DOG FIT by PreThis® JOINTS greenshell
DOG FIT by PreThis® JOINTS greenshell
Pure Green-Lipped Mussel + Collagen for joint care.
The original from sustainable New Zealand farming.
DOG FIT by PreThis® JOINTS greenshell is a natural joint support. It combines high-quality Green-Lipped Mussel (from sustainable farming) with essential collagen as well as important B vitamins (B6, B9, B12) and Vitamin E. These micronutrients sensibly supplement the daily diet and contribute to supporting the normal function of joints, cartilage structures, and nerves. Furthermore, the complex can support the physiological production of synovial fluid (joint fluid) – an important contribution to the natural lubrication of joint surfaces.
The natural Glycosaminoglycans (GAGs) from the green-lipped mussel are considered a building block of synovial fluid, which is required for the low-friction interaction of joint surfaces. The combination is particularly suitable as a complementary feed for dogs with an increased need for joint-supporting nutrients – such as with breed-specific challenges (like in German Shepherds, Labradors, or French Bulldogs) or in life stages with increased demands on the musculoskeletal system, such as growth, old age, or intense physical activity of the dog. Link to a scientific study.

Good quality
Long search and found :-) Very well dosed because 1:5 extract, you won't find that anywhere else. So the price is absolutely right - with others you get a lukewarm powder with no effect. Top!

Good supplement for the food
Dear team, our dog (15) has been getting it as a prophylactic in his food for 4 years now, so it's time to evaluate it :-) He tolerates it very well and is still fit and happy today. I am sure that Greenshell and the immune system contribute to this. I have been advised by Arne and Sandra several times in the meantime and have been very satisfied every time. You guys are great, keep it up!

Patellar luxation
The vet wanted to operate immediately but that was out of the question for me and I looked around for alternatives until I ended up here. The advice is of a high standard. The advice to give green-lipped mussel together with joints brought success without painkillers and surgery. Now I am a regular customer.

Top in combination!
Our old dog has really bad osteoarthritis. We started with Joints with glucosamine and that had already helped. Sandra from the store then gave me the tip to combine it with Joints green-lipped mussel. That did the trick! Our old guy is now doing quite well again. Thank you dear Dog Fit team.

The best product I know. My 12 year old German shepherd is doing really well again.
Nothing worked, nothing helped. Injections only worked for a short time. The consultation was unique, I was offered a voucher and I'm thrilled. It could hardly be quicker, more reliable and more enjoyable. Your loyal Claudi

Since our dog has been given this medicine, he no longer has any problems with his joints. I can only recommend this medicine.

I am very satisfied, my dog...
I am very satisfied, my dog (Laprador) was diagnosed with a patellar luxation at 5 months since I have been giving her a capsule every day, she hardly limps any more. She will not be able to avoid an operation, but since she has been putting weight on her leg since taking the capsules, important muscle tissue has been built up and all this without painkillers.

Questions
Which dogs is JOINTS greenshell intended for?
For adult dogs of any size and breed. We especially have in mind dogs whose musculoskeletal system is under greater everyday load, and for owners who also want to rely on green-lipped mussel. JOINTS greenshell is a complementary feed for daily feeding and no substitute for a balanced diet. If your bitch is pregnant or nursing, or your dog is currently under veterinary treatment, please discuss supplementary feeding with your veterinary practice first. You will find the right size for your dog's weight under “Dosage instructions”.
Is JOINTS greenshell well tolerated?
JOINTS greenshell is generally very well tolerated – we select our ingredients for high quality and a natural composition. As with any natural product, an individual dog may still react sensitively to a single ingredient. If you notice signs of intolerance, pause the supplement and get in touch with us – we are happy to help. If your dog has pre-existing conditions or receives a special diet or medication, please also talk to your veterinary practice.
When can I expect to see first results?
This varies from dog to dog and depends on your dog's individual needs. As a rule, feed JOINTS greenshell for at least six weeks, in some cases longer. Natural formulations need time to unfold their supporting properties – regular feeding matters more than a high single dose.
How long does one pack of JOINTS greenshell last?
One pack contains 60 capsules and therefore lasts around two months with daily feeding. If your dog receives an extra capsule according to the dosage recommendation, it will last correspondingly less. For continuous feeding we offer value packs.
My dog won't eat the capsule – what can I do?
That can almost always be solved. Many dogs accept the capsule more readily when it is embedded in something soft – a spoonful of wet food, quark or a piece of liver sausage usually does the trick. If your dog doesn't like the capsule at all, you can also open it and mix the contents into the food. One note on this: with JOINTS greenshell the capsule shell is made of high-quality collagen (beef) and is therefore a valuable component in itself. So don't throw it away after opening – soften it briefly in a little water and add it to the food. What matters most is regularity: an occasionally missed dose is no problem, but feeding should not be interrupted for long.
What makes JOINTS greenshell special?
DOG FIT by PreThis® JOINTS greenshell stands for premium quality green-lipped mussels from sustainable farming in New Zealand. This special preparation is aimed at supporting the synthesis of synovial fluid and helps reduce wear and tear on the joints. The high-quality ingredients of the green-lipped mussel enable a natural and effective promotion of joint health in dogs. JOINTS greenshell is the ideal choice for dog owners who value natural, sustainable solutions to maintain the mobility and vitality of their four-legged friend.
Can I also give JOINTS greenshell preventively?
Yes, a prophylactic use of DOG FIT by PreThis® JOINTS greenshell makes a lot of sense. By integrating it into a dog's diet at an early stage, this supplement can help maintain long-term joint health and functionality. JOINTS greenshell offers valuable support, especially for dogs whose joints are under particular strain due to their breed, age or lifestyle.
The natural ingredients contained in the green-lipped mussel can promote the production of synovial fluid and thus support the joints in the long term. Regular supplementary feeding can help maintain dogs' mobility and joy of life.

Great products
Thanks to the VITAMIN B complex, my dog has become much more balanced and calm in stressful situations. And the JOINTS greenshell combination set has really shown us the difference: when it was sold out for two months, my dog often rested his hind leg and was much less active. Since the combination pack has been back in stock, his enjoyment of exercise has improved significantly within just a few days! The hard coating on his teeth has also become much softer – the natural cleaning effect works great. A clear recommendation!
