A proprietary blend is a legal way to tell you what is in a product without telling you how much of it.

What the law requires
US labelling rules allow ingredients in a proprietary blend to be listed in descending order by weight with only a combined total disclosed. So a 900mg blend might be 850mg of the cheapest ingredient and trace amounts of the four impressive ones listed after it. Both labels look identical to a shopper.
Why the practice persists
The stated reason is protecting a formulation from competitors. The practical reason is usually cost: it allows a long, impressive ingredient list where the expensive actives are present at doses far below anything studied, and no one can tell.

Note the first ingredient, since it dominates the blend. Compare the blend total against the studied dose of the ingredients listed — if the total is 500mg and three of the actives are studied at 500mg each, the maths is already telling you something. And treat a blend total smaller than one studied dose as a decoration.
What good disclosure looks like
Individually named actives with amounts, as with the five ingredients in SodaSlim, let you evaluate a formula on its merits rather than on trust. That is a meaningfully higher standard than the category norm, and it is worth prioritising when comparing products.
