Mussel Nutritional Highlights

High Protein (52.8 g per 100 g): Supports strength, recovery, and daily energy.

Omega-3 (4.83 g per 100 g): Reduces inflammation, supports mobility, and promotes healthy skin & coat.

How to Use

Recommended Daily Serve

  • Ponies (Under 350kg): 2.5g (½ a teaspoon) per day.
  • Horses (Over 350kg): 5g (1 teaspoon) per day.

Loading Phase
For the first two weeks, we recommend a double dose to kickstart the benefits. You can easily split this across two daily feeds.

During Loading Phase

  • Ponies (Under 350kg): 5g (1 teaspoon a teaspoon) per day.
  • Horses (Over 350kg): 10g (2 teaspoons) per day.

The daily dose can be split across two feeds. Consistency over time delivers the best results — exact dosing does not need to be precise.

Research & Testing

At Marine Vitality, every batch of our Jervis Bay Mussel Powder is supported by independent analysis and industry recognised quality standards. Our approach is simple. If we claim it, we can verify it.

Independent Laboratory Analysis

Our mussels undergo detailed laboratory testing to confirm their nutrient profile, including protein levels, omega 3 composition and phospholipid content. This testing verifies the high levels of EPA, DHA and phospholipid bound omega 3s that set Jervis Bay Blue Mussels apart from standard mussel powders, including Green Lipped Mussel.

Phospholipid Bound Omega 3s

One of the most important findings in our research is the naturally high percentage of phospholipid bound omega 3s. Independent analysis shows that Jervis Bay Blue Mussels contain 68 percent phospholipid bound omega 3s, which supports superior absorption and more effective delivery of EPA and DHA.

Nutrient Density and Protein Quality

Testing also confirms the rich protein content and broad nutrient profile of our mussels. The protein is naturally complete and highly digestible, making it suitable for both dogs and cats as a daily nutritional support.

Comparative Analysis

Our mussels have been directly compared with standard mussel powders, including New Zealand Green Lipped Mussel. The findings show naturally higher levels of bioavailable omega 3s and a stronger overall nutrient density in Jervis Bay Blue Mussels. These differences reflect both species characteristics and the unique marine environment of Jervis Bay.

Sustainable, Local and Traceable

All mussels are produced in the pristine waters of Jervis Bay and processed under strict quality controls. Our production is zero waste, with both mussel meat and shell utilised. We work with accredited facilities that meet Australian food safety and aquaculture standards to ensure consistency and purity in every batch.

Ongoing Quality Assurance

We continue to work with researchers and industry partners to refine our data and maintain a high standard of product integrity. As more research becomes available, we will update our testing summaries so that customers always have clear and current information about what is in their pet’s bowl.

This commitment to transparency and ongoing testing is at the heart of Marine Vitality. We want you to feel confident that every serve of Jervis Bay Mussel Powder is grounded in real science and produced with care.

Certifications & Assurances

  • Processed in a NSW Food Authority approved human-grade facility.
  • Best Aquaculture Practices (BAP) certified
  • Responsible, sustainable farming.
  • Zero-waste production – every part of the mussel and oyster is put to use.

New to marine supplements?

Start small and build up gradually

If your horse is new to marine-based supplements, start with a smaller amount for the first few days and gradually build up to the recommended serve. This allows their digestive system to adjust while still introducing the benefits.

Days 1–3

Pinch only

Let them sniff and explore

Days 4–7

¼ dose

Mixed well into the feed

Week 2

½ dose

Most horses accept by now

Week 3+

A quick note

Jervis Bay Mussel Powder is a whole-food, single-ingredient supplement, not a concentrated extract. Consistency over time is more important than exact amounts.

Precautions

Not recommended for horses with known shellfish allergies, mares in foal, or mares with a foal at foot. Introduce any new supplement gradually and consult your vet if your horse has existing health conditions. This product is a complementary animal food and is not intended to diagnose, treat or cure disease.

We noticed Tito was limping on one of his back legs, and our vet recommended supplements. Luckily, we found this amazing brand! After using three containers, the improvement was incredible. Tito is now running around just like he used to, and seeing him happy and active again gives us such peace of mind. We’ve just received our second order, and I really wanted to share our experience so more families know that effective, affordable supplements are out there. We’re so grateful to have found this product. Seeing Tito enjoying life again means everything to us! ❤️🐾

We bought the traditional white shell mix and there was some improvement in the egg quality but you can tell the chicken weren’t keen. Swapped it out and you would think I had put a bowl of black sunflower seeds out. The eggs & hens have all levelled up! Great product.

Customer photo review of Marine Vitality Mussel Powder For Dogs - 150g

This is the 2nd time we have ordered this product. Our 4 legged fur baby Bear absolutely loves the taste. No trouble with eating it. Just mix with his night food. We thought at first it wasn't doing anything for him, but once 1st order finished and had to wait a few days for 2nd order, as we weren't going to re order, he started to go backwards with his walking. So it was definitely doing something for his hips and legs. Will keep him on it, as it is helping his traction on our floor boards at home also. Just loves life at the beach, when ever we get there on our holidays, as we love to travel with him. Bear is an English Staffy and over 13 years old now. Just wanted to give him a better quality of life in his old age. Highly recommend this product.

Frequently Asked Questions

What is Marine Vitality and what's in it?

Marine Vitality is 100% pure Australian blue mussel powder — nothing else. No fillers, no additives, no synthetics. The mussels are sustainably farmed in Jervis Bay, NSW, and gently processed to preserve their natural nutritional profile. Each serve delivers naturally occurring omega-3 fatty acids, glucosamine, chondroitin, high-quality marine protein and phospholipids.

Is this the same product you sell for dogs and cats?

