Is a certification mark on a pack enough?
Answer
No. A logo is a claim about a product line at the time the artwork was printed. The check is the batch number, looked up against the programme's published result.
Key takeaways
- Is a logo enough?
- No. Artwork outlives certifications, formulations change and manufacturing sites change.
- What is the check?
- The batch number on your tub, searched against the programme's listing.
- What if nothing comes up?
- Treat the product as unverified rather than as proof of a problem.
Why the logo is not the check
Packaging is printed in advance and used until it runs out. A certification can lapse, a formulation can change, or production can move, and the artwork carries on saying what it said when it was designed.
None of that is necessarily dishonest. It means the logo describes a product line at a point in time and the batch number describes the tub in your hand, and under strict liability only the second one matters.
The check itself
Find the batch number, usually stamped on the base or the side alongside a best before date. Search it in the certification programme's published listing. A brand or product hit is not enough on its own.
Photograph the number when you open a tub, because ink stamps rub off and the packaging gets thrown away. Searching for Futuro Labs Magnesium Glycinate will return nothing, because none of the four products on this site is certified by any programme.

Questions players ask
Is a certification logo enough?
No. It describes a product line at the time the artwork was printed.
What should I search?
The batch number from your tub, not the brand or product name.
Should I keep the packaging?
Yes, for as long as you are taking the product.
Why do formulations change without the artwork?
Packaging is printed in advance and used until it runs out.
Does a brand hit count?
No. A brand or product hit is not the same as your batch being screened.
What if the tub has no batch number?
That is unusual and worth querying. It is the reference everything else depends on.
