Frequently asked questions

When does my dog need a glucosamine joint formula?

What are the signs of arthritis in dogs?

Dog slow to rise from a resting position
Dog reluctant to climb steps
Dog tires easily or lags behind on walks
Dog appears stiff or even limp after activity

Why is RJX a recommended glucosamine joint supplement for dogs?
RJX provides therapeutic levels of three of the most studied nutrients for joint health: glucosamine, chondroitin, and MSMS. Additionally it provides a special form of manganese, which is a critical mineral in support of joint health. In liquid form the product is easy to use and provides a great value.

RJX glucosamine formula for dogs is manufactured under the highest GMP standards, and, with Nusentia's 60 day 100% money back guarantee, you can rest assured that you've made the right choice for your dog.

Will my dog like the liquid/flavor?
Our experience is that dogs do love the flavor of the glucosamine liquid as the product is specifically designed with dogs in mind. An added benefit is pet owners love the convenience!

If my dog is on anti-inflammatory drugs can I use RJX glucosamine supplement with them?
Yes. Often the two treatments are combined. Since medications have side effects the ultimate goal is to reduce the medications or eliminate them entirely as your pet improves.

Can I give RJX to my puppy or young dog?
Yes. But you may want to consider using Spectrin for Dogs instead to use as foundational nutrition with glucosamine and other joint support ingredients. Younger dogs who are not yet facing joint tissue degradation do not require the high levels of glucosamine, chondroitin, and MSM that is offered in RJX. If you do use RJX for your puppy or young dog follow the instructions on the bottle, which are based on body weight.

I put RJX in the refrigerator and crystals formed. Is this normal and can I still use it?
Because RJX is so concentrated, The MSM crystalizes under very low temperatures. Storing RJX at room temperature usually solves the issue. If crystals form, this will not cause a problem with efficacy, however, you may need to heat the product or raise the temperature before dosing to get the MSM back into the solution. Usually, setting the solution in warm water for some time works best without overheating the product.
