What Is A Proprietary Blend? How To Read The Quiet Tone Supplement Facts Panel
Quick answer. A proprietary blend is one row on a Supplement Facts panel that gives a single total for several ingredients without splitting it. On Quiet Tone, 415.5 mg covers 18 names listed from the largest share to the smallest. Nine other rows print an amount and a percentage you can check.
- Serving size: 1 capsule. Servings per container: 30.
- Nine rows give an amount, a named form and a % Daily Value.
- The tenth row, Proprietary Blend, prints 415.5 mg and a footnote: Daily Value not established.
- Names under the blend run from the largest share to the smallest. Rhodiola is first and 5-HTP last.
- An even split of 415.5 mg across 18 names would be about 23 mg each. The label does not say it is even.
- The label is not required to split the blend, so nothing here is hidden against a rule. It is simply not published.
How do you read a Supplement Facts panel, step by step?
Most people look at the right-hand column first and miss the rest. Work down the panel in this order instead, and use Quiet Tone as the practice example.
- Find the serving size. For Quiet Tone it is 1 capsule, and a container holds 30. Every amount on the panel is per capsule, not per bottle.
- Read the amount per serving and the named form in brackets. Zinc as zinc oxide is a different product from zinc as another salt, even at the same milligram figure.
- Read the % Daily Value. It is a single reference figure for the whole adult population. It is not a dose or a target. Above 100% means more than the reference figure.
- Look for footnote marks. On Quiet Tone the blend row carries a dagger that stands for Daily Value not established.
- Read the blend names and their order. Order is the one clue to size.
- Last, read the small print under the panel: other ingredients, suggested use, storage and caution.
That sequence takes about two minutes, and it works on any bottle.
What does the Quiet Tone panel say, row by row?
The panel has ten rows. The first nine are tidy and the tenth is the door to the blend.
| Row | Amount | % Daily Value | What to notice |
|---|---|---|---|
| Thiamin (as thiamine mononitrate) | 6 mg | 500% | Water-soluble, so a high percentage is routine |
| Riboflavin (vitamin B2) | 6 mg | 462% | Can turn urine bright yellow. Harmless |
| Niacin (as niacin) | 14 mg NE | 88% | Just under a full day, in niacin equivalents |
| Vitamin B6 (as pyridoxine HCl) | 4 mg | 236% | Also the helper 5-HTP needs to become serotonin |
| Biotin | 150 mcg | 500% | High biotin can affect some lab tests. Tell whoever draws your blood |
| Pantothenic acid (as D-calcium pantothenate) | 8 mg | 160% | Brings a trace of extra calcium |
| Calcium (as calcium carbonate) | 12.5 mg | 1% | A trace, and the label says so itself |
| Magnesium (as magnesium oxide) | 12.5 mg | 3% | A trace, in the form that absorbs least |
| Zinc (as zinc oxide) | 12.5 mg | 114% | A full day. Add up any other zinc you take |
| Proprietary Blend | 415.5 mg | Not established | 18 names, one total, no individual amounts |
Percentages are the label's own arithmetic, reproduced as printed.
Under the table, the other ingredients line reads hypromellose (vegetable capsule), magnesium stearate (vegetable) and silicon dioxide.

What is a proprietary blend?
Think of a recipe card that lists the flour, the sugar and the eggs together and gives only one weight for the whole mixture. A proprietary blend row works the same way. It states a total, then names the ingredients inside it, and it stops there.
The seller's own pages say a proprietary blend is not required to break its total down. That is the plain meaning of the term as it applies here. Why the formulator chose a blend is not published, and we will not guess.
The practical result is that you can read the names and the total, but you cannot read the dose of any single ingredient. You also cannot tell whether a lot of one plant and a pinch of another make up the total. A blend row is not a warning. It records a choice about what to print.
What can you learn from the order of the names?
