Nutramax Supplements Explained: Cosequin, Dasuquin, Denamarin and Denosyl
Nutramax produces several of the best-known veterinary supplement brands, but similar names can make the range confusing. Cosequin and Dasuquin support joints; Denosyl and Denamarin support the liver. Choosing between them starts with understanding what each formula adds.
What is Nutramax?
Nutramax Laboratories develops supplements for joint, liver, digestive and general pet health. The company states that its products undergo extensive quality checks for contaminants, ingredient identity and label accuracy.
The products discussed here are supportive supplements. A limping dog or a pet with abnormal liver results still needs veterinary diagnosis and an individual care plan.
What is Cosequin?
Cosequin is a joint-health supplement built around glucosamine hydrochloride and chondroitin sulphate. Some formulas also include MSM. These ingredients support cartilage structure, joint function and comfortable mobility.
Cosequin is commonly chosen for:
- age-related stiffness;
- everyday cartilage support;
- active or working dogs; and
- long-term mobility maintenance.
Cat-specific Cosequin products are also available. Always choose a formula labelled for the correct species and weight.
What is Dasuquin?
Dasuquin is Nutramax’s premium joint range. It combines glucosamine and chondroitin with ASU—avocado/soybean unsaponifiables. Some products add MSM and other supporting ingredients.
The ASU combination is intended to provide broader cartilage support, which is why Dasuquin is often considered when joint concerns are more established or when a vet recommends a more comprehensive formula.
Cosequin vs Dasuquin: what is the difference?
Both ranges support joint health, but their formulations and price points differ:
- Cosequin: glucosamine and chondroitin form the core, with MSM in selected products.
- Dasuquin: builds on glucosamine and chondroitin by adding ASU, with further ingredients in some versions.
Cosequin may suit routine or earlier-stage support, while Dasuquin is often chosen for more advanced needs. This is not a diagnostic rule—your vet can recommend the most appropriate formula for your pet.
How long do joint supplements take to work?
Joint supplements are not instant painkillers. Many pets require several weeks of consistent use before owners notice a meaningful difference. Products may begin with a higher loading amount before moving to a maintenance dose, so follow the label carefully.
Weight control, suitable exercise, pain management and home adaptations can be just as important as supplementation for an arthritic pet.
What is Denosyl?
Denosyl supplies SAMe, or S-adenosylmethionine. SAMe is a naturally occurring compound involved in antioxidant production and normal liver-cell function. Nutramax uses a stabilised, enteric-coated tablet to protect the ingredient before absorption.
What is Denamarin?
Denamarin combines SAMe with silybin, a concentrated and absorbable component of milk thistle. This gives it two complementary components for liver support: SAMe for glutathione and cellular processes, and silybin for additional antioxidant support.
Denamarin vs Denosyl: which should I choose?
The central difference is straightforward:
- Denosyl contains SAMe.
- Denamarin contains SAMe plus silybin.
A vet may select one based on blood results, diagnosis, other medication and the level of support required. Do not use a supplement to self-treat jaundice, vomiting, appetite loss or abnormal liver tests.
How should liver supplements be given?
SAMe products are generally given on an empty stomach for reliable absorption, often around an hour before food. Enteric-coated tablets should usually be swallowed whole rather than crushed. Follow the exact product label or your vet’s instructions, because formulations can differ.
Can joint and liver supplements be used together?
They target different systems and may often be used together, but your vet should review the complete routine—especially when a pet has a diagnosed condition or takes prescription medication.

Choose by health goal, not brand name alone
Cosequin and Dasuquin belong to the joint-support side of the Nutramax range; Denosyl and Denamarin belong to liver support. Once that distinction is clear, your vet can help you select the exact product, strength and schedule that fit your pet.
