Pick up almost any supplement and you will eventually find a line naming something like a "Advanced Respiratory Complex" with a single total in milligrams beside it, followed by a list of ingredients and no individual amounts. That is a proprietary blend, it is entirely legal, and it conceals the only number that determines whether the product can work.
What is being hidden
US labelling rules require that ingredients in a blend be listed in descending order by weight, and that the total weight be declared. They do not require individual amounts. So a 900 mg blend listing six botanicals tells you the first one weighs the most and nothing else.
In practice that allows a formula to be 880 mg of a cheap filler ingredient and 20 mg split across five impressive-sounding botanicals — a technique known in the trade as fairy dusting. The label is accurate. It is also useless for the one judgement you are trying to make.
The usual justification, and why it is thin
Sellers say blends protect a formula from being copied by competitors. Exact ratios genuinely are commercial information.
The problem is that it is not the only option. Plenty of companies disclose every amount and compete perfectly well, because the actual moats in this industry are brand, sourcing relationships and manufacturing quality, not a ratio any competent lab could reverse-engineer from a bottle in a week. Secrecy protects the seller from comparison far more than it protects the formula from copying.
Other label moves worth recognising
- Per-serving versus per-bottle sleight of hand. Check how many capsules or pumps constitute a serving. An impressive number may require four capsules, which halves the days your bottle actually covers.
- Extract ratios without standardisation. "10:1 extract" tells you about concentration, not about the active compound content. Standardised to a named marker percentage is a more meaningful statement.
- Latin names doing the persuading. Impressive botanical nomenclature is not evidence. Look up the plant, not the italics.
- "Clinically studied ingredients." Note the phrasing. The ingredient has been studied — at some dose, in some population, possibly finding nothing. It does not mean this product at this dose was studied.
- FDA-registered presented as FDA-approved. No supplement is FDA-approved. A facility can be registered, which means it is on a list and inspectable. Real, but a far smaller claim than it is usually made to sound.
How to read a label in two minutes
Turn it over and look for individual amounts on every active. If they are there, pick the one ingredient the marketing leans on hardest, search for its research, find the dose used, and compare. That single comparison tells you more than the entire front of the package.
Then check the other ingredients section, which is where the carriers, fillers and preservatives live. A short list you can read is a good sign. And finally, look for whether the seller acknowledges any limitation at all — every botanical has gaps in its evidence, and a page presenting unbroken certainty has decided not to mention them.
Why short lists have an advantage
Not because fewer ingredients are inherently better, but because a short list is checkable. Three named actives can be researched individually in ten minutes. Eighteen ingredients inside two proprietary blends cannot be evaluated at all, by anyone, including the person selling it to you.
