What is LDN - low dose naltrexone
Low-dose naltrexone (LDN) is a safe, inexpensive, yet underused drug that is extremely beneficial for people with conditions marked by immune system dysfunction.

However, more than 20 years ago it was discovered that very small doses of this drug—3 to 4.5 mg—have profound effects on the immune system. How Does Low-Dose Naltrexone Work? LDN works by boosting levels of endorphins (peptides produced in the brain and adrenal glands) that are best known for relieving pain and enhancing your sense of well-being. Endorphins are responsible for the “runner’s high” brought on by strenuous exercise . These natural peptides are also powerful modulators of the immune system. When you take LDN at bedtime, it attaches to opioid receptors in the brain and in all types of immune cells, which temporarily blocks endorphins from attaching to them. This signals your body to increase endorphin production. The increased endorphin production helps orchestrate the activity of stem cells, macrophages, natural killer cells, T and B cells and other immune cells. It also prevents immune system overactivity , which is the crux […]
