Low Dose Naltrexone (LDN)

What is LDN?
Low Dose Naltrexone (LDN) is a safe, well-tolerated therapy that works by gently modulating the immune system. Unlike standard high-dose naltrexone used for opioid addiction, LDN uses much lower doses (0.5mg–4.5mg) to regulate bodily systems without narcotic effects.

​

How It Works
LDN temporarily blocks opioid receptors, triggering the body to produce more endorphins—your natural "feel-good" hormones. This rebound effect reduces chronic inflammation, balances immune function, and interacts with Opioid Growth Factor (OGF) receptors that regulate cell growth and immune response.
