Some partnerships are a logo exchange. This one is a laboratory commitment: every horse at Horses Smith — from growing foals on proven damlines to competition horses in full international work — will be fed on individually designed liquid formulations, developed by NSG's formulation practice, and adjusted as each horse's season, workload and growth stage change.

What the partnership involves
Horses Smith runs on a principle we recognise: every horse is on a plan. Our job is the nutritional layer of that plan, and it works the way our equine practice always has — evidence first, then formulation, then adjustment against the animal in front of us:
- Bespoke, not off-the-shelf. These are not products pulled from a range; each formulation is designed for a named horse against its age, bodyweight, workload and breeding status.
- Smart-dosed liquids. Liquid formats are what make true individual dosing practical: titrated precisely to the horse, absorbed consistently, and adjustable week by week without rebuilding the feed room. A tub of powder is a product; a smart-dosed liquid is a programme.
- Human-nutraceutical standards throughout. The same peer-reviewed actives library, claim discipline and UK GMP manufacturing that stand behind everything NSG makes — with development running in association with Supplement Factory, whose laboratories and manufacturing sit behind the formulations.
- Documentation that travels. When a horse leaves the yard, its nutrition history goes with it — what it was fed, why, and the formulation it is currently on — so a buyer inherits a programme, not a guess.
In their words
"It is a privilege for me to have access to Lisa and her team. The knowledge and love for animal welfare at NSG has always been an interest to me over the three years I have known Lisa. She has helped thousands of animals have a better life, and I am thrilled she will now apply her skills to Horses Smith."
Harriet Smith — Founder, Horses Smith
"Natural Science Group is the fastest evolving business I have ever been involved with, because people are taking care of their animals better than ever before. As we humans have understood the value of nutrition, this has passed on to our loved furry friends. Now NSG is intelligent-dosing animals the same way our colleagues do for humans, maybe better in some cases. Harriet is at the cutting edge of breeding. I am not surprised she approached me for this partnership. We are going to make a great team."
Lisa Hilton — Co-founder, Natural Science Group
A note on transparency
This partnership is closer to home than most, and we'd rather say so plainly, as Horses Smith did in their own announcement: NSG co-founder Lee Smith has long stood behind the nutrition programme at the Horses Smith yard, and this partnership formalises that work with the group's full product-development engine behind it. We think the connection is a strength — nobody designs a feeding programme more carefully than for the horses they know by name — but it is a connection, and you should hear it from us.
What it means beyond one yard
Bespoke, individual-animal formulation is the sharpest version of what NSG does for every partner: the same discipline, scaled from one named horse to a practice's client base or a producer's herd. If the Horses Smith model — individual formulation, honest documentation, adjustment against the animal — is what your yard, practice or brand needs, that conversation starts with an enquiry marked Equine.
Frequently asked questions
What is the Natural Science Group–Horses Smith partnership?
NSG is Supplement Product Development partner to Horses Smith, Harriet Smith's breeding and showjumping yard — designing bespoke, smart-dosed liquid formulations tailored to each individual horse in the collection, developed to human-nutraceutical standards and adjusted as each horse changes.
What is smart-dosing in equine nutrition?
Dosing active ingredients to the individual horse — its bodyweight, workload, growth stage and season — rather than feeding a standard scoop, and adjusting over time. Liquid formulations make that precision practical.
Can other yards or businesses get bespoke formulation from NSG?
Yes — individual and bespoke formulation sits within NSG's partnership programmes for yards, veterinary practices, brands and producers. Conversations start via our enquiry form.
