Healthy Petz Liquid Collagen Reviews UK (2026): Honest Comparison

Quick answer for UK owners: Pure Majesty is our clear pick. Pure Majesty Pets Liquid Collagen for Dogs costs £25 with free worldwide shipping and duties & VAT prepaid, and each 2 mL serving combines a dual-collagen core (about 462 mg hydrolysed Type I & III plus about 40 mg undenatured Type II) with salmon oil, hyaluronic acid, L-glutamine, ginger and an S. boulardii postbiotic — joints, skin & coat and gut in one bottle, with a certificate of analysis on every batch and a 4.6/5 rating from 1,085 reviews. Healthy Petz, a US brand now selling to Britain at £39 through its own website, prints bigger numbers: 900 mg of marine collagen, 40 mg UC-II, 400 mg omega-3 and 50 mg vitamin C in what its page calls a single small serving. Those figures add up to about 1,390 mg of listed ingredients for a 1 mL dose — more than a millilitre of liquid can comfortably hold — and its main Trustpilot page scores 1.2/5, dominated by subscription and refund complaints. Bigger numbers you can't check, from a company reviewers struggle to reach, don't make a better supplement. A supplement supports health — talk to your vet before starting one.

Healthy Petz has built visibility around its Premium Liquid Collagen, and it now courts British buyers with a UK-facing shop priced in pounds and "Tracked GB Shipping". Pure Majesty Pets plays in the same premium liquid-collagen space — but builds the formula, and the buying experience, differently. So if you're in the UK and weighing one against the other, what actually separates them?

This comparison breaks both brands down on the criteria that matter to a British owner: collagen and joint actives, whole-body coverage, whether the label numbers hold up to arithmetic, the real price per day in pounds, delivery and import charges, customer experience, and the UK-made alternatives you could buy instead.

TL;DR: Pure Majesty Pets collagen pairs a dual-collagen joint core with a skin-and-gut layer — salmon oil, hyaluronic acid, L-glutamine, ginger and an S. boulardii postbiotic — at amounts small enough to physically fit in a thin 2 mL liquid, with a certificate of analysis on every batch, free worldwide shipping and no customs bill. Healthy Petz's current UK page lists larger single numbers (collagen, omega-3, vitamin C) but those numbers do not reconcile with the size of the serving it describes, its listing has changed over time, and its public review record is dominated by service, subscription and refund complaints. On breadth, verifiability, UK cost per day and after-sale care, Pure Majesty leads.

At-a-Glance Comparison

Both columns reflect each brand's own published information, checked on 7 October 2026. Serving sizes differ — Pure Majesty describes a 2 mL serving, Healthy Petz a 1 mL serving for small dogs (its ingredient heading literally reads "each 1mg serving") — so read the milligrams as each brand's stated per-serving amounts, not as a verified like-for-like test.

Where Healthy Petz Is Strong

Let's give Healthy Petz its due, because the formula concept is sensible and some of its choices are good ones.

• High stated single doses. Per serving, Healthy Petz lists more hydrolysed collagen (900 mg), a stated 400 mg of omega-3 and 50 mg of vitamin C. If the biggest number on a label is your only criterion, that is where it leads — with the caveat that those figures are worth reading critically (see the dose-math reality check below).
• It includes UC-II. Like Pure Majesty, Healthy Petz includes undenatured Type II collagen (40 mg) alongside its hydrolysed Type I & III — the cartilage-specific form studied in canine force-plate trials, and one that many cheaper "joint" products skip.
• Marine collagen. Its FAQ says the collagen is marine, from wild-caught fish, with no chicken, beef, poultry or dairy — a genuine plus for dogs on a fish-based elimination diet.
• Easy to give. The current page describes the liquid as tasteless and mixed into food once daily, with weight-based directions.
• A money-back promise. The page advertises a 60-day money-back guarantee — though, as the review section below shows, some customers report difficulty getting refunds honoured.

