How do you find out if your horse is at risk of sand impaction colic?

What is Sand Colic?

Horses can graze very close to the ground, and when grazing on sandy soils, or fed in yards/stalls with a sandy floor, they can often inadvertently take in sand. Under most conditions this is not an issue, however under some circumstances due to the sand being heavy, it can accumulate in the hindgut and cause a blockage and abdominal pain. The movement of sand through the intestines depends on the rate of passage of the digesta (undigested food).

The accumulation of sand can be exacerbated when the rate of passage is slow. What you can do:

  • Provide hay or feed in feeders off the ground
  • Avoid over-grazing if possible
  • Include a supplement that swells when added to water to assist the clearance of sand


  • Intestinal support for horses on sandy conditions
  • May assist with the removal of sand

SandBuster is designed to feed to horses exposed to dry or sandy conditions, where an accumulation of sand in the hind gut may have occurred. SandBuster contains a blend of ingredients each selected because of their unique action on causing increased rate of passage, becoming gelatinous and supporting intestinal mucosa repair.

SandBuster can be fed wet or dry. We don't recommend soaking it, we recommend feeding it immediately after adding the water so that the Sandbuster is still swelling and becoming sticky as it is fed to get maximum benefits.

About the Ingredients

Psyllium Husk

Psyllium is a form of fiber made from the seed husks of the Plantago ovata plant. Psyllium contains both soluble and insoluble fibre. The soluble fibre expands 10 times the original volume in water to form mucilage. Research shows that this passes undigested through the intestinal tract increasing the rate of passage of digesta and sand through the gut.

CoolStance - Copra Meal

Coconut (copra) meal also contains both soluble and insoluble fibre, and swells 5 times its volume in water and therefore may assist the passage of digesta. CoolStance coconut meal also assists palatability.


Montmorillonite is an absorbent clay mineral that swells 5 times its dry volume in water. It acts as an indigestible gelatinous lubricant.

I love that SandBuster can be included in small amounts daily or at the recommended feeding rate monthly and then as required. We will definitely be keeping our ponies on this fantastic supplement!- Stephanie

My ASH had a round of SandBuster at the start of the month. What a great product, it has worked wonders! We had been trying straight psyllium husks once per month and they helped a little but not that much, but the SandBuster worked way better and had a longer lasting effect which is fabulous. I'm now feeding SandBuster once a month. -Leanne
