Proprietary Blend on a Label: What It Hides and Shows
A proprietary blend is a group of ingredients listed under one total weight, without the amount of each. U.S. labeling rules allow this if the ingredients are listed in order from most to least by weight (21 CFR 101.36 (eCFR)). The SciatiEase herb blend is 50 mg in total, so each herb is at most a share of that.

What is a proprietary blend on a supplement label?
A proprietary blend is a set of ingredients shown with one combined weight. The rule lets a maker keep the single amounts private (21 CFR 101.36 (eCFR)).
The ingredients must still be listed in descending order by weight. The one with the most comes first.
The maker may also use another descriptive name for the group. SciatiEase labels its group "Proprietary Blend" and prints 50 mg for the lot.

How much of each herb is in the SciatiEase blend?
We cannot say how much of each herb is in the blend. We can bound it. If herb number k is listed kth by weight, it can hold at most 50 divided by k mg.
That gives feverfew at most 50 mg, passionflower 25 mg, Chinese skullcap 16.7 mg and oat straw 12.5 mg. These are ceilings. The real amounts are lower, because the four must add up to 50 mg.
All four are 4:1 extracts, so each milligram stands for more raw plant. That does not tell us the active dose. Our herbal blend page covers each herb.
Studies use set doses. With hidden amounts, you cannot compare the blend with any study dose.
Why do makers use proprietary blends?
Makers use blends to protect a recipe and to keep labels short. Some also use them to hide that an ingredient is present in a very small amount.
A blend is not wrong by itself. It becomes a problem when the label gives a long ingredient list with a small total weight. Then the headline herbs may be present only in tiny amounts.
The SciatiEase blend is small next to its other lines. It is 50 mg, while the AlphaPalm Blend is 750 mg and shows both amounts. Judge the product on the lines that give amounts, and treat the herbs as a minor part.
- Compare the blend total with the other lines.
- Count how many ingredients share the total.
- Ask the maker for the single amounts.

FAQ01
Quick answers on proprietary blends
Is a proprietary blend legal?
Yes. U.S. labeling rules allow a blend to show only its total weight, with ingredients listed from most to least by weight (21 CFR 101.36 (eCFR)). Legal does not mean the amounts are known, so ask the maker for them.
Does the first herb in a blend have the most?
Yes. Ingredients in a blend must be listed in descending order by weight, so the first has the most. It does not tell you how much more. The first herb can be a little more than the second.
Can I compare a blend with a study dose?
Not directly. With single amounts hidden, you only know a ceiling for each herb. A study dose is a fixed amount, so the match cannot be confirmed from the label alone.