So the concept is fine. Three things hold it back. First, its label numbers do not survive basic arithmetic — roughly 1,390 mg of listed ingredients in a 1 mL dose is not physically plausible for a pourable liquid, and there is no published batch analysis to settle it. Second, the listing has shifted: earlier versions of the same product were sold with MSM, hyaluronic acid and a bacon flavour, while the current UK page lists omega-3 and vitamin C instead and calls the liquid tasteless — so check the bottle you actually receive. Third, it is narrow on gut support: no L-glutamine, no ginger and no probiotic, prebiotic or postbiotic. That is exactly the layer Pure Majesty adds.

Where Pure Majesty Stands Apart

The clearest way to see the difference is not to trade headline milligrams — it is to count how many distinct jobs each 2 mL serving of Pure Majesty Pets Liquid Collagen covers at once, at amounts that make physical sense. Grouped by the job each ingredient does:

Skin & coat.

• Hydrolysed collagen peptides Type I & III — about 462 mg per 2 mL: the structural collagens of the dermis, supporting skin strength, hydration and coat condition.
• Salmon oil: a source of omega-3 fatty acids — the nutraceutical family with the strongest evidence behind it in canine joint research, and a staple of skin-and-coat routines.
• Hyaluronic acid: a natural component of skin and joint fluid. Not on Healthy Petz's current page.

Joints & mobility.

• Undenatured Type II collagen — about 40 mg per 2 mL: the intact cartilage form studied in force-plate gait trials in dogs. Both brands include it — shared common ground.
• Ginger root extract: a traditional botanical in the blend that Healthy Petz does not list.

If joints are your dog's main concern, see how collagen ranks against glucosamine, omega-3s and green-lipped mussel in our guide to the best joint supplements for dogs.

Gut & digestion — a layer Healthy Petz does not list.

• L-glutamine: an amino acid the cells of the gut lining use as fuel — relevant to the gut–skin connection in itchy dogs. Healthy Petz does not list it.
• Tyndallised Saccharomyces boulardii postbiotic: heat-inactivated (not a live probiotic), included for gut support. Healthy Petz's collagen formula lists no probiotic, prebiotic or postbiotic.

Here is the honest summary: Healthy Petz prints bigger numbers on collagen, omega-3 and vitamin C. Pure Majesty covers more ground at once — joints, skin & coat and gut — with hyaluronic acid, L-glutamine, ginger and a postbiotic on top of the dual-collagen core, at amounts that physically fit the serving, and with a certificate of analysis on every batch. A number that can't fit in the bottle is a marketing claim; a realistic number from a batch-tested product is something you can rely on.

1. The gut layer the competition doesn't have

Our Liquid Collagen for Dogs adds L-glutamine and a heat-stable S. boulardii postbiotic to the collagen base. If your dog's issues include a sensitive stomach as well as a dull coat or itchy skin — common in breeds such as the French Bulldog, Westie and Labrador — this is the clearest point of difference.

2. Multi-type collagen plus a whole-dog stack

Both formulas pair hydrolysed Type I & III with undenatured Type II. Pure Majesty then builds outward with salmon oil, hyaluronic acid, ginger, L-glutamine and a postbiotic, so a single bottle supports joints + skin + coat + gut, each with a dedicated ingredient behind it.

3. Honest, physically plausible amounts

We describe our collagen amounts as approximate formulation figures per 2 mL reference serving — about 462 mg and 40 mg — and they sit comfortably inside a thin liquid you can drop onto food. A 2 mL serving of a water-based liquid weighs a little over 2 g, so there is room for the actives and the liquid that carries them. That is the kind of label you can take at face value.

4. Batch-level quality checks

Every batch of Pure Majesty is made in North America in a GMP facility and comes with a certificate of analysis. Healthy Petz's product page does not publish batch testing.

5. Free worldwide shipping with duties & VAT prepaid

Pure Majesty ships free worldwide, including to the UK on a DDP (delivered duty paid) basis: duties and VAT are prepaid at checkout, so the price you see in pounds is the price you pay — no courier card, no handling fee, whatever the size of your order.

A quick reality check on the dose math

One thing worth doing with any comparison like this is simple arithmetic on the label. Healthy Petz's current UK page lists, under the heading "What's in each 1mg serving": 900 mg hydrolysed marine collagen + 40 mg UC-II + 400 mg omega-3 + 50 mg vitamin C = about 1,390 mg of listed ingredients. Its directions start at 1 mL a day for dogs under 25 lb (about 11 kg). The problem is a physical one: 400 mg of oil alone takes up roughly 0.4 mL, because oils are lighter than water, which would leave about 0.6 mL for nearly a gram of collagen and vitamin C — plus the water needed to make it pour. Dry collagen powder on its own takes up more room than that. The numbers do not add up cleanly for a thin, pourable liquid.

