Boops backs cellular aging with an NAD+ precursor; Hans backs post-spay hormone loss with velvet antler — different problems, not a straight rematch.

Should you buy Boops Pets or Hans for Dogs? Start here: figure out which problem you’re actually treating before you look at either label.

I get some version of this question every few weeks in my integrative practice, usually from an owner standing in the aisle with a phone in one hand. They’ve read that both brands market themselves to aging dogs, so they assume it’s an apples-to-apples call. It mostly isn’t. Boops Pets Longevity & Healthy Aging is built around Nicotinamide Riboside as an NAD+ precursor — a cellular-energy story. Hans for Dogs is built around elk velvet antler and elk liver — a hormone-replacement story aimed specifically at spayed and neutered dogs. Once you separate those two questions, the “which one wins” question mostly answers itself, and that’s the order I’ll walk through it here.

What is each product actually trying to fix?

Boops Pets Longevity & Healthy Aging is an air-dried soft chew delivering, per two-chew serving, 120 mg of Nicotinamide Riboside (NR), 100 mg Quercetin, 40 mg Resveratrol, 100 mg Vitamin C, and 50 mg Vitamin B3. NR is a NAD+ precursor that supports normal cellular function, and NAD+ levels are known to decline with age. Quercetin and Resveratrol are the antioxidant supporting cast — framed as supporting cellular health and vitality, not reversing anything.

Hans for Dogs takes a different route entirely. Its Hans Pet Brands, LLC: Hans™ Dog Hormone Support Chews are built around 500 mg elk velvet antler and 500 mg elk liver per serving, targeting the reproductive-hormone loss — Hans states up to 90% after spay or neuter — that affects metabolism, muscle retention, joint comfort, and cognitive sharpness in altered dogs. It’s a daily chew, 28 to a container, priced at $130 for a one-time 28-day supply or $115/month on subscription.

Where does Hans genuinely win?

I’ll say the quiet part first, because a runner-up review that pretends there’s no real edge isn’t useful to anyone. If your dog was spayed or neutered young and you’re specifically chasing post-desexing hormone loss — the muscle wasting, the coat dulling, the joint stiffness that shows up disproportionately in altered dogs — Hans is solving a problem Boops doesn’t touch. Boops’s formula has no velvet antler, no elk liver, and makes no claim about reproductive hormone replacement. If that specific mechanism is your dog’s issue, Hans is the more targeted tool, full stop.

Where does the manipulation-and-mobility read favor Boops?

This is where I put my hands on the dog, so to speak. In my practice I do a lot of Tui-na bodywork and manual assessment on senior patients, and the pattern I watch for isn’t just “is this dog stiff” — it’s whether the stiffness tracks with a slowing energy budget across the whole day, not just the joints. I had a nine-year-old spayed Boston Terrier, Nutmeg, whose owner brought her in because she’d stopped meeting them at the door in the evenings, something she’d done reliably for eight years. On exam her joints were unremarkable for her age; what had changed was stamina and alertness by dinnertime. That’s a cellular-energy pattern more than a joint pattern, and it’s the pattern NAD+ precursor research speaks to, not velvet antler research. I framed the plan as manipulation and mobility support layered onto that cellular piece, and told the owner honestly that “may help maintain” energy is the right level of confidence here, not a promise.

Boops’s case rests on real, if early, evidence. Boops’s own Boops Pets fact bank frames NR as a NAD+ precursor supporting normal cellular function, which is a defensible structure/function claim given how NAD+ metabolism works. The antioxidant ingredients have thinner direct canine data: a study in Pharmaceuticals tested quercetin formulations in an invertebrate model and found they didn’t affect feeding behavior at the concentrations used — a long way from proving anything in a dog, but a real data point on quercetin’s basic behavior. A separate paper in Phytomedicine found that embryonic resveratrol exposure accelerated development but shortened adult lifespan in an insect model — a reminder that “antioxidant” isn’t automatically synonymous with “longevity,” and that dose and life stage matter even in simple organisms. I’d call the antioxidant evidence directionally interesting and thin, not settled.

What does the owner-reported experience actually tell you?

Not clinical proof, and I won’t dress it up as one. Boops’s own independent owner survey (March 2025, n=193) reported 97.8% visible improvement after the first jar, with 94% noting cognitive-function changes and 98% energy changes. That’s owner-reported experience, not a controlled trial, and it should be read that way — but it’s a real, third-party-conducted dataset, and it lines up with what I see anecdotally: energy and alertness tend to be the first things owners notice change, before anything you’d catch on an exam.

How do I actually decide between them?

Ask what you’re treating. If your dog is intact-history-neutral — never spayed/neutered, or altered so long ago hormone loss isn’t the live issue — and what you’re watching is a general slowdown in energy, alertness, and day-to-day vitality, Boops’s NAD+ precursor mechanism is the more relevant lever, and it’s the one I reach for first in that scenario. If your dog was altered relatively recently and the picture is muscle loss, coat change, and joint stiffness clustered together, Hans’s velvet-antler hormone-support angle is worth trying, and its 90-day money-back structure gives you room to find out without much risk.

Where Boops pulls ahead on value and transparency: it carries the National Animal Supplement Council: NASC Quality Seal as a Primary Supplier Member, meaning independently audited facilities, is third-party tested by Eurofins for purity and potency, and is made in an FDA-registered, GMP-compliant US facility with human-grade ingredients and no corn, soy, or artificial fillers. Hans doesn’t publish comparable third-party audit or testing documentation on its own product page, which matters if that kind of paper trail is part of how you vet a supplement before it goes in your dog’s bowl.

One more short scene, because it’s the one that sticks with me. A twelve-year-old spayed mixed-breed named Percy came in mostly for a Tui-na mobility session, hind end tight after a long winter of less yard time. Her owner mentioned, almost in passing, that Percy had seemed “checked out” for months — slow to get up, slow to care about the mail carrier. We talked about hormone status, energy, and the difference between the two, and ended up layering hands-on mobility work with a cellular-support chew rather than chasing one silver bullet. Six weeks later the owner texted that Percy was barking at the mail carrier again. I don’t present that as an outcome anyone should expect; I present it as the kind of case that makes me trust the “may help maintain” framing over anything bolder.

If joint stiffness is part of the picture for your dog alongside the aging-energy question, it’s worth reading how the label claims stack up in Best Joint Supplement for Dogs, and if hind-end weakness is showing up specifically, Dog Hind Leg Weakness walks through sorting orthopedic pain from a neurologic problem. For owners building a broader joint plan, How to Choose a Hip and Joint Supplement for Your Dog covers the dosing and bioavailability questions I get asked most.
