multiple animal studies have shown that a common pathway for inner ear hair cell loss is damage from oxidative radicals. I identified 6 studies in animals that credibly show that astaxanthin is an antioxident that offers protection against oxidative injury to the inner ear. I could not find any human studies that support or refute that there is a benefit to humans. By contrast, there is substantial evidence that vitamin D3 offers protection in animals and humans.

Astaxanthin also comes in 2 mg, 4 mg, 10 mg, and upward. I recommend starting at a lower dosage , once a day, because, like I mentioned above, I learned after just a few days that I'm allergic to Astaxanthin. However, I now take Antarctic Krill Oil , and it contains astaxanthin. Each softgel of this Krill Oil contains 200 MicroGrams of Astaxanthin, so I can still consume astaxanthin, but in a lower dosage than with pure Astaxanthin. I now use it 2 or 3 days a week, 2 or three softgels each day , and my intake of Astaxanthin is now .4-.6 mg each day I use it. My allergy doesn't affect me as it seriously did with 4mg-10mg, and I still notice benefits in my inner ear and eyesight.

For Tinnitus, try Astaxanthin 2 mg 1 softgel per day. This helped me until I learned that I'm allergic to it. Nevertheless, Astaxanthin can not only relax your inner ear, but it's beneficial to your eyes as well.
