What a proprietary blend actually hides

By The SodaFit USA Review DeskPublished 2026-09-057 min read

Here is a sentence that sounds like disclosure and is not: “Our proprietary blend includes maca root extract, African mango seed extract, grape seed extract…” and on through nineteen names. Every word of it can be true while leaving you unable to answer the only question that decides whether the bottle can do anything.

The two halves of a label, and why only one of them is optional

A United States supplement facts panel has to identify what is in the product. It does not always have to tell you how much of each thing. When ingredients are declared as part of a proprietary blend, the manufacturer can print the total weight of the blend and list its components in descending order, without breaking out an amount for any individual one. That is legal, it is common, and it is not in itself evidence of bad faith.

It is, however, a one-way door for the reader. Names without amounts cannot be reasoned about. Dose is most of what separates an active ingredient from a decorative one, and two formulas with identical ingredient lists can differ by two orders of magnitude in what they contain.

Three tiers of label, and where most products sit

It helps to stop thinking of labels as honest or dishonest and start thinking of them as tiers.

The fully quantified panel prints every ingredient with its amount. You can compare it against the literature, against a competitor, against your own multivitamin. This is the gold standard and it is comparatively rare in the weight-management category.

The named blend prints every ingredient but no individual amounts. You know what you are taking. You do not know how much. This is where SodaFit sits, along with a large share of the category.

The unnamed blend prints a marketing name and little else. If you cannot even get a list, there is no version of due diligence available to you.

What three kinds of label actually discloseOut of 19 ingredients

What actually goes missing

Consider two ingredients from the same formula. Chromium picolinate does its work in micrograms — the adequate intake for adults is in the tens of micrograms a day. L-glutamine appears in ordinary diets in grams. Both occupy exactly one line on a label. Without figures, a serving could be almost entirely one of them, with the other present in an amount that would round to nothing, and the printed list would look identical either way.

This is the part sales pages skip, because the fix is uncomfortable: there is no way to reason around it from outside. You cannot infer amounts from the order of the list beyond “descending”. You cannot infer them from the price. You cannot infer them from the bottle size. Anyone publishing a table of estimated milligrams for a blended product has either obtained figures the manufacturer does not publish — in which case they should say where from — or invented them.

A named blend is better than an unnamed one and worse than a quantified panel. It deserves neither the outrage nor the applause it usually gets.

Why manufacturers do it

Two reasons get given and both are partly true. The first is competitive: a fully quantified panel is a recipe, and a contract manufacturer can reproduce it in a quarter. The second is commercial in a less flattering way: a blend lets a formula carry a long, impressive-sounding list of fashionable ingredients, most of them present in quantities too small to matter. The industry term for that second practice is fairy dusting, and it exists because it works.

You cannot tell from outside which reason applies to any given product. That is the whole problem, and it is why the honest thing for a review site to write is “we do not know” rather than a confident number.

What to do about it as a buyer

Ask. Manufacturer support addresses sometimes answer questions about individual amounts, particularly for anything you need to count — caffeine especially. A refusal is itself informative.

Count what you can. If a formula includes caffeine-bearing botanicals, treat the caffeine as unknown-but-real rather than negligible. Unknown is not the same as zero.

Discount the long tail. When a formula lists nineteen actives and publishes no amounts, the reasonable assumption is that the first few carry most of the weight. Judge it on those, not on the eighteenth name.

Distrust precision you are not owed. If a third-party review page shows you a neat table of milligrams for a blended product, look for the source. If there is not one, you have learned something about the page rather than the product.

The short version

A blend with nineteen printed names tells you the shape of a formula and withholds its scale. That is a genuine limitation rather than a scandal, and the correct response is to hold your estimate of what the product can do a good deal looser than the sales page would like — and to treat any site that fills the gap with invented figures as the less trustworthy of the two.
