2 ingredients

Beta-Glucan

Immunity

A soluble fibre found in oats, barley, baker's yeast and mushroom cell walls. The oat and yeast forms differ in structure and do different things.

What it does in the body

Oat beta-glucan forms a viscous gel that traps bile acids in the gut, forcing the liver to draw cholesterol from the blood to replace them. Yeast beta-glucan is recognised by receptors on immune cells instead.

What the research looks at

  • LDL cholesterol from oat beta-glucan
  • Frequency of upper respiratory infections
  • Post-meal blood glucose
Typical daily dose
3 g oat, 250–500 mg yeast
Time to effect
4–12 weeks
Usually taken
With meals

Inulin (Prebiotic Fibre)

Fibre

A chain of fructose units found in chicory root, Jerusalem artichoke and onion. It is a prebiotic: food for bacteria rather than bacteria themselves.

What it does in the body

Human enzymes cannot break the bonds in inulin, so it reaches the colon intact and is fermented by bifidobacteria into short-chain fatty acids, primarily butyrate, which the colon cells use as fuel.

What the research looks at

  • Bifidobacteria counts in stool
  • Calcium absorption
  • Post-meal glucose and satiety
Typical daily dose
5–10 g
Time to effect
2–4 weeks
Usually taken
With food, increasing gradually

Why the form and the dose matter

Two products can name the same ingredient on the label and behave completely differently. Magnesium oxide and magnesium glycinate are both magnesium; only one of them is absorbed properly. Ethyl ester fish oil and triglyceride fish oil are both omega-3. Folic acid and methylfolate are both folate, but not for everyone.

That is the difference this page is written to make visible. Where a form matters we have given it its own entry rather than hiding it inside a general one, and the dose listed is the one used in the research — not the smallest amount a manufacturer can put on a label and still name the ingredient.

We only describe a product as third-party tested when there is documentation behind the claim. Below is what each of our brands actually documents, brand by brand.

Third-party testing

Certificates of analysis

Pick a brand to see what is actually tested and who tests it. Four of the seven publish reports you can open right here — and they publish different amounts, from a certificate for every batch down to a single lot. The other three document their testing and hand over the paperwork for a specific batch when you ask. That difference is worth knowing before you buy, so we have not smoothed it over. Every report is also linked from the product it covers.

Blueprint 24 reports published

Every batch goes to an independent accredited laboratory in the United States, which checks the contents against the label and screens for heavy metals, microbes and other contamination. Blueprint publishes the full report for every batch, and a new one follows each production run.

Supplements

Nutrition

Skincare

Haircare

Lineage Provisions 9 reports published

Samples from every batch are run on ICP-MS, LC-MS and GC-MS and screened for more than three hundred contaminants, among them heavy metals, glyphosate, pesticides and mycotoxins. The analyses are done by Light Labs, who publish a running report per product with every test result in it — not a single certificate but the whole series, with the date of the most recent test.

Supplements

Nutrition

Designs for Health 14 reports published

Raw materials are tested for identity, purity and potency at external ISO-certified laboratories and screened for heavy metals, pesticides and microbiological contamination. A supplier’s own certificate is treated as a claim to verify rather than a result to accept. Certificates are published per lot rather than for the product as a whole, so the one below covers the lot number printed on it and no other — for a different lot, ask us and we will request it.

Supplements

SALTE 1 report published

Each batch is sent to Eurofins, an independent accredited laboratory, which confirms that the sodium, potassium, magnesium and chloride in a sachet match the amounts on the packet. The published report covers five flavours in one document and is the laboratory’s own, in Swedish.

Supplements

ARMRA Testing documented

Every production run is audited by ISO/IEC-accredited third-party laboratories for heavy metals, glyphosate, other contaminants and microbiology before any of it is released for sale. ARMRA documents the programme and its certifications publicly; the report for a specific batch comes from the manufacturer on request.

Quicksilver Scientific Testing documented

Made in an NSF/ANSI 455-2 GMP-certified facility in Colorado with its own ISO/IEC 17025-accredited testing laboratory. Every batch is tested both in-house and by outside laboratories for potency and purity; the certificate for a batch comes from the manufacturer on request.

Solgar Reports on request

Solgar tests raw materials on arrival and finished products before release in its own quality laboratory, and manufactures to GMP. That is an in-house programme, not an outside verification: Solgar carries no NSF or USP certification, so we do not describe it as third-party tested. Batch documentation is available from the manufacturer on request.

Vital Nutrients Testing documented

Vital Nutrients documents a Quality Assurance Programme that engages third-party laboratories — every batch of GMO-susceptible ingredients, for example, is tested for GMO markers at an independent genetics laboratory, and even the bottles are third-party verified BPA-free. Individual lot certificates are not published; documentation for a batch comes from the manufacturer on request.

T.A. Sciences Testing documented

T.A. Sciences documents an end-to-end testing and analysis programme across sourcing, formulation and US manufacturing, and TA-65 has been determined Generally Recognized as Safe (GRAS) by an independent expert panel. That safety assessment is not batch testing, and no lot certificates are published — documentation comes from the manufacturer on request.

Why testing matters

Why does a supplement need testing at all?

Because nothing else verifies the label. A supplement is regulated as a food, not as a medicine, which means no authority checks each batch before it reaches a shelf. Testing is what turns the number on the tub into something you can look up.

What is being tested for?

Two separate things. Identity and quantity — is the ingredient present, and in the amount the label states. And contamination — heavy metals, microbes, solvent residues and traces from the packaging, which can come from the raw material, the production line or the container.

How often is the label actually wrong?

Often enough to be worth checking. Of 272 supplements implicated in liver injury in the United States, 51 per cent had contents that did not match the label (Hepatology Communications, 2019). Among 57 botanical sports supplements, 89 per cent were inaccurately labelled and 40 per cent contained none of the labelled ingredient at all (JAMA Network Open, 2023).

What can I ask you for?

The report for the batch you were sent. Where a manufacturer does not publish one, we ask them for it — tell us the product and the batch number on the tub and we will come back with what they give us, or with the fact that they would not.

The certificates are the property of the manufacturers and their laboratories, and are linked here in their original location. Blueprint’s reports may not be reused without Blueprint’s permission.

They do not replace a varied diet, sleep, movement or medical care. Doses and timings are those used in published research and on product labels; they are not a recommendation.
