Ringing, buzzing or humming in the ears is common. It is a symptom with many possible causes, not a single condition.
See a doctor or audiologist if ringing is new, persistent, in one ear only, pulses with your heartbeat, or comes with hearing loss or dizziness. Seek care urgently for sudden hearing loss.
We are not aware of a supplement proven to eliminate ear ringing. Claims to the contrary should be treated with caution. A proper evaluation can find treatable causes, and clinicians can discuss sound therapy and coping strategies.
Protect your ears from loud noise, keep a regular sleep routine and use background sound at bedtime if silence bothers you.
