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.
Researchers have found that patients with low levels of folate in their blood are more likely to develop hearing loss (Gok 2004; Lasisi 2010; Gopinath 2010), and that low vitamin B12 levels are associated with hearing loss (Gok 2004) and tinnitus (Shemesh 1993).
For optimal benefits of the vitamins, studies have found that taking vitamin C (1,000-1,500 mg) and vitamin E (300-400 IU) helps to lower the risk of AMD.Reduce the risk of Alzheimerâs disease. A study involving nearly 5,000 participants looked at the combined effects of vitamin E and other antioxidants.or optimal benefits of the vitamins, studies have found that taking vitamin C (1,000-1,500 mg) and vitamin E (300-400 IU) helps to lower the risk of AMD.
