EP 108: LDN Explained: Benefits, Dosing, Cravings, and What It’s Not Good For
Episode Summary
In this episode of Longevity Unlocked, Coach Kyle and Dr. K break down Low-Dose Naltrexone (LDN)—what it does, what it doesn’t do, and when it actually makes sense to use. They explain how LDN works primarily by reducing inflammation through multiple pathways and lowering reward-driven cravings, including sugar, food, and alcohol cravings.
The conversation clarifies why LDN should be viewed as a temporary tool or “bandage”, not a cure or a longevity drug. Kyle and Dr. K discuss realistic expectations, proper dosing, cost considerations, and why LDN works best when used alongside root-cause treatments rather than replacing them. They also explore niche applications such as using LDN to ease cravings when tapering off GLP-1 medications.
The episode expands into standard-dose naltrexone and its evidence-based role in reducing alcohol cravings by rewiring reward pathways over time. Listeners walk away with a clear, practical understanding of how to use LDN responsibly, avoid overpaying, and decide whether it fits into their broader health strategy.
Key Takeaways
LDN primarily reduces inflammation and cravings.
LDN is not a cure and not a primary longevity medication.
It is best used as a temporary tool while addressing root causes.
LDN can help with chronic fatigue, chronic inflammation, and unexplained symptoms.
Typical starting dose is ~0.5 mg, slowly titrated upward.
Doses above ~5 mg are no longer considered “low dose.”
Expected benefits are subtle, not dramatic.
LDN may reduce sugar and food cravings via dopamine modulation.
It can help stabilize appetite when tapering off GLP-1 medications.
Most people stay on LDN for months to a few years.
LDN should cost about $1 per capsule from a compounding pharmacy.
Regular-dose naltrexone (50 mg) can reduce alcohol cravings.
Alcohol protocols require continued drinking for brain rewiring.
Cravings typically decrease gradually over 4–8 months.
LDN should never be used with opioids due to withdrawal risk.
