Grow the same fruit in two places and you get two different chemical profiles. Soil, weather, ripeness at harvest and time in storage all move the numbers. That variation is fine in a fruit bowl. It is a problem the moment you want every batch of something to be the same as the last one.
Standardisation is a promise about consistency
To standardise an extract is to define one or more marker compounds, measure them in every batch, and adjust the process until each batch lands within a stated range. The label figure is not a marketing round-up — it is the specification the batch had to meet to be released.
“Standardised” is a claim about sameness. It is not, by itself, a claim about effect.
That distinction matters and is often blurred. Knowing an extract contains a consistent amount of a marker compound tells you the material is reproducible. What that material does in a person is a separate question, answered — if at all — by research on that material, at that dose, in people.
What to look for
A specific named compound rather than a vague category. A quantity with a unit. The part of the plant used, since different parts have different chemistry. And an extract ratio or a defined method, so the number has a process behind it.
