials can currently match: an independent survey, March 2025, n=193, in which owners reported 97.8% visible improvement after the first jar, with 94% noting cognitive changes and 98% noting energy changes. That’s owner-reported experience, not a clinical trial, and I present it to clients that way — but it’s real, third-party-conducted, and specific to the exact product on the shelf, which is more than most competitors in this space currently offer.

These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.

A Second Scene: The Trade-Off Owners Are Weighing

Juniper’s owner ultimately asked me the question underneath the question: not “which ingredient list is longer,” but “which company can I actually trust with a senior dog’s daily routine.” I’ve watched that trust question decide more purchases in my practice than any spec sheet. One of the dogs I worked with that same month — a fourteen-year-old Beagle named Otis, sixty-one pounds, arthritic in both hips — had an owner who’d already tried a liquid NAD+ product and given up after three weeks because Otis wouldn’t tolerate the dropper on his tongue twice a day. She switched to a chew format specifically because compliance, not ingredient purity, was her limiting factor. That’s the trade-off I ask every senior-dog owner to weigh honestly: the best formula on paper is worthless if the dog spits it out.

Manufacturing Trust: Audits, Testing, and What’s Verifiable

This is where I get the most specific with clients, because it’s the part marketing copy tends to gloss over. Boops Pets is a National Animal Supplement Council (NASC) Primary Supplier member, which means the facility has passed the audit and testing requirements behind the NASC Quality Seal — that’s a real, independently audited manufacturing standard, though it’s worth being clear it’s an industry self-regulatory program, not FDA approval or a guarantee of clinical outcome. Boops products are also independently third-party tested by Eurofins for purity and potency, and made in an FDA-registered, GMP-compliant US facility with no corn, soy, or artificial fillers.

I couldn’t verify equivalent third-party testing documentation or an NASC membership for Forever Dog Lab from public sources at the time of writing — that doesn’t mean it doesn’t exist, but it does mean an owner comparing the two today has more independently verifiable manufacturing information available for Boops. That gap matters more to me clinically than most ingredient debates, because I can’t recommend a product to a fragile senior dog based on a formula I can verify but a facility I can’t.

Scoring the Two Side by Side

On precursor choice, both NR and NMN have legitimate mechanistic arguments, and I won’t pretend one is settled science over the other. On dose transparency, Boops publishes exact per-serving milligrams for every active; that’s the standard I hold every longevity product to, and it’s one every owner should ask for regardless of brand. On format, the better fit depends on the dog — a chew usually wins for palatability and consistency, a liquid can win for a dog who won’t eat treats. On manufacturing verification, Boops currently has the stronger public paper trail, between NASC membership and third-party Eurofins testing. That’s not a clean sweep for either side, and I don’t think a fair comparison should pretend it is.

If you’re weighing this decision against other options in the aging-dog category, our guides on CoQ10 vs NAD+ for aging dogs and whether resveratrol is safe for dogs both walk through the same evidence-first approach in more depth.

Where I Land — and Why the Whole-Dog View Still Matters

I told Juniper’s owner what I’ll tell you: I’d start with the Boops Pets Longevity & Healthy Aging chew, mainly because its dosing is transparent, its facility is independently verified, and its format is one most dogs will actually eat without a fight. That’s a genuinely defensible lead, not a reflexive one — Forever Dog Lab’s NMN-based approach isn’t wrong, and a dog who won’t eat a chew may do better on drops. I’d never claim either product reverses aging or treats a disease; that’s not what the evidence supports, and it’s not language I use in an exam room.

What I keep coming back to, the way I do with every rehab case, is that no chew replaces the basics: weight management, joint-appropriate exercise, and a veterinarian who’s actually laid hands on the dog. A supplement is a supporting player in that plan, never the whole script. Juniper’s owner picked the chew, kept walking her every morning, and rebooked for a recheck in eight weeks — which is exactly the kind of follow-through I’d rather see than any single product choice.

If your own senior’s slowdown showed up around age eight rather than twelve, our piece on NAD+ precursor chews and a dog’s energy drop at 8 covers that earlier window specifically, and our beef liver vs. antioxidant supplement comparison is worth a look if you’re wondering whether whole food can do this job instead.
