Welcome to the MSM for Animals Home Page


1-lb, 10 lbs and 33 lbs containers of pure MSM Powder.


Why Use MSM for Dogs, Cats and Horses? 

1-lb MSM Powder MSM is often recommended by veterinarians for horses, dogs and cats that with joint problems, or to improve their general health. MSM is also widely used by many race horses owners. MSM is recognized by equine veterinarians for its overall health benefits for horses, based on extensive research showing the importance of MSM as a dietary source of sulfur.


Dog and cat owners may also wish to consider our chewable tablets designed with taste appeal for small animals.  Arthrix for Dogs and Cats, was especially designed to reduce joint problems in pets.

10-lbs MSM PowderKALA Health offers the purest for of MSM, branded PurforMSM.  It is offered in small as well as bulk quantities to consumers.  PurforMSM is made with the same technology as OptiMSM which is Bergstrom Nutrition MSM for humans. MSM has a very long shelf life (at least ten years) and will remain flowable rather than become hard as a brick, a common problem with less expensive MSM brands.


 PurforMSM is methylsulfonylmethane (Click here to read more about the Quality of MSM). This licensed form of MSM is approved by FDA for animal use. Unlicensed MSM, imported from China or India is currently flooding the market.  This MSM will not give the expected health benefits. You should consider the health risk of these low grade MSM substitutes, and look only for patented PurforMSM.


MSM for Horses


Veterinary interest in MSM continues to grow. However, MSM has been used on horses for 30 years. In 1983 John Metcalf, DVM, a well-known equine veterinarian, started the use of MSM to treat a variety of illnesses in horses. He has published his findings in peer-reviewed scientific periodicals, and shown that MSM is of great value in maintaining the overall  health of horses.


MSM is now widely used by veterinarians and horse owners for equine health care. KALA Health offers MSM in quantities of 1-lb, 10-lbs and 15-kgs (33-lbs).  Our MSM powder is the highest quality, human grade MSM (methylsulfonylmethane). Our patented and licensed MSM is the only MSM approved for animal use (US Patent 4,616,039 and other US and international patents). 

Directions for Use

MSM is a naturally occurring, bioavailable sulfur compound. Sulfur is an indispensable nutrient and should be taken daily for optimal health and nutrition.


For dogs and cats we recommend mixing 500 mg MSM powder per 10 lbs of body weight in your pet's food daily.  


For horses we recommended feeding one tablespoon (approx. 12 grams) MSM powder twice daily for the first 7 days. Feed one heaping tablespoon thereafter for daily maintenance.
