Introduction

Low Dose Naltrexone (LDN) is an emerging therapy in functional medicine, valued for its potential to support patients with autoimmune conditions, chronic pain, and inflammation. For individuals in San Antonio, Texas and Quincy, Illinois, functional medicine providers are increasingly incorporating LDN into integrative treatment plans.

This article will cover what LDN is, how it works, evidence behind its use, and how patients in San Antonio, Quincy, and beyond can access functional medicine services offering LDN.

What Is Low Dose Naltrexone (LDN)?

Naltrexone, originally developed to treat opioid and alcohol dependence, has a unique effect when prescribed at very low doses (typically 0.5–4.5 mg). Unlike standard doses, LDN can:

• Support immune system balance

• Reduce chronic inflammation

• Increase endorphin production

Functional medicine providers often use LDN off-label to support patients with:

• Autoimmune diseases (rheumatoid arthritis, multiple sclerosis, Hashimoto’s thyroiditis)

• Chronic pain (fibromyalgia, CRPS)

• Inflammatory bowel disease (Crohn’s disease, ulcerative colitis)

• Chronic fatigue and post-viral syndromes

  
  

Clinical Evidence for LDN

Research on LDN has expanded in recent years:

• Fibromyalgia: Clinical studies show reduced pain and improved quality of life.

• Crohn’s Disease: Pilot studies suggest reduced disease activity and improved remission rates.

• Multiple Sclerosis: Early data points to improved symptom control and immune regulation.

While larger randomized controlled trials are needed, LDN is considered safe, affordable, and well-tolerated, making it a promising adjunct in functional and integrative medicine.

How LDN Works in Functional Medicine

From a functional medicine perspective, LDN works through several pathways:

1. Endorphin Regulation – Enhances the body’s natural pain- and mood-regulating chemicals.

2. Neuroinflammation Control – Calms overactive microglial cells in the brain and spinal cord.

3. Immune Modulation – Shifts the immune system away from excessive inflammation, promoting balance.

   
   

Limitations and Considerations

• LDN is not FDA-approved for chronic conditions—it is used off-label.

• Dosing is highly individualized; starting dose and titration vary by patient.

• Benefits may take weeks to months to become noticeable.

Because of these factors, patients are encouraged to work with a provider trained in functional and integrative medicine.
