"Formulated from peer-reviewed actives" is easy to say and rarely explained. This library is the explanation. Each page below covers one active ingredient we work with: what it is, the state of the evidence in animals, the species and product categories it's used in, and how we approach dosing and formulation. We keep the language honest — where the research is strong we say so, and where it's thinner than the marketing around it, we say that too.
Joint and mobility
- Collagen (undenatured type II and hydrolysed) — the modern centre of gravity in joint formulations for dogs and horses.
- Glucosamine — the most familiar joint active in companion and equine nutrition.
- Chondroitin sulphate — glucosamine's long-standing partner in cartilage support.
- Hyaluronic acid — the joint-fluid molecule itself, fed orally in modern combinations.
- MSM (methylsulfonylmethane) — an organic sulphur source used across joint and comfort formulations.
- Green-lipped mussel — a whole-food marine active with a growing canine evidence base.
- Boswellia serrata — a botanical resin extract used in joint comfort blends.
- Turmeric and curcumin — widely used, widely misunderstood; formulation determines whether it does anything.
Skin, coat and condition
- Omega-3 fatty acids (EPA and DHA) — among the best-evidenced nutrients in veterinary nutrition, spanning skin, joint and cognitive support.
- Vitamin E — the workhorse antioxidant, particularly important alongside high oil intakes.
- Zinc — a trace element central to skin integrity, hoof and horn quality, and immune function.
- Biotin — the best-known active for hoof horn quality in horses.
Digestive and gut health
- Probiotics — live micro-organisms used to support digestive balance in companion animals and livestock.
- Prebiotics — the fibres that feed a beneficial gut microbiota.
- Postbiotics — inanimate micro-organisms and their fermentation products; gut support without the fragility of live organisms.
- Live yeast (Saccharomyces cerevisiae) — a rumen-function staple in dairy and beef nutrition.
Calm, behaviour and recovery
- L-theanine — an amino acid studied for calm support in dogs and cats.
- L-tryptophan — the serotonin precursor used in equine and companion calming formulations.
- Magnesium — a mineral with genuine roles in muscle and nerve function, and a calming reputation that needs careful framing.
Performance and recovery
- Electrolytes — replacing what sweat, heat and work take out, in horses above all.
- Taurine — the amino acid cats cannot live without, with a supporting role in heart-focused formulations.
Trace and skeletal nutrition
- Selenium — essential, deficiency-prone on some UK ground, and dose-critical.
- Copper — essential and interaction-driven in cattle and horses; dangerous in excess to sheep.
- Calcium & vitamin D3 — the skeletal partnership that defines reptile husbandry and eggshell quality alike.
This is the full documented library — twenty-four actives across joint, skin, gut, calming, performance and trace nutrition — and it grows as the evidence does. If you're a partner and want to talk through an active that isn't listed — or challenge one that is — start a conversation.
