Most animal supplements have never been near a controlled study. The industry's default evidence is the testimonial — and testimonials, however sincere, cannot separate a product's effect from time, regression to the mean, or an owner's hope. Natural Science Group's position is that animal nutrition deserves the same rigour as human nutrition, and rigour has a specific meaning: controlled, blinded where feasible, measured against outcomes agreed in advance.
What a proper animal supplement trial looks like
The design toolkit comes from clinical research, adapted to veterinary reality:
- A control group. Randomised, placebo-controlled where the setting allows it. Without a control, improvement is a story, not a finding.
- Blinding. Owners, keepers and assessors who don't know which animal received the product — because caregiver placebo effect is real and well documented in veterinary contexts: the animal doesn't know it's being treated, but the person scoring its stiffness does.
- Pre-agreed outcome measures. Validated scoring instruments, activity data, production records, laboratory markers — chosen and fixed before enrolment, so success cannot be redefined after the fact.
- Adequate numbers and duration. Powered and timed to give the question a fair answer, rather than stopping when the data looks flattering.
- Veterinary principal investigators. Every NSG study runs under a veterinary PI with authority over the animals' care — including the authority to withdraw any animal at any time.
Welfare is the protocol's first section
Our trials are feeding and supplementation studies in the animals' own homes, yards and farms — not laboratory experiments. The welfare rules are set out in our Commitment to Animals and apply without exception: nutrition studies in the animal's normal environment, veterinary oversight throughout, no protocol that withholds necessary treatment from any animal, and withdrawal on welfare grounds always available and never penalised. A control group receives its normal complete diet and full veterinary care — the study adds observation, not deprivation.
Trials across our four sectors
Each sector shapes the method differently. Companion studies typically follow owned dogs and cats at home, using validated owner-assessment instruments alongside veterinary examination. Equine work engages yards and riders, with measures suited to work and recovery. Agriculture is in some ways the natural home of the controlled trial: herds and flocks offer meaningful group sizes and production data that is already being measured — feed conversion, yields, cell counts — so an on-farm study can be woven into normal operations. In exotic settings formal trials are rarely appropriate; there, monitored programmes under the institution's veterinary team take their place.
Honesty about results — and about limits
A trial only means something if a null result is a possible outcome, accepted and acted on. When results don't support an effect, the honest responses are to reformulate or to drop the claim — both cheaper, in the end, than marketing a product the data doesn't back. We are equally direct about what supplement trials are not: our products support health and normal function; they are not medicines, and studies of them do not turn them into treatments. Claims stay inside what the category and the evidence allow.
For partners, this capability is available as a service: trial design and management for a white-label or co-developed product, or an independent-minded study of a formulation a partner wants real evidence behind. The credibility that comes back — with vets, buyers and increasingly with regulators — is the point.
Frequently asked questions
Does Natural Science Group test its products in clinical trials?
Where a product's claims warrant it, yes — placebo-controlled studies designed and run with veterinary principal investigators, with outcome measures fixed before enrolment. Trial-backed development is one of our five core capabilities.
Are the trials harmful to the animals involved?
No. Our studies are nutrition studies conducted in the animals' normal homes, yards and farms under veterinary oversight. No animal is denied necessary care, control animals receive their normal complete diet, and the veterinary PI can withdraw any animal at any time. The full welfare rules are published in our Commitment to Animals.
Why does a supplement need a placebo group?
Because caregiver placebo effect is well documented in veterinary settings: owners who expect improvement score improvement. A control group and blinded assessment are the only reliable way to separate the product's effect from expectation and time.
Can a partner commission a trial from NSG?
Yes. We design and manage studies for partners — usually alongside a co-development or white-label programme, when a partner wants genuine evidence behind a product rather than borrowed claims.
Are NSG products veterinary medicines?
No. Our products are nutritional supplements that support health and normal function. They are not medicines, do not treat or prevent disease, and are never a substitute for veterinary care.
