Audifort Ingredients (2026): What’s in It, and What the Evidence Actually Says

What is actually on the label

Audifort is a liquid, not a capsule. The seller’s directions are one full dropper daily — about 15 drops — held under the tongue or stirred into water or juice. The label is described as “over 20 carefully-selected ingredients”, of which six are named publicly:

• Maca root
• Grape seed
• Green tea
• Capsicum annuum
• Gymnema sylvestre
• GABA

No amounts are published for any of them, and the other fourteen-plus are not named. Keep that in mind through everything below, because it is the single biggest problem with this label: without doses, nobody — including your doctor or pharmacist — can tell how much of anything you would actually be taking.

Ingredient by ingredient

Maca root

Evidence in tinnitus or hearing: none found. We could not find a single human study of maca in tinnitus or hearing of any kind.

What it does have is a small body of work on sexual function. A systematic review of four randomised trials in 131 people (Shin and colleagues, BMC Complementary and Alternative Medicine, 2010) found limited evidence of benefit and said outright that the trials were too small and too weak to draw firm conclusions. The same review noted that none of the included trials even attempted to assess side effects.

Grape seed

Evidence in tinnitus or hearing: none found for grape seed extract on its own.

Its real evidence is cardiometabolic. The US National Center for Complementary and Integrative Health summarises it as possibly affecting LDL cholesterol and triglycerides, and possibly lowering diastolic but not systolic blood pressure. Useful, perhaps. Nothing to do with ears.

Green tea

Evidence in tinnitus or hearing: none found in humans. There is animal work on green tea compounds protecting hearing against certain drugs and noise, in rats and guinea pigs. Animal otoprotection studies are a reason to run a human trial, not a reason to believe a supplement works.

Green tea is also the ingredient with the most documented downside — see our side effects and interactions page, because it is a real one.

Capsicum annuum

Evidence in tinnitus or hearing: none found. Capsicum’s human evidence is in pain relief (applied to the skin) and some metabolic effects. Nothing auditory.

Gymnema sylvestre

Evidence in tinnitus or hearing: none found. There is nothing auditory in the literature at all for this plant.

Gymnema’s research is about blood sugar. The NIH’s LiverTox database notes clinical trials showing mild decreases in fasting plasma glucose, while stating that overall effectiveness in treating diabetes has not been shown. That blood-sugar effect matters if you take diabetes medication — again, see the side effects page.

GABA

Evidence in tinnitus or hearing: none found for oral GABA. Worth being precise here, because this is where hearing-supplement marketing usually blurs things: GABA-acting prescription drugs have been trialled in tinnitus. The GABA supplement has not.

What oral GABA does have is a 2020 systematic review in Frontiers in Neuroscience covering 14 placebo-controlled trials, which found limited evidence for stress and very limited evidence for sleep. That same review makes the point the supplement industry tends to skip: there are no data showing that oral GABA crosses the human blood-brain barrier.

The two claims that do not hold up

“Over 20 ingredients”. A long ingredient list is a marketing feature, not a quality one. When a label lists twenty-plus botanicals without doses, the usual reason is that each one is present in a small amount — enough to name, not necessarily enough to do anything. We cannot prove that is the case here, because the doses are not published. That is precisely the problem.

“Absorbs better because it is sublingual”. We found no published human comparison of sublingual versus swallowed delivery for any of these six compounds. Sublingual delivery genuinely works for small, fat-soluble drugs given in tiny doses — nitroglycerin is the classic. Plant extracts like grape seed proanthocyanidins and green tea catechins are large, water-loving molecules normally dosed in hundreds of milligrams, which is not the kind of cargo that crosses under your tongue in thirty seconds. Most of what you hold in your mouth gets swallowed and absorbed the ordinary way.

What the guidelines say about supplements for tinnitus

This is the context every hearing-supplement page should give you and almost none do. The American Academy of Otolaryngology–Head and Neck Surgery Foundation’s clinical practice guideline on tinnitus (Tunkel and colleagues, Otolaryngology–Head and Neck Surgery, 2014) states: “Clinicians should NOT recommend Ginkgo biloba, melatonin, zinc, or other dietary supplements for treating patients with persistent, bothersome tinnitus.”

The two best-studied candidates both failed in Cochrane reviews. Ginkgo biloba: 12 studies, 1,915 participants, and the 2022 review concluded it may have little to no effect. Zinc: 3 trials, 209 adults, and the 2016 review found no evidence that it improves tinnitus symptoms.

Audifort’s ingredients have not been tested in tinnitus at all, so they are not even in that evidence base. Nobody can honestly tell you this formula quiets ringing.

So is it worth trying?

That depends on what you expect for your money. If you want a product proven to reduce tinnitus, no supplement qualifies, and anyone telling you otherwise is selling. If you have already had your ears checked, you have ruled out the treatable causes, and you want to try something with a long refund window, Audifort’s 90-day guarantee is the part of this offer that actually protects you — it is longer than the 30 or 60 days most of this category gives you.

Our position is simple: the formula is unproven, the label is too vague, and the guarantee is what makes trying it a low-risk decision rather than a leap of faith. Judge it at week four to eight, and put day 80 in your calendar so you decide before the window shuts.

Frequently asked

Does Audifort contain caffeine?

Unknown. Green tea extracts range from nearly caffeine-free to substantially caffeinated, and the seller publishes no dose or extract specification. If caffeine late in the day is a problem for you, take it in the morning.

Are the ingredients natural?

They are plant extracts and an amino acid. “Natural” is not a safety claim — green tea extract is natural and is also the most common botanical cause of supplement-related liver injury.

Which ingredient is supposed to do the work?

The seller does not say, and no ingredient in the named six has human evidence in hearing. That is the honest answer.
