How Supplements Get Tested for Quality

Independent testing is the most useful quality signal available to a buyer, and most products described as tested do not offer it.

The standard tests

Identity testing confirms the material is what it claims to be, which for botanicals may involve chromatography, DNA barcoding or microscopy since species substitution is documented. Potency testing quantifies marker compounds, typically by high-performance liquid chromatography or mass spectrometry. Contaminant testing covers heavy metals, microbiological limits, pesticide residues and solvent residues.

Reading a certificate of analysis

A real one names the product and the specific batch, the testing laboratory, the date, the methods used, the specification for each test and the actual results. What often circulates instead is a raw material supplier's certificate for one ingredient rather than the finished product, or a document with no batch number, or one showing only heavy metals and microbiology without potency — which confirms the product is not contaminated while saying nothing about whether it contains what the label claims.

What lab tested actually means

Nothing defined. It does not tell you which laboratory, whether it was independent, what was tested, whether the finished product or only raw materials were tested, or whether results are available. The phrase is compatible with a single in-house test on one ingredient years ago. Ask for the batch-specific certificate for the bottle you will receive — a company doing this properly will send it, and the response itself is informative.

If you are considering Cognicept

Read the Cognicept ingredients page, which sets out both published ingredient lists side by side, and check the guarantee terms. If you take any prescription medication, obtain the supplement facts panel and show it to a pharmacist — the two candidate formulas carry quite different interaction profiles. Our buyer’s checklist sets out twelve checks.
