Low Dose Naltrexone (LDN) 1.5 mg vs 3 mg – What’s Right for You?
Table of Contents
What is Low Dose Naltrexone (LDN)?
Low Dose Naltrexone, commonly known as LDN, refers to daily doses between 1.5 mg and 4.5 mg of Naltrexone – a medication originally approved to treat opioid addiction. At low doses, however, LDN works very differently by modulating the immune system and reducing inflammation without affecting opioid receptors significantly.
How Does LDN Work?
LDN temporarily blocks opioid receptors for a short time each night. This causes the body to increase endorphin production, which improves immune function and reduces inflammation. This unique mechanism has shown promise in a variety of chronic and autoimmune conditions.
Conditions Treated with LDN
LDN is being increasingly used off-label for:
- ✔️ Multiple Sclerosis (MS)
- ✔️ Fibromyalgia
- ✔️ Crohn’s Disease and IBS
- ✔️ Hashimoto’s Thyroiditis
- ✔️ Rheumatoid Arthritis
- ✔️ Chronic Pain and Inflammation
- ✔️ Lyme Disease and Long COVID
