Low Dose Naltrexone (LDN)

Prescription low-dose naltrexone designed to enhance immune function, reduce chronic inflammation, and support energy, pain relief, and long-term resilience.

Low Dose Naltrexone helps balance immune activity strengthening defense without driving chronic inflammation.

LDN helps restore daily energy, reduce inflammatory fatigue, and promote long-term vitality.

Supports healthy mood and stress regulation by naturally increasing the body's own endorphin levels.

Supports whole-body balance by calming inflammation and strengthening immune function—with clinical guidance you can trust.
Follow The Science

Enhance Immune Function & 
Cytokine Balance

Modulates immune signaling and normalizes cytokine production to support resilience against chronic inflammation, autoimmune flares, and long COVID symptoms.

Improve Energy & Combat Fatigue

Restores daily energy and cognitive stamina by reducing oxidative stress and inflammatory load. Helps combat fatigue associated with autoimmune and post-viral conditions.

Reduce Chronic Pain & Inflammation

Inhibits glial and TLR4 pathways to relieve inflammation-driven pain associated with fibromyalgia, arthritis, and post-viral syndromes.

Boost Endorphins & Mood 
Regulation

Temporarily blocks opioid receptors, increasing endorphin production to support improved mood, emotional regulation, and restorative sleep.

Protect Brain & Cognitive Function

Calms microglial activation in the brain—helping reduce brain fog, support memory, and maintain long-term cognitive function.

Support Mitochondrial Health

By reducing inflammation-induced oxidative stress, LDN helps preserve mitochondrial integrity—supporting cellular energy, repair, and resilience.

To affect longevity, we must understand its pathways

Inflammation Reduction

Inflammation Reduction

LDN fine-tunes immune responses to counteract chronic "inflammaging," offering a pathway to healthier aging by reducing inflammation's negative effects on the body.

Endorphin Systems

Endorphin Systems

LDN increases natural endorphin production, potentially affecting aging pathways tied to mood, pain perception, and overall well-being through the body's natural painkiller system.

Oxidative Stress

Oxidative Stress

LDN reduces oxidative stress by enhancing the body's antioxidant defenses against harmful free radicals, slowing cellular wear and tear for more resilient aging.

Autoimmunity

Great experience with Healthspan

I’ve had a great experience with Healthspan. All of the representatives have been extremely responsive when sending messages on the portal, and I had a great call reviewing my initial labs with Brandon Fell who was extremely knowledgeable and courteous. I’ve started the Rapamycin and Acarbose protocol, and I’m looking forward to seeing what my updated labs will show in a couple months!

Frequently asked questions

What is Low Dose Naltrexone (LDN)?

LDN is a low-dose formulation of naltrexone used to enhance immune function, combat fatigue, and reduce chronic inflammation in autoimmune and pain-related conditions.

How does LDN work in the body?

LDN temporarily blocks opioid receptors, prompting the body to increase its production of endorphins. It also inhibits TLR4 and reduces microglial inflammation—lowering chronic inflammation and oxidative stress.

What conditions may benefit from LDN?

LDN is used off-label to support fibromyalgia, long COVID, MS, Crohn’s disease, rheumatoid arthritis, and chronic fatigue-related conditions. Study →

Is LDN FDA-approved?

Naltrexone is FDA-approved at higher doses for substance use disorders. LDN is prescribed off-label for reducing chronic inflammation, immune support, and chronic pain.

When will I feel results?

Some users report better sleep or mood within 1–2 weeks. Most experience significant results in energy, inflammation, and cognitive function by 6–8 weeks.

Can I combine LDN with other Healthspan protocols?

Yes. Many clients use LDN alongside Rapamycin, Methylene Blue, or Oxytocin for multi-pathway support.

Are there any side effects?

LDN is generally well-tolerated. Mild side effects like vivid dreams, nausea, or temporary sleep disturbances may occur and usually resolve quickly.

Can I take LDN with other medications?

Avoid concurrent use with opioids. Always consult your Healthspan clinician to check for drug interactions.

What is the typical dosage?

Starting doses range from 1mg–1.5mg, titrated to 4.5mg daily based on tolerance and response.

How long should I take LDN?

Most users benefit from 6–12 months of consistent use. Long-term use may help maintain results for chronic inflammation and fatigue.