Names inside a blend run from the largest weight to the smallest. On Quiet Tone that puts Rhodiola crenulata extract first and lutein second, with hops and 5-HTP at the bottom. L-theanine sits thirteenth, below eight botanicals whose own trials used hundreds of milligrams.
That order rules a few things out. A blend that is mostly L-theanine is impossible, for example. It does not tell you the size of any share. In theory the first name could account for most of the 415.5 mg and the last few for almost nothing. We simply cannot tell.
The even-split figure of about 23 mg a name is a useful yardstick for scale, nothing more.
What does Daily Value not established mean?
Many readers see a dagger beside the blend row and take it as a warning. It is not one. It says that no Daily Value exists for a mixture of botanicals, which is true of every botanical on every label. It is a note about the reference figure, not about the amount.
The question the blend row raises is a different one: how much of each thing is in there? The dagger does not answer it.
How can you compare a blend with the dose a study used?
Look up one ingredient, find the dose its published trial used, and set that beside 415.5 mg. This is the fastest test for any blend.
| Ingredient | Dose used in its trial | Compared with the whole 415.5 mg blend |
|---|---|---|
| Chamomile | 1,500 mg a day | More than three times the entire blend |
| Valerian | 530 mg twice daily | A single dose is larger than the entire blend |
| Ashwagandha | 250 mg and 600 mg a day | The higher dose is larger than the entire blend |
| L-theanine | 200 mg a day | About half of the entire blend |
| Oat straw | 430 to 1,290 mg a day | Every tested dose is larger than the entire blend |
| Bacopa | 300 mg a day, primary endpoint missed | About three quarters of the entire blend |
| Lutein | 10 mg a day, for the retina | Blend share not published, and studied in a different organ |
Trial doses are those printed on this website's own pages. None of the trials used this capsule.
Six of those seven single-ingredient doses are bigger on their own than the average share of the whole blend. That is not an accusation. It is just what the arithmetic shows.
What would a better panel look like? Each ingredient would carry its own amount. Each botanical would show an extraction ratio, such as 10:1, and a standardisation marker. With those two details, two products can be compared fairly. This label prints the plant part beside most of the botanical names but neither of the other two details.
Frequently asked questions
What is a proprietary blend?
It is a single row on a Supplement Facts panel that gives one total for several ingredients and does not split it. On Quiet Tone the blend is 415.5 mg and it covers 18 botanicals and amino acids.
What does a proprietary blend mean for dose?
You can read the names and the total but not the dose of any single ingredient. Names run from the largest share to the smallest, which is the only clue about the split.
How do I read a Supplement Facts label?
Check the serving size, then each amount and form, then the percentage of the Daily Value, then any footnotes, then the blend names, and finally the other ingredients and caution lines.
What does the dagger on the Quiet Tone blend row mean?
It means Daily Value not established. That is the usual note for a mixture of botanicals. It is not a warning and it says nothing about how much of each ingredient is present.
Why are some percentages above 100%?
The amount is higher than the reference figure for that nutrient. For water-soluble B vitamins that is routine, because the body clears the excess. Zinc at 114% is the one worth adding to any other zinc you take.
Is there a Quiet Tone supplement without a blend?
Not as published. Nine rows print their own amount. The 18 botanicals and amino acids share one 415.5 mg line, and no individual amounts are published.
Where does this information come from?
The panel rows, the blend order and the label wording come from the printed label artwork. The studies below give the trial doses used in the comparison table.

Our view
A proprietary blend is a legal and common way to print a label. It is neither a trick nor a selling point. It simply limits what you can check. Quiet Tone is honest about the structure: it lists the names, the plant parts and the order. What it leaves out is the one thing that would let you judge the capsule against its own science.
Use the method on this page on any bottle you pick up. If the amounts are printed, check them against the research. If they are pooled, treat the label as a list of names and ask what you can learn from the order and the total. Questions about your own medicines go to a pharmacist. This site is paid for orders, which is why we show you how to check a label for yourself.
