What should you look for in applied nutrition informed sport?

Three marks on a certified tub: the logo that says enrolled, the lot number that says tested, and the statement that says tested for what, with what each does and does not cover

What should you look for in Applied Nutrition Informed Sport products is a question about a certified range from a large UK sports nutrition manufacturer that makes in its own facility, and the honest answer is a reading order for the tub rather than a verdict on the brand, because a certified product carries three marks that a buyer should find before anything else and each mark says a precise thing. The first mark is the programme's logo, printed on the front or the side, and it says exactly one thing: the product, as listed in the programme's database under its exact name, has been enrolled, its formulation and raw material sourcing reviewed, its manufacturing site audited for banned-substance controls, and its batches submitted for testing. It does not say the tub in hand was tested, and it does not travel to the brand's other ranges, flavours or pack sizes that were not enrolled, so a buyer who finds the logo has found that the product is in the programme and has not yet found anything about the tub. The second mark is the lot number, printed with the best-before date on the base or seam, and it is the only thing that ties the tub in hand to a batch the programme actually tested: the programme's public database lists tested batches by lot number under each enrolled product, a lot number that appears there was sampled and screened, and a lot number that does not belongs to a batch the programme never received, whatever the logo says; a tested athlete looks the lot number up before opening the tub and keeps the record until any testing window has passed, which is the whole of what certification protects. The third mark is the statement of what was tested, which an honest label phrases carefully: the batch was screened for substances on the prohibited list at the laboratory's detection limits, which is what the programme does, and the label does not say that the protein content was assayed, that the heavy metals were checked, or that the product does anything, because the programme does none of those. A buyer who reads the three marks knows that the product is enrolled, that this tub was or was not tested, and that what was tested for was contamination with prohibited substances, and knows that quality, which is a different question, has not been touched.

Three marks, read in a minute, and then the certified tub is a tub like any other, to be judged by the reads that apply to every protein and performance product whether or not it carries a logo, which is the subject of the next section and the part of the review that the logo tends to crowd out.

Four reads on any protein or performance product, certified or not: grams per serving against the threshold, amino spiking, the ingredient list backwards and pence per gram; the brand that makes its own; the worked example; and the verdict

Certification is about contamination and not about quality, so the four reads that judge a protein or a performance product apply to a certified tub exactly as they apply to any other, and a buyer who has read the three marks now turns the tub over. The first read is the grams of protein per serving against the serving weight: a 30g scoop may carry 18g of protein or 25g, the difference being the carbohydrate, fat, sweetener and flavouring that make up the rest, and the high protein nutrition claim requires at least 20 per cent of the product's energy from protein, a threshold most plain whey clears and some flavoured blends do not; the number to carry forward is grams of protein per serving, not serving weight and not the front's percentage. The second read is amino spiking, the documented adulteration in which cheap free amino acids such as glycine or taurine are added to inflate the nitrogen-based protein measurement without adding usable protein: a brand that makes its own product and tests the amino acid profile can say so, and a label that lists free amino acids high in the ingredients paragraph on a product sold as protein is read with that in mind; a tested batch for prohibited substances says nothing about this, which is why the read exists. The third read is the ingredient list read backwards, everything after the protein source: the sweeteners, sucralose, acesulfame K or stevia, the thickeners, the flavourings, the emulsifiers and the colours, each a permitted additive and each a thing a particular buyer may want absent, with the allergens in bold read first by anyone who needs to. The fourth read is pence per gram of protein at the labelled serving, the price divided by the grams of protein in the tub rather than by the tub, which is the number a multi-buy offer cannot disguise and the number that compares a certified whey with an uncertified one honestly, so that a tested athlete can see exactly what the certification premium costs per gram and an untested lifter can see what they are paying for a logo they do not need. The brand in question makes its own products in its own facility, which answers who makes it more plainly than a marketing brand with an unnamed contract manufacturer does and is a point in its favour on the quality question; it does not change the four reads, which are run tub by tub, and a brand that makes its own can still flavour a blend below the protein threshold or sweeten it heavily.

