If your dog is slowing down on walks, showing stiffness after rest, or you simply want to support their joints proactively, you’ve probably come across two popular options in New Zealand: Antinol Plus and Nuvetra Advanced Joint Support.
Both supplements are made in New Zealand and use green-lipped mussel (GLM) as a key ingredient for joint support. However, they take quite different approaches in their formulations.
Antinol Plus is a long-established joint supplement widely used in veterinary clinics and focuses primarily on marine lipids derived from green-lipped mussel and krill oil.
Nuvetra Advanced Joint Support combines green-lipped mussel with additional ingredients including concentrated omega-3 fish oil, curcumin, and PEA (palmitoylethanolamide) to provide broader nutritional support for joints, mobility, skin, and overall wellbeing.
This guide compares the ingredients, dosing, pricing, and suitability of each product to help you decide which option may best suit your dog.
Ingredients Compared
The table below is where the real differences show up. Antinol Plus contains a marine lipid blend per capsule. Nuvetra’s capsules are deliberately larger because they contain multiple active ingredients in one formula.
| Ingredient | Nuvetra™ | Antinol® Plus |
|---|---|---|
| Green-Lipped Mussel (GLM) Oil | 40mg (Equivalent to 5000mg fresh GML) | 30 mg per capsule (PCSO-524®) |
| Omega-3 (EPA & DHA) | 1225mg VivoMega® 4030TG – concentrated 40/30 EPA/DHA ratio, natural triglyceride form | 20mg Krill oil |
| Curcumin | 100mg HydroCurc® – high-bioavailability form | ✗ Not included |
| PEA | 100mg – supports normal inflammatory responses | ✗ Not included |
| Total active ingredients | 4 actives | 2 actives |

A closer look at Nuvetra’s four ingredients
Each ingredient in Nuvetra is chosen for a specific reason, with no vague proprietary blend to hide behind.
Green-Lipped Mussel GlycOmega®
Core active
NZ green-lipped mussel oil is the same hero ingredient category used in Antinol Plus. It is rich in unique omega-3 fatty acids that support cartilage health, joint comfort, and mobility.
Omega-3 VivoMega® 4030TG
40% EPA / 30% DHA
A premium fish oil in natural triglyceride form. Omega-3 supports joint flexibility, skin hydration, coat condition, and overall wellbeing.
HydroCurc® Curcumin
High bioavailability
Standard curcumin is poorly absorbed. HydroCurc® uses a patented water-dispersible format designed to improve uptake. It supports a balanced inflammatory response and post-activity joint comfort.
PEA Palmitoylethanolamide
Natural signalling molecule
PEA is a naturally occurring fatty acid amide that helps support the body’s normal comfort and inflammatory response pathways, helping promote ease of movement without being a pharmaceutical medication.
Why does the stack matter?
Joint discomfort in dogs is rarely a single-pathway issue. GLM supports joints from the marine lipid angle, omega-3 supports the body systemically, curcumin supports a balanced inflammatory response, and PEA supports comfort pathways.
Bringing these ingredients together gives Nuvetra a broader support profile than single-focus joint supplements.
Dosage & How to Give
| Nuvetra™ | Antinol Plus |
|---|---|
| Weight-based daily dosing | Weight-based daily dosing |
| 1 capsule per 10 kg body weight daily | Follow label dosing guide based on body weight |
| No loading phase required | Initial loading phase commonly recommended |
| Capsule can be given whole or opened over food | Small capsules can be given whole or hidden in food |
| Suitable for dogs of all sizes | Suitable for dogs of all sizes |
| Store in a cool, dry place | Store according to label directions |
The two supplements use different dosing approaches. Nuvetra uses a straightforward weight-based daily dose, while Antinol Plus uses a loading and maintenance schedule based on the manufacturer’s directions.
Always follow the product label or your veterinarian’s advice when introducing a joint supplement.
Pricing and Value in NZ
As of 2026, Antinol Plus 60 capsules retails at approximately $63–$68 NZD across NZ vet clinics and pet stores.
Nuvetra is available through Vetpost, with four pack sizes:
| Pack Size | Price | Cost Per Capsule | Best For |
|---|---|---|---|
| 60 caps | $90 | $1.50 / capsule | Small dogs / trial |
| 120 caps | $139 | $1.16 / capsule | Best seller |
| 180 caps | $199 | $1.11 / capsule | Great value |
| 240 caps | $249 | $1.04 / capsule | Multi-dog / large breeds |
On a pure per-capsule basis, Nuvetra is priced higher than Antinol. But the comparison gets more interesting when you factor in what each capsule contains.
Antinol’s marine lipid formula contains green-lipped mussel oil and krill oil. Nuvetra’s capsule includes GLM oil, a concentrated 40/30 EPA/DHA omega-3, HydroCurc® curcumin, and PEA: four actives in one formula.
For a 20 kg dog on Nuvetra, that is 2 capsules daily. The 120-capsule pack lasts 60 days at $139, which works out to roughly $2.32 per day.
That is the cost of a broader, vet-formulated joint and skin support regime in one product.
Which dog is each suited for?
| Choose Nuvetra if your dog… | Antinol Plus may suit if… |
|---|---|
| Has stiffness, mobility concerns, or diagnosed joint issues | Your dog has mild or early-stage joint concerns |
| Is a large or active breed with high joint demands | You prefer a smaller capsule that is easy to hide |
| Has skin issues alongside joint concerns | Your dog is already doing well on Antinol |
| Is already on Antinol but you want broader support | You want a supplement with a longer track record of studies |
| You want full ingredient transparency with no blends | Budget is a primary consideration |
| You prefer one supplement that covers multiple support pathways | You prefer a simpler marine lipid formula |
| Is older and may benefit from broader wellbeing support |
Our Verdict
Antinol Plus is a quality supplement and a genuine step up from basic glucosamine and chondroitin formulas. It has a long history of use and remains a popular choice for dogs needing marine-lipid joint support.
Nuvetra Advanced Joint Support takes a broader formulation approach. It brings together green-lipped mussel, concentrated omega-3, HydroCurc® curcumin, and PEA in one capsule.
For dogs with moderate joint concerns, larger breeds, active dogs, older dogs, or dogs needing both joint and skin support, Nuvetra may be the more comprehensive choice.
The bottom line: if Antinol Plus is the established marine-lipid option, Nuvetra is the broader multi-active formula. It is not just more ingredients, it is a carefully selected ingredient stack, formulated by veterinary expertise, made in a New Zealand facility, with transparency about what is in every capsule.
If your dog is currently on Antinol and you feel like you want to do more, Nuvetra may be a natural next step.
