Reading the label: what to look for on the back of a supplement
The front always looks good. What actually describes a complementary feed is the back label — and there are really only four things to look for there.
Two boxes side by side on a shelf usually look much alike from the front. The difference starts at the back.
1. The amount of each active ingredient
An ingredient list without quantities beside it is just a list of materials. The difference between "contains silymarin" and "80 mg silymarin" is the first sign of how serious a product is. Check, too, whether amounts are given per daily dose or per 100 g — the two produce very different numbers.
2. What the product actually is
The label will carry the words "complementary feed" or an equivalent. That tells you the product is not a veterinary medicinal product and that it accompanies the daily diet. If a box promises something named after a disease, you have a good reason to put it back.
3. Dosage and duration
A good label states the daily amount by bodyweight and the recommended period of use. Those two lines are the clearest evidence that a real usage scenario was considered.
4. Which market it is labelled for
A label is written to the rules of the market where the product may be sold. VetUx London formulas are produced with three compliant labels — UK · EU · TR: one formula, written three times to three sets of regulations. It is a technical detail that decides where a product may legally be sold, and it takes more work than it looks like on the shelf.
What the front does not say
The front tells you what need a product was formulated for. The back tells you how concrete that formulation is. Reading both together is the shortest route to judging a complementary feed.
And one sentence holds in every case: complementary feeds do not replace veterinary examination, diagnosis or treatment. Speak to your vet before adding a product to the routine.
Frequently asked questions
What does "complementary feed" mean?
It is a feed product added alongside the daily diet, not a complete meal in itself. It is not a veterinary medicinal product and makes no such claim.
Does the order of ingredients mean anything?
It is usually listed in descending order of quantity — but the real information is the amount printed next to each active ingredient.
Can I use a product without asking my vet?
Complementary feeds accompany veterinary care, they do not replace it. Especially for an animal already under follow-up, do not add a product to the routine without speaking to your vet.
This article is for general information only; it does not replace veterinary examination, diagnosis or treatment. VetUx London products are complementary feed. If you have any concern about your companion, please consult your veterinary surgeon.
