Vitamin B12

Reviewed by the Nimbera editorial team · Last updated May 2026

A study (Shemesh et al. 1993) found 47% of tinnitus patients with noise-induced hearing loss had B12 deficiency, and some patients experienced improvement following B12 replacement therapy.$10-$20 per month

How to use

Take 1,000 mcg of methylcobalamin (the active form of B12) sublingually or orally each day. If testing confirms deficiency, doctor-administered B12 injections are more effective for rapid correction. Retest levels after 3 months.

How it works

Vitamin B12 is essential for myelin sheath maintenance around auditory nerve fibers. Deficiency impairs neural signal conduction in the cochlea and auditory pathways, and correcting this deficiency may reduce neurally-driven tinnitus in those who are deficient.

Where to buy

Pharmacies, health food stores, Amazon - brands like Jarrow Formulas Methyl B-12, Solgar Methylcobalamin, or Country Life. Sublingual tablets absorb better than standard capsules.

Typical cost: $10-$20 per month

Safety notes

B12 supplementation is very safe and excess is excreted in urine. Most benefit is seen in those with confirmed deficiency. Vegans and older adults are at highest risk of deficiency. If supplementing long term, consider a B-complex to keep B vitamins balanced.
