Glucosamine is the building block of chondroitin sulfate, a specific type of polysulfide glycosaminoglycan (GAG), a small but complex molecule that plays an important role in the production and protection of joints. Glucosamine plays multiple roles within joint function and health. It helps increase the production of new GAGs and therefore new cartilage, has also been shown to help inhibit free radicals and enzymes that break down cartilage. 

Hyaluronic Acid (HA) helps support healthy cartilage and joint fluid. Hyaluronic acid is what makes joint fluid "sticky" because it is known to protect cells in the joint, HA is especially useful during periods of high-level joint stress.

MSM: (Methylsulfonylmethane) Assists body to produce its own internal antioxidants which helps support natural inflammatory response by providing protection against oxidative stress. It is a great source of sulfur, which plays an important role in maintaining the health of collagen, cartilage, hooves, hair and joint fluid.

Collagen is the main structural protein found in the connective tissues of the body (skin, bones, cartilage, tendons, and ligaments). Hydrolyzed collagen protein (gelatin) is a modified form that has been broken down into smaller pieces making it easier to digest and absorb. Collagen and gelatin help support joint health, nourish bones and the tendons/ligaments surrounding them.

Chondroitin Sulfate works synergistically with glucosamine in the production of new cartilage and inhibits the effects of various enzymes that breakdown cartilage. It also helps to support a natural inflammatory response lending to overall joint health and comfort.

Silica is the second most plentiful element on earth, yet horses may not receive adequate levels from their diets because not all forms of silica are bioavailable and it is easily destroyed in processing. Silica supports normal bone growth and density, helps maintain healthy connective tissue such as tendons and ligaments. Silica is required in cartilage formation and helps support the health of skin, hair and hooves.

Yucca is an herb native to North and Central America used by ancient and modern civilizations to address musculoskeletal discomfort. Active ingredients have been isolated from Yucca that have shown to have antioxidant properties to help support natural inflammatory response.

Devil’s Claw is a South African herb that is used for discomfort in bone, joints, and other tissues. Data from 14 clinical trials in people conducted over the last 40 years suggest Devil’s Claw has beneficial properties in the musculoskeletal system. Because it contains “bitters” as an active ingredient, which encourages appetite but also stimulates the secretion of stomach acids, it should be used with caution in those at risk for gastric (stomach) upset. It is also recommended to check competition rulings before using products containing Devil’s Claw.

Boswellia comes from the same resin of trees that produce frankincense. It contains naturally occurring compounds that are said to interfere with the enzymes that contribute to inflammation and discomfort.

Ester-C® (calcium ascorbate) is a unique patented ascorbate complex bound with calcium carbonate. Ester- C® is naturally processed in purified water without the use of alcohol or acetone solvents. This makes Ester-C® a more readily available, readily absorbed form of vitamin C. Vitamin C is an antioxidant that helps protect the tissues of the body and also important in the production of connective tissues like tendons and ligaments. Ester-C® has up to 4X more metabolic activity than standard vitamin C (ascorbic acid).

Zinc (Zn) is a micromineral involved in over 100 enzyme systems ranging from support of connective tissue formation and antioxidants to carbohydrate metabolism and immune system function. It is most recognized for its role in healthy skin and hooves.

Manganese is a micromineral that aids in bone formation, growth and reproduction. It also supports carbohydrate and fat metabolism. Supplementation should be considered because not all diets provide the same levels of manganese. It plays an important role in young growing horses as well as active performance horses.

Copper (Cu) is a micromineral that aids in the production of normal connective tissues including tendons, ligaments, cartilage and bone. As a component of many enzyme systems, it is also involved in making iron available to the body for blood, in producing skin and coat pigments, in proper nerve signaling and in repairing antioxidants.

I was wondering how this compared to Matrix 5 H/A? I have a 3 year old mare with some tendon issues and the vet suggested putting her on a supplement for it and I saw that some people preferred this product over the other for tendon problems.

MVP: Both the Matrix 5 H/A & Re-Inforcer EQ have high levels of joint support ingredients (glucosamine, chondroitin sulfate, MSM, and HA) while Re-Inforcer also contains soft tissue support (silica and collagen).  If you're not sure which may be the best option for your mare, we recommend working with your veterinarian to decide which may be the most beneficial for her individual needs.


If I give my horse the Re-Inforcer, does that mean I can stop giving him MSM?

MVP: Re-Inforcer EQ provides 12,000mg of MSM, so additional supplementation of this ingredient is generally not necessary.


Is this legal to feed horses competing at AQHA events?

MVP: Re-Inforcer EQ does contain the herb Devil’s Claw, which is listed as a Prohibited Substance under USEF rules. Therefore we do not recommend using this supplement for horses who show in AQHA or USEF competitions. Because the official lists may change from time to time, we encourage you to visit their database to search for prohibited substances. We also recommend checking the rulebooks for any other organizations under which you compete.

    Great product!

    Posted by Chelsie Kimich on 5th Sep 2023

    I just started using this product for mainly that joint support. Having a sport that’s hard on the horses joint takes a lot of wear and tear. She didn’t have any limping before but she does have a pep in her step and feels amazing! I will be ordering more of this product

    Reinforcer EQ

    Posted by Jane on 21st Apr 2023

    I have used Exceed 6 Way for years with my older mares. One of mares recently re injured her stifle, and I was running out of options to keep her comfortable, so I looked through the MVP catalog and found Reinforcer EQ. I have had her on it for about 3 weeks now and see an improvement in her comfort.

    Improved greatly

    Posted by Bonney on 2nd Jan 2017

    I have a 16-year-old QH mare who had soreness issues in her front feet in Jan 2016. I did lots of vet visits and at vet’s advice -- put her on a joint supplement for support. I started with Matrix 5 + HA in spring and have had her on Reinforcer EQ since fall. She has improved greatly and I love this product. I researched just about every ingredient in it and have found that it delivers the greatest quantities of what I need (Glucosamine, Chondroitin, HA, Yucca, MSM, especially), without having to customize other additional joint products. And the staff have been really helpful with advice and support. Thanks to her improvement, I’m headed out to ride this morning. Thanks very much!

    Placing at the top of her classes

    Posted by Laurie on 27th Nov 2016

    I started using Reinforcer EQ on our show mare in May. By our June shows she was placing at the top of her classes in halter and showmanship. We also noticed that she was striding much farther underneath herself. We believe her improved mobility helped her to earn over 40 first places this year and over 25 grand and reserves. She also was in both the Top Five and Top Tens at two world shows this summer. At age 16 we think that’s quite awesome! After our show season ended in October we had a product we had previously used for mobility and wanting to use it up we put our mare back on it . . .. needless to say our blacksmith noticed stiffness in the hind legs when he worked on our mare. She’s now back on Reinforcer EQ and is moving great again!

    I can see the results

    Posted by Penny on 25th Nov 2012

    I have been using Re-Inforcer Pellets on a 24-year-old retired mare for two months now. Since being on Re-Inforcer, she is trotting and cantering around her pasture more comfortably. I plan on keeping her on this supplement because I can see the results.
