N-acetylcysteine is a precursor of glutathione an antioxidant that helps prevent cellular damage and is commonly used to treat hearing loss. Magnesium can be found in spinach, almonds, and many plant foods, taurine, an amino acid, can be found in meat and dairy, and B12 can be found in animal products. All of these nutrients are important for hearing loss, but whether a supplement is needed is a judgement call based on your diet.
