Prevent Noise-Induced Hearing Loss With A Supplement?


Researchers Found A Chemical That Protects Cochlear Nerves And Supports Mito Health

Researchers believe they found a supplement that can prevent noise-induced hearing loss. Nicotinamide riboside (NR) is considered a vitamin B3, and scientists at Weill Cornell Medical College and the Gladstone Institutes say that this compound can protect the nerve that feed the cochlea, which transmits sound information through those nerves to the spiral ganglion, which sends the information on to the brain. With exposure to loud noises, the synapses that connect the nerves to cells in the cochlea get damaged. This results in noise-induced hearing loss, according to Science Daily.

The researchers tested supplementing mice with NR before and after being exposed to loud noises. As hoped, NR was able to prevent damage to the nerves from loud sounds, a press released explained. As a result of the supplementation protecting the nerves, the researchers were able to avoid short term hearing loss and long term hearing loss. Interestingly, the supplementation was successful at preventing the hearing loss whether it was given before or after exposure to the loud noises.
