Carb-X (Meal)


"I bought this for my overweight horse to control her weight. I mix it with her lite grain and she has no problem eating it. So far she is still too fat. I've only had it for less than a month so hopefully I will see results as time progresses."

Adult Horses (900-1,100 lbs): Provide 1 to 2 oz daily.





Magnesium (Mg) is a vital macromineral, and it is becoming increasingly recommended by veterinarians for various treatments in the horse. Because one of the clinical signs of magnesium deficiency is nervousness, it is added to many calming supplements. Magnesium helps protect against inflammation and free radical damage. Magnesium may play a role in insulin resistance and equine metabolic syndrome. Within the muscle calcium and magnesium work antagonistically — calcium causing muscle contraction and magnesium inducing relaxation. If there is not enough magnesium, muscles tend to spasm. Although the presence of low magnesium in the muscle tissue may stem from a genetic disorder rather than dietary quantities, there are reports of horses that have responded to magnesium supplementation for treatment of chronic tying up.

Chromium is a trace mineral which works with insulin to regulate blood sugar. By helping insulin work properly, it may be useful in managing the insulin resistance seen with Equine Metabolic Syndrome and in managing excitable horses on high grain diets that "tie up" due to stress. However, because PSSM horses display abnormal insulin sensitivity, chromium may not be recommended for horses with this particular muscle disorder. Siberian Ginseng is an herb that has been used in China for thousands of years to increase energy and stamina, help the body resist infections and toxicity, and restore memory and concentration.

Siberian ginseng is believed to act as an "adaptogen," a substance that normalizes body functions, strengthens systems compromised by stress, and protects against a wide variety of stressful influences. This herb can be found in products designed to support proper metabolism and immune function.

Lipoic Acid is found in the body and also synthesized by plants and animals. It’s present in every cell inside the body and helps turn glucose into “fuel” for the body to run off of. A 2017 study examined the effects of alpha lipoic acid on blood glucose levels and found that it helps sustain normal blood glucose levels and insulin sensitivity.

Taurine is an amino acid (a building block of proteins) that plays a significant role in nervous system function and provides support for calming and mental focus. Also supports heart and muscle function along with liver and nervous system health. It can be found in supplements for growing horses, nervous horses and horses with metabolic issues.

Biotin is a member of the B vitamins family and, like some other vitamins, is a coenzyme for several metabolic pathways. It is involved in glucose metabolism, growth and utilization of niacin. Biotin is essential to the growth of strong, healthy hooves due to its role in collagen formation. A number of research studies show that longterm, daily supplementation of 10-30 mg of biotin daily improves the growth rate and hardness of hooves, especially in horses with less than optimum quality hoof horn (soft, brittle, chipped).

Grape Seed Extract is a very potent antioxidant for horses requiring immune support. It helps protect against tissue damage from oxidative stress resulting from free radicals generated during equine exercise, immune system activity or environmental exposures.

Gymnema sylvestri extract is derived from the leaves of a climbing plant native to the forests of central and south India. The leaves of the gymnema sylvestre plant contain gymnemic acids, which have been shown to slow the transport of glucose from the intestines to the bloodstream. It has also been shown to aid in weight loss and digestion.

Ginger is a plant that has been used for thousands of years in Asia primarily as a digestive aid to prevent nausea, vomiting and stomach ache. Other positive effects in humans include reducing cholesterol and preventing platelet clumping, helpful in a variety of cardiovascular conditions.


Do you have any tips on how to get a picky metabolic syndrome horse to eat supplements?

MVP:  Find a low sugar “carrier” that your horse will eat and gradually mix in the supplement.  Some low sugar options are; commercial feed formulated for sugar-sensitive horses (NSC level of 10% or less), shredded beet pulp (no molasses), hay cubes broken into pieces (choose a hay cube that is 10% NSC or less) or alfalfa pellets. Only use a small amount of carrier ingredient (1 cup per feeding or less if a mini). Once your horse readily eats the carrier ingredient, add a small amount of supplement and mix well.  Over the next few days gradually increase the amount of supplement until you reach the full serving size.  Soaking the carrier with a small amount of water may make the supplement mix in better and harder to leave behind. Add the supplement right at feeding time, do not soak.


I would like to start my mare on a metabolic supplement, there are so many to pick from. What sets them apart, they seem similar?

MVP: In review – The most essential ingredient to feed an IR horse is a minimum of 5,000mg/5gm of Magnesium. Chromium and iodine are also very beneficial when the diet is lacking these nutrients.

Anti-Carb – Should be given to a horse that is already on a balanced vitamin/mineral supplement.

Carb-X – An herbal approach to treating IR, Contains good levels of magnesium and chromium along with herbals that may be beneficial.

D-Carb Balance – Provides the Vitamins/Minerals that are lacking in a low quality diet for IR horses.

Magnesium 5,000 – Should be given when an all-around vitamin/mineral supplement is lacking in high levels. This is the minimum someone should do with an IR horse and is great for those on a budget!

Actually begs for it

My 28 yr old Mustang is probably the pickiest horse in the world and has Cushings. I’ve tried every trick in the book to disguise his meds and metabolic supplement. I decided to try CarbX but couldn’t tell from the website if it was flavored, which makes a big difference to a horse with a picky palate! Cust. Service didn’t know said they’d find out and contact me. I figured I’d never hear back but the NEXT day someone replied w/ the info I needed. I was very, very impressed and now very, very happy. My horse LOVES Carb X & actually ’’begs’’ for it! He’s doing even better now as I can mix in his meds in his food along with the CarbX and he licks his feeder clean! Highly recommend it and recommend using United Vet Equine-nice people!
