LDN is a safe, non-toxic and inexpensive drug that helps regulate a dysfunctional immune system. It reduces pain, and fights inflammation. It is used to treat cancers, autoimmune diseases, chronic pain, gastrointestinal disorders, and mental health issues, to name a few.

Understanding how LDN works requires a grasp of three fundamental biological principles.

First, opiate receptors are present in multiple biological systems in the human body, as they regulate a great number of biological functions via the central release of natural opiates (endorphins/met-enkephalins).

Second, a class of proteins called toll-like receptors (TLRs) are part of the immune system, providing a first line of defense against microbial invasion and possessing the ability to recognize and be activated by not only pathogens but also endogenous signaling molecules.

Lastly, naltrexone, when given at a low dose, has antagonistic activity in both of these areas, and is able to modify biological functions of these receptor groups by suppressing unwanted immune reactions, or by stimulating disease-suppressed immune activity.
