Quick answer: Age-related hearing loss comes from gradual damage to the delicate hair cells and nerves of the inner ear, driven by noise, oxidative stress, poor circulation and conditions such as diabetes and high blood pressure. Protecting your ears from loud noise is the single most important step. Nutrients such as magnesium, NAC, omega-3s and CoQ10 are being studied for inner-ear protection.
What damages hearing
- Loud noise from concerts, power tools and headphones
- Oxidative stress and inflammation
- Reduced blood flow to the inner ear
- Diabetes, high blood pressure and smoking
- Some medications that are toxic to the ear
Habits that protect hearing
- Use ear protection around loud noise
- Keep headphone volume moderate and take breaks
- Manage blood sugar and blood pressure (see heart health naturally)
- Regular aerobic exercise for circulation
- Do not smoke
Nutrients being studied
- Magnesium: studied for noise-induced hearing loss
- NAC: supports glutathione, an antioxidant in the inner ear
- CoQ10 and alpha-lipoic acid: support mitochondria in ear cells
- Omega-3s: support circulation
- Vitamin D: guided by testing
- Ginkgo: traditionally used for circulation and tinnitus; affects bleeding
Evidence for these nutrients is still early. Amounts should be individualized. If you work with me, the products I use are in my Fullscript dispensary.
Is testing helpful?
A hearing test by an audiologist is the starting point. Blood sugar, blood pressure and lipids matter for ear circulation. Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Hearing and healthy aging
Inner-ear cells rely heavily on mitochondria and are sensitive to oxidative damage. Hair cells that die do not grow back. Untreated hearing loss is also linked with faster cognitive decline, so protecting hearing protects the brain. Related: mitochondrial health.
When to see a naturopathic doctor
- You notice trouble following conversations
- You have ringing in the ears (tinnitus)
- You have diabetes or high blood pressure and want to protect your hearing
- You want a healthy-aging plan that includes hearing
See a medical provider promptly for sudden hearing loss in one or both ears. This is a medical emergency; early treatment can help.
Want a healthy-aging plan that protects your senses?
A free 15-minute consultation with Dr. Kneessi. No cost, no obligation. In-office in Odenton, MD or by telehealth.
Frequently asked questions
Can hearing loss be prevented?
Noise-induced hearing loss is largely preventable with ear protection. Age-related loss can be slowed by protecting your ears and your circulation.
Do supplements help hearing?
Some nutrients such as magnesium and NAC are being studied, but evidence is still early.
Is hearing loss linked to dementia?
Research links untreated hearing loss with faster cognitive decline. Hearing aids may help.
How loud is too loud?
Sounds at or above 85 decibels, about the level of heavy traffic, can damage hearing with prolonged exposure.
