| Ingredient | Amount | Pillar / role |
|---|---|---|
| GABA (gamma-aminobutyric acid) | 100 mg | Calm signaling |
| L-Glutamine | 100 mg | Neuro support |
| Grape Seed Extract | 75 mg | Antioxidant defense |
| Green Tea Leaf Extract | 60 mg | Antioxidant defense |
| L-Tryptophan | 50 mg | Calm signaling |
| Panax Ginseng (root) | 50 mg | Circulation support |
Other ingredients: purified water and vegetable glycerin base. Non-GMO, dairy-free, and made without gluten. Amounts reflect the 2026 production formula.
Each ingredient, and why it is here
GABA - 100 mg
GABA is the body's main calming neurotransmitter. In an ear-health context it is included to support the steady, balanced signaling that helps the nervous system feel less reactive to a persistent ring. It is the largest single active in NeuroZen.
L-Glutamine - 100 mg
L-glutamine is the most abundant amino acid in the body and a precursor your system can convert toward GABA and other signaling molecules. It rounds out the calm-signaling pillar and supports the broader amino-acid pool the nervous system draws on.
Grape Seed Extract - 75 mg
Grape seed is rich in proanthocyanidins, antioxidants studied for protecting delicate tissues from oxidative stress. Because cochlear hair cells are so exposed to that stress, grape seed anchors NeuroZen's antioxidant defense.
Green Tea Leaf Extract - 60 mg
Green tea contributes catechin polyphenols, among the best-characterized dietary antioxidants. It works alongside grape seed to help neutralize the reactive byproducts that accumulate in hard-working inner-ear tissue.
L-Tryptophan - 50 mg
L-tryptophan is an essential amino acid and a building block for serotonin, part of the chemistry behind calm, balanced mood and signaling. It supports the same quieting goal as GABA from a different angle.
Panax Ginseng - 50 mg
Panax ginseng has a long history of use for supporting healthy circulation and vitality. In NeuroZen it represents the circulation pillar, helping support the micro-blood-flow the cochlea depends on for oxygen and nutrients.
How we source and standardize
NeuroZen's botanicals are sourced from suppliers who provide certificates of identity and potency, and the extracts are standardized so each batch delivers consistent levels of the active compounds, not just raw plant powder. The amino acids are fermentation-derived and tested for purity. Everything is blended and bottled in a US facility that is FDA-registered and follows current Good Manufacturing Practices (cGMP).
Once a batch is made, a sample goes to an independent, ISO/IEC 17025-accredited laboratory for identity, potency, heavy-metals, and microbial testing before any bottle ships. You can see the current batch's references on the verification page, and the full testing workflow on the quality and testing page.
Who should check with a clinician first?
NeuroZen is intended for healthy adults. If you are pregnant or nursing, under 18, taking prescription medication (especially sedatives, SSRIs, or blood thinners), or managing a health condition, talk with your healthcare provider before starting, since ingredients like L-tryptophan and ginseng can interact with certain medications. NeuroZen is a supplement, not a treatment for any disease.