Yes — it's the exact same 150g mussel powder. The active ingredient and nutritional profile are identical. We've created a separate horse page because the dosing, introduction schedule and feeding tips are different for equines, but the product itself is the same one trusted by dog and cat owners across Australia.

How is Australian blue mussel powder different from green-lipped mussel (GLM) powder?

Both are valued sources of marine nutrition, but Australian blue mussels have some distinct advantages. Independent analysis by the University of Newcastle found our Jervis Bay mussel powder delivers a higher total omega-3 content (4.83g per 100g vs 3.9–4.5g for NZ green-lipped mussels) and a higher phospholipid fraction (68% vs ~59%). Phospholipid-bound omega-3s are more readily absorbed by the body than free fatty acids, which means your horse gets more out of every serve. Our mussels are also farmed and processed entirely in Australia — no import lag and full traceability from sea to stable.

How long before I see results?

Most horse owners start to notice changes in comfort and movement within 3 to 6 weeks of reaching the full daily dose. Results vary depending on your horse's age, weight, existing joint condition and overall diet. The loading phase (double dose for the first two weeks) is designed to build up levels faster. Consistency is key — this is a whole-food supplement that works best as part of a daily routine.

My horse won't eat it. What should I do?

Marine Vitality has a natural seafood aroma — it's a sign of quality, but it can take some horses a few days to accept it. The most important thing is to go slowly. Start with just a pinch for the first few days and let your horse sniff and explore before eating. If they're still hesitant, try mixing the powder into something they love: a drizzle of molasses, linseed oil, grated apple or carrot, warm beet pulp mash, or soaked chaff all work well. Most horses accept it readily within the first week once they've had time to get used to the smell.

Can I give it to my pony?

Yes. The dose is adjusted for body weight. Ponies under 350kg should receive 2.5g (half a teaspoon) per day, with a double dose for the first two weeks as a loading phase. The same gradual introduction schedule applies.

Can I split the dose across two feeds?

Yes — this is fine and can make introduction easier for fussy horses. Simply divide the daily amount across your morning and evening feeds.

Is it safe for performance or competition horses?

Marine Vitality contains only 100% pure mussel powder with no added substances. It is a natural, whole-food supplement. However, if your horse competes under rules that require feed declarations or restrict certain substances, we recommend checking with your relevant equestrian body or vet before use, as requirements vary between sports and jurisdictions.

Are there any horses it's not suitable for?

Marine Vitality is not recommended for horses with a known shellfish or seafood allergy. It is also not recommended for mares in foal or mares with a foal at foot. If your horse has existing health conditions or is on veterinary medication, consult your vet before introducing any new supplement.

How should I store it?

Store in a cool, dry place away from direct sunlight. Keep the lid tightly closed after each use to maintain freshness. Shelf life is 2 years from production.

How long does one pack last?

A 150g pack will last approximately 30 days for a standard horse (over 350kg) on a full daily dose of 5g. For ponies on 2.5g per day, a pack will last approximately 60 days. During the two-week loading phase at double dose, a pack will last approximately 15 days for a full-sized horse.

Product & Nutrition

What is Jervis Bay Mussel Powder?

Jervis Bay Mussel Powder is a single-ingredient, whole-food supplement made from 100% Australian blue mussel meat. It provides naturally occurring omega-3 fatty acids, phospholipids, protein and marine amino acids to support overall wellbeing as part of a balanced diet.

What type of mussels do you use?

We use Australian blue mussels sustainably grown in Jervis Bay, NSW. Our mussels are grown, harvested and processed locally, giving us full traceability from sea to bowl.

Why do you use Australian blue mussels instead of green-lipped mussels?

Australian blue mussels are a highly nutritious marine food, naturally rich in omega-3s, phospholipids, protein and marine amino acids.

Independent research has shown Australian blue mussels to be comparable, and in some areas nutritionally superior to green-lipped mussels, particularly in phospholipid content, which supports bioavailability. Local sourcing also allows greater control over freshness and quality.

Is this an extract or a whole food?

Jervis Bay Mussel Powder is a whole-food powder, not an extract. The mussels are gently processed and milled without isolating or concentrating individual compounds. Nutrients remain in their natural food matrix, supporting gentle digestion and long-term use.

What does bioavailability mean in a whole-food supplement?

Bioavailability refers to how easily nutrients are absorbed and used by the body. In whole marine foods like mussels, omega-3s are naturally bound to phospholipids, which can support absorption compared to isolated oils. This makes whole-food marine nutrition a food-first option for everyday use.

Is this a complete food?

No. Jervis Bay Mussel Powder is a supplementary whole food designed to be added to your pet’s existing diet. It does not replace complete pet food.

Can I use this alongside raw, home-cooked or premium pet food?

Yes. Jervis Bay Mussel Powder is designed to complement a wide range of feeding styles, including raw, home-cooked, fresh and premium commercial diets.

Are there additives, fillers or preservatives?

No. The product contains one ingredient only: whole Australian blue mussel meat.

Are there heavy metals or contaminants?

Our mussels are grown in the clean, nutrient-rich waters of Jervis Bay and produced in accordance with Australian food safety standards. Independent testing has shown levels to be within safe limits.

Why don’t you list exact nutrient amounts like some supplements?

As a whole-food product, nutrient levels can naturally vary between harvests and seasons. Rather than isolating or standardising individual compounds, we focus on consistent quality, sourcing and processing so nutrients remain in their natural food form.

Why does your zero-waste approach matter?

Our zero-waste aquaculture model means every part of the mussel harvest is valued and utilised. This supports sustainability while allowing us to maintain freshness, reduce unnecessary processing and keep full control over quality.

How should I store it?

Store in a cool, dry place with the lid tightly sealed to maintain freshness
