Proprietary Blends: Why Unnamed Ingredients Lower the Score

Do unnamed ingredients lower a supplement's score?

Yes. Among the 91 reviews that record an ingredients line, the 12 that name no ingredient average 4.84 and none is Worth it; the 79 that name them average 5.65.

Our scores come from the sales page and the order form, not from a lab. If a page will not say what is in the bottle, we have nothing to check a claim against, and several of our seven criteria drop at once.

The numbers below are an association inside our catalog, not proof that a missing ingredient list causes a low score. They do show a pattern: the less a page says about what you swallow, the weaker the rest of the offer tends to look. All figures are as of October 2026 and were computed from our own review data.

If you want the scoring rules first, read how the seven criteria work and what the three verdict labels mean.

What is a proprietary blend?

A proprietary blend is a group of ingredients sold under one brand-style name, with a single total amount for the group instead of an amount for each ingredient.

On a real US supplement label, the FDA labeling rule in 21 CFR 101.36(c) says a blend must carry a term such as Proprietary Blend, list the ingredients inside it in descending order of weight, and show the total weight of the blend. You can see which ingredient is biggest, but not how much of each is in a capsule.

That is the label. A sales page is often looser. Some pages in our catalog describe a blend without naming one ingredient, which is a different and weaker situation than a label that names them all and hides only the split.

Nagano Lean Body Tonic is a typical mid case: 12 named ingredients plus a proprietary 8-item antioxidant blend, with no milligram dose for anything. KundaliniFlow is the weak end: the page says only 'proprietary blend of essential ingredients' and gives no names or doses.

What do the catalog numbers show?

Offers with no named ingredient score lower on average, never reach Worth it, and cost more at the cheapest checkout than offers that name theirs.

We split the 91 reviews with an ingredients line into two groups: offers where the line names no ingredient, and offers where it names at least some. Here is how they compare as of October 2026.

Unnamed vs named ingredients (91 reviews)

• No ingredient named (12 reviews): average score 4.84, 0 Worth it, 3 Worth a look, 9 Pass.
• Ingredients named (79 reviews): average score 5.65, 3 Worth it, 47 Worth a look, 29 Pass.
• Scores of 6.5 or higher: 0 of the 12 unnamed offers, 7 of the 79 named offers.
• Median cheapest-checkout price: $95.97 for the unnamed group, $78.99 for the named group.
• The best-scoring unnamed offer is Ikaria Lean Belly Juice at 6.1, still below the 6.5 line.

Which score criteria lose points when ingredients are missing?

Offer clarity, vendor transparency and claim discipline drop the most. Pricing honesty barely moves, so the gap is about information, not about the price tag.

Average subscores on a 10-point scale, unnamed group first: offer clarity 3.88 vs 5.66, value for money 3.29 vs 4.44, vendor transparency 2.83 vs 4.09, claim discipline 3.04 vs 3.99. Pricing honesty is 6.58 vs 6.36 and refund terms 7.96 vs 8.14, so those are not what separates the groups.

The vendor transparency gap is worth a note. Pages that hide the formula often also hide the company: the review of Custom Microbiome Supplement Formula lists no ingredients, no manufacturer and no seller name, and scores 3.4. Hiding the recipe and hiding the maker tend to travel together.

Claims matter too. A page that says a formula 'recalibrates' your gut but never lists what is in it leaves nothing to check, which is why Customizable Microbiome Health Formula gets a 2.0 for claim discipline. Method details are on our methodology page.

What do the unnamed and blend offers look like?

Mostly low scores, with Ikaria the exception at 6.1. The table shows how a few unnamed and blend offers score, with price and billing from each review.

The table mixes both ends: offers that name no ingredient and offers that name them but hide the doses. Score, price and billing come straight from each review.

Does naming the ingredients make a supplement good?

No. A named list is the minimum for a fair review. Of the 79 offers that name ingredients, 52 still note in the same line that doses or amounts are missing.

MindQuell names nine plant ingredients, which beats a hidden blend, yet it scores 4.5 and is a Pass: no doses, four of five cited studies are about melatonin (not on its list), and no company is named.

The opposite case exists too. Vision 20 lists 10 ingredients with no milligram doses and still reaches Worth it at 6.6, because it names a company and a formulator, its price matches the order form and the refund window is 180 days. TitanFlow is similar at 7.0.

So the ingredient list is one input. We never claim that a product works or fails to work; we judge what the offer lets you verify. For wider guidance on health pages see supplement sales page red flags and memory and brain supplements.

What should you check before buying a blend?

Look for named ingredients, a dose for each, a named company and a refund window on the order form. If two of the four are missing, wait or ask a pharmacist or doctor first.

Four-point blend check

1. Are all ingredients named, or does the page only say 'proprietary blend'?
2. Is there a milligram amount per ingredient, or at least a supplement facts panel image?
3. Is a company with an address named, not just a first name or a Digistore24 or ClickBank account?
4. Does the order form show a refund window, and does it match the page? See multi-bottle bundles before choosing a kit size.

None of this is medical advice. If you take medication or have a condition, a doctor or pharmacist can tell you whether an ingredient is suitable for you; a sales page cannot.
