Axons are usually surrounded by a fatty substance called myelin. Myelin allows action potentials to propagate quickly from one neuron to another, allowing for rapid signal transmission. It is a critical part of the nervous system and it's absence has devastating effects, as seen in conditions such as multiple sclerosis.
Omega 3 Fats & Vitamin D as Vitamins for Hearing. The high levels of omega 3 fats and Vitamin D generally found in fish, such as salmon, tuna, trout or sardines, can have highly positive effects on hearing loss. Studies have shown that adults who ate fish twice a week had a 42% lower chance of facing age-related hearing loss than non-fish eaters.
DAILY VITAMIN SUPPLEMENTS FOR HEARING LOSS. 1  Ear, nose, and throat specialists will sometimes recommend up to 300 milligrams of niacin (vitamin B3) to increase blood flow to the microcapillaries of the inner ear, which feed the auditory nerve. Taking niacin can cause a heat flush lasting for about 30 minutes. N-acetylcysteine (NAC; 500 milligrams) may help prevent hearing loss-this is especially useful for people who are constantly exposed to loud noise. Taking folate (folic acid; 400 micrograms) on a daily basis has been shown to slow hearing loss.[1][2]
