Do tinnitus supplements work? What the trials actually show

No. No dietary supplement has been shown in good-quality trials to reduce tinnitus. The AAO-HNS tinnitus guideline says clinicians should not recommend ginkgo biloba, melatonin, zinc or other dietary supplements for persistent, bothersome tinnitus ^[1][2]. The 2024 VA/DoD guideline reached the same place: it suggests against ginkgo, dietary or herbal supplements, and nutraceuticals for tinnitus ^[3]. NIDCD's patient page also notes that supplements are not proven to work ^[8].

That can be hard to square with a pharmacy shelf full of "ear ringing" formulas. The gap exists because supplements reach the market without the FDA reviewing whether they work ^[10]. Here is what the research actually shows.

The evidence, supplement by supplement

Supplement	What the trials show	Guideline position	Safety notes
Ginkgo biloba	12 studies, 1,915 people: little to no effect on tinnitus severity or loudness compared with placebo (very low certainty) [4]	Named as not recommended [2]; VA/DoD suggests against [3]	May raise bleeding risk with blood thinners such as warfarin [9]
Zinc	3 trials, 209 adults: no evidence it improves symptoms (very low certainty) [5]	Named as not recommended [2]	Mild effects such as stomach upset in 3 participants [5]
Melatonin	Review of 5 studies: effect on tinnitus can't be confirmed because of study weaknesses; may help tinnitus-related sleep problems [6]	Named as not recommended [2]	Ask your doctor before using it for sleep
Lipo-Flavonoid (with or without manganese)	One trial of 40 people; 12 dropped out; researchers could not conclude it works [7]	Covered by "other dietary supplements" [2]	Trial had no placebo-only group [7]
Other herbal or "hearing support" blends	Evaluated as a group by guideline panels [2][3]	VA/DoD suggests against herbal supplements and nutraceuticals [3]	Ingredients and doses vary by brand

Ginkgo biloba: the most studied, and still no effect

Ginkgo has the most research behind it, and the research is consistently disappointing. The 2022 Cochrane review included 12 studies with 1,915 participants; 11 compared ginkgo with a placebo ^[4].

• Severity: Pooling two studies (85 people), ginkgo users scored 1.35 points lower on a 100-point tinnitus questionnaire, a difference too small to matter and statistically uncertain ^[4].
• Loudness: One study of 73 people found little to no difference from placebo ^[4].
• Bottom line: The review authors wrote that "there is no evidence to suggest that Ginkgo biloba has an effect on tinnitus when compared to placebo" ^[4].

No serious side effects were reported in the four trials that tracked them, but the studies didn't look at interactions with other drugs ^[4]. That gap matters. NCCIH warns that ginkgo may increase bleeding risk in people taking anticoagulants such as warfarin and may interact with other medicines ^[9]. NCCIH also states that research suggests ginkgo is not helpful for tinnitus ^[9].

Zinc and melatonin

Zinc. A Cochrane review found three randomized trials with 209 adults, too different to combine ^[5]. The one trial that used a validated tinnitus questionnaire, in older adults, found no difference between zinc and placebo. One trial that favored zinc used an unvalidated scale and lost more people from its placebo group, which may have skewed the result ^[5]. The conclusion: "no evidence that the use of oral zinc supplementation improves symptoms in adults with tinnitus" ^[5].

Melatonin. A 2015 review found five clinical studies. Their designs ranged from single-group studies to placebo-controlled crossover trials, and all had methodological weaknesses ^[6]. The authors said melatonin's effectiveness for tinnitus could not be confirmed, though it seemed to improve sleep problems linked to tinnitus ^[6].

If tinnitus is wrecking your sleep, tell your doctor. Treating sleep is a reasonable goal on its own; just don't expect melatonin to quiet the ringing.

Lipo-Flavonoid: a small trial, no clear answer

A randomized trial of Lipo-Flavonoid Plus, published in 2016, enrolled 40 people ^[7]:

• One group took manganese plus Lipo-Flavonoid Plus for six months; the comparison group took Lipo-Flavonoid Plus alone ^[7].
• Twelve people dropped out because of side effects or were lost to follow-up ^[7].
• In the manganese group, 1 of 12 improved on questionnaires and another reported less loudness and annoyance. In the comparison group, none of 16 improved on questionnaires; two reported less loudness and one less annoyance ^[7].
• The researchers wrote that they were "not able to conclude that either manganese or Lipoflavonoid Plus is an effective treatment for tinnitus" ^[7].

Because everyone in the trial took Lipo-Flavonoid, it could never show whether the product beats nothing at all ^[7]. The AAO-HNS recommendation against "other dietary supplements" covers it ^[2].

Why the ads sound so convincing

The rules are loose before a product is sold. Under federal law, the FDA does not have authority to approve dietary supplements before they are marketed, for safety or for effectiveness ^[10]. A product marketed to treat, prevent or cure a specific disease is regulated as a drug, and only a drug can legally make that claim ^[10].

Enforcement comes after the fact. In April 2020, the FTC charged marketers of Regenify and Resetigen-D whose ads pitched the products as a treatment for arthritis, tinnitus, asthma and other conditions ^[11]. The FTC said the ads used fake endorsements from medical professionals and consumers ^[11]. The pills were marketed to older Americans through magazine-style mailers and online, with false claims that they were clinically proven ^[12]. The defendants had to pay $1.3 million under a $38.1 million judgment that was partly suspended because they couldn't pay ^[12].

Red flags in a tinnitus supplement ad:

• Promises to cure, stop or "eliminate" ringing. Only a drug can legally claim to treat a disease ^[10].
• "Clinically proven" with no published trial you can look up ^[12].
• Doctor or customer testimonials you can't verify ^[11].
• Mailers designed to look like magazine articles ^[12].

What to do instead

Put the money toward steps with evidence behind them. The AAO-HNS guideline recommends a full hearing test for many people with tinnitus, a hearing aid evaluation if you have hearing loss, and cognitive behavioral therapy for persistent, bothersome tinnitus ^[2]. Our guide to tinnitus treatments with real evidence compares every option side by side, and our guide to what happens at a hearing test explains the first appointment.

Also bring a list of everything you take, including supplements. NIDCD notes that some medicines, especially at high doses, are linked to tinnitus, including NSAIDs, some antibiotics and some antidepressants ^[8]. Don't stop a prescribed drug on your own; ask your doctor.

If you still want to try a supplement

This isn't an endorsement. If you decide to try one anyway, lower the risk:

1. Check interactions first. Tell your doctor or pharmacist, especially if you take a blood thinner and are considering ginkgo ^[9].
2. Measure, don't guess. Score your tinnitus with the same questionnaire, such as the Tinnitus Handicap Inventory or Tinnitus Functional Index, before and after. The VA/DoD guideline suggests these validated questionnaires for monitoring any tinnitus treatment ^[3].
3. Set a stop date and a budget before you start.
4. Don't let it delay a checkup. Tinnitus in one ear or tinnitus that beats with your pulse needs a medical evaluation ^[2]. See our guide to pulsatile tinnitus.
