Quick answer: Nutripaw Hip & Joint Treats Plus is mostly chickpea flour, potato starch and glycerine, with salmon oil (8%), other fish oil (4%), fish collagen (2%), magnesium (0.4%) and hyaluronic acid (0.08%). Its headline ingredient, KynoSil (a silicon ingredient), has no amount given, and nor do the EPA and DHA from its fish oil. It contains no glucosamine, chondroitin, MSM, green-lipped mussel or Boswellia. If you want those, with the main amounts per chew on the label, we'd recommend trying MedPaw Hip & Joint Chews instead: all six key joint actives in a soft chicken and bacon chew, with a 60-day money-back guarantee and nothing to send back.
Transparency note: this page is written by MedPaw, which makes a competing joint supplement. Nutripaw's composition is quoted word for word from its own product page, and the evidence comes from a published review linked below. Everything was checked on 8 October 2026.
Nutripaw Hip & Joint Treats Plus: full composition
This is the composition as published on Nutripaw's Hip & Joint Treats Plus page, in label order:
"Products from the processing of plants (Chickpea Flour), Starch (Potato), Glycerine, Fish Oil (Salmon); 8%, Yeasts, inactivated (Saccharomyces cerevisiae), Fish Oil (Various Fish); 4%, Collagen (Fish); 2%, Crude Lecithins (Sunflower Lecithin), Processed Animal Protein, Magnesium (Magnesium chelate); 0.4%, Hyaluronic Acid; 0.08%, Disodium Dihydrogen Diphosphate, Sodium Chloride."
There's no separate additives section and no analytical constituents (protein, fat, fibre, ash or moisture) on the page. It's sold as a chew or "daily treat"; the page doesn't describe it as a complementary feed. Each tub holds 120 chews.
The key ingredients, per chew
Nutripaw Hip & Joint Treats Plus: what's published for each key ingredient
| Ingredient | Amount per chew | What Nutripaw publishes |
|---|---|---|
| KynoSil (bioactive silicium) | Not published | Named as the headline ingredient; not shown by name in the composition |
| Salmon oil | Not published | 8% of the chew |
| Other fish oil | Not published | 4% of the chew |
| EPA and DHA (omega-3) | Not published | Named, no amount |
| Fish collagen | Not published | 2% of the chew |
| Magnesium (chelate) | Not published | 0.4% of the chew |
| Hyaluronic acid | Not published | 0.08% of the chew |
| L-lysine, decaf green tea extract, trace minerals | Not published | Named on the page, not shown by name in the composition |
| Glucosamine, chondroitin, MSM, green-lipped mussel, Boswellia | None | Not in the composition |
Because Nutripaw doesn't publish the weight of a chew, you can't turn those percentages into milligrams from the product page. That makes it hard to compare with other joint supplements, or to know whether the fish oil reaches a useful omega-3 dose.
Nutripaw's older product, the original Hip & Joint Treats, is a different formula. A retailer listing gives its actives as "Glucosamine, MSM, Turmeric, Chondroitin, Algae, Salmon Oil, Vitamin C, Devil's Claw Root, Black Pepper, Vitamin E", without amounts (Buy4PetsOnline). The Plus is the joint chew Nutripaw now promotes on its own site.
Allergens
The Plus contains fish (salmon oil, other fish oil and fish collagen), inactivated yeast, chickpea flour and an unspecified "processed animal protein". There's no allergen statement on the page, which describes the chew as "hypoallergenic". Nutripaw's FAQ says its products have "no corn, no preservatives, no wheat, no GMO, and no soy." For comparison, MedPaw contains mollusc (green-lipped mussel) and gluten (brewer's yeast), so it isn't suitable for dogs with a shellfish allergy.
What the evidence says
A 2022 systematic review and meta-analysis of 72 trials in dogs and cats with osteoarthritis (Barbeau-Grégoire et al., Int J Mol Sci) found:
- Omega-3 (fish oil): the strongest evidence of pain relief in the review. This is Nutripaw's best-supported ingredient, but without published EPA and DHA amounts you can't tell whether a chew provides a meaningful dose.
- Collagen: weak evidence. The authors said it was impossible, for now, to rule on a use for collagen in canine osteoarthritis.
- Glucosamine and chondroitin: didn't relieve pain in that review. MedPaw contains both, and we'd rather you heard that from us.
- Hyaluronic acid and MSM: only studied as part of combination products, where the authors said more high-quality studies are needed.
- Silicon (KynoSil): we couldn't find it in the review's results. Nutripaw's page says KynoSil is "clinically studied in humans and animals" but doesn't link to a study.
In short: no joint chew, ours included, should be sold as a painkiller. If your vet recommends omega-3, a dedicated fish oil with a stated EPA and DHA dose is the most reliable way to give it.
What's missing compared with MedPaw
Why Nutripaw customers switch to MedPaw
| The issue | Nutripaw Plus | MedPaw |
|---|---|---|
| Amounts per chew | Not published; percentages for some ingredients | The main amounts per chew on the label |
| Glucosamine | None | 170mg per chew |
| Chondroitin | None | 70mg per chew |
| MSM | None | 185mg per chew |
| Green-lipped mussel | None | 70mg per chew |
| Boswellia | None | 30mg per chew |

Our recommendation: if you want a joint chew with all six key joint actives and the main amounts on the label, rather than percentages and unstated amounts, switch to MedPaw. Swap rather than stack: stop Nutripaw and start MedPaw the next day. Give it six to eight weeks, and if you're not happy, email us within 60 days and we'll refund you. Try MedPaw Hip & Joint Chews.
If nothing has worked so far
If your dog is still stiff or sore after a fair trial of any supplement, see your vet. They may suggest pain relief, weight loss or an omega-3 fish oil at a proper dose, which has the strongest evidence for dogs with arthritis. Read what you can safely give a dog for joint pain and the best fish oil for dogs' joints.

What's in Nutripaw Hip & Joint Treats Plus?
Chickpea flour, potato starch, glycerine, salmon oil (8%), inactivated yeast, other fish oil (4%), fish collagen (2%), sunflower lecithin, processed animal protein, magnesium chelate (0.4%), hyaluronic acid (0.08%), disodium dihydrogen diphosphate and salt. Nutripaw also names KynoSil, EPA and DHA, L-lysine, green tea extract and trace minerals, without amounts.
Does Nutripaw contain glucosamine?
The current Hip & Joint Treats Plus doesn't: glucosamine isn't in its published composition. The older Hip & Joint Treats listed glucosamine, chondroitin and MSM.
What is KynoSil?
Nutripaw describes it as a highly bioavailable form of silicium (silicon). It doesn't say how much is in a chew, and it doesn't link to a study on its product page.
Is Nutripaw a fish oil supplement?
It contains salmon oil and other fish oil, but Nutripaw doesn't publish the EPA and DHA per chew, so you can't tell how it compares with a dedicated fish oil.
Does Nutripaw contain any allergens?
It contains fish, yeast, chickpea and an unspecified processed animal protein. There's no allergen statement on the product page. MedPaw contains mollusc and gluten, so check whichever you choose against your dog's allergies.
Can I switch from Nutripaw to MedPaw straight away?
Yes. Stop Nutripaw and start MedPaw the next day. There's no need for a gap, and you shouldn't give both. Check with your vet first if your dog takes any medication.
