What is LDN?
LDN is a safe, inexpensive, yet underused medication that is extremely beneficial for patients with any condition marked by immune system dysfunction. Naltrexone has been used in 50-100 mg doses for decades to help patients recover from addiction to alcohol, heroin and other opiate drugs. However, more than 20 years ago it was discovered that very small doses of this drug—1.5 to 4.5 mg—have profound effects on the immune system.
LDN works by boosting levels of endorphins and peptides produced in the brain and adrenal glands, that are best known for relieving pain and enhancing sense of well-being—they are responsible for the “runner’s high” brought on by strenuous exercise. These natural peptides are also powerful modulators of the immune system. When LDN is taken, it attaches to opioid receptors and temporarily blocks endorphins from attaching. This signals the body to increase production of endorphins, which helps orchestrate the activity of stem cells, macrophages, natural killer cells, T and B cells, and other immune cells. As a result, LDN enhances the body’s ability to fight disease.
