Cortisepin for Immune Modulation and Anti-Infective Defense
The immune benefits of cortisepin tie into its adenosine mimicry. Adenosine receptors exist on immune cells, and activation generally promotes an anti-inflammatory, tissue-protective state. Cortisepin's long half-life makes it a powerful systemic anti-inflammatory. In his practice, Dr. Sher uses it as a first-line supplement for patients with chronic complex medical issues and chronic inflammation, and they do 'fantastically well.' It is also his go-to for travel, along with methylene blue, because airports and airplanes are high-exposure environments. He emphasizes that while cortisepin is powerful, it works best when gut health, hormones, and foundational lifestyle are also addressed. Over time, the goal is to reduce dependency on such compounds by optimizing the underlying systems.
Cortisepin acts on adenosine receptors throughout the body, not just the brain. It suppresses NF-kappaB, a master inflammatory transcription factor, reducing systemic inflammation. It promotes mitochondrial biogenesis via AMPK, producing more energy for immune cells. By mimicking adenosine, it incorporates into viral RNA, causing chain termination and halting replication. It also upregulates NRF2, increasing endogenous antioxidant production.
Dr. Sher took it daily for a year and never got sick despite having four school-aged children. He also gives small pieces to his kids when they start feeling unwell, under his supervision. Ben Greenfield noticed sleepiness even with the immune formulation.
I took it for a year straight and I didn't get sick once in my house which is pretty unusual when I have four kids here that are you know in school and coming home sick on a reasonable clip.
