There is no scientific proof that dietary supplements can cure tinnitus there are many however, which claim that dietary supplements help to greatly reduce the level of the ring in their ears to a livable level.
Some of these supplements include:
Vitamin Mineral Supplements
Zinc Magnesium Vitamin A Vitamin C Vitamin E Vitamin B12
Zinc
Zinc is an essential mineral required for the proper functioning of cellular processes such as, the healing of wounds, maintenance of the immune system, cell division, and the senses of taste and smelling. Zinc is found heavily in the cochlea in the inner ear (the fine hairs on the nerve endings of the inner ear that senses sound vibrations) as well as in the auditory pathways of the brain. Zinc is also an essential component of the enzymes needed for the normal functioning of these areas.
Be aware there are risks of taking too much zinc, exceeding daily allowances for an extended period can weaken the immune system, lead to side affects such as disruption of coordination, nausea, and copper imbalance. If taking zinc supplements, take it separately from other minerals like, calcium, copper, and iron because they can interfere with the absorption of the zinc.
Magnesium
Magnesium, believed to help alleviate some of the damage to the cochlear hairs of the inner ear, which can become damaged when exposed to loud noises for prolonged periods. Magnesium is needed for many of the metabolic processes of the body.
Vitamins A, C and E
Some believe that taking vitamin A, C, and E along with Magnesium before exposure to loud noises can help prevent damage to the cochlear by helping to maintain the blood flow around the ears that is can be interrupted by the loud noises.
Vitamin B12
Vitamin B12 is needed for nerve and brain cell metabolisms and deficiencies can cause irreversible damage to the nervous system as well as the brain. People suffering from tinnitus also show deficiencies in Vitamin B12 and it is not known if taking Vitamin B12 to reduce the deficiencies will also reduce the tinnitus but it cannot hurt.
