Intranasal Insulin: A Breakthrough from TBI to Neuro-Enhancement

By Dr. Benjamin Busch, DO

Intranasal insulin (INI) has emerged as a promising therapy with a wide range of applications, from aiding recovery in traumatic brain injury (TBI) and stroke to serving as a potent tool for biohackers seeking neuro-enhancement. This new method delivers insulin directly to the brain by bypassing the blood-brain barrier. This allows for better health benefits. In this article, we will delve into the science behind INI, explore its benefits, and provide instructions on how to create your own intranasal insulin spray at home.

The Science Behind Intranasal Insulin

Intranasal insulin

Intranasal insulin administration leverages the olfactory and trigeminal nerve pathways, which offer a direct route to the central nervous system. This method circumvents the need for insulin to travel through the bloodstream and penetrate the blood-brain barrier, making it a highly effective way to deliver insulin to the brain.

According to research, intranasal insulin has shown significant potential in improving cognitive function and neuroprotection. It has been studied extensively for its effects on Alzheimer’s disease, with trials indicating that it can enhance memory and cognitive performance in individuals with mild cognitive impairment (MCI) and Alzheimer’s disease.

Benefits of Intranasal Insulin

Traumatic Brain Injury (TBI):

INI can help mitigate the effects of TBI by reducing inflammation and promoting neural repair. This can lead to improved outcomes and faster recovery for individuals who have suffered from brain injuries.

  • Reduction of Inflammation: One of the primary challenges in TBI recovery is managing inflammation. Intranasal insulin has anti-inflammatory properties that can help reduce swelling in the brain, thereby minimizing further damage and accelerating the healing process.
  • Neuroprotection and Repair: INI promotes the survival and growth of neurons, enhancing the brain’s ability to repair itself after injury. This neuroprotective effect can lead to improved cognitive and motor function over time.

Stroke Recovery:

Intranasal insulin has been shown to enhance recovery post-stroke by improving cerebral blood flow and reducing neuronal damage. This can significantly impact the rehabilitation process, leading to better functional outcomes.

  • Improved Cerebral Blood Flow: By enhancing blood flow to the brain, INI can help deliver essential nutrients and oxygen more efficiently, which is crucial for recovery after a stroke.
  • Reduction of Neuronal Damage: Stroke often leads to significant neuronal damage. INI helps protect neurons from further damage and supports their recovery, improving overall brain function.

Alzheimer’s Disease and Cognitive Decline:

Intranasal insulin has been studied for its potential to slow down or even reverse cognitive decline in patients with Alzheimer’s disease and mild cognitive impairment (MCI).

  • Memory Enhancement: INI has been shown to improve memory performance in individuals with MCI and Alzheimer’s disease by enhancing synaptic plasticity, which is essential for learning and memory.
  • Cognitive Function Improvement: Regular use of INI has been associated with better performance in cognitive tasks, improved attention, and overall mental clarity.

Neuro-enhancement for Biohackers:

Biohackers have taken a keen interest in intranasal insulin for its cognitive-enhancing properties. Studies suggest that INI can improve attention, working memory, and overall cognitive performance, making it an attractive option for those looking to enhance their mental capabilities.

  • Enhanced Working Memory: Biohackers report that INI helps in boosting working memory, which is critical for tasks that require mental effort and concentration.
  • Increased Attention and Focus: INI can enhance attentional control, allowing individuals to stay focused on tasks for extended periods.
  • Overall Cognitive Enhancement: Regular use of INI can lead to improvements in various cognitive domains, making it a popular choice among those seeking to maximize their mental performance.
