Quick answer: Johnson's 4Joints Turmeric Granules are 32% oat cereals, 25% beet pulp, 25% hemp seed meal, 5% turmeric powder, 5% grassmeal, 2.5% sunflower oil and 0.6% curcumin, with added vitamins C and E, omega-3, piperine, magnesium and calcium. By our sums from the published label, a 10g scoop holds about 60mg curcumin and 50mg omega-3. There's no glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid or Boswellia. If you want those, we'd recommend MedPaw Hip & Joint Chews instead: all six key joint actives in a soft chew, with the main amounts per chew on the label.
Transparency note: this page is written by MedPaw, which makes a competing joint supplement. The 4Joints composition comes from UK retailer and wholesaler listings, because we couldn't reach Johnson's own website. Amounts per scoop are our own arithmetic from the published percentages and amounts per kilo. Everything was checked on 8 October 2026.

Sources: composition from Jollyes; amounts per kilo from petproducts.co.uk; 10g scoop from Discount Pet Superstore. Checked 8 October 2026.
Analytical constituents, as listed by Jollyes: crude protein 12%, fat 8%, crude fibre 15% and crude ash 7%. The high fibre figure fits a recipe that's mostly oats, beet pulp and hemp seed meal.
What each ingredient is there for
- Oats, beet pulp and grassmeal: plant base ingredients that make up most of the granule. They add fibre and bulk rather than any joint active.
- Hemp seed meal: ground hemp seed, a source of protein, fibre and plant fats. It isn't the same thing as CBD oil.
- Turmeric and curcumin: curcumin is the main active compound in turmeric. Retailer descriptions call it a natural antioxidant.
- Piperine: black pepper extract, included, according to retailer descriptions, to help absorption.
- Omega-3: the label doesn't say which type. No fish oil, krill or mussel is listed, and the only oils are hemp seed and sunflower.
- Vitamins C and E: antioxidant vitamins, at 5mg and 10mg per scoop.
How many scoops a day?
We couldn't find out. The retailer listings we read say a 10g scoop is included but don't give the number of scoops by weight, and Viovet says only that it's for daily use, mixed with normal food. So we can't say how much curcumin or omega-3 your dog would get in a day. Follow the guide on the bag.
Allergens
We didn't find an allergen statement in the listings we read. The composition includes oats and hemp seed, and doesn't list chicken, fish, shellfish or egg. That's one area where the granules may suit some dogs better than MedPaw, which contains mollusc (green-lipped mussel) and gluten (brewer's yeast). If your dog has a food allergy, check the bag and ask your vet.
What the evidence says
A 2022 meta-analysis of 72 trials by Barbeau-Grégoire et al. (International Journal of Molecular Sciences) looked at supplements for arthritis pain in dogs and cats:
- Curcumin (turmeric): five studies with mixed results: one negative, two unclear and two positive. Promising for some, but not settled.
- Omega-3: the strongest evidence of any supplement for arthritis pain. The research mostly used fish oil, which 4Joints granules don't list, and 50mg a scoop is a small amount. See our fish oil dose guide.
- Glucosamine and chondroitin: the review found they didn't relieve pain. That applies to MedPaw's glucosamine and chondroitin too. They're widely used to support cartilage, but don't expect them to act as a painkiller.
- MSM, Boswellia and hyaluronic acid: too few studies to judge on their own.

What's missing compared with MedPaw
4Joints granules are built around turmeric. MedPaw is built around the six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia, plus vitamins C and E and zinc. The granules contain none of the six. MedPaw has no turmeric.
Why 4Joints customers switch to MedPaw
4Joints Turmeric Granules vs MedPaw: what's in each
| The issue | 4Joints Turmeric Granules | MedPaw (per chew) |
|---|---|---|
| Key joint actives | None of the six | All 6: MSM 185mg, glucosamine 170mg, chondroitin 70mg, green-lipped mussel 70mg, Boswellia 30mg, plus hyaluronic acid |
| Main ingredients | Oats, beet pulp and hemp seed meal (82%) | Joint actives in a soft chew |
| How much to give | No guide by weight in the listings we read | 1 chew up to 4kg, 2 for 5 to 17kg, 2 to 3 for 18kg and over |
| Format | Granules mixed into food | Soft chicken and bacon chew, given like a treat |
| If it doesn't suit | No guarantee we could find; retailer returns policy applies | 60-day money-back guarantee, nothing to send back |
Our recommendation: if you've read the 4Joints label and want a supplement with the established joint actives rather than a turmeric granule, choose MedPaw, unless your dog has a shellfish or gluten allergy. Swap rather than stack, give it six to eight weeks, and if you're not happy, email bark@medpaw.co.uk within 60 days of delivery for a refund. 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 is in Johnson's 4Joints Turmeric Granules?
Oat cereals 32%, micronised beet pulp 25%, hemp seed meal 25%, turmeric powder 5%, grassmeal 5%, sunflower oil 2.5% and curcumin 0.6%, plus vitamin E, vitamin C, omega-3, piperine, magnesium and calcium.
How much curcumin is in 4Joints granules?
The label lists curcumin at 0.6%, which is about 60mg in a 10g scoop, alongside 5% turmeric powder (about 500mg). How much your dog gets a day depends on the number of scoops, which the listings we read don't give by weight.
Do 4Joints granules contain glucosamine or green-lipped mussel?
No. The granules don't list glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid or Boswellia. MedPaw contains all six.
Does 4Joints contain fish oil?
No fish oil is listed. The label gives omega-3 at 5,000mg per kilo (about 50mg per 10g scoop) without saying which type, and the only oils listed are hemp seed and sunflower.
Is 4Joints or MedPaw better for joints?
They're different kinds of product. 4Joints granules are a turmeric and curcumin supplement in an oat and hemp base. MedPaw has all six key joint actives with the main amounts per chew on the label and a 60-day guarantee, which is why we'd recommend it for most dogs.
Can I switch from 4Joints to MedPaw straight away?
Yes. Stop the granules 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.
