If Gut Restore is for serious gut repair and Gut Protect is for daily maintenance, Adoptrex sits in a slightly different lane – it's particularly well suited to dogs with sensitive, reactive digestive systems that seem to fall apart at the slightest change.
You know the dog. Every diet tweak causes loose stools. A bit of stress and they're vomiting. They can't handle any dietary fat without it becoming a problem. Their gut just never seems to settle into a reliable rhythm.
Adoptrex is a Dr. Steve Marsden formula built on two classical Chinese herbal combinations – Xiao Chai Hu Tang and Wei Ling Tang – which together address both the inflammatory and the "damp" digestive patterns that show up in these dogs. In plain terms: it helps regulate stomach motility, reduce gut inflammation, balance flora and strengthen the gut lining so the digestive system becomes more resilient over time, not less.
The tip in the dosage section about starting the herbs a week before a planned diet change is genuinely useful. If you're transitioning your dog to raw and they have a history of digestive sensitivity, starting Adoptrex a week before you begin the transition can make the whole process significantly smoother.
How it compares to the other gut formulas in this store:
- Gut Restore = active gut damage, IBD, leaky gut, post-antibiotic recovery
- Gut Protect = daily maintenance, variable stools, anal gland support
- Adoptrex = sensitive, reactive digestion, diet transitions, gastritis, sluggish or erratic motility
- Pure SB = specifically for antibiotic-associated gut flora disruption
- All of the above can be used together for a gut reset.
Best for dogs with:
- Sensitive stomachs that react to every food change
- Recurring vomiting or loose stools without a clear cause
- Sluggish digestion, bloating or excessive mucus
- Gastritis or chronic gut irritation
- Dogs transitioning to raw or fresh food
- Stress-related digestive upsets
Digestive & Immune Support for Dogs
Adoptrex is a powerful herbal formula created by world-renowned holistic vet Dr. Steve Marsden and produced by Gold Standard Herbs. It’s designed to support healthy digestion, reduce inflammation, and restore balance to your dog’s gut and immune system.
This unique blend combines two classical Chinese medicine formulas—Xiao Chai Hu Tang (Minor Bupleurum) and Wei Ling Tang (Five Herbs & Poria Combination)—giving it a wide reach for gastrointestinal issues.
Why choose Adoptrex?
Many dogs have sensitive stomachs. A sudden change in food, a cheeky bin raid, or even stress can trigger vomiting, diarrhea, or a complete loss of appetite. Over time, this can lead to more serious issues like gastritis, pancreatitis, or leaky gut.
Adoptrex helps by:
Strengthening digestion – improves enzyme production and regulates stomach motility, so food is broken down properly.
Reducing inflammation – so the gut lining can heal and stop the cycle of irritation.
Balancing gut flora – keeps bacteria in check, reducing “garbage gut” episodes.
Easing symptoms – supports dogs struggling with vomiting, loose stools, bloating, poor appetite, or excessive mucus.
Boosting immunity – a healthy gut means stronger overall immune defenses and less risk of food sensitivities.
When to use Adoptrex
Dogs with sensitive stomachs that react to every diet change.
Chronic digestive problems like gastritis, pancreatitis, or leaky gut syndrome.
Dogs with recurring loose stools, vomiting, or lack of appetite.
Pets prone to “damp” conditions in Chinese medicine—sluggish digestion, bloating, or mucus build-up.
As support during diet transitions, especially when moving to a fresher, healthier diet.

Dosage
Adoptrex is an organically grown concentrated herbal extract in powdered form. If possible, start using the herbs a week or more before any diet change, and make those changes gradually over three or four days.
To use, just fold the herbs into your pet's food, or shake them up with broth or water and pour them over top.
As a suggested starting dose, give twice daily as follows:
Up to 7 kg: ⅛ tsp
7 – 18 kg: ¼ tsp
18 – 32 kg: ½ tsp
32 – 50 kg: ¾ tsp
Over 50 kg: 1 tsp
If benefits are not seen, the dose can be safely doubled
One bottle of Adoptrex lasts over a month for medium dogs (up to ~23 kg), and about two weeks for large dogs (around 45 kg).
Adoptrex has even been credited with helping dogs through acute pancreatitis and diabetes mellitus, thanks to its ability to restore digestive power and calm the gut. With a stronger stomach and healthier gut lining, your dog can enjoy food again—without the fear of an upset tummy or constant flare-ups.
