Low zinc levels in the blood may compromise ear health, according to researchers at the Ankara Numune Research and Education Hospital in Turkey. Following a study of 28 subjects, researchers determined that oral zinc supplementation can provide support for healthy hearing. Study subjects were administered either 50 mg of zinc or a placebo daily for two months. At the end of the study favorable progress was detected in 46.4% of the subjects in the zinc group, leading researchers to conclude that zinc supplementation may play a beneficial role.
