IngredientsWhat Is in Quiet Tone? Ingredients Listed by Group
Quiet Tone lists twenty-seven names on its panel, in two groups.
Nine vitamins and minerals show a weight and percent Daily Value each. Eighteen plants and amino acids share one 415.5 mg blend line, and three more make up the capsule shell.
Next, see how the formula works.
What is on the panel, what each row is for, and what the one blend figure does and does not allow.
How is the Quiet Tone ingredient list put together?
One panel, two halves, and they are not read the same way.
Two documents share one panel. The first is a vitamin and mineral list of nine rows, each with a weight and a percent Daily Value beside it. The second is a single line reading Proprietary Blend, 415.5 mg, with 18 names stacked underneath it and no weight against any of them.
Reading the bottle means reading those two halves differently. The top half can be checked against a reference intake and against the amounts used in published work. The bottom half can be checked for what is in it and what part of each plant was used, which the label does specify, and for how much room eighteen names have inside one figure.
| The half | Rows | What the label gives you |
|---|---|---|
| Named nutrients | 9 | A milligram or microgram weight and a percent Daily Value on every row, plus the salt form in brackets |
| Proprietary Blend | 1 row, 18 names | One weight, 415.5 mg, covering all of them, plus the binomial and the plant part for each name |
Both halves are reproduced exactly as the artwork prints them on the supplement facts page.
A proprietary blend is legal and common. US labelling rules let a manufacturer declare the total weight of a blend rather than each member, provided the members are listed in descending order of predominance. That last requirement is the useful one, and it is used further down this page.
Which Quiet Tone ingredients carry a printed amount?
Name, weight, Daily Value and the chemical form, which is where the detail is.
Nine, in the order the label sets them out. The third column is the one most lists leave off: the salt or the chemical form, which is printed in brackets on the artwork and decides how much of the weight the body can take up.
| Row, as printed | Per capsule | % DV | What the form means |
|---|---|---|---|
| Thiamin (as Thiamine Mononitrate) | 6 mg | 500% | A stable synthetic form of B1, standard in capsules |
| Riboflavin (Vitamin B2) | 6 mg | 462% | The plain vitamin, the form that turns urine bright yellow at this kind of dose |
| Niacin (as Niacin) | 14 mg NE | 88% | Nicotinic acid rather than nicotinamide; flushing is possible far above this row |
| Vitamin B6 (as Pyridoxine HCl) | 4 mg | 236% | The salt used in nearly every supplement, well inside routine intakes |
| Biotin | 150 mcg | 500% | Plain biotin, and the one row with a consequence outside the bottle |
| Pantothenic Acid (as D-Calcium Pantothenate) | 8 mg | 160% | The calcium salt of B5, which also adds a little of the calcium on the next row |
| Calcium (as Calcium Carbonate) | 12.5 mg | 1% | Chalk. Cheap, alkaline, and needs stomach acid to release the mineral |
| Magnesium (as Magnesium Oxide) | 12.5 mg | 3% | The least absorbable of the common magnesium sources |
| Zinc (as Zinc Oxide) | 12.5 mg | 114% | About 49.9% absorbed in isotope work, against 61.3% for the citrate |
Percent Daily Values are the label’s own figures, based on a 2,000 calorie diet.
Six of those nine are B vitamins or minerals a varied diet already supplies. Their job on a panel like this is coverage rather than effect: they close a gap in someone who has one. That is worth saying plainly because the percentages are eye-catching and 500% of a Daily Value of thiamin is one of the cheapest numbers to put on a label.
Two rows deserve singling out for reasons that have nothing to do with size. Biotin at 150 mcg is five times a Daily Value, and biotin at supplement intakes interferes with the streptavidin chemistry behind many hospital immunoassays; the standing review of that interference and a study covering time-critical analytes both list troponin among the affected tests. Nothing about the capsule is unsafe there; it is simply a row worth mentioning at a blood draw.
And zinc, at 12.5 mg, is the only ingredient anywhere on this bottle that has been tested on its own against ringing in the ears. The Cochrane review of that question pooled three randomised trials in 209 adults and found no evidence of benefit, at very low certainty throughout. That result belongs on an ingredient page rather than buried, and it is revisited in the dosage section below.
What are the eighteen Quiet Tone blend members for?
Sorted by what each plant is studied for, the eighteen fall into four groups.
The blend list reads as eighteen unrelated plants until it is sorted by what each one is studied for. Sorted that way it resolves into four groups, and the shape of those groups tells you more about this formula than any single name does.
