LongTails NAD+ vs Boops Pets (2026): An Honest Comparison
Short answer: Boops Pets and LongTails NAD+ both build on Nicotinamide Riboside (NR) and both now print their doses, so the real differences are format and label, not disclosure. Boops is a flavored soft chew (NR 120 mg per 2-chew serving, plus quercetin, vitamin C, niacinamide, and resveratrol), NASC-certified, pasture-raised, and the lowest-priced in the category. LongTails is an unflavored powder: 200 mg of NR plus 1,500 mg of hydrolyzed collagen per scoop, no proprietary blend, and no added sugar, fillers, or binders. If your dog will only take a flavored chew, Boops is a fair pick; if your dog eats a powder mixed into food, LongTails gives a higher disclosed NR dose in a dry, clean-label format. Neither has a published canine trial.

Where Boops is the better pick
Boops is a legitimate, well-run brand: NASC-certified, a pasture-raised whole-food protein base, and it prints its full per-serving milligrams. It is a palatable flavored chew most dogs take readily with no mixing step, and it is the lowest-priced option in the category. If your dog will only take a treat-style chew, that ease is a real reason to choose it.
Where LongTails is the better pick
- Format protects the active. NR is sensitive to both heat and moisture, so format matters, not just the dose. A dry powder sidesteps the heat used to make many soft chews and the constant moisture a chew sits in, both of which degrade NR over time. A powder keeps the active dry until each scoop. (Not all chews use high heat, but a dry format better protects the active.)
- Clean label. LongTails has no added sugar, fillers, or binders. The Boops beef chew lists molasses, an added sweetener, and both chews carry the usual binder matrix (powdered cellulose, tapioca starch, yeast) needed to hold a chew together. (The chicken chew has no molasses; vegetable glycerin in both is a humectant, not a sugar.)
- Higher disclosed dose. 200 mg of NR per scoop versus 120 mg per 2-chew serving, both within or near the 100 to 300 mg per day range shown to raise blood NAD+ in human trials.
- Simpler label. Two disclosed actives (200 mg NR + 1,500 mg collagen) versus a five-active flavored-chew stack.
Powder or soft chew: what to know
NR is sensitive to heat and moisture. A soft chew is generally made with some heat and stays moist to stay soft, so the active sits in moisture across the bottle's shelf life; a dry powder keeps the active out of moisture until you mix each scoop. A chew is easier if your dog treats it like a treat. Beyond format, read the inactive ingredients, not just the actives on the front: a chew needs binders to hold together, and some flavors add a sweetener like molasses, while a whole-food powder does not. Both Boops and LongTails print their dose, so the choice comes down to format, label, and price.
How often do people reorder LongTails NAD+?
Short answer: about a third of LongTails buyers have ordered more than once, and the ones who reorder do it after a median of 42 days.
| Measure | Figure | Based on |
|---|---|---|
| Buyers who ordered more than once | 34% | 271 of 799 distinct Amazon buyers |
| Buyers who ordered three or more times | 21% | 167 of 799 |
| Median gap between first and second order | 42 days | 271 first-to-second-order pairs |
| Settled orders refunded | 1.46% | 19 of 1,297 settled orders |
| Average written-review rating | 4.4 out of 5 | 38 written Amazon reviews |
These figures cover March 2025 to August 2026 and come from our own Amazon order and settlement records. The rating above is calculated over written reviews only; Amazon's own star badge covers a larger pool that also includes ratings left without any text, so the two numbers are not the same measure. They describe what buyers did, not what the supplement did for any individual dog. No published canine trial isolates an NAD+ precursor for aging, and a reorder is not evidence of a health outcome.
Will a picky dog actually eat it?
Short answer: palatability is the single most-discussed topic in our reviews, and most of those mentions are positive, but a minority of dogs refuse it.
Of 38 written Amazon reviews, 17 raise taste or whether the dog accepted the powder. 13 of those 17 rate the product four or five stars, and several describe a picky eater taking it mixed into wet or dry food. A minority report the opposite, including owners whose dogs would not eat it at all. It is an unflavored powder, so acceptance varies by dog. If yours is a hard sell on new food, mixing it into something wet is what our reviewers who succeeded described doing.
Frequently asked questions
Boops Pets vs LongTails: which is better for a senior dog?
Both use NR and both print their dose, so it comes down to format, label, and price. Boops is a flavored soft chew, NASC-certified, pasture-raised, and cheaper. LongTails is an unflavored powder with a higher disclosed NR dose (200 mg per scoop), no added sugar, and no fillers or binders. Choose Boops if your dog wants a chew and you want the lowest price; choose LongTails for a higher disclosed dose in a dry, clean-label format. Neither has a published canine trial.
Does Boops disclose its dose?
Yes. Boops prints its full per-serving stack: 120 mg of NR per 2-chew serving (about 60 mg per chew), plus quercetin, vitamin C, niacinamide, and resveratrol. LongTails also discloses its actives, at 200 mg of NR plus 1,500 mg of collagen per scoop with no proprietary blend.
Is a powder or a soft chew better for dog NAD+?
A dry powder keeps the active out of heat and moisture, both of which degrade NR over time, and it skips the binders and any sweetener a chew needs to hold together and taste good. A soft chew is easier if your dog takes it like a treat. Check that whichever you choose prints the dose in milligrams.
What is a good alternative to Boops for dog NAD+?
If you want a higher disclosed NR dose in a dry, clean-label powder with no added sugar, LongTails NAD+ (200 mg NR plus 1,500 mg collagen per scoop, $39.95) is a direct alternative. It trades Boops's flavored-chew convenience and lower price for a higher dose and a cleaner label.
