Firstly, and full disclosure, resetting the KPU disorder is no sprint - it's a bit of a marathon, and for some horses can even take up to 2-years.

Don't lose heart though - it's relatively straightforward, starting with an easy-to-follow 2-month detox. Thereafter it's a simple daily dose of activated vitamin B6 (P5P) for at least 1-year, alongside a recommended annual gut cleanse and a liver/kidneys detox at each coat change time.

Our own experience with one of our KPU ponies took 15-months. Be mindful, however, that depending on the degree of metabolic disruption, the regeneration can take longer for some horses.

What is KPU in Horses?

KPU, or Cryptopyrroluria, is a complex metabolic disorder tied to a disrupted hindgut microbiome. Known as the "disease with a thousand faces," it presents with a wide range of never-ending symptoms, including gut disturbances, skin and hoof issues, tendon or ligament swelling, persistent coughing, and even headshaking.

At its core, KPU stems from a deficiency in Pyridoxal-5-Phosphate (P5P), the activated form of vitamin B6. This critical micronutrient, normally produced in the hindgut, is essential for the liver and kidneys to metabolize toxins. When P5P production is disrupted, the body’s detoxification process falters, leading to the metabolic imbalances that define KPU.

Alleviate

First, we start alleviating the gut discomfort and inflammation with DuoBute , formulated to be very gentle on the fragile gut mucosa.

• Feed for a couple of days in a p.m. feed to start taking the edge off, before starting the detox. Continue feeding until finished.
• Optional - if your horse is stressed, also feed a 1-month course of StressTonic .

Detox

Stage 1 - Gut Stabilisation

Once your horse has had a couple of days on the DuoBute (and StressTonic if feeding), now we start the detox.

Feed the KPUCOMBO gut:liver stabiliser in an a.m. feed for 1-month, then take a few days to assess. It's important to see how your horse's gut functions following the supplement; depending on the historic degree of gut damage, it may be that a 2nd month's course will need to be fed.

• A 1-month course of KPUCOMBO - a combined blend of EquiNatural's SiboCARE , GutAminos , P5P (Activated B6), B12-Balance & Spirulina .

Stage 2 - Detoxification

We now tone the body's detoxification organs - liver, kidneys, lymph nodes. This addresses the body's natural detox process and resets the liver:kidneys:lymphatics pathway to support immune function and metabolic health.

• A 1-month course of LKLCARE

Top Tip: For fussy eaters, start slow! A pinch of each at a time and slowly build up.

Important Note: Supplements of any kind should be fed with caution to the pregnant or nursing mare so always seek veterinary advice.

The focus now is on maintaining your horse's health long-term. By feeding tonifying supplements to support a balanced gut microbiome, alongside a diet rich in healthy, natural nutrition, you'll be giving your horse the best chance to thrive.

Have a look at our suggestions below - we're not saying to feed them all - just go with what feels right for your horse. Metabolic health is a sliding scale, influenced by daily choices that compound over time. Each decision - big or small - helps tip the scales in your horse's favour, ensuring lasting wellness and vitality.

1. Think fortify- switch processed feeds to a grass forage-fibre feed, i.e a meadow cob/chaff, and getting as much quality hay going through the hindgut, while closing the nutrient gap with forage-balanced minerals.
2. BiomeTonic , aka the well-known 'oily herbs', stabilise the intestinal environment by protecting the beneficial gut bacteria while creating an unwelcome environment for pathogen microbes and parasites. Some horses seem to need it permanently; others do well when fed every couple of weeks or so. It's very much horses for courses so your horse will no doubt tell you.
3. WildFed adds valuable prebiotic roughage and nutrient diversity to the diet. Either add to the feedbowl or sprinkle a handful over hay every other day or so - horses love to seek out the herbs for enrichment.
4. VitaBoost is more than a supplement - it's a powerhouse of natural nourishment for your horse. Crafted from 9 organic antioxidant-rich ingredients, this soya-free, synthetic-free blend provides essential vitamins in their natural form (A, C, E, K, and B-complex), anti-inflammatory antioxidants, and powerful beta-glucans to fortify vitality, performance, and long-term health. Feed however it suits, either every day or one week a month - whenever you think your horse needs a nutrient boost.
