Part of our Zeneara overview. Last checked November 6, 2026.
Zeneara ingredients are seven items in a two-capsule serving: ginkgo 300 mg, taurine 300 mg, a four-strain probiotic blend 300 mg, passion flower 150 mg, valerian 150 mg, zinc 5 mg and vitamin B6 2.4 mg[1]. We read the label image on November 6, 2026.
The sales page tells the story with only part of that list. Passion flower, valerian, L. buchneri and L. hilgardii never appear in it[2].
Zeneara ingredients at a glance
All seven amounts are printed, with only the probiotic strain split hidden, and none of the seven has reliable human evidence for tinnitus. The table puts the label amount next to what the vendor says each ingredient does and how strong the evidence is.
| Ingredient | Amount | Role the vendor claims | Evidence grade |
|---|---|---|---|
| Ginkgo biloba extract (leaf) | 300 mg | Hearing, "boosts GABA" | Weak; NCCIH says not helpful for tinnitus |
| Probiotic blend (L. paracasei, L. buchneri, L. brevis, L. hilgardii) | 300 mg, 30 billion CFU; strain split hidden | Lower glutamate through gut GABA | Weak; no tinnitus trial |
| Taurine | 300 mg | Lower glutamate | Weak for tinnitus; no trial |
| Passion flower powder (stem, leaves, flower) | 150 mg | Not named on the sales page | Limited, for calm and sleep |
| Valerian extract (root) | 150 mg | Not named on the sales page | Weak, for sleep |
| Zinc (as zinc citrate) | 5 mg, 45% DV | Less tinnitus intensity | No tinnitus trial in our evidence |
| Vitamin B6 (as pyridoxal 5'-phosphate) | 2.4 mg, 141% DV | Less tinnitus intensity | No tinnitus trial in our evidence |
Grades follow our evidence cards: "limited" means a few small human trials for some use, "weak" means little or no human data for the use in question.
What is in each ingredient, and what does research say?
Each ingredient below gets the same four checks: what it is, the human trials, the studied dose against the label dose, and a grade.
Ginkgo biloba extract, 300 mg
Ginkgo leaf extract is the best-studied ingredient in the capsule. NCCIH says research suggests it is not helpful for relieving tinnitus symptoms, and three large memory trials were negative[3].
In a 12-week trial of 46 adults with subjective tinnitus, masking level did not change; a questionnaire index of tinnitus handicap fell modestly with ginkgo alone[4]. Most ginkgo studies used 120 to 240 mg a day, so 300 mg is at or above that range. The label omits standardization, so the extract may differ from studied ones. Grade: weak.
Probiotic blend, 300 mg (30 billion CFU)
The blend holds L. paracasei, L. buchneri, L. brevis and L. hilgardii, with no split per strain. Probiotic effects are strain-specific, and the label names species, not strains.
Human L. brevis trials tested named strains for unrelated uses such as influenza, with mostly null results[5]. L. buchneri and L. hilgardii have no human trials at all; buchneri work stops at cell lines[6]. A 2023 paper on gut bacteria and hearing says probiotic effects on tinnitus still need study[7]. The CFU count is promised only at manufacture, not through expiry. Grade: weak.
Taurine, 300 mg
Taurine is an amino acid. Human trials used 1 to 6 g a day for endurance exercise[8] and 3 g a day for blood sugar in type 2 diabetes[9]. The observed safe level is 3 g a day[10].
Zeneara's 300 mg is a tenth of the usual trial dose, and no taurine tinnitus trial appears in the evidence we read. Grade: weak for tinnitus.
Passion flower powder, 150 mg
Passion flower (Passiflora incarnata) is a calming herb. A systematic look at nine trials found most reported less anxiety and no adverse effects[11], and a trial in 110 adults with insomnia measured longer total sleep time on polysomnography[12].
Those studies used extracts, drops or tea. Zeneara uses a powder of stem, leaves and flower, so the doses do not line up. No tinnitus trial. Grade: limited for calm and sleep.
