UltraCruz® Mineral Oil Light for Horses

  • Effective as a mechanical laxative
  • Lubricates the intestines
  • Helps soften stool and clear impaction
  • Oral liquid safe for internal use

UltraCruz® Mineral Oil Light for Horses is a liquid petrolatum that has been refined for internal use as a mild laxative. This product is safe for use in horses, cattle, sheep, goats, pigs and dogs to help clear intestinal impaction or obstruction. Mineral oil lubricates the intestinal tract and helps soften stool, making it useful for animals suffering from constipation. This mild laxative is safe for oral administration to animals.

Mineral oil acts as a laxative by lubricating fecal material and the intestinal mucosa. It also reduces reabsorption of water from the gastrointestinal tract, thereby increasing fecal bulk and decreasing intestinal transit time.

Mineral Oil for Horses - Shiner's Little Oak and Charismatic Oak next to each other

Some horses naturally clear sand from their digestive tract more effectively than others. Researchers have found that using a combination of mineral oil and psyllium is more effective overall than administering mineral oil alone.

Mineral oil is totally inert within the gastrointestinal tract. There is no absorption of mineral oil, which allows it to arrive in the hind gut to exert its effect. Sometimes, mineral oil is administered after an animal ingests lipid-soluble toxins to help prevent the absorption of these toxins through its laxative properties and solubility.

To help remove sand from the digestive tract of horses, we recommend using UltraCruz® Equine Pure Psyllium Supplement for Horses.
