What are Low Dose Naltrexone (LDN) 3mg capsules?
Low Dose Naltrexone (LDN) 3mg capsules are a lower-dose version of naltrexone, a medication traditionally used in 50mg doses to treat opioid and alcohol addiction. LDN is specially compounded to deliver much smaller doses, typically between 1mg and 4.5mg, for alternative therapeutic purposes.
While higher doses of naltrexone block opioid effects, low doses are believed to regulate the immune system and reduce inflammation. LDN is commonly used off-label for conditions such as fibromyalgia, multiple sclerosis, Crohn’s disease, and other autoimmune or chronic pain disorders.
LDN is usually taken once a day and has gained attention for its potential to support symptom management in a variety of inflammatory and immune-related conditions. However, it is important to note that LDN is not yet officially approved for these uses and is prescribed off-label.
What is the active ingredient in Low Dose Naltrexone (LDN) 3mg capsules?
The active ingredient in Low Dose Naltrexone (LDN) 3mg capsules is naltrexone hydrochloride (3mg).
Naltrexone is a medication originally developed to treat opioid and alcohol dependence at much higher doses (typically 50mg). However, in smaller doses ranging from 1mg to 4.5mg, it is believed to help regulate the immune system and reduce inflammation. This makes LDN a potential treatment option for various autoimmune and chronic pain conditions, although it is prescribed off-label for these uses.

How does LDN work?
LDN temporarily blocks opioid receptors, triggering the body to produce more endorphins, which are natural pain-relieving chemicals. It also plays a role in immune system modulation, helping to regulate inflammation and improve immune responses in conditions linked to chronic inflammation or immune dysfunction.

LDN is commonly used to help manage:
- Autoimmune diseases – Multiple sclerosis (MS), lupus, rheumatoid arthritis, Hashimoto’s thyroiditis
