Low Dose Naltrexone and Weight Management: What the Research Actually Says

Learn what emerging research says about low dose naltrexone (LDN) for supporting appetite awareness and behavior consistency. Eden-affiliated providers may include LDN in personalized, provider-directed care plans for eligible adults.

Key takeaways
  • Low-dose naltrexone (LDN) is not FDA-approved for weight loss or appetite regulation.
  • However, research suggests it may affect the brain’s reward and inflammation pathways, potentially influencing behavior and motivation.*
  • Some licensed healthcare providers on the Eden platform may recommend compounded protocols that include LDN to support behavior, motivation, or appetite awareness as part of non-stimulant or post-GLP-1 care plans.
  • LDN is often well tolerated, but individual results vary.

*Structure-function claims are based on observed mechanisms; not intended to treat or cure disease.

What Is Low Dose Naltrexone (LDN)?

LDN refers to naltrexone prescribed at lower doses (1.5–4.5 mg/day)—a fraction of the 50 mg standard used for opioid and alcohol dependency.

At low doses, it's thought to:

  • Temporarily block opioid receptors
  • Stimulate endorphin release
  • Influence dopamine and reward signaling, which may impact food-related cues*

What the Research Says About LDN and Weight

  • There is no clinical trial proving that LDN alone causes weight loss.
  • Some small observational studies and case reports suggest potential benefits for:

    • Reducing reward-driven eating patterns*
    • Supporting behavior consistency*
    • Enhancing motivation for lifestyle adherence*

These mechanisms may support efforts related to weight management, particularly when emotional or habitual patterns are a factor. However, controlled research is still needed.

In FDA-approved Contrave®, naltrexone is combined with bupropion. However, the clinical effects cannot be attributed to LDN alone.

Eden’s Approach to LDN: Everyday+ Weight

Licensed providers working with Eden may recommend LDN as part of a provider-directed care strategy to support behavioral or emotional wellness.

These blends may support:

  • Awareness of emotional or habitual eating
  • Appetite stabilization during medication transitions
  • Motivation and mood regulation*

Other active ingredients may include:

  • Inositol
  • Acetyl-L-carnitine
  • Vitamins B6 and B12
    Optional additions (per provider discretion): acarbose, orlistat

*These uses are not FDA-approved. Medications are prescribed at the discretion of licensed providers based on individual clinical assessment.

Q: Will LDN make me lose weight?
A:
LDN is not a weight loss drug and is not FDA-approved for that purpose. However, for some people, it may help address underlying behavioral patterns that contribute to weight challenges. Eden providers focus on mood and habit support, not guaranteed weight outcomes.
