Low Dose Naltrexone
Immune Balance. Natural Resilience.
Oral tablet · nightly
A low dose. A different medicine.
Naltrexone was originally FDA-approved at 50 mg to block opioid receptors in addiction medicine. Compounded at just 1.5–4.5 mg—roughly one-tenth the standard dose—it behaves like a completely different drug. At these microdoses, LDN briefly touches opioid receptors at night, then lets go. The body responds by producing more of its own endorphins, enkephalins, and regulatory signals—recalibrating the immune system and quieting low-grade inflammation rather than suppressing it.
The essentials
Your protocol, step by step
ENDORPHIN REBOUND
Low Dose Naltrexone (LDN) transiently blocks opioid receptors for a few hours. When the blockade wears off, the body overcompensates by producing more endorphins and enkephalins—natural mood-regulating and immune-supporting peptides.
IMMUNE MODULATION
LDN modulates microglial activity in the brain and peripheral immune cells, reducing pro-inflammatory cytokines. This makes it beneficial for autoimmune conditions, chronic pain, and neuroinflammation.
GLIAL CELL REGULATION
By calming overactivated microglial cells, LDN may reduce neuroinflammation and support healthier brain function—with emerging evidence for benefits in fatigue, mood, and cognitive clarity.
