A low folic acid level or high homocysteine linked to age related hearing loss
The Blue Mountain Hearing Study included 2,956 people aged 50 or older. It was conducted by researchers from the University of Sydney. The data shows that if blood folic acid levels were below 11 nanomoles per liter there was a 34% increased risk of age related hearing loss. Homocysteine levels over 20 micromoles per liter were associated with a 64% increased risk of hearing loss. The study is published currently in the Journal of Nutrition.
