Structure-function claims: A Practical Guide

Getting the basics right

Before anything else, it is worth pinning down exactly what is being discussed. Structure-function claims is the specific category of claim supplements are permitted to make. In the context of memory, cognition and nootropic supplements it functions as the legal boundary that shapes every word on a supplement label, which is why it appears so often on labels and in the copy that surrounds them.

With that established, the useful question is what the evidence actually supports. On the evidence, the position is that Structure-function claims has clearly defined in regulation, and routinely stretched in marketing. That is a more specific statement than either “clinically proven” or “no evidence”, and the specificity is the point — it tells you how much weight the claim will bear before it breaks.

The details most people miss

The honest summary of the evidence is this:

• Supports, helps maintain and promotes are permitted structure-function verbs.
• Supports memory is permitted; prevents memory loss is not.
• Treats, cures, prevents and reverses are drug claims and are prohibited.
• The required disclaimer must accompany structure-function claims.

Those points are not equally weighted, and it is worth noticing which do the real work. The detail that supports, helps maintain and promotes are permitted structure-function verbs is the sort of thing that changes how you read every subsequent claim, because it sets the scale. General background on this area is available from FTC health products compliance guidance, which is a better starting point than any brand page.

Common mistakes worth avoiding

This is the part that belongs in bold rather than in small print. The gap between what a label claims and what its surrounding marketing implies is where buyers are most reliably misled. That is not a reason to avoid the subject; it is a reason to treat it with the specificity it deserves rather than as a slogan.

A second point belongs here too. The surrounding marketing often implies what the label cannot state. Taken together with the caution above, that is usually enough to separate a claim worth acting on from one worth noting and moving past. NCCIH on Ginkgo covers the wider regulatory and clinical background if you want to go further.

Putting it into a routine

Here is the version you can act on. Read the exact verb in any claim, because the verb tells you which category the product is in. It is a small change, and small changes you actually make outperform elaborate ones you do not.

When this appears on a supplement label rather than in a study, the questions shift slightly. You want the amount, the standardisation where a botanical is involved, and confirmation that the research being cited measured the outcome the product is sold for — memory, rather than mood or a marker in a dish. Where any of those is missing, the honest conclusion is that you cannot evaluate it, which is different from concluding it does not work.

One thing worth repeating on any page in this category: this formula contains St. John’s Wort, which lowers the blood levels of a long list of prescription medicines. And if memory difficulty is persistent or worsening, that is an appointment rather than a purchase — several common causes are treatable.

The Memodyne official website reference publishes the full ingredient list, including the one active with no cognitive evidence at all. If you want the applied version, see what the product actually is.

None of this makes the subject unimportant. It makes it ordinary, which is more useful to know than either the enthusiastic or the dismissive version.
