Low Dose Naltrexone — or LDN — is naltrexone used at a fraction of the dose traditionally prescribed for addiction treatment. At these lower doses (typically 1.5mg to 4.5mg), it works differently in the body. Instead of blocking opioid receptors long-term, it creates a brief blockade that signals your body to produce more of its own endorphins and helps regulate immune function.

This makes LDN particularly interesting for people dealing with chronic inflammation, immune dysregulation, and a range of conditions that conventional medicine often struggles to fully address.

LDN is an FDA-approved medication used in an off-label capacity at low doses — a common and legal practice in medicine. It has been studied and used clinically for decades.
