MISMO MSM for Horses

MSM (Methyl Sulfonyl Methane) is a dietary source of sulphur, an element that is essential in the formation of connective tissue. Daily supplementation with MSM is widely acclaimed by veterinarians and equine professionals for helping improve equine health and performance. Although relatively new to Australia, MSM is a dietary supplement used throughout the equine industry in the US and across Europe.

Benefits of MSM for Horses

Studies have shown that MSM can be credited with helping reduce inflammation and improving circulation in performance horses (potentially relieving a host of equine ailments).

While MSM is present in most fresh food sources, even moderate processing, including the cutting and drying of hay, can result in the reduction of available MSM. Therefore, it is important to supplement most diets with a pure source of MSM. Nutritionists, veterinarians, and equine professionals continue to report excellent results from daily supplementation with MSM.

As the supplementation of MSM assists in the formation of connective tissue, feeding MSM will potentially reduce the effects of wear and tear on the joints and ligaments that high-mileage performance horses accumulate over time. Some specific conditions that MSM has been shown to assist with are:

  • Reduce inflammation
  • Promote circulation
  • Epiphysitis
  • Back discomfort
  • Arthritis
  • Autoimmune related conditions
  • Promotion of liver health

Directions For Use

Add 1-gram MSM per 45kg of body weight twice a day to your horse's feed, or as directed by your veterinarian. It’s encouraged to start horses off slowly (3-4gm or half a teaspoon, twice a day) and over the week build up to 10-12gm (or 2 heaped teaspoons) twice a day.

Hear From Our Ambassador

"I started taking MISMO MSM 6 months ago after a friend told me about the fabulous results they’d had with it. After having back surgery six years ago, I’ve become accustomed to poor quality sleep-waking 5-6 times a night and having to reposition due to back pain. I thought this was just my new normal after the surgery. I had massages regularly just to help keep mobile, and would constantly have back pain when standing or sitting for any length of time. But, as it was still a drastic improvement from my pre-surgical state, so I kept on going and learnt just to live with it. The results since I’ve started taking MISMO MSM have been extraordinary. Much to my amazement - I now sleep through the night, without pain, and feel fresh and mobile in the mornings. I recently drove my horse truck on a 2000km round trip from Mackay and could stand up straight the next day - like I hadn’t been sitting for 24 hours at all. It used to take a week until I’d recover even from a much shorter trip!

In light of such fabulous results, I have started all of my horses on this fabulous product. I’ve noticed that the older horses in particular have developed more freedom in their movement, and especially my FEI horses are finding their collected work easier. And from a cost standpoint - it’s one of the most economical supplements I feed. I highly recommend this fabulous product to all of my clients - both for their horses, as well as for themselves. MISMO MSM has dramatically improved my quality of life and I am beyond thrilled to be an ambassador for such a fabulous product."