To be fair, this is an open question, not an accusation — there are benign explanations. The heading's "1mg serving" is clearly a typo, so the amounts may refer to a larger serving than 1 mL; "Omega 3 – 400mg" may mean 400 mg of fish oil rather than pure omega-3; or the figures may be rounded or simplified. The listing has also changed over time (earlier versions showed MSM, hyaluronic acid and a bacon flavour). The sensible move for a UK buyer is to check the serving size on the bottle itself before deciding, and to ask the brand how those milligrams fit into the dose your dog will actually get.

This is where transparency, rather than headline milligrams, becomes the thing to compare. Pure Majesty describes modest, realistic amounts in a genuine thin-liquid 2 mL serving, names every ingredient, and backs each batch with a certificate of analysis. When one label prints bigger numbers that can't fit in the dose and the other prints numbers that can, the choice is not close.

Buying Each in the UK: Price per Day, Delivery, VAT & Duties

Because Healthy Petz is a US brand and Pure Majesty is made in North America, British buyers are importing either way. Here is what that means in practice, using each brand's own UK prices and serving directions (checked 7 October 2026).

These are cost calculations from the brands' published prices and directions, not a clinical or like-for-like dose comparison, and they exclude any delivery charge on Healthy Petz's side. For a Labrador, Golden Retriever or German Shepherd — large breeds that the Royal Veterinary College's VetCompass data flag as more prone to osteoarthritis — Pure Majesty works out at roughly a third to two-thirds of Healthy Petz's daily cost.

Import VAT and duty: what UK rules say. Under HMRC rules on goods bought from abroad, a seller should include VAT in the price for orders of £135 or less; above £135 — a typical multi-bottle stock-up — VAT on the full value plus any customs duty is normally collected by the delivery company before the parcel is handed over, and the parcel is held until you pay. Healthy Petz's product page shows "Tracked GB Shipping" but does not say where orders ship from or how VAT and duty are handled, so check at checkout. Pure Majesty removes the question: every UK order ships free and DDP, with duties and VAT prepaid, however many bottles you buy.

Amazon and subscriptions. Healthy Petz says it sells only through its official site and that listings on Amazon or eBay are "not us" — so a Healthy Petz bottle on Amazon UK is not an authorised sale. Its site offers subscriptions, and several Trustpilot reviewers (including UK reviewers) say they were signed up without realising; read the checkout carefully. On Pure Majesty's UK page you can buy a single bottle at £25 or a 3- or 5-bottle bundle.

What Real Customers Actually Say

Labels tell you what is in the bottle. Reviews tell you what happens after you click buy — whether the product delivers, and whether anyone answers when something goes wrong. Both matter, and the public record is worth reading before you choose.

Pure Majesty: what dog owners report

Pure Majesty Pets Liquid Collagen for Dogs currently holds a 4.6/5 average across 1,085 customer reviews on our UK product page. The themes that repeat most are coat softness, easier movement in older dogs, and how simply the drops go onto food. In their own words:

"I noticed a change in my little Luke, his coat is so soft and helps with his joints." — JanieCummerata, verified customer

"This liquid collagen is easy to give and my dog likes it. I've noticed better mobility and a shinier coat. It also seems gentle on the stomach." — Yunaiky, verified customer

"Small bottle but concentrated formula. Good daily supplement for active or senior dogs." — Tristin Lawrence, verified customer

We publish the reviews that are not flattering too, because a review page you can only find the good half of is not a review page. Every batch ships with a certificate of analysis, and our support team is reachable by email at every stage of an order — because a supplement you cannot get answers about is not a supplement you should be giving your dog.

