Evidence
Most supplement marketing does not lie about the research. It cites real studies, then draws a conclusion those studies never supported. These pieces are about a gap you can learn to see: the space between what the citation says and what the claim wants you to hear.
Here is the move. Once you have seen it, you will spot it in every aisle.
A real study finds that people with condition X tend to have lower levels of compound Y. That is an association: two things seen together. It does not establish that low Y causes X, that raising Y fixes X, or that swallowing Y raises it in the tissue that matters. A page then cites that study, accurately, beside a bottle containing Y. Nothing false has been printed. The false part happens in your head, which is exactly where no one can be held to account for it.
The second move is quieter. A study is run on 500 mg of an isolated compound. The product contains an undisclosed fraction of that compound inside a nine-ingredient blend. The citation is real. The product it sits next to was never tested. Evidence for an ingredient has been quietly promoted into evidence for a formula.
Neither move requires anyone to lie. Both collapse the moment you ask one question: was this study run on the thing I am about to buy? Usually the answer is no. Knowing that is not cynicism. It is just reading carefully, the way a friend would want you to.

What “linked to” licenses you to conclude, which is less than it sounds.
What “Clinically Studied” Actually Refers To
Almost always true. Almost always irrelevant. Six questions that show why.
Why Evidence for an Ingredient Is Not Evidence for a Formula
A study of 500 mg of one compound says nothing about 50 mg of it in a blend of nine.
