4-in-1 H/A is an all-in-one supplement designed for horses in light to moderate work. Formulated to support healthy joints, hooves, coat & digestion in a tasty easy to feed pellet.

  • Joints plus H/A!
  • Coat
  • Hooves
  • Digestion


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.

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.

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 helps aid in the growth of strong, healthy hooves due to its role in collagen formation. A number of research studies show that long-term, daily supplementation of 10-30 mg of biotin daily may help improve growth rate and hardness of hooves, especially in horses with less than optimum quality hoof horn (soft, brittle, chipped).

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.

Linolenic Acid (Omega-3): Omega-3s play an important role in supporting immune health, skin/coat health and in helping to support a healthy response to inflammation throughout the body.  To help modify the inflammatory response of a horse’s body to stimuli like exercise, the Omega 3 to 6 ratio needs to be kept in balance. Diets that contain a lot of grain or high Omega 6 oils like corn or sunflower oil may cause your horse’s diet to contain more Omega 6 than Omega 3 fatty acids. The ideal ratio of omega 3s to omega 6s has not been formally established. It makes sense, however, to strive toward the ratio that naturally exists in grasses: three to four times more Omega 3 than Omega 6.

Linolenic Acid (Omega-6): Omega-6s are fatty acids that are responsible for the inflammation and immune responses in the body which are necessary to support injury recovery and combat infections. Omega 6 is just as important in the diet as Omega 3, they just need to be kept in balance with one another to support a healthy inflammation response. 

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.

Methionine is an amino acid that must be provided in the diet since the body cannot create enough of its own. This means if it is not present in adequate amounts it limits the body's ability to make protein. Methionine can be converted by the body into another sulfur-containing amino acid, cysteine. Because the concentration of both these amino acids is highest in hoof and hair, methionine is often included in hoof health supplements. 

Lysine is an amino acid and the only one for which a requirement in the horse has been established by the NRC and used for the biosynthesis of proteins. This amino acid is often the key to improving protein availability and healthy muscle function.

The Vitamin B family is made up of several compounds that support many important roles in the body: protein, fat and carbohydrate metabolism; energy production; proper nerve cell transmission, reproduction, and division (especially rapidly dividing ones such as red blood cells). B vitamins include thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), folic acid (B9), cyanocobalamin (B12), choline, biotin, inositol and others are sometimes referred to as B-vitamins. For most of the B-vitamins, microorganisms in the large intestine make all the horse needs. Only thiamine and riboflavin have NRC dietary requirements. However, research suggests B-vitamin supplementation may be beneficial to horses with little access to fresh pasture and/or during any periods of stress (training, injury, travel, etc.)

Probiotics are live microorganisms (bacteria and yeast) that help promote healthy digestive function and support a healthy immune system. Often referred to as ‘good bugs’ they help break down ingredients/contents that the body normally can't, and help inhibit ‘bad bugs’ from growing.

Is the loading dose mandatory?

MVP: The loading dose for this supplement is not required, and you may certainly start with the regular maintenance dose.

I see information regarding the ingredients but have there been any independent lab tests done to verify that the ingredients quantities match the label?

    Great Supplement for Daily Care

    Posted by Corrin Daggett on 8th May 2023

    I use this supplement on my 6 year old mare that I barrel race and my 18 year old retired mare who lives her life out in the pasture and they both look and feel amazing! Their coats are shiny, hooves are strong, and seem overall their best when on this supplement.

    Fantastic Supplement

    Posted by Caroline Ventura on 25th Apr 2023

    I showed and train on the rated Arabian circuit. Started using 4-N-1 +HA July 2022. What a difference it has made in the overall condition of my Arabian Lusitano cross. His coat and hooves look great and he is moving with more fluidity. Highly recommend

    Great for rehab conditions

    Posted by Karen L Casto on 7th Dec 2021

    This product made a mare with a hip injury so much more comfortable and helped make it possible for us to really move her reconditioning along. Really recommend this product. Also, really like it on my young horses it seems to help prevent stifle soreness. Responsible Horsemanship

    A must have for working horses!

    Posted by Katie Nolte on 8th Oct 2021

    We have been using this product throughout late summer and into fall and have noticed a big change in our mounted shooting horses. They work hard and travel long distances and this supplement has been a wonderful additive to their diet! Their coats look amazing, feet are stronger than every and they are more fluid through their movements. They also overall seem more genuinely happy. We use this product along with GastroPlex paste (given each morning of competition and before long hauls). We love all of the MVP products we have used and are still using. I highly recommend this product for working horses!

    Great product! My 15 y.o. OTTB started on the 4-in-1 and did well however, on the 4-in-1 H/A he’s moving better, his coat issues have virtually disappeared and his hooves are doing well in the AZ monsoons. Thanks!

    Would not even consider changing to another product

    Posted by Susan on 6th Jan 2013

    I have been using MVP 4 in 1 with HA for a number of years and would not even consider changing to another product. All of my horses are in training. They have excellent coats, are healthy and have lots of energy. It is very convenient to give my horse one supplement instead of four different ones to cover their needs.
