What Does Proprietary Blend Mean on a Supplement Label?
A proprietary blend is a group of ingredients listed together under one name, with a total weight for the group. The federal label rule lists blend ingredients in descending order of weight. Flow Nerves is called a proprietary blend by the seller, lists six names, and prints no milligram figure for any of them.

The definition
What does proprietary blend mean?
It means the maker groups ingredients under one name and shows one weight for the group. The rule in 21 CFR 101.36 says a blend appears in the Supplement Facts panel under the term "Proprietary Blend" or another name, with the ingredients inside listed in descending order of weight (21 CFR 101.36, Supplement Facts labels).
The blend carries a total weight. The panel need not give each ingredient its own amount (21 CFR 101.36, Supplement Facts labels). Makers often say this protects a recipe.
What it hides
What can you learn from a blend, and what stays unknown?
You learn the order of the ingredients and the blend total. You do not learn how much of each is in a capsule.
| Question | Listed amounts | Proprietary blend |
|---|---|---|
| Each ingredient's weight | Printed | Not required |
| Total weight | Add them up | Printed |
| Order of ingredients | By the maker | Descending by weight |
| Match to a study dose | Possible | Not possible |
That last row is the main problem. Studies use set doses, so a reader needs amounts to compare.
On this label
Is Flow Nerves a proprietary blend?
The seller's page and the brief call the six names a proprietary blend. We do not have the Supplement Facts panel, so we do not even have a blend total.
The six names are magnesium glycinate, alpha lipoic acid, butcher's broom root extract, L-carnitine, turmeric extract and coenzyme Q10. A U.S. blend panel would show a total weight for them (21 CFR 101.36, Supplement Facts labels). The material we have shows none.
The bars below show amounts studies used, next to a dashed bar for the amount Flow Nerves does not print.
What to do
How do you check a blend before you buy?
Look for the Supplement Facts panel on your own bottle, and ask the seller for each amount in writing.
- Find the words "Proprietary Blend" and the total weight.
- Ask for the milligrams of each name.
- Ask for the maker's name and address. None is printed in our material.
The seller's order desk is +1 (302) 200-3480.
FAQ
Flow Nerves questions people ask
Is a proprietary blend bad?
Not by itself. It just hides each ingredient's weight, so you cannot compare it with a study dose (21 CFR 101.36, Supplement Facts labels).
Why do supplements use proprietary blends?
Makers usually say it protects a recipe. The rule requires only the blend's total weight and the order of its ingredients (21 CFR 101.36, Supplement Facts labels).
Does Flow Nerves print the amount of each ingredient?
No amount is printed in the material we have. Ask the order desk for the milligrams of each of the six names.
Can a blend contain a tiny amount of a named ingredient?
Yes, since only the total is shown. That is why amounts matter when a label cites a study.
