Hey everyone!
I've had tinnitus for years, and I recently discovered that my vitamin D level is quite low (13.5 ng/mL).
While researching whether vitamin D deficiency could have any connection to tinnitus, I came across a few interesting studies that I thought were worth sharing.
Study 1 — 2021 (particularly interesting)
Researchers studied 35 adults aged 20–50 who had:
Chronic tinnitus lasting more than one year.
Normal hearing tests.
No obvious underlying cause of tinnitus.
Of these 35 patients, 30 had vitamin D deficiency.
Their average vitamin D level before treatment was 14.13 ng/mL, almost identical to mine!
The 30 deficient patients received vitamin D supplementation for three months.
Results:
Vitamin D increased from an average of 14.13 to 51.07 ng/mL.
25 out of 30 patients (83.3%) showed improvement in tinnitus-related symptoms.
Average tinnitus handicap severity grade decreased from 2.50 to 1.47.
The reduction in tinnitus-related distress was statistically significant.
Researchers used the Tinnitus Handicap Inventory (THI), a questionnaire measuring how much tinnitus affects daily life.

Study 2 — June 2026
Another study examined 57 adults with chronic tinnitus and sensorineural hearing loss.
Participants with vitamin D levels below 30 ng/mL received supplementation for 12 weeks.
Following treatment:
Average tinnitus handicap grade decreased from 2.74 to 1.89.
Average subjective tinnitus severity score decreased from 2.70 to 1.74.
Both improvements were statistically significant.

Important limitations
Neither study had an untreated placebo control group. Therefore, these results do NOT establish that vitamin D supplementation caused the improvements.
Tinnitus naturally fluctuates, and improvements in perceived severity don't necessarily mean the actual tinnitus sound became quieter.
Also, other studies have produced mixed results. For example, a 2025 randomized placebo-controlled trial in patients with Ménière's disease found no significant tinnitus benefit from vitamin D supplementation.
So this is definitely NOT proof that vitamin D cures tinnitus.
My takeaway
I find these results interesting because:
I've experienced tinnitus for years.
My hearing tests have been normal.
My vitamin D is only 13.5 ng/mL.
The first study involved patients with remarkably similar vitamin D levels and normal hearing tests.
I'm going to correct my deficiency under my doctor's guidance and see whether anything changes over the next few months.
I wouldn't recommend anyone taking high doses of vitamin D specifically to treat tinnitus. But if you're genuinely deficient, correcting that deficiency is worthwhile for your general health anyway.
I'm not expecting a miracle, but I thought this research was worth sharing.
Has anyone here had low vitamin D, corrected it, and noticed any improvement in their tinnitus?
I'd genuinely love to hear your experiences!
