What should you look for in informed sport creatine?

Why a commodity gets certified, the certification check, and the form behind the claim

Creatine is a commodity, a single molecule made at scale by a handful of manufacturers, and it might seem an odd thing to certify, yet it is one of the most certified products on the programme's database, for a reason that is about the buyer rather than the powder: athletes take creatine daily, in a category, sports nutrition, where facilities also handle pre-workouts and other stimulant-bearing products, so cross-contamination risk exists at the site level even where the ingredient itself is clean, and a drug-tested athlete taking a scoop every day for years wants the every-batch assurance the programme provides, which is why what to look for in Informed Sport creatine begins with the certification check done properly. The check: find the batch number on the tub, search the programme's database by product or batch, and confirm that batch appears among the tested batches, the certification being per product and the testing per batch, a logo alone confirming nothing and a lapsed certification or pre-certification old stock being the traps the batch search catches, the athlete then keeping the batch, receipt and a screenshot. The form: creatine monohydrate is the form behind the authorised claim, increased physical performance in successive bursts of short-term high-intensity exercise at 3g a day, and the form with the decades of trials and the examined safety record, so a certified creatine should state monohydrate plainly, the hydrochloride, buffered and ethyl-ester variants carrying marketing rather than the claim's evidence and often a premium, and the dose should be the 3g the claim requires, delivered as a stated serving in a powder or a stated capsule count, with no loading required.

The purity assay certification does not cover, the honest note on this site's shelf, and the creatine card

The check certification does not cover is purity, and creatine has a specific purity question worth knowing: monohydrate manufacture can leave by-products, dicyandiamide and dihydrotriazine among them, at levels that vary with the production process, and the difference between a pharmaceutical-grade creatine and a cheaper one is largely the assay that screens for them, so the buyer who has matched the batch on the programme's database asks the brand the tested brands guide's four questions with creatine's edge, whether the product is assayed for those by-products and for creatine content itself, and where the certificate is, a manufacturing-origin statement from a producer known for pharmaceutical-grade monohydrate being a strong signal and a bare pure creatine claim with no assay being the flash. The honest note, stated as this site states everything about its own shelf: the guides section's worked example is a magnesium, because this site prices no creatine product, and the creatine method above applies to any tub a reader is holding, the buybox on this page being the mineral the guides are measured against rather than a creatine, which is the disclosure the reputable brands guide would demand of anyone else. The creatine card, complete: monohydrate stated, 3g stated as the daily serving, the batch matched on the database for the tested athlete, a purity assay for by-products and content requested from the brand, metals and microbiology as the floor every product carries, pence per day divided against the five-to-ten-pence commodity benchmark so that a certification premium of a few pence is paid knowingly, and the untested lifter reminded that the certification premium insures against a risk they do not carry and that a purity-assayed uncertified monohydrate at the commodity price serves them fully.

The verdict, certified for one thing and assayed for another

What to look for in Informed Sport creatine: the batch on the tub matched on the programme's database, the form stated as monohydrate at a 3g serving behind the authorised claim, and a purity assay for the manufacturing by-products and creatine content requested from the brand, certification covering banned substances and the assay covering purity, two documents for two risks, with the untested lifter served by an assayed uncertified monohydrate at the commodity price. This site's own shelf, disclosed: no creatine product is priced here, the worked example being Futuro Labs Magnesium Glycinate, 300mg elemental at 80% NRV, batch tested, uncertified, £19.99 for 90 days at 22p a day, and the creatine card applying to whichever tub the reader holds.

What to check on the label

Questions people also ask

Why would creatine need Informed Sport certification?

Site-level risk and daily use: creatine is made in facilities that may also handle stimulant-bearing products, and a drug-tested athlete taking it daily for years wants every-batch assurance against cross-contamination.

How do I check a creatine batch is certified?

Find the batch number on the tub, search the programme's database by product or batch, confirm that batch appears among the tested ones, and keep the batch, receipt and a screenshot.

Which form of creatine should a certified product be?

Monohydrate, stated plainly, at a 3g daily serving: the form behind the authorised performance claim and the decades of trials, the hydrochloride, buffered and ester variants carrying marketing rather than the claim's evidence.

Does Informed Sport certification cover creatine purity?

No: it covers prohibited substances and site audit, while purity, the manufacturing by-products dicyandiamide and dihydrotriazine and the creatine content itself, is a separate assay to request from the brand.

Does this site sell or recommend a creatine?

It prices none: the guides' worked example is a magnesium, disclosed as such, and the creatine method here applies to any tub a reader is holding.
