Arthritis is a bone condition where there is a breakdown of the cartilage in the joints. Cartilage is important for the smooth movement of joints. So it is once it starts breaking down that you find it difficult bending, walking and even doing simple, everyday things like getting up from the bed.
This is when arthritis pain starts in joints like legs and hips. It can occur in both humans and most animals, including dogs. And a common treatment option for arthritis in humans and dogs is prescribing joint supplements containing ingredients like glucosamine.
Before we get into the explanation, we would like to recommend that you take a moment to check out our favourite and highest rated option when it comes to glucosamine for dogs. That is Nutrimax Dasquin (click below)

What is glucosamine?
Glucosamine is basically a natural cartilage building block which is used by the body much faster than it’s produced as the body ages. Glucosamine products help replenish these depleting glucosamine levels and in the process, provide some relief from arthritis symptoms.
With both humans and dogs finding relief from arthritis through the same supplements, many wonder if it’s safe to give human glucosamine to dogs and if there is any major difference between the two.
Well, the answer to this question is that while it’s safe to give human glucosamine to dogs, there are these major differences between the two.
- Two types of glucosamine
The first thing to know is that there are two types of glucosamine used in joint aide products- glucosamine sulphate and glucosamine hydrochloride. While both types are available at any health store, it’s general products containing glucosamine hydrochloride that are better for your dog as they are more readily absorbed by them.
- Varied composition
Different aide products have different compositions where the human supplements are generally made using 99% strength glucosamine hydrochloride. On the contrary, dog specific supplements contain 90% strength glucosamine.
However, if you compare the working between the two, the dog formulas are designed to give the quickest relief from pain. This is because most of the substance is directly absorbed into the dog’s system.
- Difference in regulation
Human and dog glucosamine have different regulations. The dog options are generally highly regulated while the human versions are considered more of a dietary aide. This is why they are not regulated by the FDA. So by choosing and giving your dog a dog specific product, you know it’s regulated and know what you are giving your dog.
- Price difference
There is a huge difference between the two types of products where the ones meant for dogs are more expensive than the human varieties. This may be attributed to the fact that the dog supplements are FDA regulated.
However, it is not necessary that the most expensive one is always the best. It’s always better to compare the ingredients between different products to ensure you are paying a worthy rate.
- Food safety
While the human grade variety is safe to give your dog, those labelled ‘pet food’ or ‘pet grade food’ may contain some ingredients that are not FDA approved or rendered safe by the Meat Inspection Act or Pure Food and Drug Act for human consumption.
This is because many of the pet/animal varieties and foods contain animal products that are not legal or safe for people. On the contrary, dogs and other animals can anytime safely eat human food products.
- Food composition
The human grade glucosamine products are usually of a higher quality, and a purer form. Besides, the concentration also differs between different products. The products meant for dogs contain ascorbic acid or manganese, essential for the absorption of glucosamine in the dog.
In addition to this, the dog varieties may be fortified or flavoured with other minerals for your dog’s betterment, and also to make it more palatable to the dog. This is why you have bacon and cheese flavoured products to make them more appetizing to dogs.
So the benefit of giving your dog supplements meant for them is that you know they contain helpful and integral compounds. You also know that they come with the perfect dosage for your dog.
On the contrary, it is the other ingredients in the human varieties which may make a supplement unsafe for your dog. There are in fact some ingredients in some human options like chocolate and xylitol that are fatal to your dog.
- Different forms
There is another major difference between a pet and human joint aide product which is its form. The human varieties are meant to be swallowed and dissolved in the human digestive tract. However dogs have a shorter digestive tract than humans, so this means the ingredients have to be absorbed by the body before passing out through the body.
Dog types are generally chewable so that it’s easily broken up to be quickly absorbed. Human types, however, can end up just passing through the dog, without getting absorbed.
So looking at all these differences, you should know by now that the main differences between human and dog glucosamine are its form and dosage. Tablets that are not designed for dogs may not be useful for their joint problem as they will not get absorbed by the dog’s digestive tract.
Besides, there is a difference in the way dogs metabolize some vitamins and minerals when compared to humans. This is why though it’s tempting to give the same human glucosamine you take to your dog, it’s better to find a supplement that’s safe for your pet and has the appropriate dosage guidelines.
You should never give your dog the supplement based on your human dosage as humans and dogs have different glucosamine needs, requirements and dosages.
