Not all pet supplements are created equal. The market is crowded with products that bury active ingredients in fillers, use low-quality sourcing, or make claims that don't hold up to scrutiny. KRWN takes a different approach: a small, focused range of supplements built around clean sourcing, minimal processing, and ingredients with genuine scientific backing.

We carry three KRWN supplements at Šapice Pet Wellness — each addressing a specific and common nutritional gap in modern pet diets. Here's what they are, what they do, and who they're for.

KRWN Green Lipped Mussel Powder

Green lipped mussel (Perna canaliculus) is one of the most comprehensively studied natural joint supplements available for pets. Sourced from the pristine, cold waters of New Zealand — where the mussels are sustainably farmed under strict environmental standards — it provides a uniquely broad spectrum of bioactive compounds that fish oil and standard glucosamine supplements simply can't match.

What makes green lipped mussel exceptional is its combination of omega-3 fatty acids (including ETA — eicosatetraenoic acid — which is not found in fish oil), glycosaminoglycans (the building blocks of cartilage), and a range of anti-inflammatory compounds that work synergistically. The result is a supplement that addresses joint inflammation, supports cartilage integrity, and promotes mobility — all from a single whole-food ingredient.

KRWN freeze-dries their green lipped mussel to preserve maximum potency — a critical distinction, as heat processing destroys many of the bioactive compounds that make GLM effective.

The KRWN Green Lipped Mussel Powder is suitable for both dogs and cats, and fine enough to blend invisibly into wet food. It's particularly well suited to:

Senior pets showing signs of stiffness or reduced mobility

Active or working dogs with high joint load

Large and giant breeds are prone to hip and elbow dysplasia

Cats over 7 years old (feline osteoarthritis is significantly underdiagnosed)

Any pet can benefit from a preventive supplement before joint issues develop

KRWN Atlantic Salmon Oil

Omega-3 fatty acids are the most evidence-backed supplement category in veterinary nutrition. EPA and DHA — the long-chain omega-3s found in marine sources — support skin and coat health, reduce systemic inflammation, support kidney and heart function, and have documented cognitive benefits in senior pets. Most commercial pet food is significantly deficient in omega-3s relative to omega-6s, making supplementation genuinely valuable for the majority of pets.

The quality of salmon oil varies enormously. KRWN Atlantic Salmon Oil is wild-caught and minimally processed to preserve the natural nutrient profile — a meaningful distinction from farmed salmon oil, which has a less favourable fatty acid ratio, and from heavily refined oils that lose potency during processing.

The KRWN Atlantic Salmon Oil is a daily liquid supplement that can be added directly to food. It's suitable for dogs and cats of all ages and is particularly beneficial for:

Pets with dry, flaky, or dull coats

Dogs and cats with skin sensitivities or allergies

Senior pets for cognitive and cardiovascular support

Pets on dry food diets, which are typically very low in omega-3s

KRWN Joint Care

While the green lipped mussel powder addresses joint health through whole-food nutrition, KRWN Joint Care is a targeted formulation designed for pets already experiencing joint discomfort or those at elevated risk. It combines glucosamine, chondroitin, and complementary compounds in a formulation designed to support cartilage repair, reduce inflammation, and improve mobility in pets with existing joint issues.

The KRWN Joint Care supplement is particularly well suited to:

Senior dogs and cats with diagnosed osteoarthritis

Dogs recovering from orthopedic surgery or injury

Large breeds with a genetic predisposition to joint disease

Active dogs that need additional joint support beyond baseline nutrition

For many pets, KRWN Joint Care and KRWN Green Lipped Mussel Powder work well together — the GLM powder provides broad-spectrum anti-inflammatory support and whole-food nutrition, while Joint Care delivers targeted glucosamine and chondroitin at therapeutic levels.

Why KRWN?

What distinguishes KRWN from the broader supplement market is the combination of clean sourcing, minimal processing, and a focused product range. Rather than offering dozens of products with diluted formulations, KRWN has built three supplements that do specific things well. The New Zealand sourcing for the green lipped mussel, the wild-caught standard for the salmon oil, and the targeted formulation of the joint care supplement reflect a brand that prioritises efficacy over marketing.

These are supplements we're confident recommending because the ingredient quality justifies the price point — and because the science behind each active ingredient is solid.
