CogniZil's label uses a proprietary blend format — 19 named botanicals and amino acids sharing one combined 15.47mg weight. Here's what that structure does and doesn't tell you.
You get the full ingredient list, in descending order by weight, and a combined total. That's more transparent than an undisclosed formula with no ingredient list at all.
You don't get the individual amount of any single ingredient. Nineteen ingredients sharing 15.47mg could mean a meaningful dose of the first-listed ingredient and trace amounts of the last — the label alone can't tell you which.
Published research on an ingredient like guarana or ginseng is almost always done at a specific, stated dose. Without knowing how much of that ingredient sits inside a shared 15.47mg blend, you can't confirm whether this formula's amount is anywhere close to research-backed levels.
A named, ordered ingredient list beats an unlisted blend, but it still falls short of individual per-ingredient doses. Know which one you're looking at before comparing claims to research.