Valerian extract, 150 mg
Valerian root is a sleep herb with inconsistent results. A meta-analysis found people were 1.8 times as likely to report better sleep, with signs of publication bias[13], while an internet-based trial found it no better than placebo[14].
NCCIH describes 300 to 600 mg a day used for up to 6 weeks, and notes the American Academy of Sleep Medicine advised against valerian for chronic insomnia[15]. The label gives no extract ratio. Grade: weak.
Zinc, 5 mg
Zinc citrate at 5 mg is 45% of the Daily Value. Our zinc evidence card lists no tinnitus trial, and 5 mg sits far below the 40 mg adult upper limit set by the NIH Office of Dietary Supplements. Grade: no tinnitus evidence.
Vitamin B6, 2.4 mg
B6 comes as pyridoxal 5'-phosphate, 141% of the Daily Value. The European Food Safety Authority set an adult upper limit of 12 mg a day because of nerve damage at high intakes[16], so 2.4 mg leaves room unless you stack several B6 products. No tinnitus trial in our evidence. Grade: no tinnitus evidence.
How transparent is the Zeneara formula?
The formula is mostly transparent. Every ingredient amount is printed; only the probiotic blend hides how its 300 mg and 30 billion CFU split across four strains[1]. That is a small blend, not a proprietary blend covering the main actives.
Three details are missing from the label: ginkgo standardization (flavone glycosides and terpene lactones), the valerian extract ratio or valerenic acid content, and probiotic potency through expiry. Other ingredients are a hypromellose veggie capsule, microcrystalline cellulose and olive oil.
Third-party sites sometimes copy ingredients from the sales story, which leaves out passion flower and valerian. The label image we read on November 6, 2026 wins over any such list. Label directions: two capsules a day with 6 to 8 oz of water; the sales page says one.
Ingredient safety and interactions
Ginkgo may raise bleeding risk with anticoagulants such as warfarin, and it calls for caution with antiplatelet drugs and before surgery[3]. Valerian should not be combined with alcohol or sedatives such as benzodiazepines and barbiturates[15].
Passion flower can cause drowsiness and dizziness, and zinc interacts with quinolone and tetracycline antibiotics. The label asks anyone pregnant, nursing, under 18 or with a medical condition to check with a physician[1]. The full list, with symptoms to watch for, is on our Zeneara side effects page.
Do these ingredients prove Zeneara works?
No. Studies of single ingredients, mostly at other doses and in people without tinnitus, cannot show what this seven-ingredient capsule does. Ginkgo, the only tinnitus-tested ingredient, showed no reliable benefit, and no trial of Zeneara exists.
We weigh each sales claim against the evidence on does Zeneara work for tinnitus, and what the sound-related promises amount to on Zeneara tinnitus relief. Our method is on the how we check products page.

Frequently asked questions
What is in Zeneara?
Each two-capsule serving has ginkgo 300 mg, taurine 300 mg, a four-strain Lactobacillus blend 300 mg with 30 billion CFU, passion flower 150 mg, valerian 150 mg, zinc 5 mg and vitamin B6 2.4 mg, per the label read November 6, 2026.
Does Zeneara contain valerian?
Yes. The label lists 150 mg valerian root extract and 150 mg passion flower powder per serving, though the sales story never mentions either one. Both can cause drowsiness, so do not combine Zeneara with alcohol or sedative medicines.
Which Zeneara ingredient helps tinnitus?
None has reliable human evidence for tinnitus. Ginkgo is the only one tested in tinnitus trials, and NCCIH says research suggests it is not helpful for relieving tinnitus symptoms. The probiotics, taurine, zinc and B6 have no tinnitus trials in our evidence.
Is Zeneara vegan?
The vendor calls Zeneara vegan and non-GMO, and the label lists a hypromellose veggie capsule with microcrystalline cellulose and olive oil. We did not verify the vegan claim independently, and the probiotic sourcing is not described on the label.
How many Zeneara capsules should you take a day?
The label says two capsules daily with 6 to 8 oz of water, so a 60-capsule bottle lasts 30 days. The sales page says one capsule a day. Follow the label, since every listed amount is per two capsules.