Seven traditional calming botanicals
Chamomile, valerian, passion flower, lemon balm, hops, magnolia bark and Chinese skullcap. This is the largest group and the oldest. The generalised anxiety trial of chamomile ran at 1,500 mg a day in three divided doses; the valerian meta-analysis pooled 60 studies and 6,894 people; lemon balm and passion flower both have small controlled work behind them. Hops has never been given alone in this literature at all, appearing only inside a fixed valerian-hops extract.
Three adaptogens and nootropics
Ashwagandha, rhodiola and bacopa. The best-evidenced corner of the blend and the one furthest from hearing. A 2026 dose-response meta-analysis of 22 ashwagandha trials mapped dose against stress scores, a network meta-analysis of 29 bacopa trials placed the working-memory signal at 600 mg a day and above, and the rhodiola work sits in fatigue and stress rather than in the ear.
Four amino acids and neurotransmitter precursors
GABA, L-theanine, L-phenylalanine and 5-HTP. These are the rows a chemist would look at first, because three of the four act on signalling molecules directly. The L-theanine review covers 200 to 400 mg a day; the mood-under-stress study used capsules holding 100 mg of GABA; the most recent controlled 5-HTP trial ran 100 mg a day for twelve weeks. L-phenylalanine is a precursor further upstream and has the thinnest file of the four.
Four that fit none of the above
Lutein, Chinese hawthorn, oat straw and St John’s wort. Lutein is a carotenoid studied in the eye, at 10 mg daily with 2 mg zeaxanthin over five years in AREDS2. Hawthorn’s literature is cardiovascular. Oat straw was given as a single 800 to 1,600 mg dose in acute cognition work. St John’s wort is the outlier that matters most, and it has a section of its own below.
Fifteen of the 18 names sit somewhere on a calm-and-sleep axis. That is a coherent formula, and it is worth knowing which formula you are buying: this bottle is built around rest and stress rather than around the ear. The two vendor scenes on the home page name a shortlist of six between them, which is a sales-page selection rather than the panel.
Why does St John’s wort change how Quiet Tone is used?
Two of the eighteen have a real interaction record, and it is worth stating exactly.
One of the eighteen carries a documented, well-quantified effect on other medicines, and it is the single most useful thing on this page for anyone taking a prescription.
St John’s wort induces the CYP3A4 enzyme and the P-glycoprotein transporter. In practice that means it speeds up the clearance of a long list of drugs, and the two consequences with the strongest published record are specific. Breakthrough bleeding and reduced contraceptive levels are reported with hormonal contraception, and a systematic review gathers those reports in one place. In transplant medicine, ciclosporin levels fall far enough to threaten the graft, which is why transplant teams ask about it by name. The pharmacokinetic work on CYP3A4 induction and the wider interaction data explain the mechanism, and NCCIH keeps a plain-English summary.
Hormonal contraception and transplant immunosuppressants are the two named, documented cases. Anyone taking either should raise this bottle with the prescriber who issued that prescription, by name, rather than treating it as a general caution.
The blend also holds 5-HTP, which raises serotonin availability and therefore overlaps with serotonergic antidepressants; case reports of serotonin syndrome exist for that combination and the 5-HTP review covers the background. Two ingredients out of eighteen, both named on the label, both with a known mechanism. Naming them once and precisely is more useful than a general warning repeated on every section.
What is not on the Quiet Tone ingredient list?
Three well-known category ingredients are missing, and one of those absences is a point in the formula’s favour.
A list is defined as much by what is off it as by what is on it, and in this category the omissions are informative rather than disappointing.
Ginkgo biloba is the most-sold botanical in the tinnitus aisle and it is not here. That is arguably to this formula’s credit: the Cochrane review of ginkgo for tinnitus covered twelve trials and 1,915 participants and found little to no effect on tinnitus handicap. Melatonin is not here either, though melatonin has its own small tinnitus literature. Neither is vitamin B12, N-acetylcysteine, alpha-lipoic acid or any of the other rows that turn up on competing panels.
- The sedative and adaptogen groups are where the money went, not the ear
- No ingredient here duplicates a prescription hearing treatment, because none exists
- The one ingredient with a tinnitus trial attached is zinc, and that trial was negative
- Fifteen of the 18 blend members are calm-and-sleep plants
Set that beside what the professional literature says the category can do. The 2014 AAO-HNS clinical practice guideline recommends against dietary supplements for persistent, bothersome tinnitus, and the 2026 Korean guideline lands in a similar place. A 2026 umbrella review of tinnitus interventions surveys the field. Buying a calm-and-sleep stack with that context in view is a different decision from buying it without, and it is a decision this page would rather a reader made with the context.
