NAC
Precursor to glutathione, the body's master antioxidant. Originally a mucolytic drug, now used for liver protection (acetaminophen overdose antidote), respiratory health, and cochlear protection. One of the most versatile supplements.
Supplements for Tinnitus
Perception of ringing, buzzing, or other sounds without an external source. Affects ~15% of adults globally.
Magnesium glycinate
The most bioavailable form of magnesium for sleep and relaxation. Glycine itself has calming properties. US Army studies showed magnesium reduced noise-induced hearing damage. Addresses widespread deficiency — estimated 50% of Americans are magnesium deficient.
Ginkgo biloba
The most-studied supplement specifically for tinnitus. Improves cochlear blood flow. Cochrane review found mixed evidence, but European trials show benefit with standardized EGb 761 extract. Widely prescribed in France and Germany.
Melatonin
Endogenous hormone regulating circadian rhythm. Specifically studied for tinnitus-related sleep disruption, with some evidence for reducing tinnitus perception itself. One of the most evidence-backed sleep supplements.
Zinc
Essential trace mineral involved in over 300 enzymatic reactions. Zinc deficiency is linked to tinnitus in multiple studies. Also critical for immune function, wound healing, and retinal health.
Vitamin B12
Essential vitamin for nerve function and DNA synthesis, commonly deficient in older adults, vegans, and people taking certain medications. Deficiency causes reversible cognitive problems and may contribute to tinnitus. Methylcobalamin form preferred for neurological conditions.
N-Acetyl homotaurine
Neuromodulatory compound that blocks excitatory brain signals (NMDA) while enhancing calming ones (GABA). The prescription form acamprosate treats alcohol dependence, while OTC homotaurine is studied for tinnitus relief and brain protection. Limited but promising evidence for auditory conditions.
Acetyl-L-carnitine
Brain-penetrating form of L-carnitine that supports neuronal mitochondria. Multiple clinical trials show modest but consistent benefits for age-related cognitive decline, depression, and neuropathy.
B-Complex
Comprehensive blend of all eight B vitamins supporting cellular energy production, nervous system function, and methylation pathways. Quality varies dramatically between brands — look for active forms like methylfolate and P5P.
Vitamin B6
Essential B vitamin involved in over 100 enzyme reactions, particularly neurotransmitter synthesis. The active P5P form bypasses conversion issues, while high doses of synthetic pyridoxine can paradoxically cause the neuropathy it's meant to prevent.
GABA
The brain's primary inhibitory neurotransmitter. Oral supplementation is controversial — debate over whether it crosses the blood-brain barrier. Some evidence for stress reduction and sleep onset.
L-Theanine
Amino acid found naturally in green tea. Promotes alpha brain wave activity associated with calm alertness. Reduces anxiety without sedation. May help tinnitus via stress/anxiety reduction pathway.
Riboflavin
Riboflavin (vitamin B2) is essential for energy production and acts as an antioxidant cofactor. It's most famous for preventing migraines at high doses (400mg daily), though this use is off-label. Deficiency can affect nerve function, potentially including auditory nerves.
Lipo-Flavonoid
Heavily marketed specifically for tinnitus. Contains bioflavonoids and B vitamins. Despite ubiquitous advertising, clinical evidence for tinnitus relief is minimal. One small, older trial cited by the manufacturer; no independent replication.
Taurine
Conditionally essential amino acid abundant in brain, heart, and muscle. 2023 Science paper showed lifespan extension across multiple species. Supports GABA-ergic signaling and cardiovascular function.

Beyond supplements
There are other evidence-based interventions studied for tinnitus:
- CBT for tinnitus The most evidence-supported intervention overall. Cochrane review confirms benefit for distress and quality of life.
- Sound therapy / TRT Tinnitus Retraining Therapy combines counseling with broadband noise. Multiple RCTs support efficacy.
- Notched sound therapy Frequency-filtered music targeting the tinnitus pitch. Emerging evidence from German university trials.
- Acupuncture Mixed evidence. Some trials show benefit; systematic reviews are inconclusive.
