I was sitting next to a nutritionist on a plane last night. He noticed my ear plugs and said it was good to see a young person taking care of his ears.
After telling him I was a sound engineer he began to tell me ways to maintain hearing health.
Niacin (B3) is a vasodilator and is especially good for the capillaries in the head, ears and cochlea, and may reduce the risk of tinitus.
Ginkgo is also a good supplement to take.
Thought I would pass on the info to you soundies, if you didn't know it already.
To your health,
Ben
