Ulceraser™ contains:

  • L-glutamine and L-proline, which stimulate production of the mucosa that protects the gastrointestinal tract from acid, support development of the intestinal cells responsible for nutrient absorption, and assist in rebuilding damaged tissue.
  • Omega-3 fatty acids[1] known to reduce swelling and inflammation, and boost the immune system.
  • Hydrophilic ingredients that assist in clearing sand and unwanted debris from the gut.
  • Naturally occurring magnesium, tryptophan[2] and glutamate, which assist anti-stress inhibitors that reduce anxiety and nervousness.
  • L-arginine[3], which is the precursor to nitric oxide that increases blood flow to damaged tissue, helps reduce inflammation, promotes the healing process of ulcers, and helps prevent additional ulcers from developing.
  • L-lycine[4], which aids in healing gastric lesions.
  • L-glycine[5], which is essential for a healthy functioning digestive system, and is known to inhibit gastric secretion and protect and repair gastric mucosa.
  • L-serine, which inhibits gastric secretion and protects gastric mucosa. Serine is also needed to produce tryptophan, the amino acid precursor to serotonin, which helps reduce nervousness and stress.

Up to 90% of Performance Horses Have Ulcers

A horse’s stomach is divided into two parts. The lower region, which contains a mucus coating for protection from the gastric acid secreted, and the upper region, which lacks the thick mucosa prevalent below. Ulcers can occur in either part of the stomach, but occur most frequently in the upper portion because it lacks the protection found in the lower stomach.

Horses produce gastric acid 24 hours a day whether they are eating, sleeping or exercising. Without constant foraging, this acid irritates their stomach and intestinal lining.

Due to many environmental factors, it is estimated that approximately 90% of performance horses have ulcers. The main causes of ulcers include:

  • Stress (caused by training, competition, shipping, injury, etc.)
  • Use of nonsteroidal anti-inflammatory drugs (i.e. phenybutazone, banamine)
  • Limited access to turnout and grazing
  • Infrequent feedings
  • Large grain meals

Lack of constant roughage combined with intense exercise, competition, travel, and frequent use of harsh non-steroidal anti-inflammatory drugs, can result in painful ulcers. Signs of ulcers include:

  • Irritability
  • Weight loss
  • Resistance to leg
  • Dull coat
  • Anxiousness
  • Poor appetite
  • Mild colic and colic-like symptoms
  • Spookiness
  • Poor performance
  • Girthiness

Prescription drug treatment of ulcers falls into different categories. Drugs such as omeprazole and ranitidine shut down the production of acid from the gastric pumps. Other drugs, such as misoprostol are synthetic prostaglandins that target inflammation in the colon. Though prescription drugs can treat ulcers, the goal is to prevent their formation or recurrence. Gastric health and ulcer
prevention can be managed through dietary supplements that assist in healing and protecting the stomach and intestinal linings.
