Joint health can affect the very nature and quality of life—and the lives of those you care for. That’s why we’re committed to bringing you the highest quality, most innovative health products on the market. Below are some of the more frequently asked questions we hear—and their answers.

What is Cetyl Myristoleate?

Cetyl myristoleate is a unique esterified fatty acid with unique properties that have been shown to support joint health, function and mobility. Dr. Harry Diehl discovered its unique joint health properties while working at the National Institute of Health. Cetyl myristoleate is derived from myristoleic acid, which occurs naturally in the African Kombo Nut (wild nutmeg), whale fat and beef tallow.

Can’t our bodies simply make their own cetyl myristoleate from other foods?

Unfortunately, they cannot. For most animals, including dogs, horses and people, cetyl myristoleate must come from an outside source—and it works because of its unique molecular structure. Subjecting cetyl myristoleate to extreme heat or pressure, such as occurs in the manufacturing process with pelleted and extruded products, can have a degrading effect—and can lower its beneficial properties for joint tissues. That’s why we DO NOT pellet or extrude any of our products that contain cetyl myristoleate.

How does Cetyl Myristoleate work?

The precise mechanisms and metabolic pathways that apply to cetyl myristoleate in supporting and maintaining joint health are not fully known. Empirical data, however, has clearly demonstrated the positive role this powerful fatty acid can play in joint health for people and companion animals.

How long until these joint health products start working?

They start “working” right away, even though it takes a period of time for their effects to become evident. There are a number of factors that affect this start-up period, including age, formula, dosage and the condition of the joint tissues to start with. The CM Response™ and Cetyl M® formulas support joint tissues and function at the cellular level. For each formula, the recommended time and dosage for the initial “loading” period and subsequent maintenance program are based on averages. In nature, of course, there is no such thing as “average.” Be sure to monitor the condition closely and adjust as necessary to help ensure optimum results.

Is a “loading period” necessary if glucosamine is already being taken?

Yes. Cetyl myristoleate-based formulas affect joint tissues in ways that are unique and specific to cetyl myristoleate and are DIFFERENT than glucosamine. One ingredient does not work as a substitute for the other. In the CM Response™ and Cetyl M® formulas, cetyl myristoleate, glucosamine-HCl and other joint health ingredients work together to deliver optimum support for joint health and tissues. Always monitor conditions closely and adjust as necessary for best results.

Should I use the topical cream or the dietary form?

While the formulas are similar, their methods of delivery offer two very different—and powerful tools for achieving your joint care objectives. The dietary form offers a sustained, long-term systemic approach when using the formula as recommended on a daily basis. These levels in the blood stream and in joint tissues are such that they support joint health and function throughout the entire body. In contrast, the topical cream is applied and absorbed in local areas where it may be most desired. As a result, the topical cream provides more immediate, targeted and short-term support. Many of our most satisfied customers use both the oral and topical forms for maximum results.

How long should I use these products for myself, for my horse or for my dog?

The answer to this question is impossible to know with certainty, depending on a number of variables. For best results, regular and daily use is recommended as provided on the product label to support and sustain joint health. You may choose to increase the maintenance dosage when activity and stress levels are high or after an injury has occurred. All formulas are designed so they may help ease the aching and discomfort that often result from heavy activity, training and competition.

Are there any side effects?

There are no known side effects with the CM Response™ and Cetyl M® formulas. All ingredients are naturally occurring and formulated to support joint function. There are no synthetic compounds, drugs or medications in any of these formulas.

Will these products interfere with other medications?

Doctors and veterinarians have been using and recommending the Cetyl M® and CM Response™ formulas to support joint health and performance without restriction and without incident since their introduction in 1998.

Do I need to worry about a possible allergic reaction?

If you or your animal has a known allergy, we recommend you check the ingredient list carefully with your doctor or veterinarian beforehand. The glucosamine used in the Cetyl M® formula for horses and dogs is derived from shellfish, which may be of concern to owners with pets allergic to shellfish. Should your animal develop a reaction to any product, always contact your or veterinarian immediately.

*We suggest that people considering adding any dietary supplement regimen for themselves or their pet to discuss this decision with their doctor or veterinarian.
