LDN - SCIENCE & RESEARCH
Naltrexone is an oral medicine that—at high doses—helps control cravings for opioids and alcohol; it also helps to diminish withdrawals due to these substances
Low Dose Naltrexone (LDN) refers to prescribed doses below 10mg per day (4.5mg/daily is most common)
At low doses of 10mg per day or less, LDN is shown to reduce chronic inflammation, autoimmunity, obesity, fatigue, and chronic pain
FDA approved since 1985
Used successfully for over 40 years with an outstanding safety record
Hundreds of clinical studies show LDN to be a safe and effective treatment for many inflammatory-related diseases
Background & History
Lowers ESR (erythrocyte sedimentation rate), a marker of inflammation in the body
Increases natural endorphin levels
Strong clinical evidence in reducing chronic pain
Reduces fatigue and brain fog
May improve overall mood and feeling of well-being
May reduce food cravings
Encourages weight loss in some patients
Reduces chance of autoimmunity
Modulates the immune system
Note: LDN has not been approved by FDA for all use cases listed above, however, there are multiple clinical studies that have shown such benefits (see below). Learn more about "of label" uses
LDN Works on a Cellular Level to Increase Longevity
Endorphins are polypeptides made by the pituitary gland and central nervous system to moderate the production of neurotransmitters, such as serotonin and dopamine. Endorphins primarily help us to reduce pain and inflammation, promote autophagy, and cellular clean up.
In individuals with diagnoses such as depression, fibromyalgia, cognitive degeneration, and autoimmunity, consistent findings show chronically low levels of endorphins—specifically, low levels of an endorphin called the Opioid Growth Factor (OGF). OGF is an endorphin produced in most cells in the body to both influence and regulate cell growth, as well as immunity. When low levels of OGF endorphins exist, it is likely for individuals to develop immune system disorders. Low Dose Naltrexone (LDN) has been shown to increase OGF levels in the body, resulting in positive outcomes for those suffering from the aforementioned diagnoses.
How does it work? LDN first binds to opioid receptors. In doing so, it helps to displace the body’s naturally-produced OGF. As LDN displaces OGF receptors, affected cells become OGF-deficient and, as a result, three vital processes occur:
Receptor production is increased to try to capture more OGF
Receptor sensitivity is increased to capture more OGF
Production of OGF is increased to compensate for the perceived shortage of OGF
Since LDN will only block OGF receptors for three to five hours, the body experiences a rebound effect—which greatly increases the production and utilization of OGF. Once the LDN has fallen off the OGF receptors and excreted, the increased number of endorphins bind to the now more-sensitive and more-plentiful receptors. As a result, these new and improved receptors assist in regulating cell growth— promoting healing, reducing inflammation, and increasing immunity and autophagy.
Published Clinical Studies Showing Support for LDN:
RESEARCH & STUDIES
A case report and discussion published in Cureus: “Clinical trials have proposed a unique mechanism(s) allowing LDN to affect tumors including non-small cell lung cancer (NSCLC) at the cellular level by augmenting the immune system.”
A mouse study in Science Direct showed "Low-dose naltrexone inhibits colorectal cancer progression and promotes apoptosis…”
A review article in International Immunopharmacology concludes "Methionine enkephalin (MENK), was reported to modulate cell growth, MENK was identified as an opioid growth factor (OGF) that interacts with the OGF receptor (OGFr) and regulates cell proliferation…LDN increases production of MENK.”
A retrospective study published in the Journal of Clinical Psychopharmacology evaluates links between LDN and quality of life in 215 MS patients “77% of patients had no side effects at any time under LDN…60% of patients reported less fatigue while taking LDN…Three quarters of patients endorsed an improvement in quality of life.”
Two prospective pilot studies found that "naltrexone is a well-tolerated and likely effective treatment option in the community setting [and] may be an effective, safe, and inexpensive treatment for fibromyalgia.”
A cohort study showed additional support "Low-dose naltrexone reduced fibromyalgia symptoms in the entire cohort, with a greater than 30% reduction of symptoms over placebo."
A randomized, double-blind, placebo-controlled, counterbalanced, crossover trial assessing daily pain levels observed a significantly greater reduction of baseline pain in those taking low-dose naltrexone than in those taking placebo.
Crohn’s and Ulcerative Colitis
A study of Chron’s Disease patients published in the American Journal of Gastroenterology showed that after 4 weeks on 4.5mg LDN, 81% of patients exhibited a response to therapy and 67% achieved a remission (P < 0.001). Improvement was recorded in both quality of life surveys with LDN compared with baseline. No laboratory abnormalities were noted. The most common side effect was sleep disturbances, occurring in seven patients.
A 10-week crossover trial published in Biomedicines discovered “that LDN was associated with reduced plasma concentrations of pro-inflammatory interleukin cytokines, as well as transforming growth factor (TGF)-α, TGF-β, tumor necrosis factor (TNF)-α, and granulocyte-colony stimulating factor (G-CSF).”
Clinical Rheumatology published a review of multiple studies stating their findings that naltrexone “reduces the production of reactive oxygen species and other potentially neuroexcitatory and neurotoxic chemicals…and reduces ESR (erythrocyte sedimentation rate) a common marker of inflammation.”
A study on hyperandrogenic women found "that using Naltrexone actually helped to lower fasting insulin levels by up to 40%."
Another study of obese women showed that “Naltrexone may help to increase Growth hormone levels” which in turn helps develop lean body mass and increase ability to burn fat.
Naltrexone in combination with Buproprion “is more effective in inducing weight loss than Bupropion alone.”

SAFETY & SIDE EFFECTS
Most Common side effects of LDN:
During the first three to five days of taking LDN, you may experience mild to moderate levels of the above side effects. Side effects typically diminish on their own by day five. To reduce the risk of side effects, AgelessRx advisors recommend patients start with a ½ tab (2.25mg) for the first two weeks with a gradual increase to the 4.5mg dose.
Note: Please stop taking any dosage of Naltrexone a minimum of 48 hours before any surgical procedure or medical diagnostic requiring sedation, such as surgery or a colonoscopy. If you are not sure if you need to stop Naltrexone, please ask your doctor ordering the test or procedure. Additionally, Naltrexone cannot be taken in conjunction with opioids/painkillers. If you need to stop taking Naltrexone for a surgery, and accompanying pain killers are prescribed, you may resume LDN only 48 hours after you take your last painkiller.