The worked example is not a protein and is read by the same method, with its marks stated honestly: {FL}, 1500mg magnesium bisglycinate stated as 300mg elemental per two capsules against the 375mg reference, which is the mineral's version of the first read; no amino spiking question because it is a single mineral, with a certificate of analysis for the lot number testing lead, mercury, arsenic and cadmium on request, which is the second read's equivalent; an ingredient list that reads backwards as rice flour and an HPMC shell and nothing else, with no sweeteners; and 22p a day at the labelled serving; UK made under GMP and BRC, 180 capsules for £19.99, and not enrolled in any banned-substance programme, which is stated so that a tested athlete treats it as uncertified rather than discovering it. The verdict on what to look for in a certified range from a UK manufacturer that makes its own is three marks and four reads: the logo for enrolment, the lot number in the database for the tub in hand, and the testing statement for what was and was not covered; then grams of protein per serving, a position on amino spiking, the ingredient list backwards and pence per gram, run on the certified tub exactly as on any other, with the tested athlete running the lot number before the seal is broken and the untested lifter asking whether the certification premium per gram buys them anything the four reads do not.

Questions people also ask

Is Applied Nutrition Informed Sport certified?

A large UK sports nutrition manufacturer that makes in its own facility enrols a range of named products in the banned-substance programme, and a certified tub carries three marks a buyer reads in order: the programme's logo, which says the product as listed is enrolled and does not travel to other ranges, flavours or sizes; the lot number, which is looked up in the programme's public database to confirm that the tub in hand belongs to a tested batch; and the testing statement, which says the batch was screened for prohibited substances and does not say anything about protein content, metals or effect; the reader confirms the product and the lot in the database rather than taking a logo's word.

What does the Informed Sport logo on a protein tub actually tell me?

One precise thing: that the product, under its exact listed name, has been enrolled in the programme, with its formulation and raw material sourcing reviewed, its manufacturing site audited for banned-substance controls and its batches submitted for screening against the prohibited list; it does not tell a buyer that the tub in hand was tested, which only the lot number in the public database does, it does not cover the brand's uncertified ranges, flavours or pack sizes, and it says nothing about the protein content, the amino acid profile, the heavy metals or the sweeteners, which are the four reads a buyer runs on any protein with or without the logo.

How do I check the protein content on a certified whey?

By the first of the four reads that apply to any protein, certified or not: the grams of protein per serving in the nutrition table, read against the serving weight, since a 30g scoop may carry 18g or 25g of protein with the rest made up of carbohydrate, fat, sweetener and flavouring, and against the high protein nutrition claim's threshold of at least 20 per cent of energy from protein, which plain whey clears and some flavoured blends do not; the number carried forward is grams of protein per serving, and the certification's prohibited-substance screen does not assay it.

What is amino spiking and does certification prevent it?

Amino spiking is the documented adulteration in which cheap free amino acids such as glycine or taurine are added to a protein powder to inflate the nitrogen-based protein measurement without adding usable protein, and certification does not prevent it, because the banned-substance programme screens a batch for prohibited substances and does not assay the amino acid profile; a brand that makes its own product and tests the profile can say so on request, and a label listing free amino acids high in the ingredients paragraph on a product sold as protein is read with the practice in mind.

Is a certified protein worth the extra cost?

For a tested athlete, or anyone who might become one, yes without question, since under strict liability the lot number in the database is the only protection against a contaminated batch and the premium per gram of protein is the cheapest insurance in sport; for a lifter who will never be tested, the four reads decide the tub and the logo adds nothing to them, so the premium is read as pence per gram of protein against an uncertified whey that passes the same four reads, and paid only if the certified tub is also the better product on grams per serving, amino spiking, the ingredient list and price.
