A proprietary blend is a legal way of telling you which ingredients are present while withholding how much of each, and the reason it exists is rarely the reason given.
How they work
US labelling rules permit a manufacturer to group ingredients under a proprietary blend name, disclosing the total weight of the blend and listing the ingredients in descending order by weight, without stating individual amounts. So a blend totalling a gram might be nine hundred and ninety milligrams of the cheapest ingredient and traces of everything else, and the label would be entirely compliant.
What that conceals
Three things. Whether any ingredient is present at a research-relevant amount, which is the practice sometimes called fairy dusting. Whether the expensive-sounding ingredients featured in the marketing are actually present in meaningful quantity. And whether the total dose of any active is safe for you, which matters particularly for pharmacologically active compounds and for anyone stacking multiple products with overlapping ingredients.

See Cognizil PricingThe arguments and the counter
Manufacturers cite formulation protection - preventing competitors from copying a ratio. This has some force for genuinely novel combinations, though ingredient ratios are rarely the hard part of building a supplement and reverse-engineering by laboratory analysis is straightforward for anyone motivated. The countervailing consideration is that the buyer cannot evaluate what they are purchasing or compare it to anything. Whether that trade is acceptable is a judgement, and it is one you are entitled to make by declining.
Key takeaways
- Labels may disclose blend total and ingredient order without individual amounts
- Fairy dusting means including ingredients below research-relevant amounts
- Blends prevent you checking combined doses across overlapping products
- Formulation protection is the stated reason; reverse-engineering is straightforward anyway
Cognizil in context
Nothing on this page is a claim about Cognizil specifically. Cognizil is a dietary supplement providing nutrient support for memory, focus and mental clarity; it is not a treatment for any condition and should not be used as one. For an honest read on whether it is worth the money, our value for money review states both sides. Current Cognizil sale pricing is on the official order page.
