Bring us your problem, we'll provide the NATURAL solution.

Nature’s Animal Products is a solutions driven company helping to solve the complex problems of the horse’s health from conception to competition and into the twilight years. Our revolutionary, all natural products can play a crucial role in regulating the immune system and keeping the airway clean and healthy.

Our company was founded by a group of industry leaders, including veterinarians and equine researchers, who have each had years of personal success using our unique group of products. Our mission is to provide a natural and progressive solution to problems with the immune and respiratory systems. These products have no contraindications, and can therefore be used to treat acute issues in conjunction with veterinarian prescribed medications. They can also be used as part of a maintenance regimen to aid in the prevention of future problems whether your horse is in training, competing, traveling or happy at home. These products treat the root causes of so many problems by balancing the immune system, keeping allergies at bay and reducing mucus and inflammation in the airway.

We have carefully tailored treatment regimens that we are happy to discuss with you or your veterinarian to best suit your horse’s specific needs.

California native Kirsten Johnson is the founder and owner of KESMARC (Kentucky Equine Sports Medicine and Rehabilitation Center) in Versailles, Kentucky.

With over 30 years of experience and a pioneer in the Equine Rehabilitation industry as well as a pioneer in Equine Hyperbaric Oxygen Therapy treating over 30,000 horses, Kirsten and her team has specialized in respiratory conditions of the horse.

Kirsten says – I have treated horses’ respiratory issues, complications of throat abnormalities, inflammation, and pre- and post-surgically and have never had the success I have now having using Nature’s Animal Products. I am so impressed that I became a part of this company. Whether it’s common allergies or a complicated pneumonia, bleeders, pre and post throat surgery, or a preventative treatment before and after shipping, treating sick foals and horses with compromised immune systems, this line of products has changed the game in terms of nebulizing and oral or throat spray. Don’t hesitate to call me personally if you have any questions on how to utilize this outstanding line of products.

Dr. Robert Holland

Known around the world as the person you call when you’re unsure about an equine infectious disease, Dr. Holland has helped to prevent and contain the spread of disease in many countries and jurisdictions. His practice focuses on respiratory disease, allergies, infectious disease, and also disinfection protocols for best practice in equine environments.

Focusing on diagnostics and treating with the right medication for a particular infection, Dr. Holland has had great success in saving time and trial-and-error which gets horses back to competition quicker.

Dr. Holland is well-known for solving cases that frustrate others by introducing many new therapies and diagnostics. Having had the unique opportunity to perform hundreds of endoscopic exams on horses at the racetrack during the sponging scare, he has an uncommon knowledge of equine throat anatomy which very few veterinarians share.