How much room is there inside the Quiet Tone blend?
One weight covers eighteen names, so here is every comparison that weight supports.
415.5 mg is the only weight the label gives for eighteen names, so the arithmetic available is arithmetic about the whole row. Two things can be said without estimating a single member.
The first is an average. Split 415.5 mg eighteen equal ways and each member would be about 23 mg. The second is the labelling rule quoted at the top of this page: members of a blend are listed in descending order of predominance. Rhodiola is printed first and 5-HTP last, so the names at the end of the row are smaller than that average, and the names at the start are larger. How much larger is not published, and this desk will not put a figure on it.
| Ingredient, studied alone | The dose its own trial used | The whole blend |
|---|---|---|
| Chamomile | 1,500 mg a day | 415.5 mg |
| Ashwagandha | 600 mg a day | 415.5 mg |
| Bacopa | 600 mg a day and above | 415.5 mg |
| Oat straw | 800–1,600 mg | 415.5 mg |
| L-theanine | 200–400 mg a day | 415.5 mg |
| 5-HTP | 100 mg a day | 415.5 mg |
| GABA | 100 mg | 415.5 mg |
Single-ingredient trial doses, each cited on the supplement facts page and in the sources below.
Three of those seven trial doses exceed the entire blend on their own. That is the comparison the label makes possible, it needs no estimate, and it is the fair way to read a proprietary blend of this size. What it does not mean is that the blend is inert; it means that anyone buying it for a specific plant at a specific studied dose is buying the wrong bottle, and would do better with that single ingredient.
The nine printed rows are the other side of that coin and they are genuinely checkable. Nothing hides. A buyer can compare thiamin at 6 mg or zinc at 12.5 mg against any reference table they like, which is more than most panels in this price bracket allow.
What are the other ingredients in Quiet Tone?
What holds the powder together, and what the shell is made of.
Three, and they are the shell and the machinery rather than the formula: hypromellose (vegetable capsule), magnesium stearate (vegetable), silicon dioxide.
Hypromellose
The capsule itself, made from cellulose rather than gelatin. That single word is why this bottle suits a vegetarian diet, and it is printed on the artwork rather than inferred.
Magnesium stearate (vegetable)
A flow agent, used in fractions of a milligram, that stops powder sticking to the machinery during encapsulation. The vegetable qualifier on the label confirms the source is plant rather than animal.
Silicon dioxide
An anti-caking agent that keeps the powder free-flowing. Both of these turn up on the great majority of capsule panels and neither contributes to the formula.
The label also prints its own storage line, Store in a cool, dry place away from heat and light., and states that it is manufactured in the USA with globally sourced ingredients. Those five printed lines are audited one by one on the label claims page.
Quiet Tone ingredient questions
How many ingredients does Quiet Tone actually contain?
Twenty-seven names in total: 9 nutrients each with a printed weight and percent Daily Value, and 18 plants and amino acids pooled inside one 415.5 mg blend row. Three further ingredients make up the capsule shell and the powder flow agents.
Does Quiet Tone contain ginkgo biloba?
No. Ginkgo is the most familiar botanical in this category and it is not on this panel. The Cochrane review of ginkgo for tinnitus found little to no effect on tinnitus handicap across twelve trials, so its absence is not a gap.
Is the Quiet Tone capsule vegetarian?
The shell is hypromellose, a cellulose material, and the magnesium stearate is labelled vegetable. On the printed evidence the capsule suits a vegetarian diet. The label makes no vegan, kosher or halal certification claim, so those remain unstated rather than confirmed.
Why does Quiet Tone not print the amount of each herb?
Because the 415.5 mg row is declared as a proprietary blend, which US labelling rules permit provided the members appear in descending order of weight. It is a commercial choice rather than an error, and it is why this page compares the blend total against single-ingredient trial doses rather than member by member.
Which Quiet Tone ingredient has been tested against ringing in the ears?
Zinc, and only zinc. Three randomised trials in 209 adults were pooled by Cochrane, which reported no evidence of benefit at very low certainty. None of the other twenty-six names has a tinnitus trial of its own.
Does the Quiet Tone blend contain caffeine or any stimulant?
No caffeine is listed. Rhodiola and L-phenylalanine are sometimes described as activating, but the balance of the blend is sedative: fifteen of its eighteen members sit on a calm-and-sleep axis.
