IGF-1 and Hearing Loss/Inner Ear Disorders

If you’re familiar with Nutronics Labs’ products, you know that IGF-1 is the major protein naturally found in deer antler velvet and has an impressive range of medicinal properties. It is used by people around the world (including physicians, athletes, and even celebrities) for its strengths, from helping support better heart, joint, and bone health to helping promote muscle growth.

It seems like we’re always hearing about fascinating new possibilities for IGF-1. In a new study published by Frontiers in Pharmacology this month, researchers at Kyoto University in Japan found that IGF-1 may be linked to better treatment options for hearing loss and inner ear disorders.

This particular study focused on the treatment of sensorineural hearing loss (SNHL). Also known as nerve-related hearing loss, SNHL occurs when there is damage to the inner ear or to the nerve pathways from the inner ear to the brain. People with this type of hearing loss typically have a reduced ability to hear faint sounds and follow conversations, especially with background noise. They may also feel dizzy or off-balance.

Nerve-related hearing loss is often treated with hearing aids or cochlear implants, but in most cases it cannot be permanently corrected through surgery or medicine. It is the most common type of permanent hearing loss and is considered an “intractable” disease because the hair and supporting cells in the inner ear cannot be regrown.

However, clinical trials have revealed some hope, with IGF-1 being a major player in this development. IGF-1 is actually naturally found in the human body. While it is primarily produced in the liver, it’s also one of the growth factors involved in the development of the inner ear.

Based on previous studies that showed that IGF-1 was successful in maintaining hair cell numbers (which, as mentioned above, cannot be replaced if damaged), a clinical trial sought to investigate the effects of IGF-1 on sensorineural hearing loss

Remarkably enough, researchers found that this was another area in which IGF-1 could deliver potential health benefits. According to the published review, “The proportion of patients showing hearing improvement was significantly higher in the IGF-1-treatment group at 24 weeks after treatment than in the control group.” A randomized clinical trial is now underway to compare the benefits of IGF-1 to those of other methods for hearing loss.

Of course, this is wonderful news to Nutronics Labs. We’ve always believed in the incredible potential of the IGF-1 found in our all-natural products, so it’s great to hear that even more benefits are being discovered and helping bring improved wellness to people everywhere.
