Gastro Elm Plus


Gastro Elm Plus for all GI Issues.

A decade of amazing results! GastroElm Plus has helped thousands of dogs, cats and horses with severe GI issues since 2013. 

Support for:

  • Ulcers and Colic
  • IBS and Leaky Gut
  • IBD and Colitis
  • Pancreatitis
  • Elevated Liver Enzymes 
  • Acid Reflux
  • Other GI Issues

GastroElm Plus was originally formulated to manage pancreatitis symptoms and other digestive disorders in dogs but has proven equally effective in cats and for ulcers, colic and other conditions in horses. Since each big bag contains more than 90 doses (for large animals), it is extremely cost effective compared to prescription based alternatives, as low as 50 cents per dose. It’s even more cost effective for animals under 20 pounds at as little as 50 cents per week!

If your animal has a sensitive stomach or is a finicky eater, GastroElm Plus is the perfect solution to avoid future vet bills. It’s also great for dogs who tend to get into things that they shouldn’t be eating. Simply give them a dose whenever stomach upset arises.

It is manufactured in the USA (Fargo, ND) using a proprietary blend of high quality human grade Milk Thistle Seed Powder, Dandelion Root Powder and Marshmallow Root Powder blended with the finest Appalachian wildcrafted Slippery Elm Bark Powder.

It forms a smooth gel that acts almost like an internal bandage when mixed with water. It coats and soothes the stomach and digestive tract to help the animal feel better very quickly.

Proprietary Blend of:

  • Slippery Elm Bark Powder
  • Dandelion Root Powder
  • Marshmallow Root Powder
  • Milk Thistle Seed Powder

Slippery elm soothes and lubricates the mucous membranes that line the digestive tract. That makes it an excellent treatment for ulcers, gastritis, colitis and other inflammatory bowel problems. It’s high in fiber, which helps normalize intestinal action. This means it can be used to relieve both diarrhea and constipation. Our slippery elm powder is specially ground to easily mix into a smooth gel instead of being clumpy, so it’s easy to use with an oral syringe if needed.

Milk Thistle is supportive to the liver and other vital organs to aid in long term health. Since it is a powerful liver cleanser, it helps rebuild liver cells while removing toxins from the body that are processed through the liver. Milk thistle is effective at naturally reversing the harmful effects of pesticides in the environment and food supply, heavy metals in the water supply, pollution in the air that we breathe and even poisons!

Marshmallow Root helps restore integrity of the gut lining by forming a protective layer around small junctions (avoiding leaky gut). In addition, it seems to be beneficial for inflammatory bowel diseases, including ulcerative colitis and Crohn’s disease.

Dandelion Root has many nourishing and healing properties for the digestive tract. Additionally, the antioxidants in dandelion root have been shown to be supportive to the liver as well. It also possesses antimicrobial properties that can help stop the growth of disease-causing bacteria.

All four herbs work in conjunction with one another in a way that has proven to be most beneficial.


The Big Bag makes 90 batches for a horse or large dog and up to a two year supply for small animals!  

The Small Bag makes 50 batches for a horse or large dog and approximately a one year supply for animals under 20 pounds. 

A Batch is 1 tablespoon of powder mixed with 4 ounces of water.  It is a one day supply for a large dog (over 100 pounds), one serving for a horse and a one week supply for animals under 20 pounds.


Mix 1 TBSP of powder with water or bone broth. Mix well into a gel. For each pound of body weight, give  1/2 ml of gel via oral syringe before breakfast and at bedtime. Example: 20lb dog X .5 = 10ml per dose. 

For maintenance: Mix gel into food once or twice a day as needed.

Mixing tips: Start with 4 oz of water or bone broth in a container with a lid, add 1 TBSP of GatroElm Plus powder. Put lid on and shake for 10 seconds then allow to sit for a minute to allow it to form a smooth gel consistency. Use an oral syringe to measure dose for your pet. Leftover gel can be stored in fridge for up to 1 week. If you find the gel is too thick, add a little more water.

For cats

For horses

You can mix 1 1/2 tablespoons of powder with 6 oz of water or aloe juice for horses with stubborn ulcers.  In that case people usually syringe it 10-15 minutes before feeding.  
In most cases, top dressing feed with the dry powder works fine.

Dry dosing:
A tablespoon of powder (3 teaspoons) is the correct dose for 120 lb dog or for a horse.  If the pet weighs 10 pounds you divide 10/120 = .083

3 x .083 = 1/4 teaspoon so that would be 1/8 of a teaspoon in the first and last meal of the day.

So basically if an animal is 10lbs do 1/8 teaspoon twice per day, a 20 lb animal is 1/4 teaspoon twice per day etc.
