Informed Sport Certification Explained: What the Logo Actually Means

What the logo is, and why it is on so many tubs

If you shop for informed sport certified supplements in the UK, you will see the same small logo again and again — on protein tubs, pre-workout pouches, capsules and bars. Most shoppers read it as a general seal of approval. It is something much narrower and more specific than that, and knowing exactly what it covers changes how you shop and what you should be willing to pay.

Informed Sport is a certification programme run by LGC, an independent laboratory business, from its testing site at Fordham in Cambridgeshire. It is a commercial programme that brands pay to enter — it is not a government scheme, and it is not a regulator.

What Informed Sport actually certifies

Two things, essentially:

• The finished product batch has been screened in the laboratory against a broad list of substances prohibited in sport, using ultra-trace mass spectrometry.
• The manufacturing site and supply chain have been assessed against the programme's own criteria before certification is granted.

That is the whole scope. LGC is explicit that certification is a risk-reduction programme — no analytical test can prove that something is absent, only that it was not detected at the method's detection limit.

Certification attaches to a batch, not a brand

This is the detail most people miss. A certificate covers a specific batch or lot of a specific product in a specific flavour and size. Two identical-looking tubs on the same shelf can have different batch codes, and only one of them may be listed. That is why every Informed Sport certificate carries a batch number, and why the public database is searchable by it.

It also means a brand certifying one product does not certify its whole range. Plenty of brands run certification on a few lines and not others.

Informed Sport, Informed Choice and Informed Protein compared

LGC runs several programmes and the logos look similar at a glance. They are not interchangeable.

Programme	What is tested	How often	Best suited to
Informed Sport	Finished product, screened against substances prohibited in sport	Every batch before release, plus blind off-the-shelf sampling	Anyone competing in tested sport, where batch-level traceability is the point
Informed Choice	Finished product, same screening approach	Random off-the-shelf retail sampling on a monthly cycle — not every batch	Shoppers who want an independent testing programme without paying for batch-level coverage
Informed Protein	Whether the protein content matches what the label declares	Sampled and analysed for label accuracy	Value-focused buyers comparing cost per gram of protein
No certification	Nothing verified by an independent programme	n/a	Shoppers buying on price, flavour or format alone

LGC also runs Informed Ingredient (for raw material suppliers) and Informed Manufacturer (for production sites). Those logos sit further up the chain and are not the same as a finished-product certificate. Elsewhere you may see NSF Certified for Sport or BSCG marks, which are separate programmes run by separate organisations with their own testing rules.

How to check a certificate before you buy

1. Note the exact product, flavour and size. A 1kg tub and a 2.5kg tub are separate entries.
2. Find the batch or lot number. On tubs it is usually inkjet-printed near the base or on the neck, next to the best-before date. On pouches it is normally on the back seal.
3. Search the programme's public database at informed-sport.com by brand and product. Certified batches are listed individually.
4. If the batch is not listed, it is not covered — even if the packaging carries the logo artwork. Printed packaging often outlives a certification.
5. Check the certificate date. Certifications lapse when a brand stops paying for or stops submitting batches.

If you are buying for tested sport, do this before you open the product, not after. Anti-doping rules place the responsibility on the competitor, not on the manufacturer or the retailer.

What the logo does not tell you

• Nothing about value. It is not a price or quality ranking.
• Nothing about flavour or how easily a powder mixes. Those are down to the formulation and your own preference.
• Nothing about the rest of the range. Check each product individually.
• It is not a substitute for reading the label. You still need to check serving size, servings per container, caffeine in mg where relevant, %NRV figures and the ingredient order — ingredients are listed by descending weight.

Should certification change what you pay?

Certified lines usually sit above equivalent uncertified products on price. Testing every batch has a real cost and it is built into the shelf price. Whether that premium is worth paying depends entirely on whether you compete in tested sport.

Either way, compare on cost per serving rather than tub price:

• Price per serving = pack price ÷ servings per container.
• Price per 25g of protein = (price per serving ÷ grams of protein per serving) × 25. This is the only fair way to compare two protein powders, because scoop sizes differ.
• Watch the serving size. A 30g scoop and a 40g scoop produce very different servings-per-tub figures from the same pack weight.
• Bigger packs and multipacks almost always lower the price per serving — but only buy the large size once you know you like the flavour and will finish it within its shelf life.
• Check the free delivery threshold before splitting one order into two. Consolidating is often cheaper than the saving you were chasing.

Format matters for cost too. Powders are typically the cheapest per serving, capsules cost more but need no scoop, scales or shaker, and ready-to-drink formats carry the biggest premium because you are paying to ship water. For travel and work bags, that premium is sometimes worth it; for daily use at home it rarely is.

Where to look

Certified and uncertified options sit side by side across our range — protein powders, creatine, pre-workout, protein bars and snacks and ready to drink. Filter by brand first if you already know which of a brand's lines are enrolled in the programme.

Practical summary

• Informed Sport certifies a batch of a product, not a brand or a range.
• Informed Sport tests every batch; Informed Choice samples retail stock at random; Informed Protein checks label accuracy on protein content.
• Always verify the batch code in the public database — the logo on the pack is not proof on its own.
• Expect to pay a premium. Pay it if you compete in tested sport; otherwise choose on price, format and flavour.
• Compare on price per serving and price per 25g of protein, never on tub price.
• Buy a small size first, then move to the larger pack or multipack once the flavour is settled.
