What is Hyaluronic Acid (HA) and what is its function?
Hyaluronic Acid is a naturally occurring compound found in the joints and connective tissue of all mammals. HA acts as the lubricant for joints–kind of like liquid ball bearings. Hyaluronic Acid has been introduced directly into the knee joints of humans and horses for many years, yielding excellent benefits.

Why does my pet need a hyaluronic acid product?
Hyaluronic Acid is naturally produced by the body as a constituent of synovial fluid that lubricates the cartilage between the joints. As your pet ages, their body produces less and less HA and it becomes more and more difficult to replenish it and the cartilage and other structures of the joint begin to need support. Joints become less flexible and movement is limited. HA supplements pick up where their bodies fail them.

What does HA do for my pet’s joints?
The HA in HyaFlex™ helps to improve joint movement and cushioning. If we compare the joints of your pet’s body to an automobile engine, the joint fluid in their body mimics the oil in a car engine. At regular intervals we replace the oil in our car engines because the heat and friction breakdown the oil’s viscosity. The oil becomes thinner and less able to protect the metal surfaces from excessive wear. HyaFlex™ acts the same way in their joints. As your pet ages, the viscosity of their joint fluid breaks down and becomes thin and is unable to cushion the joint cartilage. This leads to increased friction on the cartilage surfaces of their joints. Taking HyaFlex™ helps maintain the normal viscosity of joint fluid.

What if my pet doesn’t have joint issues?
If your pet is not currently experiencing joint issues, then HyaFlex™ may be used to provide benefits in the long run. Just as we change the oil in our car to help stop problems, taking HyaFlex™ may help your pets by maintaining proper joint fluid viscosity. Also, hyaluronic acid production slows down considerably as pets age, which accounts for the joint issues, so it makes good sense to compensate with HA.

How do I give HyaFlex™ to my pet?
Just administer the specified amount (shown on the side of the box) of HyaFlex™ to your pet once daily. HyaFlex™ is odorless and tasteless so your pet won’t even notice it. Each bottle of HyaFlex™ contains a 30-60 day supply depending on the weight of the animal.

Where does the Hyaluronic Acid in HyaFlex™ come from?
The Hyaluronic Acid in Hya-Flex™ comes from an extracellular protein produced by natural fermentation. This product is not derived from any animal source. Hypersensitivity reactions should not be a concern. Natural fermentation can yield higher molecular weight HA. The weight of the molecule directly influences its “moisture-binding” capability, and HyaFlex™ has the highest molecular weight HA on the market. This may explain the phenomenal results we are experiencing.

How long has HA been used?
Hyaluronic Acid was first used commercially in 1942 when Endre Balazs applied for a patent to use it as a substitute for egg white in bakery products. He went on to become the leading expert on HA, and made the majority of discoveries concerning HA.

Because it is an acid will it burn mine or my pet’s skin or stomach?
Hyaluronic Acid is often called an acid and this is a misnomer. Hyaluronic Acid as a sodium salt (sodium hyaluronate)(HyaFlex™) will have a neutral pH measurement, not an acidic. Because of the water retention capacity of Hyaluronic Acid, it is actually a very good moisturizer for the skin and is being used.

I was contacted a little over a month ago by a man about HyaFlex. I run a Lab rescue and club here in Utah, and I was sent 3 samples. I kept one for a rescued Lab I have that has joint issues, gave one to my sister-in-law who has a senior Collie with the same concerns, and one to a friend at a shelter who has a Mastiff also with joint issues. All three dogs have improved significantly, especially my Lab. He is now able to run and play like my younger boy who is not afflicted. I will be advertising your product to all my club members, adopters, and friends! Thank you so much!!!

We tried the products on 12 dogs that varied in size from 10 to 86 pounds. 4 out of 12 dogs showed dramatic levels of jumping ability; 2 out of 12 showed moderate levels of activity after receiving HyaFlex.

Based on this limited study, I would conclude that in my professional opinion, HyaFlex is a product that I would recommend to my clients for use in their pets. In fact, I’m afraid to take my own dogs off HyaFlex!

My buddy, Snickers, is 14 years old, and he was starting to have some trouble jumping in the car, to go for a run, and getting up on the couch for a good petting. I have been using Hyaflex on his food daily for four years and I believe this has helped him a lot these last few years. Thanks, Hyaflex, for putting the spring back in Snicker’s step. His coat seems glossier, too.

I was recently approached by a company called Hyaflex to test about their product for older dogs. The compound has hyaluronic acid, the fluid that is in the joints of animals. I asked him to send me some samples to try on two old dogs, on 11 and the other almost 12. The 11 year I had concerns about. The 12 year old was not as serious, but still doing pretty well.

I have to say, I am truly impressed with this product. The 11 year old, after a week, was “sneaking” around the kennel at night to investigate – he was not crated as he could not get in and out of one. The 12 year old has turned into a puppy – to the point that she has become a bit obnoxious – running and barking at the other dogs. Needless to say, I will be placing an order for more of this product today.

No, I don’t sell it. It is the first thing I have found to really help the oldies. Our almost 12 year old is none other than the #2 highest living ROM Bitch, Silverhill’s Sumthin Special, OFA, ROM. I hope it keeps her active the rest of her life.


My dog Toby will be 14 years old this summer.We never thought he’d make it through this last year. I started Hyaflex as recommended by our vet. After a month he was doing so much better walking and now is much more alert and enjoying life again. We had used Flex|Free and Cosequin before but nothing has helped like Hyaflex.

Thank you for you product!