Healthy Petz: what the public review record shows

This is where the two brands separate on something the ingredient table cannot capture. Healthy Petz has two Trustpilot profiles. When we checked on 7 October 2026, the healthypetz.com profile showed a TrustScore of 1.2/5 from 210 reviews, 96% of them one-star; the newer shophealthypetz.com profile showed 4.0/5 from 197 reviews, with 19% one-star. The recurring complaint themes across both include:

• Subscriptions customers say they did not knowingly agree to, with recurring charges appearing afterwards — including from reviewers in Great Britain.
• Customer service that is hard to reach — repeated reports of emails going unanswered.
• Refunds that reviewers say were not honoured despite an advertised money-back guarantee.
• Delivery problems — long delays, and some parcels reported as arriving damaged.
• Mixed results on itching, with some reviewers reporting no change or a worse itch.

Read them yourself before deciding: Trustpilot — healthypetz.com and Trustpilot — shophealthypetz.com. These reflect individual customer experiences as published on Trustpilot, not our own testing, and review pages change over time. Healthy Petz's own page, for its part, claims a 4.7 rating from more than 50,000 pet parents.

Put the two records side by side and the pattern is hard to miss. A supplement is a relationship, not a single transaction — you will reorder it, you may need to pause it, and one day you may need someone to answer an email. That part of the purchase deserves as much weight as the milligrams.

UK Alternatives to Healthy Petz

If you'd rather buy from a British brand or a UK high-street retailer, these are the options UK owners usually compare (prices from the retailer named, checked October 2026):

• Pawable Collagen for Dogs ("Collar-gen") — a UK powder combining hydrolysed bovine collagen, UC-II and hydrolysed eggshell collagen; £29.99 for 225 g with free delivery on Pawable's site. The closest UK match to a dual-collagen formula, in powder rather than liquid form.
• YuMOVE Joint Care for Adult Dogs (Lintbells) — the best-known UK joint supplement, but it contains no collagen: glucosamine, green-lipped mussel and hyaluronic acid; £22 for 80 tablets at Boots. See our YuMOVE review.
• Pooch & Mutt collagen chews — beef-collagen chews (61–70% beef collagen) launched in 2026: a collagen-rich treat rather than a dosed supplement.

For a full UK buyer's guide with a £ comparison table, see our best collagen for dogs UK 2026 guide.

When a supplement isn't enough. The PDSA's guidance is that joint supplements help some dogs but not all, and they are safe to use alongside common arthritis medicines. VetCompass data from UK vet practices show osteoarthritis is recorded in about 2.5% of dogs each year — around 200,000 UK dogs — mostly older and heavier dogs. If your dog is limping, struggling on the stairs or reluctant to walk, see your vet: prescription options such as meloxicam or Librela (both POM-V) may be needed, with collagen as daily support alongside. Remember too that in the UK supplements are sold as complementary feed under feed law enforced by Trading Standards, so no supplement — ours or anyone else's — may claim to treat disease.

Which Should You Choose?

Choose Healthy Petz if:

• The single biggest number printed on a label is your main criterion, and you're comfortable that it is unverified
• Your dog needs a marine-only collagen source
• You have a small dog (under ~11 kg), where its 1 mL serving keeps the daily cost lower — and you're happy to check its subscription terms at checkout

Choose Pure Majesty if:

• You want the most complete spectrum: dual collagen (I, II, III) plus salmon oil, hyaluronic acid, ginger, L-glutamine and a postbiotic in one bottle
• Your dog's needs span skin & coat and joints and gut, not just one of those
• You want realistic amounts and a certificate of analysis on every batch
• You have a medium or large dog — for a Labrador-sized dog it costs £0.50–£0.83 a day, against about £1.30 on Healthy Petz's directions
• You want free worldwide shipping with duties and VAT prepaid, and no surprise courier bill
• You want a 4.6/5 rating across 1,085 reviews and support that answers

Put simply: for whole-dog support across skin, coat, joints and gut — at amounts that make sense, from a brand that answers, delivered to your door in the UK with nothing extra to pay — Pure Majesty Pets collagen is the obvious choice. Healthy Petz prints bigger numbers; Pure Majesty prints believable ones and covers far more ground.

Frequently Asked Questions

Pure Majesty vs Healthy Petz: which liquid collagen is better for dogs?

