What should you look for in informed sport UK?

The programme's anatomy, what it tests and audits, and the strict-liability rule that makes it matter

Informed Sport is a certification programme, and what to look for in it starts with knowing what it actually does, because the logo is easily mistaken for a general quality mark. The programme tests supplement products for substances on the World Anti-Doping Agency's prohibited list, the banned substances an anti-doping test detects, and its distinguishing feature against its sister programme is batch coverage, Informed Sport testing every batch of a certified product before release while Informed Choice, from the same operator, tests at the product level with periodic blind sampling, the every-batch model being the one a competing athlete wants because contamination is a batch event. Alongside the testing, the programme audits the manufacturing site, assessing its controls against cross-contamination from banned substances handled elsewhere in the facility, so certification attests both the product and the process. The reason it matters is the strict liability rule of the anti-doping code: an athlete is responsible for any prohibited substance found in their sample regardless of intent, a contaminated supplement being a documented source of positive tests, and the label, the receipt and the brand's assurances being no defence, so that for anyone subject to testing, at any level where a positive matters, a banned-substance certification on every supplement taken is the only rational policy and the programme's whole reason for existing. Comparable programmes, Informed Choice, BSCG and NSF Certified for Sport, do the same job under different rules, and a sport's own anti-doping body will say which it recognises.

How to verify the logo at source, what the programme does not cover, and the honest note about this site's examples

What to look for on a product is a logo that can be checked rather than trusted, and the programme makes that possible: its public database lists certified products and, for Informed Sport, certified batches, so the athlete finds the product on the database, matches the batch number on the tub to a tested batch, and only then takes it, a logo that does not resolve to a database entry being either a lapsed certification or a misuse, the reputable brands guide's at-source check applied to the one logo where the stakes are a career. Look, too, for the batch number printed clearly on the tub, since the whole model rests on matching it, and for the logo on the product actually being bought rather than on the brand's other products, certification being product-by-product and a brand's flagship being certified while its newer lines are not. What the programme does not cover deserves equal weight, because the logo is not a quality mark in the general sense: it does not test for heavy metals against contaminant limits, the mushroom and botanical categories' central risk; it does not assess efficacy or license any claim, a certified claim-free product staying claim-free; and it does not verify the dose or the form beyond what its own testing incidentally reveals, so a certified product is one an athlete can take without doping risk, and the four label tests, the metals certificate and the register still apply to it as to any tub. The honest note about this site's worked examples, stated as this site states everything about them: the products it prices, the magnesium included, state independent batch testing for metals and UK GMP manufacture and do not carry Informed Sport or any sports certification, so a competing athlete subject to testing applies their sport's rule and chooses certified products for everything they take, this site's method pointing them to the database rather than to its own examples for that decision.

The verdict, a logo checked at source and understood at size

What to look for in Informed Sport: a programme that tests every batch of a certified product for WADA-prohibited substances and audits the manufacturing site, whose logo is verifiable on its public database by product and batch number, the check any athlete subject to strict-liability testing runs before taking anything, and a programme that covers doping risk alone, not heavy metals, efficacy, claims or dose, so that the four label tests and the register still apply to a certified tub. This site's examples, stated plainly: Futuro Labs Magnesium Glycinate, batch tested for lead, mercury, arsenic and cadmium, UK made under GMP, no Informed Sport certification carried, £19.99 for 90 days at 22p a day, which a competing athlete reads as the honest disclosure it is and answers by choosing certified products for everything they take.

What to check on the label

Questions people also ask

What does Informed Sport actually test for?

Substances on the WADA prohibited list, every batch of a certified product before release, alongside an audit of the manufacturing site's contamination controls, the assurance an athlete under strict liability relies on.

What is the difference between Informed Sport and Informed Choice?

Batch coverage: Informed Sport tests every batch, while Informed Choice certifies at the product level with periodic blind sampling, the every-batch model being the one competing athletes want because contamination is a batch event.

How do I check a product is genuinely Informed Sport certified?

On the programme's public database: find the product, match the batch number on your tub to a tested batch, and treat a logo that does not resolve to a database entry as lapsed or misused.

Does Informed Sport certification mean a supplement is high quality?

Only for doping risk: it does not test heavy metals against contaminant limits, assess efficacy, license claims or verify dose and form, so the four label tests, a metals certificate and the register still apply to a certified product.

Are this site's worked examples Informed Sport certified?

No: they state independent batch testing for metals and UK GMP manufacture and carry no sports certification, so a competing athlete subject to testing chooses certified products from the database for everything they take.
