What does HA do for my cat's joints?
The HA in HyaFlex™ helps to improve joint movement and cushioning. If we compare the joints of your cat's body to and 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 oils viscosity. The oil becomes thinner and less able to protect the metal surfaces from excessive wear. HyaFlex™ acts the same way in our joints. As your cat 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 cat doesn't have joint issues?
If you are 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 cats by maintaining proper joint fluid viscosity. Also, hyaluronic acid production slows down considerably as cats age, which accounts in part for the wrinkling of the skin, and the joint issues, so it makes good sense to compensate with HA.

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

Where does the hyaluronic acid in HyaFlex™ come from?
The hyaluronic acid in HyaFlex™ 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.

Do doctors and veterinarians use hyaluronic acid?
Yes. Hyaluronic acid has been directly injected by needle into affected joints. This has yielded great results by immediately increasing the viscosity of the joint fluid and restoring proper lubrication and cushioning. More work has been done in the field of orthopedics, cosmetic and eye surgery.

Because it is an acid, will it burn my or my cat's skin or stomach?
Hyaluronic acid is often called an acid and this is a misnomer. Hyaluronic acid as a sodium salt (sodium hyaluronate) will have a neutral pH measurement; not an acidic pH measurement. Because of the water retention capacity of hyaluronic acid, it is actually a very good moisturizer for the skin and is being used in many facial cream and body lotions.
