- L-Dopa bean is a levodopa source.
- Several medicine interactions.
- Ask your doctor first.
Tinnitrol takes a two-sided approach to hearing support: the ear itself and the brain that processes sound.
The six ingredients at a glance
| Ingredient | What it is | Why it's included |
|---|---|---|
| Alpha-GPC | Choline compound | Cognitive function |
| GABA | Calming neurotransmitter | Relaxation, stress |
| L-Dopa bean | Natural levodopa source | Dopamine production |
| Moomiyo | Mineral-rich resin | Vitality |
| L-Arginine | Amino acid | Blood circulation |
| L-Tyrosine | Amino acid | Stress resilience |
Each ingredient explained
Alpha-GPC
Provides choline for acetylcholine, a messenger in memory, attention and nerve signaling. It has been studied for cognitive function, mainly in older adults.
GABA
The brain's main calming messenger. Small studies have explored GABA supplements for stress and sleep.
L-Dopa bean (Mucuna pruriens)
A tropical legume naturally rich in levodopa, which the body converts into dopamine. Dopamine plays a role in attention, mood and how the brain filters sound; research on ear ringing is limited and mixed.
Moomiyo (shilajit)
A resin from high mountain rocks, rich in fulvic acid and minerals, traditionally used for vitality.
L-Arginine
Used to make nitric oxide, which helps blood vessels relax. The inner ear relies on a healthy blood supply.
L-Tyrosine
A building block of dopamine and noradrenaline, studied for mental performance under stress.
Important safety notes
- L-Dopa bean: not with Parkinson's medicines, MAO inhibitors, antidepressants or antipsychotics; avoid with a history of melanoma or psychosis
- L-Arginine: may lower blood pressure
- L-Tyrosine: may interact with thyroid medicines
- GABA: may cause drowsiness
- Alpha-GPC: an observational study linked long-term use to higher stroke risk
- Not for pregnancy, breastfeeding or under 18