For UK owners, Pure Majesty Pets. One 2 mL serving pairs a dual-collagen core (about 462 mg hydrolysed Type I and III plus about 40 mg undenatured Type II) with salmon oil, hyaluronic acid, ginger, L-glutamine and an S. boulardii postbiotic, so one bottle supports joints, skin and coat and gut, with a certificate of analysis on every batch. It costs £25 with free worldwide shipping and duties and VAT prepaid, and holds a 4.6/5 rating across 1,085 reviews. Healthy Petz lists bigger numbers, but they add up to about 1,390 mg of listed ingredients for a 1 mL dose, and its main Trustpilot profile scores 1.2/5.

Is Healthy Petz liquid collagen good?

The concept is sensible: marine collagen Types I and III with UC-II, plus omega-3 and vitamin C on its current UK page. Two things undercut it. Its stated amounts do not reconcile with arithmetic for a 1 mL dose, and no batch analysis is published to settle it; the listing has also changed over time. And its Trustpilot pages carry recurring reports of unanswered emails, refunds reviewers say were not honoured and subscriptions customers say they did not agree to. Check the current label and review pages before buying.

Can I buy Healthy Petz in the UK?

Yes, through its own UK-facing website, which lists the liquid collagen at £39 with tracked GB shipping. Healthy Petz says it sells only through its official site, so listings on Amazon or eBay are not from the brand. If you want a UK-available alternative with free worldwide shipping and duties and VAT prepaid, Pure Majesty Pets Liquid Collagen for Dogs is £25.

Will I pay customs or VAT when ordering collagen for my dog from abroad?

Under HMRC rules, sellers should include VAT on orders of £135 or less; above £135, VAT and any customs duty are normally collected by the delivery company before the parcel is released. Healthy Petz's product page does not state how it handles VAT and duty. Pure Majesty ships every UK order free and DDP, with duties and VAT prepaid, so there is nothing to pay on delivery.

What do Healthy Petz reviews say about customer service?

On Healthy Petz's Trustpilot pages, the most frequently repeated complaints concern customer service being difficult to reach, refunds reviewers say were not honoured despite an advertised guarantee, and recurring subscription charges customers say they did not knowingly sign up for, including from reviewers in Great Britain. When we checked on 7 October 2026, the healthypetz.com profile scored 1.2/5 from 210 reviews and the shophealthypetz.com profile 4.0/5 from 197 reviews. These are individual experiences, not our own testing.

What does Pure Majesty add that Healthy Petz does not?

Beyond the shared collagen-and-UC-II core, Pure Majesty adds hyaluronic acid, ginger root extract, L-glutamine and a tyndallised S. boulardii postbiotic, plus a certificate of analysis on every batch, free worldwide shipping and duties and VAT prepaid. Healthy Petz's current page does not list hyaluronic acid, ginger, L-glutamine or any probiotic, prebiotic or postbiotic.

Which has the higher collagen dose?

Healthy Petz prints the higher number: 900 mg of hydrolysed marine collagen per stated serving, against Pure Majesty's approximately 462 mg per 2 mL. Whether that printed number is what your dog actually gets is the open question, because the listed ingredients total about 1,390 mg for a 1 mL dose and no batch testing is published. Pure Majesty's amounts are realistic for a thin liquid and every batch carries a certificate of analysis.

Can a 1 mL liquid really hold 1,390 mg of listed ingredients?

It is worth checking. Healthy Petz's page lists 900 mg collagen, 40 mg UC-II, 400 mg omega-3 and 50 mg vitamin C per serving, and its directions start at 1 mL a day. The oil alone takes up roughly 0.4 mL, leaving little room for nearly a gram of collagen and vitamin C plus the water needed to make it pour. There are innocent explanations, such as a larger true serving or rounded figures, so check the serving size on the bottle before you buy.

Can these supplements treat my dog's arthritis or allergies?

No. Both are nutritional supplements that support normal joint, skin, coat and gut health; in the UK they are sold as complementary feed and may not claim to treat or prevent disease. Use them as part of your vet's plan, not instead of it, and talk to your vet before starting a new supplement, especially if your dog has a medical condition or takes medication.

Always talk to your vet before starting any supplement, particularly if your dog has an existing medical condition, takes medication, or is pregnant or nursing. This article is for general information and is not a substitute for veterinary advice.
